Frank Stettner b96051a507 conrad-digi-35-cpu: Remove CH1 from device. 
This device is write only and does not transmit any measurement data.
Therefore a channel is not necessary.

Gerhard Sittig 8e5dbaf6e9 dcttech-usbrelay: support conn=vid.pid specs in addition to paths 
Extend the scan code path, accept user provided conn= specs in the
"vid.pid" format. Everything else is assumed to be a hidapi compatible
"path" and may suffer from conn= parser limitations. Unfortunately the
hidapi API won't let us lookup paths from bus.addr specs which would
work when multiple cards need to be told apart.
 2021-07-23 19:58:46 +02:00
Gerhard Sittig 0498ef4e42 dcttech-usbrelay: accept conn= spec different from hidapi enum details 
Rework the scan and probe routines. Skip the USB enumeration's result
set when the user provided a conn= spec, instead exclusively open the
specified device. It's acceptable when this user spec does not match
the details which the hidapi enumeration would yield. [ This version
prepares but does not implement yet support for "funny" hidapi(3) paths
on platforms beyond Linux. ]

This also weakens the logic which determines the relay count from the
USB product string. Any trailing number is accepted. Which allows to use
compatible devices with differing vendor/product strings when conn= is
specified. The previous "USBRelay" prefix check remains in place for
automatic enumeration.

Beautify diagnostics, even phrase debug and spew level messages such
that they can be presented to users. Makes -l 5 look more consistent.

Gerhard Sittig 996331ce9b dcttech-usbrelay: rework scan (enumeration) and probe (identification) 
Move all of the sdi creation into the probe routine which communicates
to the relay card. Extend diagnostics in that code path. Which leaves
pure USB enumeration in the scan routine.

Gerhard Sittig e333a40c1c dcttech-usbrelay: adjust serial number and connection string logic 
Store the USB relay card's serial number such that users can tell apart
multiple connected cards. Hold the HIDAPI path in the 'connection_id'
member because 'conn' is something internal, not for display purposes.

Gerhard Sittig 59f6765508 contrib: add udev rule for V-USB based HID devices (USB relay card) 
Add the USB identification of the dcttech.com USBRelay<n> card. Which
happens to be shared with other V-USB based firmware projects. Thus is
rather generic. The USB relay card is just the first supported device
of that kind.
 2021-07-21 22:03:59 +02:00
Gerhard Sittig 321f85fb07 dcttech-usbrelay: implement multiplexer driver for USB relay card 
Implement support for the "www.dcttech.com USBRelay<n>" card. This V-USB
based HID device communicates HID reports to control up to 8 relays. The
driver depends on the HIDAPI external dependency for maximum portability.

Support for the conn= parameters is limited. A path that HIDAPI can open
is expected, which depends on the platform and HIDAPI implementation,
and may not always be expressed by means of sigrok command line options.
See README.devices for a discussion.

The USB serial number is not considered. This is an implementation
detail of the relay card's firmware. HID reports carry a five character
identifier for the board.

Relay state is cached in the driver. It's assumed that relay state won't
change outside of libsigrok control as long as the device is opened. The
single request to activate/deactivate all relays at once is supported.

Frank Stettner 569165c0e4 hp-3478a: Fix switching from 4-wire to 2-wire measurement. 
The measured quantity flags for the measurement mode can only contain one flag
at maximum. Therefore the quantity flags handling can be simplified, which also
fixes a bug when switching from 4-wire resistance measurement to 2-wire mode.

Frank Stettner 8ef4fb3347 hp-3478a: Only match when conn= is given to avoid false probe positives. 
The HP 3478A device would not reliably identify by means of SCPI queries. The
previous scan() implementation would have matched any connected SCPI device,
then upset these devices by emitting non-SCPI requests.

Tighten the scope of the hp-3478a probe, only scan for devices when a conn=
spec was provided. This avoids false positives and malfunction of other
devices, and still lets users address the problematic device. This is similar
to serial-dmm and unspecific cables and has proven to work there.

Frank Stettner 0e3c3c80b8 scpi_vxi: Unbreak MacOS build (vxi.h inclusion order). 
Undo the #include statement order change of commit 7414fb55cb. It's
essential on MacOS to include vxi.h early to keep related u_long et al
data types available. See commit d40b8557a9 for a discussion.

Also drop the inclusion of rpc/rpc.h from scpi_vxi.c because it is not
used in that source file, instead is a vxi.h dependency and is included
there.

Daniel Anselmi ed78768225 scpi_vxi: fix memory leak for SCPI response data in VXI support code 
Routine scpi_vxi_read_data() invokes device_read_1(), which provides a
static buffer where dynamically allocated memory for SCPI response data
is kept. Release this memory after getting a copy of the response data,
before the next device_read_1() call loses the reference.

Gerhard Sittig 7414fb55cb scpi_vxi: readability nits in the SCPI via VXI source code 
Address style nits to improve readablity and future maintenance.
Move system header includes before application level includes. Move
assignments out of variable declaration blocks. Separate function calls
and assignments from error checks and flow control. Break a long line.
Add braces around conditional multi line statements.

All these adjustments are cosmetical. Behaviour does not change.

Gerhard Sittig 18426d1c0e scpi-dmm: add short measurement delay for 34465A 
With Keysight 34465A the VOLT:AC and FREQ functions keep suffering from
USB timeouts and pipe errors. Add a 10ms delay between initiating the
acquisition and checking for completion before fetching the result.

The weird thing is that when successful responses are seen after
temporary failure, enlarging the delay does not make them go away.
Instead the USB errors keep moving to a different spot. Measurements do
arrive though, so this is just annyoing but not a blocker.

Experimentation suggests that 200ms timeouts reduce the probability of
these USB communication errors. But if functions tend to respond that
differently, are delay time specs per MQ required? The implementation of
the driver currently assumes a single delay spec.

Gerhard Sittig e90551c3f8 scpi-dmm: model and MQ dependent delay before measurement 
Some models are slow to start a measurement acquisition in specific MQs
(meter functions). An "*OPC?" query went unanswered after "INIT" was
sent. This was observed on 34405A in temperature, frequency, resistance,
AC voltage and current mode.

Add an optional per-model measurement delay that is used when the MQ
specifies that the delay is applicable. Because functions are changed
rarely but measurements are taken many times, only the first reading
is delayed while later readings are seen at the expected interval. Not
delaying the first reading will result in device errors.

Declare a 2500ms measurement initiation delay for 34405A which was found
by experimentation. This is huge but was found to be necessary.

Of course all other meter functions are unaffected by this commit. As
are the meters which specify no delay.

Gerhard Sittig 08f023fe97 scpi-dmm: model and MQ dependent delay when switching functions 
Some models are slow to switch meter functions to specific MQs. This was
observed with 34405A and AC V/I modes, where USB connections timed out
and suffered from pipe errors.

Add an optional delay after "CONF:<mode> [<range>]" SCPI requests. The
duration of the delay is per model, the use of the delay is per MQ on
that model. The 200ms delay for 34405A was found by experimentation.

Speaking about 34405A: Only the "INIT" request in temperature mode
remains as an issue, which is not covered by this commit's approach.
 2021-06-01 08:20:59 +02:00
Gerhard Sittig b74cc88d32 scpi-dmm: use different Agilent SCPI command for range and measurment 
Don't use the "[SENS:]<mode>:RANGE..." request on Agilent protocol
speaking devices. Use "CONF:<mode> [<range>]" instead. This was tested
with all devices which reference this model.

In theory there is the question whether previously configured ranges
should be re-used when (exclusively) the MQ is switched. It's assumed
that this is not useful, instead users or their applications should
select the function first and optionally pick the range then. Re-use of
e.g. 10k resistance range when switching to capacitance might be seen as
confusing (and results in errors in the device).

Use the combination of INIT and FETCH? to get measurements. The READ?
request is more complex and might "undo" what INIT already initiated.
This improves perception of the 34405A meter's operation.

Gerhard Sittig bf03e06d57 scpi-dmm: rephrase read timeout decls, put "unit" after "ms value" 
Rephrase the SCPI read timeouts in scpi-dmm model declarations. Shuffle
the order of product terms such that the milliseconds "unit" goes last,
and the milliseconds value goes first. Assume that "2500 * 1000 [us]"
better reflects the intention than "1000 * 2500" does.

Gerhard Sittig a36b21fb89 fluke-45: drop serial port echo test, was disabled for years 
The Fluke 45 driver's ECHO_TEST broke other people's SCPI device
identification and was disabled in 2018-11. Remove the dead code which
is impossible to resurrect. Its purpose was questionable to begin with.

Should users be affected, then the echo would break the identification
phase. The check cannot be done before identification without affecting
other connected devices, cannot be done after the identification either
when that very identification systematically fails. Should a user meet
this condition then applications' logs are available to see why *IDN?
fails, assuming that users are not aware of their serial port or device
configuration. The request's reflection in the place of a response gives
a strong hint.

Improve readability and simplify maintenance of the sr_scpi_scan()
routine.

Move initial assignment and subsequent update of variables in closer
proximity, don't hide assignments in declaration blocks. Use common
helper code where available. Split complex conditions into individual
terms which are easier to review and reason about. Don't mix calls and
value checks and flow control in the same statement.

Gerhard Sittig d008c0273f hp-59306a: only match when conn= is given to avoid false probe positives 
The HP 59306A device was made in 1973 and would not reliably identify
by means of SCPI queries. The previous scan() implementation would have
matched any connected SCPI device, then upset these devices by emitting
non-SCPI requests.

Tighten the scope of the hp-59306a probe, only scan for devices when a
conn= spec was provided. This avoids false positives and malfunction of
other devices, and still lets users address the problematic device. This
is similar to serial-dmm and unspecific cables and has proven to work
there.

How to reproduce the issue:

While queries for the range are supported for voltage, current,

diode, continuity modes not only fail but even lose the USB connection

Although the 34405A does not support this function, other Agilent

without a unit or MQ associated with them. Support to list available

if desired in a future implementation.

Gerhard Sittig 7fcdc35e17 scpi-dmm: use INIT instead of MEAS for Agilent to start acquisition 
Though measurement values come in, the 34405A and 34465A meters kept

keyword was changed to INIT, which is used for other Agilent devices
using the HP protocol variant.

This change is acceptable because it was tested on all DMMs which use
the Agilent protocol (according to scpi-dmm profiles).

Gerhard Sittig cae328b54c scpi-dmm: move OPC availability check to after IDN device identification 
Assume that *IDN? requests don't involve expensive processing, and thus
don't require *OPC? before their execution. This makes scpi-dmm follow
the good tradition to only use non-standard or model dependent features
after the device was successfully identified. Which avoids confusion on
unrelated devices.

Exclusively check for *OPC? availability on Owon devices, because these
motivated the introduction of the test in the first place. This avoids
confusion on other devices where short timeouts result in errors because
the response is not retrieved although the command is supported (observed
on Agilent meters connected via USBTMC).

The SCPI get routines may allocate memory for response data which
callers have to free after use.

This implementation is incomplete. The fluke-45 driver's context holds
a "global" copy of the most recently received response. While the data
is freed in the next receive call, one item remains allocated for the
driver's remaining life time. Which is considered non-critical.

Also moves an operator in a complex multi-line expression to a different
location to follow the project's style.

Some of the SCPI getter routines allocate memory for response data which
callers need to free after use. Document this responsibility in more
places, and rephrase existing locations for consistency. See a word-diff
for the essence of the commit.

It's assumed that the separate paragraph in the function description is
better perceived than something that's hidden in the parameter or return
value discussion. Also reference the corresponding free routine by name
for callers' convenience (data types will differ among routines). Some
free routines can be called unconditionally, others require NULL checks
at the caller's.

Gerhard Sittig 7a78fd56f7 rdtech-dps: research to reduce serial comm transfer volume again 
The DPS devices default to a rather low UART communication bitrate. The
generous retrieval of more Modbus registers than strictly necessary for
the periodic acquisition of analog channel values and state tracking may
or may not be an issue.

Instrument all call sites in api.c to the device state gathering calls
such that the protocol.c side transparently can reduce the transfer
volume depending on which level of detail the caller may expect given
its current context. Under optimal circumstances this might cut the
traffic in half, which DPS devices may benefit from.

This commit adds the infrastructure to potentially reduce transfer
volume, but does not change behaviour. The "config" reasons may need
further partitioning if Modbus register access really turns out to be
a severe bottleneck. The API lends itself to that extension easily. The
approach which gets prepared in this commit needs to get runtime tested
by those who got access to the hardware.

Gerhard Sittig 884ae8c021 rdtech-dps: introduce support for RD6006 and other Riden RD models 
The RD devices differ from DPS devices in their default communication
bitrate (115200), register content endianess (BE), and register set
layout (addresses for registers). In either case 16bit registers get
accessed by means of Modbus communication over a serial channel. The
interpretation of the registers' values mostly is the same as for DPS
devices once a register with the same meaning got identified. Device
identification includes a 32bit serial number which DPS devices appear
to not provide.

All other product features are the same, and map to identical sigrok
mechanisms. That's why re-using the rdtech-dps driver to add rdtech-rd
support is considered desirable. This implementation shares all code
"above" the raw register addressing and raw value interpretation. All
logical processing, configuration interface, state tracking and data
submission to the session feed, are shared among the different device
types.

Declare support for the RD6006, RD6012, and RD6018 models. Their specs
were taken from the 2020.12.2 instruction manual. The driver was tested
with an RD6006 device (firmware version 1.28). Unfortunately automatic
device detection is not possible or will not be reliable, which is why
users need to specify the respective model by picking one of the two
drivers. Within a driver variant the device identification and use of
the device are automatically dealt with.

Gerhard Sittig d7a4dad881 rdtech-dps: layer separation between API and protocol, style nits 
The existing power supply driver for Riden DPS/DPH devices unfortunately
duplicated intimate details of modbus communication and register layout
including interpretation of raw register values across several source
files. Do separate the physical transport and the register layout and
register fields interpretation layers. This brings the driver in line
with the usual api.c and protocol.c arrangement of responsibilities, and
prepares the future addition of other similar devices.

Address a few style nits while we are here. Include <config.h> in all
source files, and alpha-sort include directives. Address minor data type
nits. Reduce indentation in code paths. Propagate more error codes.
Update comments which lagged behind the code, adjust grammer (eliminate
"actual" false friends). Eliminate a few magic numbers and redundancies,
switch to the more recent endianess aware byte stream reader API where
beneficial, to eliminate redundant offset math.

Other nits seem to have gone unnoticed before: The indices of all sigrok
channels were identical (all zero). Signed print formats were used for
unsigned data.

This implementation compiles, but wasn't runtime tested due to lack of
hardware. A rough estimate of transfer volume and transport throughput
suggests that the 10ms cycle time no longer can be kept, may end up
around 25ms (40 cycles per second). This can get avoided by adding more
code to tell the configuration requests, the acquisition start, and the
measurements grabbing during acquisition apart. It's assumed though that
the 10ms glib poll interval did not translate to such fast measurement
gathering. The firmware may typically provide data at lower rates anyway.

The generic source code may look overly complicated or redundant at
first glance, but compilers' generated code will greatly get optimized.
Simplified maintenance because of reduced cognitive load is considered
more important.

Gerhard Sittig f93bf8ba02 dmm/bm52x: unbreak build when serial comm is not available 
Make another code path in the Brymen BM52x packet parser optional which
snuck in earlier and broke compilation when serial_comm dependencies are
not met.

Ideally the src/dmm/ parser code would not get built at all in that
case, but building a parser with reduced functionality and not using it
later because its callers are conditional is as good, and is what other
DMM packet parsers did in the past.

Gerhard Sittig aa8e4959e2 ftdi-la: work around missing USB strings during device probe 
Some FTDI chip based products ship with EEPROM content which makes
libftdi fail to lookup the USB strings, which breaks the scan for the
device's presence. The previous implementation was strict and only
accepted the absence of a serial number. This implementation also copes
when vendor and model cannot be gathered from the device, and provides
fallback values based on VID:PID numbers.

Also factor out a magic number for string lengths. Stick with dynamic
allocation since 3x 32bytes would be rather huge a local stack use, and
future maintenance might bump that string length again.

Gerhard Sittig 6bee394dee serial-dmm: add support for the Brymen BM820s family 
The BM820s series uses the same 10000 counts protocol as BM520s does,
but lacks the capability of recording measurements. Re-use the bm52x
DMM packet parser, but don't register the config get/set/list and
acquisition start callbacks.

It turns out that the packet request and packet validity check routines
need to be individual, since 0x82 is used instead of 0x52 as a magic
number in some places. Fortunately the complex payload parser is shared
among BM520s and BM820s series. This was tested with a BM829s meter.

acquisition of live readings, or locally retrieve the selected "session
page" and forward its measurements to the session bus. These separate
code paths are required because the protocol differs a lot between these
modes, a totally different set of requests and responses is involved,
response interpretation logic is impossible to share between live and
recorded measurements.

Gerhard Sittig 070668a0fd serial-dmm: more DMM parser callbacks (open, var length, config, start) 
Extend the serial-dmm driver's common infrastructure to support more
per-parser (per-model) specific extensions. Add support for variable
length packets (motivated by BM85x), and pass the packet length to
parsers which accept it. Add callbacks which run after the COM port got
opened (motivated by BM85x). Add support for additional configuration
get/set/list properties (motivated by BM52x), including a hook into the
acquisition start and a state container which is owned by the parser.

Device specific acquisition start can check its local state which can
store the result of previous config get/set requests, and can arrange
for a different receive routine to execute (motivated by BM52x). The
default code path will execute serial-dmm's receive routine which keeps
invoking the DMM's packet parser for each registered display.

Prefer double precision values in the new parser callbacks. Also fixup
some data type issues: Use unsigned types for length and size specs as
well as timeouts, don't promote false booleans to NULL pointers, reduce
malloc() argument redundancy. Rephrase some instruction grouping and
update comments to simplify future maintenance. Get the current time
just once for improved consistency in the packet re-request code path.
Rename identifiers in the data reception path to improve readability.

Gerhard Sittig 1a7adeac29 serial: extend stream detect for variable length packet checkers 
The previous implementation of the packet detection in a serial stream
assumed that all packets are of equal length which is known in advance.
Extend the packet validity check interface such that caller provided
callbacks can either decide that the input is valid or invalid (terminal
decision), or request more receive data before a decision can be made
(deferral, coverring variable length packets, with a minimum size to
cover the header before a length becomes available and the total packet
length is known).

This commit extends the API, and adjusts the call sites to not break the
compilation. Actual variable length checkers are yet to be done. Improve
readability while we are here: Better reflect the purpose and units of
variables in their identifiers. Tweak diagnostics messages, update
inline and doxygen comments.

Gerhard Sittig ec30291701 input/vcd: suggest downsampling to users for reduced resource consumption 
Naive creation of VCD files with inappropriately fine timescale specs
results in excessive resource consumption due to libsigrok's assumption
of a constant rate stream of sample data. A workaround is available and
documented, but users need to become much more aware.

Implement a reliable check for wasteful input data situations which
depends on the reception of _all_ input data, and can only alert users
late after potentially spending lots of time and assuming that available
resources allow completion of the import. Users could miss that check's
outcome.

Also implement early checks which (necessarily) are based on weaker
conditions, to already raise user's awareness while data import still is
executing. Phrase these early checks as computationally inexpensive as
possible, to not affect the main task of data import too much. Avoid
false positives by balancing the desire for early emission of messages
and picking appropriate conditions to test for.

This commit implements the foundation for early estimates and reliable
terminal checks, as well as the emission of messages which support users
and allow a more effective use of the file format. The specific limits
and tested conditions still may benefit from more tuning in the future.

The input module logic in this commit emits an information for harmless
cases, and emits warnings for "severe" cases where default option values
or incomplete user specs result in several orders of magnitude higher
resource consumption than necessary. GUI users may not notice, but the
library cannot help that given the current infrastructure -- the library
stricly does as the application tells it to, according to user input.

The best use is to run the CLI's --show feature on VCD files of unknown
content, to get an idea how to most appropriately configure a subsequent
file import. An alternative is to open the VCD file before import, check
the timescale in the header and the last two timestamps, to get an rough
estimate of a useful downsample factor.

This is motivated by but does not resolve bug 1624.

Gerhard Sittig 358105152a input/vcd: unbreak U and - values for single bit input data 
The previous implementation already mapped L/H/U/- literals for input
data values to the 0/1/0/0 logic levels which sigrok can handle. But
missed these literals in the condition which dispatches real/integer,
bit vector, and single bit data types. Which made VCD import fail for
some of the files in the SpinalWorkshop repo.

Extend the test condition for single bit values. This unbreaks the

Reduce the message's log level from ERR to INFO when the serial stream

pulses which cannot get expressed with static "rts=1" etc phrases in
parameter strings, and allows handshake signal control while leaving
bitrate and frame format untouched. Applications specify which signals
to modify while other signals remain as they are (ternary input).

Do implement the signal manipulation in the libserialport transport,
do nothing and silently pass in the HID and BT transports. These can
get extended later as the need arises, depending on the HID chips' and
RFCOMM peers' capability to control these signals. This extension is
transparent to application code (acquisition device drivers).

Gerhard Sittig 400bc4ffab dmm/bm52x: introduce support for Brymen BM525s 
Introduce a bm52x DMM packet parser which is modelled after the bm86x
implementation, and hook it up to the serial-dmm driver. This supports
the live readings (real-time download) of the Brymen BM525s logging DMM.
The timing follows the vendor documentation (0.5s between requests, and
4.0s absolute timeout after request transmission). Reading previously
recorded data (memory data sets) unfortunately does not fit well into
the serial-dmm approach, and needs to get addressed differently later.

Gerhard Sittig e62b284c1c analog.c: rephrase analog feed to float conversion routine 
Rephrase the sr_analog_to_float() routine to further reduce redundancy.

Check early for a match of the input data and result format, to grab the
raw data without conversion in that case. Handle optional scale/offset
calculation in that fast code path, too.

Unify the instructions which convert input data from either integer or
floating point presentations to the result format. Use common stream
readers to retrieve input data in several formats, which eliminates
local conversion buffers. Move common sub-expressions (scale/offset) out
of loops. Run more calculations on double precision data before results
get trimmed to single precision.

Add and extend comments to improve future maintenance. Include (terse)
details of unsupported input data presentations in error messages.

This implementation was neither tuned nor measured for performance.
There still is a lot of redundancy among the branches which handle a
specific input data type. Rephrasing that approach interacts with the
yet to be done performance tuning, thus needs to get addressed later.
The current phrases' verbosity is believed to improve readability.

thus grabbing raw data cannot be done.

Gerhard Sittig 5208214739 input/saleae: improve L2D undersampling, do provide sample data 
The Saleae Logic exported files (Logic2 digital format) don't contain a
samplerate, so users need to specify the value. For values smaller than
the samplerate that was used during the capture undersampling will take
place. An implementation detail of the input module could result in
incorrect timing of sample values in the session feed. In extreme cases
none of the periods between signal edges qualified for submission. In
that case no sample data was sent to the sigrok session at all.

  $ sigrok-cli -i digital_1.bin -I saleae:samplerate=1000

Keep the very timestamp at hand when the last sample data was submitted.
Only advance that timestamp when more sample data was sent. This avoids
the accumulation of timing errors for undersampling scenarios, and does
forward undersampled input data when the user provided sample period has
passed.

This fixes bug #1600.

Gerhard Sittig d2cc60bd45 korad-kaxxxxp: speed up scan process, rephrase response read routine 
The Korad protocol relies on unterminated request and response strings,
which works well enough for fixed length acquisition and status queries.
But the variable length replies to identification requests suffered from
an implementation detail in the receive routine. A large timeout must be
used because supported devices reportedly are slow to respond. There is
no simple yet robust condition to detect the response's completion. The
scan code must prepare for the maximum response length across the set of
supported devices. Unfortunately the maximum amount of time was spent
waiting for the response to occupy the provided response buffer, before
a long total timeout expired.

Rework the korad driver's helper routine which gets a variable length
non-terminated text string. Keep the long initial timeout, and keep
iterating in that initial phase to quickly detect when response data
became available. But terminate the read sequence after a shorter period
without receive data after some initial receive data was seen. Assume
that identification responses get transferred at wire speed and without
additional delays beyond bitrate expectations. Acquisition and status
responses shall not be affected by this change.

This speeds up the scan for devices from roughly 5s to some 0.1s on
newer devices (KA3005P v5.5) and 0.5s on older devices (KA3005P V2.0).

This commit also addresses an issue in the response text termination,
where partial responses contained undefined data. The previous version's
return value was unspecific: Negative for fatal errors, but either zero
or non-zero for successful reads, with no way for callers to learn about
the received amount of data. The rephrased version always returns the
amount of received data, and adds internal documentation which discusses
the implementation's constraints and the motivation for the approach.

This is a modified version of the initial implementation which was

List both vendor names "HAMEG" and "ROHDE&SCHWARZ" in the scpi-pps

vendor names don't support regex matches, so they require individual
profile items. The items also "violate" the alpha sort order in the list
of profiles, but keeping the series' models together is more important.

Add a declaration for the HMP4030 device which re-uses the HMP4040 data
but open codes the smaller channel count. Ideally the .probe_channels()
routine would receive the scpi_pps item as a parameter, and could yield
model specific result data from common information for the series. The
implementation in this commit is the least intrusive approach until
something better becomes available.

This shall cover the whole HMP4000 series:

Unconditionally generate output text when a session packet is received
which carries analog or logic sample data. Even if the data gets queued
and is not shown immediately, in that case the output text remains empty
but needs to be present. Otherwise applications may assume that the CSV
output module had not handled the data at all, which would result in

Gerhard Sittig dc172c38d2 output/ascii: data type nits, rephrase sample bit access 
Use size types for counters, unsigned for bit manipulation. Trigger
position needs to remain a signed int (must be possible to go negative
for "not here", and strictly remains within the output text line length,
so should be good).

Rephrase the nested loop during bit extraction from logic packets, and
how a channel's value at a given sample number gets accessed. Eliminate
redundancy in that spot, to improve readability and simplify maintenance.

Gerhard Sittig 31907b76de output/ascii: style nits in name alignment and trigger flush 
Unobfuscate the implementation of the recent channel name alignment and
trigger position flush, address other style nits of earlier versions:

Don't need a GString for runtime constant channel names (which also
suffered from a mismatch of declaration and allocation). Don't need to
"construct space" when printf(3) can align the value. Pre-allocate text
buffers with more appropriate length when known in advance. Drop another
unused variable. Eliminate data type redundancy in malloc(3) calls. Make
sure to get zeroed memory, disabled channels can result in assignment
gaps. Use consistent brace style and separate variable declaration from
use (no RAII here).

Excess text line length remains, there has been a lot of it in the
previous implementation. It is left for another commit.

Tested with:

  $ sigrok-cli -d demo:analog_channels=0:logic_channels=4 --samples 40 -O ascii -t D3=r -w

Gerhard Sittig d891892dc0 input/saleae: introduce input module for Saleae Logic exported files 
Start the implementation of an input module which covers Saleae Logic's
export files. CSV and VCD are handled by other modules, this one accepts
binary exports for Logic1 digital data (every sample, and when changed),
Logic1 analog data, Logic2 digital data, and Logic2 analog data.

The newer file format versions contain header information and can get
auto-detected, the older formats require a user spec. Some of the file
formats lack essential information in the file content, thus require
another user spec (samplerate for digital data is an example).

The .logicdata file format is unknown, and is not supported. The .sal
format could get added later, but requires local file I/O in the input
module, which current common infrastructure does not provide.

Gerhard Sittig dd8bec71c2 input/vcd: unbreak the logic which skips a user specified period 
Rephrase the default value for the 'skip' option and the detection of a
user specified value. This is tricky because: Sample numbers are kept in
64bit values. Skip and downsample are fed to formulae so we want them
both to be unsigned. Yet absence of a user spec as well as possible user
values 0 and positive must be told apart. Use all-ones for the default
of "-1" which translates to "first timestamp", users need not be able to
specify that negative value.

Make sure to only downsample 'skip' values when the user specified some.
Which avoids the undesired insertion of huge idle gaps at the start of
the capture. An earlier implementation had to check for -1, this recent
version uses an unsigned number in combination with a boolean flag to
achieve this.

Reword some diagnostics messages, and print the samples count between
timestamps while we are here. Add a check for successful text to number
conversion of timestamp values.

How to reproduce:

  $ pulseview -i file.vcd
  $ pulseview -i file.vcd -I vcd:downsample=5
  $ pulseview -i file.vcd -I vcd:skip=111381600

Gerhard Sittig c03aaf342c output/srzip: queue samples before ZIP operation 
Accumulate samples from multiple session feed packets before sending
them off to ZIP archive operations. This improves throughput for those
setups where acquisition devices or input modules provide only few
samples per session feed send call.

This version also splits large packets from applications into smaller
ZIP members (if the application's packet size is larger than the output
module's local buffer size). If that is not desired, the implementation
needs adjustment to immediately pass larger blocks to ZIP operations
(after potentially flushing previously queued data) instead of looping.

This fixes bug #974.

Gerhard Sittig 8c5bd3d9c7 output/vcd: support analog data, more channels, minor cleanup 
Extend and rephrase the VCD output module, to support mixed signal data,
support higher channel counts, and address other minor issues.

Increase the number of VCD identifiers which can get generated. Bump the
limit from 94 to 18346 channels. Prefer single letter names for backwards
compatibility for the first channels. Use two or three letter identifiers
as needed for higher channel counts.

Add support for analog channels, and carefully organize a queue such
that timestamps and their data only get written after input data for
_all_ channels was received from the session feed. Provide IEEE754
double precision values for maximum compatibility with other VCD aware
software, although sigrok internally passes analog data with single
precision. This makes potential later adjustment transparent to external
software.

Factor out and rephrase code while we are here. This implementation
avoids glib calls where they'd hurt performance. A local pool reduces
malloc() pressure to increase throughput. String manipulation is tuned
for simplicity and reduced cost. Special code paths were added to tune
the use cases where mixed signals are not involved (immediate write to
the output text, bypassing the output module's local queue).

An srzip input implementation detail still makes the VCD output consume
lots of memory during merge sort of channels' data. See bug #1566.

Other nits got addressed in bypassing: Adjust data types. Separate the
gathering of detail information and the construction of the VCD header
text to simplify review and future maintenance. Skip VCD identifiers for
disabled channels. Emit a final timestamp to flush the last sample, and
communicate the total capture length.

Gerhard Sittig 0ab36d2f54 input/vcd: rework VCD file import logic (vector, integer, real) 
Extend and rework the VCD input module: accept more data types, improve
usability, fix known issues.

Add support for bit vectors (arbitrary width), multi-bit integer values
(absolute 64bit width limit, internal limitation to single precision),
and floating point numbers ('real' in VCD, single precision in sigrok).
Unfortunately sigrok neither has concepts of multi-bit logic channels
nor IEEE-1364 stdlogic values, the input module maps input data to
strict boolean and multiple logic channels. A vector's channels are
named and grouped to reflect their relation. VCD 'integer' types are
mapped to sigrok analog channels. Add support for scoped signal names,
and the re-use of one VCD signal name for multiple variables.

Rework file and text handling. Only skip pointless UTF-8 BOMs before
file content (not between sections). Handle lack of line termination at
the end of the input file. Process individual lines of input chunks,
avoid glib calls when they'd result in malloc pressure, and severely
degrade performance. Avoid expensive string operations in hot loops.

Rearrange the order of parse steps, to simplify maintenance and review:
end of section, new section, timestamp, data values, unsupported. Flush
previously queued values in the absence of a final timestamp. Unbreak
$comment sections in the data part. Apply stricter checks to input data,
and propagate errors. Avoid silent operation (weak warnings can go
unnoticed) which yields results that are unexpected to users. Unbreak
the combination of 'downsample' with 'skip' and 'compress'. Reduce noise
when users limit the number of channels while the input file contains
more data (keep a list of consciously ignored channels). Do warn or
error out for serious and unexpected conditions.

Address minor issues. Use common support for datafeed submission. Keep
user specified options across file re-load. Fixup data type nits, move
complex code blocks into separate routines. Sort the groups of routines,
put helpers first and concentrate public routines at the bottom. Extend
the builtin help text. Update comments, update the copyright for the
non-trivial changes.

recordings, in all of the meter's modes and including relative, min/max, and
peak submodes. This implementation also parses compare mode (limits check)
responses, although it cannot express the result in terms of the session feed.

Announce the device as a multimeter as well as a thermometer, it supports
up to two probes including difference mode. When in doubt, prefer usability
over feature coverage (the driver side reflects all properties of the meter,
but not all features can get controlled by the driver). The probe routine
requires that users specify the serial port, and enable serial communication
on the meter.

Several TODO items remain. Comments in the driver code discuss limitations
of the current implementation, as well as cases where the meter's features
don't map well to sigrok's internal presentation. This implementation also
contains (optional, off by default) diagnostics for research on the serial
protocol.

Gerhard Sittig 5cc292b34a asix-sigma: discuss usability of data pattern trigger specs 
When data patterns for trigger specs span multiple bits, users may not
want to specify long lists of "<ch>=<lvl>" conditions for sigrok-cli's
--trigger option, and count channels by hand. Or click a dozen dialogs
to specify one data pattern, or modify a previous specification. Setups
with few traces may accept that, "data heavy" setups like parallel data
or address bus inspection may not.

Add comments which discuss the potential use of SR_CONF_TRIGGER_PATTERN.
Outline a syntax which may be flexible enough _and_ acceptable to users,
support data patterns and edge triggers alike, in several presentations
that serve different use cases.  This commit exclusively adds comments,
does not change behaviour.

Update a comment in the user spec to internal format trigger spec parser
to expand on hardware constraints and implementation limitations. Rename
an identifier which checks the number of edge conditions, not the number
of accepted trigger spec details.

Gerhard Sittig e092671365 asix-sigma: unconditionally re-enable trigger support code 
Trigger support became operational again. Drop the compile time switch
which disabled the previously incomplete implementation.

This resolves bug #359.
 2020-05-31 23:56:16 +02:00
Gerhard Sittig f14e6f7e1a asix-sigma: complete and extend capture mode supervision 
Parse trigger specs early when acquisition starts, timeout calculation
needs to reflect on it. Either immediately start an acquisition timeout
for trigger-less configurations. Or prepare a timeout which spans the
post-trigger period, but only start its active period when the trigger
match was detected by the device's hardware.

Extend mode tracking during acquisition to handle other special cases.
Terminate acquisition when the user specified sample count limit exceeds
the hardware capacity, or when no limits were specified and the device's
memory is exhausted.

There is a slight inaccuracy in this approach, but the implementation
fails on the safe side. When both user specified limits and triggers are
involved, then at least the user specified time or sample count span is
provided. Usually more data is sent to the session feed, and all of the
requested period is covered. This is because of the software poll period
and the potential to start the timeout slightly late. As well as having
added some slack for hardware pipelines in the timeout calculation.

Gerhard Sittig debe1ff66d asix-sigma: download sample memory in multiple receive calls 
The previous implementation ran the complete sample memory retrieval
in a single call to the receive callback. Which in combination with
slow USB communication and deep memory could block application logic
for rather long periods of time.

Rephrase the download_capture() routine such that it can spread its
workload across multiple invocations. Run the acquisition stop and
resource allocation for the download, the interpretation of a set of
DRAM lines, and the resource cleanup, as needed. And keep calling the
download routine until completion of the interpretation of the sample
memory region of interest. The workload size per invocation may need
more adjustment.

The previous implementation could stall UI progress for some 20-30s.
This change lets users perceive UI progress while sample memory gets
retrieved and interpreted.

This resolves bug #1005.
 2020-05-31 23:52:24 +02:00
Gerhard Sittig 914f8160e7 asix-sigma: drop obsolete "trigger countdown" in sample interpretation 
Recent commits added "position tracking" for interesting spots in the
sample stream and the current iteration pointer. Which obsoletes the
counters for remaining items until trigger, the "triggered here" flags,
as well as the unfortunate "rewind a little" workaround which lacked a
comment on its motivation or implementation details.
 2020-05-31 23:51:23 +02:00
Gerhard Sittig 8a72362505 asix-sigma: re-enable software check for exact trigger position 
The hardware provided trigger match location is inaccurate. Do check
sample values against the initial trigger condition spec for a short
range of the retrieved sample data, to refine the trigger marker's
position which is sent to the session feed.

Temporarily ignore the optional sample count limit for trigger-using
acquisitions, to reduce the diff size and simplify review. Since the
hardware transparently compresses sample data, we cannot reliably
determine where to start the download and interpretation of sample data,
and the submission to the session feed. Starting early in the sample
memory content, and sticking with the strict sample count limit, could
clip submission before the actual trigger position.

This implementation provides _at least_ the requested amount of data,
and does cover the spot of interest (the trigger position). This, and
the trigger support's having become operational again, is considered an
important improvement. The inaccuracy is considered acceptable for now.
Trigger-less acquisition does enforce the exact sample count limit.
 2020-05-31 23:49:35 +02:00
Gerhard Sittig 66d1790cc0 asix-sigma: rephrase sample memory iteration position and trigger check 
Rephrase how the sample memory iteration position gets tracked, increment
after every event slot already. Update the "last seen sample" status more
often (an event slot can hold several sample items). Arrange for a period
of time where software will check sample data for trigger matches. This
improves the precision of the hardware provided trigger match location.

Do send hardware provided trigger locations to the session feed even if
the software check found no match on the data content. This covers user
initiated button presses (which can unblock the acquisition when the
application provided trigger condition never matches).

Note that this implementation does manage the window of supervision, but
does not yet check the sample values against the trigger condition. This
gets added later.
 2020-05-31 23:46:21 +02:00
Gerhard Sittig 16a5d5ac7d asix-sigma: rework outer sample download loop (DRAM lines iteration) 
Factor USB data transfer out of the code path which interprets sample
memory content. Keep internal state of sample memory download in the
device context. This eliminates local variables, and ideally allows a
future implementation to spread chunked downloads across several read
callbacks, which would improve UI responsiveness.

Update comments while we are here. Address minor portability nits (ull
suffix vs UINT64_C macro). The inner loops (iterating clusters and their
events which contain individual samples) are not affected by this commit.
 2020-05-31 23:45:29 +02:00
Gerhard Sittig 1385f791b0 asix-sigma: more trigger LUT download rephrase, think 16bit entities 
Further rephrase the sigma_write_trigger_lut() routine. It's helpful to
"think" in BE16 quantities to improve readability of LUT address and
parameter downloads. Better matches the vendor's documentation. Also use
a better name for the "trigger select 2" register content.
 2020-05-31 23:44:56 +02:00
Gerhard Sittig ee5cef7103 asix-sigma: concentrate more sample memory interpretation params 
Start moving parameters into the device context which are related to the
interpretation of sample memory content. This can simplify error paths,
allow to release resources late. And ideally sample memory download and
interpretation could spread across several receive callbacks, improving
UI responsiveness. Also makes total and current dimensions available to
deeper nesting levels in the interpretation, which currently don't have
access to these details.
 2020-05-31 23:44:29 +02:00
Gerhard Sittig de4c29fa91 asix-sigma: concentrate parameters for sample memory interpretation 
Create a sub struct in the device context which keeps those parameters
which are related to sample memory interpretation. Which also obsoletes
the 'state' struct and only leaves the 'state' enum as a remainder.

Use the "samples per event" condition instead of the samplerate when
extracting a number of samples from an event's storage. Rename the
de-interleaving routines to better reflect their purpose.
 2020-05-31 23:44:09 +02:00
Gerhard Sittig ea57157d0d asix-sigma: force strict boolen arith in LUT item manipulation 
Mechanically adjust the add_trigger_function() routine to address nits,
attempt to improve maintainability.

Raise awareness of the fact that strict binary arithmetics is done (bit
operators are used), the strict 0..1 set of values needs to be enforced,
and mere "logical truthness" is not good enough in this spot. Explicitly
check for bit positions instead of "shifting out" the bit of interest
and have the 0/1 value result nearly by coincidence.

Extend comments. Group related instructions and separate them from other
groups. Reduce the scope of the rather generic i, j, tmp named variables
which are just too easy to get wrong.
 2020-05-31 23:43:17 +02:00
Gerhard Sittig 3f5f548410 asix-sigma: use more helpers for bit mask creation 
Rename macros to better reflect which of them check a bit position, and
which span a bit field of given width. Adjust more call sites to use the
macros. This takes tedium out of maintenance as well as review. Has the
minor benefit of somewhat shortening text lines, and eliminating nested
parentheses (or getting perceived as if it would).
 2020-05-31 23:42:53 +02:00
Gerhard Sittig 156b6879e9 asix-sigma: rephrase limits management, use sub structure 
Move the acquisition limits related variables into a sub struct within
the device context. Over time they became numerous, and might grow more
in the future.
 2020-05-31 23:42:32 +02:00
Gerhard Sittig fb65ca09b7 asix-sigma: track whether triggers were specified when acquisition started 
There are several separate conditions which the driver needs to tell
apart. There is a compile time switch whether trigger support shall be
built in. There is the condition whether acquisition start involved a
user provided trigger spec. And there is the hardware flag whether a
previously configured trigger condition matched and where its position
is.

Only accept user provided trigger specs when trigger support is builtin.
(The get/set/list availability and spec passing is done in applications
outside of the library, we better check just to make sure.) Only setup
the trigger related hardware parameters when a spec was provided. Only
check for trigger positions when the hardware detected a match.
 2020-05-31 23:41:40 +02:00
Gerhard Sittig 8a57728d0e asix-sigma: enable trigger support code (development HACK) 
Enable the compile time option which builds trigger support code into
the asix-sigma driver. This is a development hack. Trigger support in
the driver is incomplete and currently not operational.
 2020-05-31 23:41:23 +02:00
Gerhard Sittig 3d9373af2e asix-sigma: data type nits, minor variable renames 
Address remaining data type nits. Use more appropriate types for sizes
and counters and indices, as well as for booleans.

Prefer more verbose variable names in a few spots to avoid the rather
generic 'i' symbol, especially in complex code paths with deeply nested
flow control or with long distances between declaration and use. Re-use
an existing buffer in the acquisition start for command sequences which
setup trigger in/out as well as clock parameters.

Introduce some variables which may seem unnecessary. But these are
useful for research during maintenance.

This is a mechanical adjustment, behaviour does not change.
 2020-05-31 23:41:06 +02:00
Gerhard Sittig 53c8a99c41 asix-sigma: prepare configuration re-use across sigrok sessions 
Introduce the required infrastructure to store successfully applied
configuration data in hardware registers. This lets the probe phase of
the next sigrok session pick up where the previous session left. Which
improves usability, and increases performance by eliminating delays in
the acquisition start, by not repeating unnecessary firmware uploads.

The vendor documentation suggests there would be FPGA registers that are
available for application use ("plugin configuration"). Unfortunately
experiments show that registers beyond address 0x0f don't hold the data
which was written to them. As do unused registers in the first page. So
the desirable feature is not operational in this implementation. There
could be different netlist versions which I'm not aware of, or there
could be flaws in this driver implementation. This needs more attention.
 2020-05-31 23:40:19 +02:00
Gerhard Sittig 8bd4dc8799 asix-sigma: nits in the hardware configuration declaration 
Stop assuming that C language variables whould have a specific memory
layout that applications could rely on. Use normal data types in higher
abstraction layers, drop non-portable bit fields. Use existing macros
for the creation of bit masks of a given width.
 2020-05-31 23:39:55 +02:00
Gerhard Sittig 17ed72cc44 sw_limits: start msec timeout period only after start() call 
When application code used the common SW limits API, the call sequence
of init() then set() then check() already kept expiring, which is rather
unexpected. The timeout period should only start when start() is called,
check() should not signal expiration before the start() call.

The specific use case is the combination of an msecs timeout and capture
ratio when triggers are used. The post-trigger period only starts when
the trigger match was seen, even though its length is already known when
the acquisition starts. It's desirable to run the start() call for the
post-trigger timeout late, and not terminate the acquisition before the
trigger match.
 2020-05-31 23:39:28 +02:00
Gerhard Sittig dbb3e2ad3d serial: accept bitrate only serialcomm= spec, default to 8n1 frames 
The previous implementation considered both the UART bitrate and the
frame format mandatory, users had to specify "/8n1" as well just to
change the bitrate.

This commit makes the frame format optional, and defaults to 8n1 which
is so popular these days. When specified, the frame format still needs
to preceed the other optional flow and handshake flags, for maximum
backwards compatibility, and equal robustness in the process of parsing
serialcomm= specs.

Unfortunately device drivers cannot specify their preferred or default
UART frame format. Which means that users still need to provide these
when a device does not use 8n1. This is not a regression, the previous
implementation always needed the frame format spec.

Gerhard Sittig 7718f3ca8f asix-sigma: update comment on channel names (vendor doc says "1-16") 
Eliminate doubt from a comment on ASIX SIGMA's channel names which was
introduced in commit d261dbbfcc. Publicly available documentation does
agree their names start at "1" and go up to "16".
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 2d8a508976 asix-sigma: add support for external clock 
The 50MHz netlist supports the use of an external clock. Any of the 16
channels can use any of its edges to have another sample taken from all
the other pins. It's nice that the hardware does track timestamps, which
results in an exact reproduction of the input signals' timing with 20ns
resolution, although the clock is externally provided and need not have
a fixed rate.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 16791da9c9 asix-sigma: more trigger spec to register values conversion sync with doc 
Rephrase more parts of sigma_build_basic_trigger() to closer match the
vendor documentation. Use the M3Q name. Be explicit about "parameters"
setup (even if that means to assign zero values, comments help there).
Using three BE16 items for the parameters improves readability.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 7dd766e0aa asix-sigma: rephrase trigger LUT creation (mechanical change) 
Rephrase the sigma_build_basic_trigger() and build_lut_entry() routines
to hopefully improve readability. Avoid the use of short and generic
identifiers which are just too easy to confuse with each other and the
1 literal and negation operator in deeply nested loops and complex
expressions that span several text lines. Reduce indentation where
appropriate. Concentrate initialization and use of variables such that
reviewers need less context for verification.

This is a purely mechanical change, the function of triggers remains
untested for now. Setting "selres" in that spot is suspicious, too.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 72ea3b84bd asix-sigma: rephrase trigger LUT upload to hardware for readability 
Rephrase the sigma_write_trigger_lut() routine to work on "a higher
level" of abstraction. Avoid short and most of all generic variable
names. Use identifiers that are closer to the vendor documentation.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 0f017b7da9 asix-sigma: rephrase and extend register access for readability 
Reduce the probability of errors during maintenance, and also increase
readability. Replace open coded nibble extraction and bit positions by
accessor helpers and symbolic identifiers. Adjust existing math where it
did not match the vendor documentation. Always communicate 8bit register
addresses, don't assume that application use remains within a specific
"page". Provide more FPGA register access primitives so that call sites
need not re-invent FPGA command sequence construction. Remove remaining
open coded endianess conversion in DRAM access.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 419f109505 asix-sigma: rephrase firmware dependent param upload at acquisition start 
The 100/200MHz supporting FPGA netlists differ in their register set
from 50MHz netlists. Adjust the parameter download at acquisition start.

Raise awareness of the "TriggerSelect" and "TriggerSelect2" difference
(the former only exists in 50MHz netlists, the latter's meaning differs
between firmware variants). "ClockSelect" semantics also differs between
netlists. Stop sending four bytes to a register that is just one byte
deep, channel selection happened to work by mere coincidence.

Eliminate a few more magic numbers, unobfuscate respective code paths.
Though some questions remain (trigger related, not a blocker for now,
needs to get addressed later).
 2020-05-29 08:06:18 +02:00
Gerhard Sittig abcd477196 asix-sigma: keep remaining samplerate handling in protocol.c 
Make the list of supported samplerates an internal detail of the
protocol.c source file. Have the api.c source file retrieve the list
as well as the currently configured value by means of query routines.

Ideally the current rate could get retrieved from hardware at runtime.
A future driver implementation could do that. This version sticks with
the lowest supported rate, as in the previous version.

Gerhard Sittig a426f74aca asix-sigma: cosmetics, sort protocol.h function groups 
Sort "semi public" routines and "global data" of the asix-sigma driver

maintenance of the driver source.

Gerhard Sittig 7fe1f91f75 asix-sigma: prepare FTDI open/close for "optional open" 
Move all of the FTDI connection handling from api.c to protocol.c, and
prepare "forced" and "optional" open/close. This allows future driver
code to gracefully handle situations where FPGA registers need to get
accessed, while the caller may be inside or outside the "opened" period
of the session. This is motivated by automatic netlist type and sample
rate detection, to avoid the cost of repeated firmware uploads.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 88a5f9eabe asix-sigma: improve error propagation, increase robustness 
Detect more error conditions, and unbreak those code paths where wrong
data was forwarded. It's essential to tell the USB communication layer,
sigrok API error codes, and glib mainloop receive callbacks apart. Since
the compiler won't notice, maintainers have to be extra careful.

Rephrase diagnostics messages. The debug and spew levels are intended
for developers, but the error/warn/info levels will get presented to
users, should read more fluently and speak from the application's POV.
Allow long text lines in source code, to not break string literals which
users will report and developers need to search for (this matches Linux
kernel coding style).

This commit also combines the retrieval of sample memory fill level,
trigger position, and status flags. Since these values span an adjacent
set of FPGA registers. Which reduces USB communication overhead, and
simplifies error handling. The helper routine considers the retrieval
of each of these values as optional from the caller's perspective, to
simplify other use cases (mode check during acquisition, before sample
download after acquisition has stopped).

INIT pin sensing after PROG pin pulsing was reworked, to handle the
technicalities of the FTDI chip and its USB communication and the FTDI
library which is an external dependency of this device driver. Captures
of USB traffic suggest that pin state is communicated at arbitrary times.
 2020-05-29 08:06:18 +02:00
Gerhard Sittig 5c231fc466 asix-sigma: style nits, expression complexity, information locality 
Address minor style nits to improve readability and simplify review. The
sizeof() expressions need not duplicate data type details. Concentrate
the assignment to, update of, and evaluation of variables in closer
proximity to reduce potential for errors during maintenance. Separate
the gathering of input data and the check for their availability from
each other, to simplify expressions and better reflect the logic's flow.

Gerhard Sittig 9334ed6ccd asix-sigma: update copyright notice for recent non-trivial changes 2020-05-29 07:50:33 +02:00
Gerhard Sittig 2a62a9c44e asix-sigma: more u16 sample memory access nits (timestamps, values) 
Further "flatten" the DRAM layout's declaration for sample data. Declare
timestamps and sample data as uint16_t, keep accessing them via endianess
aware conversion routines. Accessing a larger integer in smaller quantities
is perfectly fine, the inverse direction would be problematic.
 2020-05-29 07:50:33 +02:00
Gerhard Sittig a53b8e4d74 asix-sigma: improve robustness of parameter upload to hardware 
Keep application data in its logical presentation in C language struct
fields. Explicitly convert to raw byte streams by means of endianess
aware conversion helpers. Don't assume a specific memory layout for
C language variables any longer. This improves portability, and
reliability of hardware access across compiler versions and build
configurations.

This change also unobfuscates the "disabled channels" arithmetics in
the sample rate dependent logic. Passes read-only pointers to write
routines. Improves buffer size checks. Reduces local buffer size for
DRAM reads. Rewords comments on "decrement then subtract 64" during
trigger/stop position gathering. Unobfuscates access to sample data
after download (timestamps, and values). Covers a few more occurances
of magic numbers for memory organization.

Prefer masks over shift counts for hardware register bit fields, to
improve consistency of the declaration block and code instructions.
Improve maintenability of the LA mode initiation after FPGA netlist
configuration (better match written data and read-back expectation,
eliminate magic literals that are hidden in nibbles).
 2020-05-29 07:50:33 +02:00
Gerhard Sittig 9b4d261fab asix-sigma: style nits, devc in routine signatures, long text lines 
Move the 'devc' parameter to the front in routine signatures for the
remaining locations which were not adjusted yet. Reduce indentation of
continuation lines, especially in long routine signatures. Try to not
break string literals in diagnostics messages, rephrase some of the
messages. Massage complex formulae for the same reason.

Whitespace changes a lot, word positions move on text lines. See a
corresponding whitespace ignoring and/or word diff for the essence of
the change.

Gerhard Sittig b65649f6b9 asix-sigma: reword list of sample rates, (try to) use 1/2/5 steps 
The driver got extended in a previous commit to accept any hardware
supported samplerate in the setter API, although the list call does
suggest a discrete set of rates (a subset of the hardware capabilities).
Update a comment to catch up with the implementation.

Drop the 250kHz item, it's too close to 200kHz. Add a 2MHz item to
achieve a more consistent 1/2/5 sequence in each decade. Unfortunately
50MHz and an integer divider will never result in 20MHz, that's why
25MHz is an exception to this rule (has been before, just "stands out
more perceivably" in this adjusted sequence).
 2020-05-29 07:50:18 +02:00
Gerhard Sittig c749d1ca57 asix-sigma: improve robustness of firmware download, delay and retry 
Running several firmware uploads in quick repetition sometimes failed.
It's essential to stop the active netlist from preventing the FPGA's
getting reconfigured (FTDI to FPGA pins are so few, and shared). Delays
in a single iteration of the initiation sequence improves reliability.
Retries of the sequence are belt and suspenders on top of that.

Before the change, failure to configure was roughly one in ten. After
the change, several thousand reconfigurations passed without failure.
 2020-05-29 07:50:18 +02:00
Gerhard Sittig 80e717b3cf asix-sigma: eliminate magic numbers in firmware file references 
Use symbolic identifiers to select firmware images, which eliminates
magic 0/1/2 position numbers in the list of files, improves readability
and also improves robustness. Move 'devc' to 'ctx' and before other
arguments in routine signatures while we are here.
 2020-05-29 07:50:18 +02:00
Gerhard Sittig 1bb9dc8217 asix-sigma: mark FPGA config phase in "state" of dev context 
FPGA configuration (netlist upload) of ASIX SIGMA devices is rather
special a phase, and deserves its own state in the device context's
"state" tracking. Not only is the logic analyzer not available during
this period, the FTDI cable is also put into bitbanging mode instead
of regular data communication in FIFO mode, and netlist configuration
takes a considerable amount of time (tenths of a second).
 2020-05-29 07:50:18 +02:00
Gerhard Sittig 5e78a56481 asix-sigma: rework time/count limits support, accept more samplerates 
Use common support for SW limits, and untangle the formerly convoluted
logic for sample count or time limits. Accept user provided samplerate
values when the hardware supports them, also those which are not listed.

The previous implementation mapped sample count limits to timeout specs
which depend on the samplerate. The order of applications' calls into
the config set routines is unspecified, the use of one common storage
space led to an arbitrary resulting value for the msecs limit, and loss
of user specified values for read-back.

Separate the input which was specified by applications, from limits
which were derived from this input and determine the acquisition phase's
duration, from sample count limits which apply to sample data download
and session feed submission after the acquisition finished. This allows
to configure the values in any order, to read back previously configured
values, and to run arbitrary numbers of acquisition and download cycles
without losing input specs.

This commit also concentrates all the limits related computation in a
single location at the start of the acquisition. Moves the submission
buffer's count limit container to the device context where the other
limits are kept as well. Renames the samplerate variable, and drops an
aggressive check for supported rates (now uses hardware constraints as
the only condition). Removes an unused variable in the device context.
 2020-05-29 07:50:18 +02:00
Gerhard Sittig 98b43eb3cd asix-sigma: rephrase submission of logic data to session feed 
Introduce a 4MiB session feed submission buffer in the device context.
This reduces the number of API calls and improves performance of srzip
archive creation.

This change also eliminates complex logic which manipulates a previously
created buffer's length and data position, to split the queued data when
a trigger position was involed. The changed implementation results in a
data flow from sample memory to the session feed which feels more natural
during review, and better lends itself to future trigger support code.

Use common SW limits support for the optional sample count limit. Move
'sdi' and 'devc' parameters to the front to match conventions. Reduce
indentation in routine signatures while we are here.

This implementation is prepared to handle trigger positions, but for now
disables the specific logic which checks for trigger condition matches
to improve the trigger marker's resolution. This will get re-enabled in
a later commit.
 2020-05-29 07:50:18 +02:00
Gerhard Sittig 2c33b09255 asix-sigma: eliminate magic numbers in sample memory access 
Add more symbolic identifiers, and rename some of the existing names for
access to SIGMA sample memory. This eliminates magic numbers and reduces
redundancy and potential for errors during maintenance.

This commit also concentrates DRAM layout related declarations in the

Gerhard Sittig dc0906e21c asix-sigma: eliminate magic numbers in FPGA configuration 
Slightly rephrase and comment on the FPGA configuration of the ASIX
SIGMA logic analyzer. Use symbolic pin names to eliminate magic numbers.
Concentrate FPGA related comments in a single spot, tell the Xilinx FPGA
from FTDI cable (uses bitbang mode for slave serial configuration).

This fixes typos in the PROG pulse and INIT check (tests D5 and comments
on D6). Also removes the most probably undesired 100s timeout in the
worst case (100M us, 10K iterations times 10ms delay). Obsoletes labels
for error paths. Drops a few empty lines to keep related instruction
blocks together. Includes other style nits.

Gerhard Sittig 53a939aba5 asix-sigma: rework scan for USB devices, add support for conn= specs 
Stick with the FTDI library for data acquisition, and most of all for
firmware upload (bitbang is needed during FPGA configuration). Removing
this dependency is more complex, and needs to get addressed later.

Re-use common USB support during scan before open, which also allows to
select devices if several of them are connected. Either of "conn=vid.pid"
or "conn=bus.addr" formats are supported and were tested.

This implementation detects and displays SIGMA and SIGMA2 devices. Though
their function is identical, users may want to see the respective device
name. Optionally detect OMEGA devices, too (compile time option, off by
default), though they currently are not supported beyond detection. They
just show up during scans for ASIX logic analyzers, and users may want to
have them listed, too, for awareness.

This implementation also improves robustness when devices get disconnected
between scan and use. The open and close routines now always create the
FTDI contexts after the code has moved out of the scan phase, where common
USB support code is used.

This resolves bug #841.

support suffix notations (units, or scale factors, or multiple separated
numbers in the same text string).

Gerhard Sittig f1833600a0 libsigrok-internal.h: rephrase endianess conversion helpers 
Address style, robustness, and usability nits in the common endianess
conversion helpers in the libsigrok-internal.h header file. Rephrase
preprocessor macros as static inline C language functions to eliminate
side effects, and improve data type safety. Provide macros under the
previous names for backwards compatibility, so that call sites can
migrate to the routines at their discretion (or not at all).

Performance is not affected. Inline routines are identically accessible
to compiler optimizers as preprocessor macros with their text expansion
are. Resulting machine code should be the same.

Introduce variants which also increment the read or write position in
the byte stream after data transfer. This reduces more redundancy at
call sites.
 2020-05-29 06:10:18 +02:00
Gerhard Sittig f2a9a7c2c8 tests: also cover endianess conversion helpers 
Introduce a new tests/conv.c source file which exercises the endianess
conversion macros. It's assumed that some use cases may break their

unreliable operation went unnoticed. This test raises awareness of the
implementation's constraints.

This is a start, the test sequence will benefit from adding some more
cases to increase coverage.

Gerhard Sittig 00f3c94386 uni-t-ut32x: drop redundant close and free at end of scan 
The UT32x driver requires a user spec for the connection. The device
cannot get identified, that's why successful open/close for the port
will suffice. Lack of an input spec as well as failure in the early
scan phase will terminate the scan routine early.

When we reach the end of the scan which creates the device instance
and registers it with the list of found devices, the port already
is closed and the list of devices will never be empty. Remove the
redundant close call and the dead branch which frees the serial port.

Andreas Sandberg 4704f64551 bt/bt_bluez: Implement retry if rfcomm sockets are busy 
There are cases where the connect() call returns EBUSY when trying to
connect to a device. This has been observed when sampling an RDTech
UM24C. In this case, scanning the device works fine. However, when
sampling the device, Sigrok first scans the device, then closes the
connection and re-opens it to sample the device. If the close/open
calls happen in close successions, the Bluetooth stack sometimes
returns EBUSY.

Work around this issue by retrying if the connect() returns EBUSY.

v1ne 1d657f47be modbus: Close device after scan 
Since the device should be closed after the scan, close it in sr_modbus_scan.
Alternatively, every single driver could close the device after calling
sr_modbus_scan. This causes duplicated code, is prone to forgetting it and it
wasn't the calling driver who opened the device in the first place.

Even though the devices/websites/manuals usually say 0..30V, the

simply rotating the knob on the device (and our driver already
reflects that).

The same is true for current, it's usually 0..5A as per docs, but many
(probably all) devices accept 5.1A via serial and knob.

Thus, set the max current of all devices to 5.1A (or 3.1A for 3A
devices). We're assuming they all have this property, and we've seen
this in practice on at least three different versions of the device.

Gerhard Sittig 51e60cde09 input/csv: style nits, drop @brief and DIAG in debug output 
The @brief keyword is not needed since JAVADOC_AUTOBRIEF is enabled in the
Doxygen configuration. Remove a remaining "DIAG" prefix in a debug
message, the output already is filtered according to the log level, and
prefixed by the module name.

Gerhard Sittig 811dcf7ea9 input/csv: re-calculate samplerate after file re-import 
Don't clobber the user provided samplerate (specified by input module
options). This allows to re-determine the samplerate from a potentially
changed file on disk upon reload.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 307b239390 input/csv: expand cleanup (resource release) and unbreak file reload 
The list of previously created channels is kept across file reloads. We
also need to keep (or re-create) the list of channels that are used for
datafeed submission of analog data.

Release more allocated resources in the .cleanup() routine, and do reset
internal state such that a .reset() thus .cleanup() then .receive() call
sequence will work. This code path is taken for re-import of files (see
bug #1241, CSV was affected).
 2019-12-21 18:20:04 +01:00
Gerhard Sittig fbefa03f58 input/csv: improve reliabilty of text line isolation 
Slightly unobfuscate the "end of current input chunk" marker in the data
processing loop. Make the variable's identifier reflect that it's not a
temporary, but instead something worth keeping around until needed again.

Unbreak the calculation of line numbers in those situations where input
chunks (including previously accumulated unprocessed data) happens to
start with a line termination. This covers input files which start with
empty lines, as well as environments with mutli-byte line termination
sequences (CR/LF) and arbitrary distribution of bytes across chunks.

This fixes bug #968.

Accept when there is no line termination in the current input chunk. We
cannot assume that calling applications always provide file content in
large enough chunks to span complete lines. And any arbitrary chunk size
which applications happen to use can get exceeded by input files (e.g.
for generated files with wide data or long comments).
 2019-12-21 18:20:04 +01:00
Gerhard Sittig cb3b80512e input/csv: update developer comments and TODO list 
Mention the required synchronization of default option values and format
match logic in a prominent location where options are discussed.

Update the TODO list for the CSV input module. Mixed signal handling got
fixed by rearranging channel creation. Samplerate can get determined
from timestamp columns already. The double data type for analog data
remains.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 05719d75aa input/csv: move channel creation to after format parsing 
The previous implementation incompletely handled arbitrary data type
oders in mixed signal input files. Rearrange the logic such that all
format specs get parsed first, then all channel creation details get
determined, then all channels get created. It appears to be essential
that all logic channels get created first, resulting in index numbers
starting at 0 and addressing the correct position in bitfields. The
analog channels get created after all logic channels exist. Adjacent
number ranges for channel types also results in more readable logic in
other locations.

This was tested with -I csv:column_formats=t,2a,l,a,x4,a,-,b3 example
data, and works as expected.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig cd7c5f9655 input/csv: add automatic format match support 
Implement .format_match() support in the CSV input module. Simple
multi-column files will automatically load without an "-I csv" spec.
Non-default option values still do require the module selection before
options can get passed to the module.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 43e1e23a11 input/csv: another stab at option help texts 
Try to balance a compact format and completeness/accuracy of content for
builtin help texts for the CSV input module's options. Assume a technical
audience (this is signal analysis software after all).

Rename a few internal identifiers which help organize the list of options
and their help texts. Too short names became obscure.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 7e4e65bf65 input/csv: add support for timestamp columns, auto detect samplerate 
Accept 't' format specs for timestamp columns. Automatically derive the
samplerate from input data when timestamps are available and the user
did not provide a rate. Stick with a simple approach for robustness
since automatic detection is easy to override when it fails. This
feature is mostly about convenience.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig fc3b42e93a input/csv: robustness nits in column format dispatching 
The previous implementation open coded type checks by comparing an enum
value against specific constants. Which was especially ugly since there
are multiple types which all are logic, and future column types neither
get ignored nor have channels associated with them.

Improve readability and robustness by adding helpers which check classes
(ignore, logic, analog) instead of the multitude of -/x/o/b|l/a variants
within the classes.

Also comment on the order of channel creation, and how to improve it.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 08eb955a69 input/csv: update comments/helptext for analog input data 
Expand the developer comment that's inline in the source file. There is
enough room to explain things. Try to come up with a "one-line" help text
that is precise yet compact, and does inform the user of available format
choices including modifiers. Chances are that longer descriptions start
reducing the usefulness of the help or the visibility of options when
users are in a hurry. Those who care can access the manual.

Mark more options as obsolete, and mention more default values in the
builtin help text. Also tweak a comment on getting channel names from
header lines.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 3f1f63f007 input/csv: work around undesired logic/analog group "bleeding" 
Support for mixed signal CSV input data is desirable and should be
possible. The current implementation just happens to not fully cope with
arbitrary mixes of data types in columns yet. Add a quick workaround,
but also a TODO item to properly address the topic later.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig a267bf450c input/csv: accept user provided analog resolution in column formats 
Stick with the (arbitrary) default of 3 digits for analog data. Accept
user specified digit counts in the column_formats= option, like "a4".
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 43bdef2634 input/csv: add support for analog input data 
Extend the CSV input module which was strictly limited to logic data so
far. Add support for analog data types. Implement the 'a' column format,
and feed analog data to the session bus.

This implementation feeds data of individual analog channels to the
session bus in separate packets each. This approach was found to work
most reliably, not all recipients support the submission of multiple
samples for multiple channels in a single packet.

A fixed 'digits' value is used. This needs to get addressed later.

Local experiments suggest that the 'double' data type for analog data
can result in erroneous visual presentation (observed with sigrok-cli).
Use 'float' for now, until the issue is understood and got fixed.
Support for double is prepared internally and is easily enabled.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 5ada72fc0a input/csv: address unassorted nits 
Address several minor nits. Eliminate unneeded variables. Update text to
number conversion comments including wildcard handling. Remove empty
lines in init() which used to spill out a set of lines which all do the
same thing (evaluate a set of options) and shall belong together.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 9e7af34eaf input/csv: move channel creation to column processing details creation 
Move the creation of logic channels to the location where formats fields
get iterated, and column processing details get derived. This reduces a
lot of redundancy, and simplifies the addition of more data formats.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 5a9711764d input/csv: update TODO comments 
Update the list of TODO items at the top of the CSV input module's
source. Text line handling (counting line numbers) got fixed. Adding
support for analog channels was prepared, as are timestamp columns.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 72903e9d55 input/csv: rework user accessible options for consistency 
Rename the CSV input module's option keywords. To better reflect their
purpose, and for consistency across the rather complex set of options
and how they interact. Rearrange the list of options (not that the order
matters from the outside, but it's good to have during maintenance).

Update builtin help texts which will show up in applications, as well as
the source code comments which discuss these options in greater detail.
Would be nice to have a "general" help text for input modules which is
not tied to one single option, to provide an overview or use examples.
Arrange the option keys, short and long help texts such that the source
better reflects the applications' screen layout. To better support
future maintenance, again.

Consistently separate multi-work keywords for improved readability.
Prefer underscores over dashes for consistency with common keys in
shared infrastructure in other project sources (device options, MQ
items, etc).
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 1a920e33fe input/csv: extend column-formats support for backwards compatibility 
Extend the "column-formats" option support in the CSV input module to
also support wildcards and automatic channel count detection. Move the
format string interpretation to the location where the first data line
or the optional header line are seen. Map the simple options (single
column number and channel count, or first column number and optional
channel count) to a format string, to unify internal code paths. Remove
code paths for the previous specific yet limited scenarios.

Rephrase the condition which keeps executing the "initial receive"
phase. The text line termination sequence gets derived from the first
complete text line, but other essential information is only gathered
later, potentially after skipping a large (user specified) amount of
input data. Keep checking for this essential setup data until data or
the header actually were seen, before regular processing of input data
starts.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 2142a79b53 input/csv: introduce column-formats option (flexible logic import) 
Extend the CSV input module, introduce support for the "column-formats="
option. This syntax can express the previous single- and multi-column
semantics, as well as any arbitrary order of to-get-ignored, and single-
and multi-bit columns in several formats.

The previous "simple" keywords for single and multi column modes still
are in place, it's yet to get determined whether to axe them. Depends on
whether users can handle the format strings for these simple cases.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig ef0b9935cf input/csv: fixup input file line number handling 
The previous implementation allowed CSV input files to use any line
termination in either CR only, LF only, or CR/LF format. The first EOL
was searched for and was recorded, but then was not used. Instead any of
CR or LF were considered a line termination. "Raw data processing" still
was correct, but line numbers in diagnostics were way off, and optional
features like skipping first N lines were not effective. Fix that.

Source code inspection suggests the "startline" feature did not work at
all. The user provided number was used in the initial optional search
for the header line (to get signal names) or auto-determination of the
number of columns. But then was not used when the file actually got
processed.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 836fac9cf6 input/csv: unassorted adjustment, mostly "column processing" related 
Reduce "state" in the CSV input module's context. Stick with variables
that are local to routines when knowledge of details need not be global.
Really base the processing of a column's input text on the column's
processing information which was gathered in the setup phase.

Rename few identifiers, to explicitly refer to logic channels (the only
currently supported data type of the CSV input module). Cease feeding
logic data to the session bus when there are no logic channels at all
(currently not really an option). Prepare for simpler dispatching of
parse routines should more data types get added in a future version.

Reduce some "clutter" (overly fragmented stuff that should go together
since it forms logical groups and is not really standalone). Address a
few more minor style nits (sizeof() redundancy, "seemingly inverse"
string comparison phrases).
 2019-12-21 18:20:04 +01:00
Gerhard Sittig f6dcb3200d input/csv: improve "channel name from header line" logic 
Improve the code paths which determine logic channels' names from an
optional CSV file header line. Strip optional quotes from the column's
input text (re-use a SCPI helper routine for that). Also use the channel
name for multi-bit fields, append [0] etc suffixes in that case. Comment
on the manipulation of input data, which is acceptable since that very
data won't get processed another time in another code path.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig e53f32d2b8 input/csv: introduce generic "column processing" support 
Rephrase the CSV input module's implementation such that generic support
to "process a column" becomes available. All columns of an input file's
text line get inspected, a column can either get ignored, or converted
to logic data. A future version can then remove the current limitations
of single- and multi-column modes (either one single multi-bit cell, or
multiple single-bit cells which must be adjacent).

Combine the bin/oct/hex parse routines into one routine which handles up
to four bits per input number digit with common logic. Availability of
more data than channels (according to user specs) is not fatal.

Drop the counter intuitive "first-channel" option, use "first-column"
instead. Warn when comment leader and column separator are identical
(was silent before, may be unexpected). Extend diagnostics and address
minor readability nits, update comments. Rephrase logic channel name
assignment.

Use simple scalar options to derive generic processing details: Either
'single-column' and 'numchannels' are required, with an optional
'format' spec (resulting in single-column mode). Or 'first-column' with
an optional 'numchannels' (multi-column mode with fixed format, using
all available columns by default). The default is multi-column mode with
one logic channel per column and spanning all columns on a text line.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig de8fe3b515 input/csv: improve robustness of "use header for channel names" 
Don't clobber the value of the user provided 'header' option. Use a
separate flag to track whether the header line was seen before, or
needs to get skipped when it passes by.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 246aca5f54 input/csv: move samplerate meta packet to logic data feed submission 
Move the communication of the samplerate meta packet to the very spot
where logic sample data gets sent. This allows to optionally determine
late the samplerate, potentially from input data instead of user specs.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 626c388abf input/csv: rearrange text to logic data conversion and datafeed 
Move the helper routines which arrange for the data feed to an earlier
spot, so that references resolve without forward declarations. Rename
routines to reflect that they deal with logic data.

Slightly unobfuscate column text to logic data conversion, and reduce
redundancy. Move sample data preset to a central location.

Rephrase error messages, provide stronger hints as to why the input text
for a conversion was considered invalid.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig dbc38383b2 input/csv: stricter input data test for multi column mode 
The previous implementation assumed that in multi-column mode each cell
communicates exactly one bit of input (a logic channel). But only the
first character got tested. Tighten the check, to cover the whole input
text. This rejects fully invalid input, as well as increases robustness
since multi-bit input like "100" was mistaken as a value of 1 before.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 19267272d3 input/csv: slightly shuffle text routines, add bin/hex/oct doc 
Add documentation to the bin/hex/oct text parse routines, and move the
bin/hex/oct dispatcher to the location where its invoked routines are.
Stick with a TODO comment for parse_line() to reduce the diff size.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 9eab4435f0 input/csv: unobfuscate text line to column splitting 
The parse_line() routine is rather complex, optionally accepts an upper
limit for the number of columns, but unconditionally assumes a first one
and drops preceeding fields. The rather generic n and k identifiers are
not helpful.

Use the 'seen' and 'taken' names instead which better reflect what's
actually happening. Remove empty lines which used to tear apart groups
of instructions which are strictly related. This organization neither
was helpful during maintenance.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig b2c4dde226 input/csv: trim whitespace after eliminating comments 
Accept when comments are indented, trim the whitespace from text lines
after stripping off the comment. This avoids the processing of lines
which actually are empty, and improves robustness (avoids errors for a
non-fatal situation). Also results in more appropriate diagnostics at
higher log levels.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig c6aa9870b4 input/csv: eliminate magic numbers in options declaration 
The CSV input module has grown so many options, that counting them by
hand became tedious and error prone. Eliminate the magic numbers in the
associated code paths.

This also has the side effect that the set is easy to re-order just by
adjusting the enum, no other code is affected. Help text and default
values is much easier to verify and adjust with the symbolic references.

[ see 'git diff --word-diff' for the essence of the change ]
 2019-12-21 18:20:04 +01:00
Gerhard Sittig ad6a2beec3 input/csv: data type nits (sizes, enums) 
Use size_t for things that get counted: column indices, channel numbers
(line numbers already used size_t). De-anonymize an enum to avoid 'int'
where it gets referenced. Adjust printf(3) format strings. Get unsigned
values from option lookups (stick with 32bits, should be acceptable for
spreadsheet columns and channel counts).

Address other minor nits while we are here: Also terminate the last item
in an enum declaration. Add a doxygen comment for parse_line(). Rename a
parameter to achieve tabular doc text layout.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig e05f18273d input/csv: include section nits 
Rephrase the #include statements in the CSV input module. "config" is
not a system header but is provided by the application source code.
Separate the config and system and application groups (their order is
essential). Alpha-sort the files within their group for simplified
maintenance.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig affaf54012 input/csv: add channel list checks for file re-read 
Do for the CSV input module what commit 08f8421a9e did for VCD. Check
the channel list for consistency across re-imports of the same file.
This addresses the CSV part of bug #1241.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 539188e524 input/csv: improve cleanup code path, unbreak re-import 
The cleanup() routine gets invoked upon shutdown, as well as before
re-importing another file. The cleanup() routine must not release
resources which get allocated in the init() routine, as the init()
routine won't run again in the module's lifetime. The cleanup() routine
must void those context fields which get evaluated in the next receive()
calls.
 2019-12-21 18:20:04 +01:00
Gerhard Sittig 17c30d0593 output/vcd: support smaller timescales with higher resolution 
The previous implementation inspected the input stream's samplerate, and
simply used the next 1kHz/1MHz/1GHz timescale for VCD export. Re-import
of the exported file might suffer from rather high an overhead, where
users might have to downsample the input stream. Also exported data
might use an "odd" timescale which doesn't represent the input stream's
timing well.

Rephrase the samplerate to VCD timescale conversion such that the lowest
frequency is used which satisfies the file format's constraints as well
as provides high enough a resolution to communicate the input stream's
timing with minimal loss. Do limit this scaling support to at most three
orders above the input samplerate, to most appropriately cope with odd
rates.

As a byproduct the rephrased implementation transparently supports rates
above 1GHz. Input streams with no samplerate now result in 1s timescale
instead of the 1ms timescale of the previous implementation.
 2019-12-21 17:19:50 +01:00
Gerhard Sittig 4ddea31451 output/vcd: use larger data type to internally store frequency 
The 'period' member of the VCD output module's context is supposed to
hold frequencies that correspond to the timescale used during export.
An 'int' (in combination with VCD's 1/10/100 constraint) thus would
result in a 1GHz limit, use uint64_t instead to support higher rates.
 2019-12-21 17:19:50 +01:00
Gerhard Sittig 3895064542 output/wavedrom: rephrase accumulation of output data 
Iterate over the received sample set first, before iterating over the
respective sample's number of channels. This avoids redundant extraction
of sampled bits (which saves only little), but also increases locality
of processed data (though string accumulation still may be expensive).

It also adds the future option of RLE compression during accumulation of
output data, which perfectly matches the WaveDrom syntax for repeated
bit patterns.
 2019-12-21 13:58:43 +01:00
Gerhard Sittig 7a0d1bdc20 output/wavedrom: separate data processing logic from init/cleanup 
Rearrange the order of routines in the wavedrom output module. Keep the
flow of .receive() -> .process_logic() -> .wavedrom_render() in one common
group of routines, which is not disrupted by the .init() and .cleanup()
routines which are kind of boilerplate in the source file. This increases
readability and maintainability.
 2019-12-21 13:58:43 +01:00
Gerhard Sittig dd5735c998 output/wavedrom: address style nits 
Adjust brace style, use C language comments, drop camel case. Use size_t

SHOUT in the module's .name property.

Gerhard Sittig dc40081706 asix-sigma: comment on trigger/stop position, silence warning 
Add a comment on the logic which skips the upper 64 bytes of a 512 bytes
chunk in the Asix Sigma's sample memory. Move the initial assignment and
the subsequent update from a value which was retrieved from a hardware
register closer together for awareness during maintenance. Pre-setting a
high position value that will never match when the feature is not in use
is very appropriate.

Adjust the sigma_read_pos() routine to handle triggerpos identically to
stoppos. The test condition's intention is to check whether a decrement
of the position ends up in the meta data section of a chunk. The previous
implementation tested whether a pointer to the position variable ended in
0x1ff when decremented -- which is unrelated to the driver's operation.
It's assumed that no harm was done because the trigger feature is
unsupported (see bug #359).

This silences the compiler warning reported in bug #1411.

Gerhard Sittig ad4174c1d8 ols: introduce metadata quirks support, unbreak Logic Shrimp 
Introduce quirks support for devices which provide incomplete metadata.
Add conservative logic to unbreak the Logic Shrimp. Amend previously
received information when it was incomplete, but don't interfere if a
future firmware version fixes the issue.

Without this change, the device gets detected but "has zero channels"
and would be unusable. Because when a device provides metadata, these
details are used exclusively, no fallbacks apply.

Gerhard Sittig 113de3a572 bt: apply 20s timeout to BLE connect(2) attempts 
Even working BLE devices won't immediately succeed in the first call to
connect(2), which is why the "in progress" phase was added. But absent
peers made the previous implementation try forever, getting stuck in the
sr_bt_connect_ble() call.

Try to balance these two constraints. Do terminate BLE connect attempts
after a generous timeout. When this 20s period passed, there probably is
a configuration error or unresponsive peer. Yet the timeout needs to be
in this ballpark to not erroneously fail for working setups.

Gerhard Sittig b50970a541 lcr/vc4080: introduce LCR packet parser for Voltcraft 4080 (and PeakTech 2165) 
Introduce the lcr/vc4080.c source file which implements the parser for
the serial data stream of the Voltcraft 4080 LCR meter. Add the meter to
the list of supported devices in the serial-lcr driver, as well as the
PeakTech 2165 LCR meter which is another compatible device.

This implementation contains a workaround for USB based serial cables
which seem to suffer from incomplete parity handling (observed with the
FT232R based PeakTech cable). Similar approaches were seen in existing
DMM drivers.

This implementation supports the main and secondary displays. The D and Q
"displays" which are communicated in the serial packets appear unreliable
and redundant, users can have the D and Q values shown in the supported
displays.

Gerhard Sittig 66c300c4a6 serial-lcr: also request packets before initial state retrieval 
Commit cb5cd1538f introduced packet request support in the serial-lcr
device driver. Calls were added to the detection of the device's
presence, and the periodic acquisition of measurement data. Add another
call to the device configuration retrieval that follows the presence
detection, without it communication timed out with no data received.

Also slightly raise the timeout for this device configuration gathering
phase. With one second sharp, the VC4080 was detected, but getting its
current configuration kept failing. This device's serial communication
is extra slow (1200 bps) and the packets are rather large (39 bytes).
Which made the stream detect's receive routine stop checking for the
availability of more data while a packet was being received.

Gerhard Sittig c4d2e6fa5e serial-lcr: move probe, dev inst creation, data read out of scan

improve readability of the serial-lcr driver's probe logic, and reduces
diffs when handling of multiple connections gets added later.

Add a developer comment, the serial-lcr driver needs to handle multiple
connections when the conn= spec is ambiguous (multiple cables of the
same type, with the same VID:PID).

Gerhard Sittig e378e3a2d4 dmm/bm86x: unbreak temperature modes (two probes and no probes) 
The Brymen BM86x supports up to two temperature probes. The dual display
can show individual temperatures of the two probes or differences. The
previous implementation "detected" a value of zero degrees when no probe
was attached and the display showed dash lines. When cycling assignments
of probes to displays, some valid combinations did not result in values
shown by the libsigrok driver.

An implementation detail of the formerly separate brymen-bm86x driver
was lost during recent migration of the dmm/bm86x parser into the
serial-dmm driver. When the meter's temperature function is selected,
it's essential to inspect the primary display's flags and digits, to
determine the secondary display's quantity and unit. Previous versions
never bothered to explicitly check for the "----" digits text, but the
combination of the primary's last digit showing C/F as well as the
binary C/F flags before the value provided hints which the secondary
displays group of digits and flags did not.

This fixes bug #1394.

Gerhard Sittig a1771c26ba serial_hid: make --list-serial output compatible with conn=, print "VID.PID" 
When the list of all connections gets created which are supported by the
HID serial transport, items contain a "hid/ch9325/raw=/dev/hidraw3" path
and a "1a86:e008" pair of vendor and product IDs.

Separate the VID/PID pair by a period not a colon, so that --list-serial
output immediately becomes usable with "--driver <name>:conn=<spec>"
invocations. Eliminate the necessity to adjust clipboard context by the
user. This improves usability in cases where not a single connection
gets addressed, but a group of connections gets specified by ambiguous
conn= specs.

Bug #1390 reports that "!desc" is always true (should be: false?). But

Add a sentinel to the table of supported chips, such that 'desc' becomes
NULL upon mismatch, and the error path is entered.

The serial-dmm entry for Victor DMMs is able to communicate to either

The victor-dmm driver became obsolete and was removed. Rename the

This undoes the essence of commit bf700f679a, which introduced the

device and need not specify the connection. But also resulted in the
UT32x thermometer driver's probe to "succeed" as soon as the WCH CH9325
chip was found, no data check was involved in the scan. Unfortunately
this chip is also used in the popular UT-D04 cable, and thus there were
many false positives.

Gerhard Sittig b800667daf serial-dmm: bm86x: increase packet request frequency 
Request packets from the Brymen BM86x meter much faster. The previous
implementation in the separate driver used to immediately send another
request when a measurement arrived, with a 10ms granularity in the poll
routine, and a 500ms timeout between requests.

Considering the meter's update rate, stick with the 500ms timeout, but
increase the maximum request rate to 10 per second, with a minimum of 2
per second. This receives measurement data at the meter's capability
(compare DC and AC modes, seems to automatically adjust to the internal
operation, and match the display update rate).

Gerhard Sittig 0759e2f55b dmm/bm86x: add Brymen BM86x packet parser, register with serial-dmm 
Move Brymen BM86x specific packet parse logic to a new src/dmm/bm86x.c
source file, and register the routines with the serial-dmm driver's list
of supported devices. Which obsoletes the src/hardware/brymen-bm86x/
hierarchy.

This implementation differs from the previous version: The parse routine
gets called multiple times after one DMM packet was received. Values for
the displays get extracted in separate invocations, the received packet
is considered read-only. Unsupported LCD segment combinations for digits
get logged. Low battery gets logged with higher severity -- the validity
of measurement values is uncertain after all. The parse routine uses
longer identifiers. Packet reception uses whichever serial transport is
available (need no longer be strictly USB HID nor libusb based). All
features of the previous implementation are believed to still be present
in this version.

This configuration queries measurement values each 0.5 seconds and
re-sends a not responded to request after 1.5 seconds. Which follows the
combination of the vendor's suggested flow (frequency) and the previous
implementation's timeout (3x 500ms). This implementation does not try to
re-connect to the HID device for each measurement, and neither checks
for the 4.0 seconds timeout (vendor's suggested flow). Local experiments
work without these.

Some meters which are supported by the serial-dmm driver don't strictly

or even builtin) cable type is used, we can provide a default conn= spec
and thus improve usability. Prepare the DMM_CONN() macro, accept user
overrides.

Gerhard Sittig 09c650d5e9 serial-dmm: fixup 'conn' vs 'serialcomm' confusion 
The 'conn' field in the device context and the CONN values in the

the communication parameters (UART frame format and bitrate), not the
connection (port name). Adjust the respective identifiers.

Also rephrase the evaluation logic. Instead of checking for the absence
of user specs and optionally assigning a fallback value, just preset
from defaults and override from user specs when present. This simplifies
the logic (eliminates a check).

Gerhard Sittig bf5c4d46f8 serial-lcr: move device driver code from src/lcr/ to src/hardware/ 
Keep the ES51919 chip support in the src/lcr/ directory, and move device
driver specific code to the src/hardware/serial-lcr/ directory. Implement
the same driver layout for LCR meters as is used for DMM devices.

This also addresses a few issues in the serial-lcr driver: Unbreak --get
and --show, do process a few LCR packets after probing the device, to
gather current parameter values. Keep sending meta packets when these
parameters change during acquisition, like the previous implementation
did. Use common code for frame/time limits.

Note that although LCR meters usually operate with AC to classify L/C/R
components, one of the officially supported modes is DC resistance.
Which means that an output frequency of 0 is not just a fallback when
packet parsing fails, it's also a regular value of the freq parameter.
List all supported frequencies including DC in strict numerical order.

Although all currently supported devices use the same ES51919 chip, the
implementation is prepared to support other devices which use different
LCR meter chips as well. The list of known equivalent circuit models and
output frequencies is kept in src/lcr/ chip support. It's assumed that
one LCR packet communicates the data for all channels/displays similar
to the serial-dmm driver implementation.

Gerhard Sittig d478724801 serial: add support for optional "RX chunk" callback 
The previous implementation provided a raw input stream of RX data from
read() calls to device drivers. This works great with genuine COM ports,
as well as with most setups which involve simple "cable expanders".

Recent additions of alternative transports (serial over HID and BLE)
added more protocol layers to the setup, and some device drivers are
reported to depend on the very framing of these transports: Mooshimeter
cares about individual BLE notification "frames", and the information
cannot get derived from the payload bytes. Some HID based cables which
obscure the DMM chips' serial protocol, or some HID based setups which
the serial layer does not abstract away as "a cable" may suffer from
similar requirements (do some drivers require access to individual HID
reports? Ikalogic? Victor DMM?).

Add support for an optional "RX chunk callback" which takes precedence
over "mere payload byte streams". Instead of returning payload bytes
from read() calls, the serial layer can call an application defined
routine and pass data bytes in the very framing which the physical
transport happens to use.

It's still up to the implementation of the specific transport whether
the callback approach is supported, and whether the wire's framing is
obeyed or whether payload data keeps getting provided as one raw stream.
It's also implementation dependent whether data reception transparently
occurs in background, or whether callers need to periodically "stimulate"
data reception by calling read or check routines which happen to call
back into the caller should RX data become available.

The approach that got implemented here is not universally applicable,
but serves those specific environments that were identified so far.

resolve ambiguities with multiple cables.

The switch from libusb to hidapi removes a limitation that specifically
was reported for the Mac platform. The serial-over-HID variant should
now work as well. See bug #555.

Drop the background transfers. Stick with a local acquisition stop
routine, because a STOP request needs to get sent to the device. Reduce
the receive buffer size such that either blocking or non-blocking calls
will work. The additional flexibility of the buffer handling and packet
processing does not harm.

which transport to use for subsequent operations (based on port names).

In theory only the transport specific layer depends on the libserialport
library's availability. In this implementation all support for serial
communication still depends on the HAVE_LIBSERIALPORT preprocessor
symbol. This needs to get addressed in later commits.

Gerhard Sittig f0e6b41f7a uni-t-ut32x: rephrase the receive buffer and packets relation 
The previous implementation assumed that a receive data chunk ends
exactly with a sensor packet's end. Yet the buffer had 32 bytes while
the packets have 19 bytes.

Separate the data reception from the packet processing. Collect whatever
chunks the USB connection provides, and scan the resulting buffer for
packets. Cope with either incomplete or corrupt or misaligned packets as
well as with multiple packets in receive chunks. The latter might happen
upon initial synchronization, when a device already sends data or the
serial port buffered previously communicated data.

In the regular case, the computer will process so fast that each single
character will be handled individually. We don't mind. The frequency is
some 60 times per second, and the data volume is 19 bytes. The software
works for the regular case, and synchronizes fast at startup or after
comm errors.
 2019-01-13 19:34:10 +01:00
Gerhard Sittig a0ba75bda2 uni-t-ut32x: improve robustness of packet parser, more diagnostics 
Always print the data bytes of received buffers in the packet parser,
then check some more fixed fields to not process invalid packets, then
process the packet content as the previous implementation did.

Call the packet parser for incomplete packets and discarded input
buffers as well (initial synchronization, re-sync after comm errors).
This results in the availability of more diagnostics during development.

Pass the packet's location and size from outside. This prepares the
logic to cope with situations where the receive buffer contains multiple
(potentially incomplete) packets.

Trigger support needs more attention. User specified triggers either

This implementation is based on protocol information gathered from the
pk2-la project.

Gerhard Sittig 2887799404 scpi-dmm: run OPC queries immediately before essential commands 
The current implementation of the SCPI DMM driver is conservative about
checking the device's being operational, but the *OPC? queries are found
in unfortunate locations. Run the OPC query right before running the
next "actual" command, not afterwards. And certainly not between sending
requests and potentially gathering responses in subsequent calls.

This commit does not change current behaviour, but improves maintenance
before pending commits.

Implement the scpi-dmm driver in such a generic way that it could work
with several protocol variants and with differing models which happen to
use any of these protocol variants. Prepare a list of supported models
with their respective SCPI command set, set of DMM functions and their
precision.

Add support for Agilent 34405A. The ten functions of this device got
tested and are operational, in continuous mode as well as with sample
count or capture time limits. The driver can query the current meter's
function, can change the function, and can run acquisitions in either
the current mode or with a user specified function selection. There is
some potential for improvement: AUTO/MIN/MAX/HOLD indicators are not
supported by this implementation.

Gerhard Sittig e5fa47c1c9 serial: dump DMM packets during stream detection 
Regular operation of serial DMM drivers optionally can dump packet bytes
after the intialization phase has synchronized to the stream. Failure to
synchronize to the stream left developers without a dump, which complicates
research what went wrong.

Do dump packet content while the serial_stream_detect() routine tries to
synchronize to the stream. Use the spew level since the dump occurs upon
every attempt, which translates to: every received byte until a valid
packet was seen (or the synchronization phase expired).

Gerhard Sittig 75aaf967e3 serial-dmm: print data bytes according to specific meter's packet length

Uwe Hermann 00f0016cc3 Consistently use the _WIN32 #define. 
The _WIN32 variant is available pretty much on all compilers, others
might not be. G_OS_WIN32 would probably be an equally well-suited
alternative, but for now we standardize on _WIN32.

The fx2lafw(4) driver supports mere logic analyzers as well as mixed

options. Avoid an error message when channel group device options get
queried, the condition is perfectly legal and non-fatal.

How to reproduce:

Gerhard Sittig 7f5bfd6130 strutil: accept leading whitespace in parse rational 
Programmatic output of floating point numbers might choose to print
spaces instead of an explicit '+' sign, to align the output with the

similar to what humans would have written. Skip leading whitespace
before insisting in seeing either signs or digits or decimals.

Gerhard Sittig 42408643f9 strutil: handle empty fractional in parse rational 
Accept numbers like "123." where the period (dot) is present yet the

popular method of turning an otherwise integer literal into a float.
Compilers and strtod() routines accept this notation, too, so we have to
expect seeing such input.

the errno value for failed conversion attempts (non-zero return codes)
is not too helpful, seeing which text input failed the test is desirable.

lines' layout. Add comments which discuss the motivation of the marker
position's calculation, which differs among each of those modules.

Strictly speaking -O bits was already correct. But I chose to adjust and
comment the logic such that multiple output modules follow a common
pattern. If performance is an issue, the bits.c change might be worth
reverting.

Gerhard Sittig 3c9117094c input/logicport: remove obsolete reset/cleanup assignments

Gerhard Sittig 4c40d096d4 input/logicport: don't re-create channels after input module reset 
Split the creation of channels and groups as well as the creation of the

reset but do not re-create the channels and groups.

This implementation assumes that after reset() of the input module, the
very same set of channels (including their order, names and enabled
state, as well as group membership) results from processing the
subsequently fed file content. Reading rather different configurations
from the same input file by means of repeated reset and re-read may not
work as expected.

Gerhard Sittig a38c2bfbbb input: clear sdi_ready flag and receive() buffer in common code 
Rephrase common input reset logic such that additional common code can
execute after the individual module's reset callback. No behaviour has
changed, the module's reset callback still is optional, and identical
log output gets emitted.

Do clear the sdi_ready flag in the common sr_input_reset() routine, so
that all input modules will parse header information again before
processing sample data when subsequent calls receive new file content.
Void the input module's receive() buffer from common reset code. This
unbreaks the feature of re-reading previously consumed input files.

Extend comments in the common reset and free code paths, which involve
the modules' reset and cleanup routines, which interact in non-trivial
ways. Discuss the responsibilities of common and individual routines, to
remain aware during maintenance.

Gerhard Sittig e8eb24222c input/chronovu_la8: only send data to the session, don't send the header 
The file format is funny, a data part is leading (fixed size) and a

to the session, too, pretending it was part of the data. This change
limits the number of samples that get sent to the session.

converted from do-it-yourself file operations to having intrinsic

Gerhard Sittig 80430d4d20 input/trace32_ad: rephrase the header parse logic 
There were several issues with the previous implementation of the logic
which parses trace32 input files: A string comparison was inverted, and
compared a seven character literal to a five character copy of the input.
One more character was trimmed before CTRL-Z (the CP/M EOF), which often
is SPACE in input files, but might be excessive on other input files.

Replace a DIY character search while we are here. Use symbolic names for
special characters. Factor out a test and memory release, to simplify
error code paths in the remaining logic. Extend comments.
 2018-05-17 22:30:44 +02:00
Gerhard Sittig 8c4bff1d25 input/trace32_ad: silence format match logging, improve robustness 
There is not much point in log messages about format mismatch in the
auto detect phase, where each module gets queried in turn and most are
supposed to not match.

Do not print non-printable characters in log messages. Those could occur
in the format detection phase, or in the regular processing of input
files that either are unexpected or invalid (or is there a binary header
format variant even?).

Gerhard Sittig f54a55da2d input/chronovu_la8: address file size data type nits 
Although the file format handled by this input module appears to be of
fixed size (8MiB plus 5 more bytes), it's more reliable to use a data
type for the file size that is larger than "an int". Although off_t
would be most portable, use uint64_t to match the code which passes the
parameter to the input module.
 2018-05-17 22:25:40 +02:00
Gerhard Sittig 0dabb880af input: pass larger buffer to auto format detection 
The previous implementation already was inconsistent (used to allocate
255 bytes and claimed that 128 bytes were sufficient). While existing
formats already required more than a few bytes of input (regular VCD
files' header sections exceed 255 bytes length).

Increase the buffer size that gets passed to input modules' match
method. Use 4MiB for consistency with other locations. Do not enforce a
minimum size, as there are valid input files which are shorter than 128
bytes. Auto-detection failed on those.

This addresses part of bug #1200.
 2018-05-17 22:25:40 +02:00
Gerhard Sittig 54ee427df0 input: add confidence (detection strength) to format_match() 
When users don't specify the input format, applications can try to have
the format auto-detected. Some of the tests were weak and could result
in false positives.

Add a 'confidence' parameter to the input modules' format_match()
method. Claim high confidence (1) for those formats which can check
magic strings or the presence of essential keywords (vcd, wav). Claim
medium confidence (10) for those formats which happened to mis-detect
inputs in the past (trace32_ad). Claim weak confidence (100) for those
formats which totally lack reliable conditions and rather guess than
detect (chronovu_la8).

Prefer the best match in public scan routines. Return at most one module
to callers even if multiple modules matched, to keep the current API.

This addresses part of bug #1200.

Gerhard Sittig e1b115bd4d input/logicport: introduce input module for LogicPort File (*.lpf) 
Implement an input module for .lpf files, the "LogicPort File" format of
the Intronix LA1034 vendor software. This version supports wires with
enabled and inverted state, compressed samples, signal names, signal
groups (but not multiple assignment), and automatic format detection.

The logic which determines whether "the file header" was completely
received, and sample data can get sent to the session, implements an
assumption in the absence of a better and more reliable condition.

Invalid input gets rejected, but diagnostics is rather limited. Since
all channels get to be the member of a channel group, either specified
by the user in the input file, or arranged for in the input module, the
"missing separator" part of bug 1186 has become obsolete.

sent (the default behaviour of the previous implementation). When a
frame count limit is specified, the respective number of frames gets
sent and acquisition stops.

The fixed amount of 1000 samples per frame is an arbitrary choice. This
compile time option is easily adjusted in the source code.

Andrej Valek e80e1858ef hantek-4032l: Fix structure packing. 
- use pragma to handle different behavior between gcc and minGW bit-field packing
- bit-field integer variables needs to be align to 2-byte boundary
Compiler does not produce an error when accessing into non-__packed pointer.
However, the field might not be properly aligned for this type.

Uwe Hermann 2c267f6819 log: Move log level check so that it affects all handlers. 
Before this change, the loglevel check would only be performed for the
default log handler in libsigrok, but not for other handlers set
via sr_log_callback_set().

This fixes bug #698.

Uwe Hermann 567fe53822 session_driver: Quickfix to prevent looped analog data reads. 
A local buffer was too small, snprintf() was used to write the
name of the analog-1-1-xxx ZIP archive names in that buffer.

Due to the limited size, only 3 characters were usable for the last
number component, i.e. the code would loop around from analog-1-1-999
to analog-1-1-100 (instead of analog-1-1-1000).

As a quickfix, increase the buffer size by a large margin, a nicer
fix should be used later on.

Gerhard Sittig 823b0e29ae output/csv: fix out-of-bounds array access in process_analog() 
Make sure to not exceed the ctx->analog_samples[] array bounds. Don't
use the (huge) channel's index in the device's(!) channel list, instead
use the zero-based and dense index into the array of analog samples in
the accumulation buffer, before writing to the external file.

This fixes the segfault reported in bug #1124.
 2018-03-12 15:55:22 +01:00
Gerhard Sittig a551cb0927 output/csv: use longer names for iteration variables 
The process_analog() logic is rather complex, dealing with the total
list of channels in the device (which can be of different types), and a
number of submitted samples for a specified list of channels. Replace
the rather short variable names for i, j, c (and num_channels) with
something longer that hopefully increases readability of the complex
loop bodies.

Note that this change merely renames identifiers, and does not change
behaviour.
 2018-03-12 15:55:22 +01:00
Gerhard Sittig b078dddb84 output/csv: reduce indentation in process_analog() 
Instead of nesting indentation levels upon equality of a value, skip

Gerhard Sittig 411b2f6822 link-mso19: improve endianess conversion, avoid mem access alignment issue 
Prefer sigrok's endianess conversion helper over the inet htons()

Writing the conversion results in units of bytes also avoids misaligned
memory access. The header length is odd, each payload item got written
as an uint16_t item to an odd address.

Optionally create multiple analog channels in serial-dmm's scan()

analog value from the inspection of a single packet.

Use "large" (4 times 14 bytes) packets for the Metex M-3860M and the
PeakTech 4390A meters, and have those large packets parsed by wrapping
the routines for regular 14-byte Metex packets, and sending four values
to the session bus after reception of one large packet.

Uwe Hermann a9a38e7511 siglent-sds: Replace non-portable strcasestr() with g_strstr_len(). 
The strcasestr() function is non-portable (e.g. not available on
MinGW, possibly elsewhere). Replace it with g_strstr_len() for the time
being. While the latter is not case-insensitive it appears that
that property doesn't matter here ("." should not be relevant anyway,
and e.g. an SDS1202X-E does indeed report "Mpts" as such).

Should it become necessary to have this code be case-insensitive,
we'll have to find a more portable solution than strcasestr().

Surrounding the #include (and later code) with "#if HAVE_RPC" should avoid
these compile errors, but since it's not used at all for now, drop it.

Gerhard Sittig 7a970e3170 usbtmc: only reset Siglent (and Atten) devices in open 
Make the USB reset for USB TMC devices conditional. Check a whitelist,
which in this implementation exclusively contains the Siglent VID.

The whitelist's comment may need adjustment. The VID probably not only
applies to SDS devices, but could be used for SDG and others as well.
And lsusb output suggests the VID is used by Atten, too.

Gerhard Sittig 9a4cc7dd38 usbtmc: add the Siglent VID and reset USB devices in open 
Add the Siglent's VID to a list of blacklisted USB TMC devices.
Unconditionally reset USB devices in the open routine.

This was taken from marchel's development for Siglent SDS. Though the
reset should probably be conditional, and only get applied to devices
which are known to need it.

The comment may need adjustment, maybe individual PID entries are
required. The VID probably not only applies to SDS devices, but could
be used for SDG and other gear as well. And lsusb output suggests the
VID is used by Atten, too.

mhooijboer b33606718c siglent-sds: initial driver implementation for Siglent SDS 
Implement a first version of the driver for the Siglent SDS1000 and
SDS2000 oscilloscopes.

[ gsi: This commit corresponds to git 0228126017e6 of marchelh's tree,
  I adjusted the source to closer match the project's coding style. The
  conversion was verified by this command:

  $ git diff --word-diff=color -w -b <branch>:<dir> <branch>:<dir>

  Changes include: Whitespace adjustment, dead code removal, separation
  of variable declaration and assignment, alpha-sorted includes. Line
  length was not addressed and not every location got adjusted, to keep
  the diff minimal and to reduce effort during review of this version. ]

Gerhard Sittig f396351704 output/srzip: fix potential "use after free" 
The compiler marks a potential use after free, which the current
implementation won't trigger. The error only occurs when a sigrok
channel is neither logic nor analog.

Address the issue nevertheless, to silence the compiler warning, and to
protect against possible programming errors when a future implementation
should support more channel types.

This was reported by clang's scan-build.

Gerhard Sittig 972398f471 output/wav: fixup coding style nits, adjust data types 
Fixup unbalanced braces for more complex if statements, to better
reflect the project's official coding style.

Adjust data types in the float_to_le() routine. A float value gets
copied to a buffer of bytes (uint8_t). Don't use 'char' on the other
side of assignments, to not assume a specific width for char, and to
avoid potential signedness issues. Copy from bytes to bytes instead.

Gerhard Sittig 23eeac46ed output/wav: change default for scale factor from 0.0 to 1.0 
The WAV output module supports an optional 'scale' factor, in its
absence the samples will pass unmodified. The builtin help text is
unexpected, and reads:

  $ sigrok-cli -O wav --show
  ...
  Options:
    scale: Scale values by factor (default 0.0)

Setup a default scale factor of 1.0, which results in identical
behaviour and better reflects what is happening.

Gerhard Sittig aa0979482f output/vcd: assume packed input data image, unbreak 2nd+ channel 
The previous implementation only emitted data for the first enabled
channels, and "saw no changes" after emission of the initial value for
channels on positions that followed a disabled channel.

Assume that the received data from the session bus communicates the bits
of enabled channels in a packed representation. Skip the mapping of
output bit indices to sigrok channel numbers.

This fixes the remaining part of bug #519.

Tested by inspecting in gtkwave the result of command:
  $ sigrok-cli -d demo -C D1,D3,D6 -c samplerate=2M --samples 2500 -O vcd -o trace.vcd

When we find that all input sources (device drivers, and input modules)
provide a dense bit field, all of the mapping logic can get removed
here. This commit just quickly disables the logic.

Gerhard Sittig a299a95413 output/vcd: assign adjacent names to enabled channels 
Identifiers for channels in the VCD header section could be "sparse"
when sigrok channels were disabled. Make sure to not assign names to
disabled channels. This will e.g. assign !, ", and # to channels D1, D3,
and D6, when D0, D2, D4-D5, and D7 are disabled.

This addresses part of bug #519.

Gerhard Sittig 64aa214a22 several DMMs: set DC flag for diode mode 
Few DMM drivers already did it. This commit adjusts the remaining DMM
drivers, to set the "DC" flag for measurements in diode mode.

This fixes bug #144.

Although I don't have the hardware to test, the nature of the change and
the arrangement of driver code suggests it's good. When a meter already
communicated the "DC" status, the change does nothing and won't harm.
The change ensures "DC" is flagged for those meters which previously
didn't, which is desirable.

Gerhard Sittig b8278e0943 strutil: accept trailing whitespace after number text 
Some SCPI based drivers fail to convert response data, because strutil
conversion helpers sr_atol() and sr_atof() don't like trailing spaces
after the number's text that successfully got converted.

It's yet to get determined whether all call sites of the conversion
routines like their eating adjacent whitespace. But given that the
conversion routine explicitly checks for end of the string after the
number, no call site should expect or even depend on trailing text to
keep its whitespace.

See bug #788 for a discussion and example data.

Synchronize sr_parse_sizestring() with sr_si_string_u64() capabilities.
Add support for the T/P/E suffixes. Since this conversion helper deals
with integer values exclusively, there is no issue with case insensitive
matches. The value cannot be pico. Neither is there an ambiguity with
the 10e6 notation.

This addresses bug #763.

Fix a style nit while we are here. Put braces around both arms of a
complex conditional.

Gerhard Sittig 57a88297dd beaglelogic: silence compiler warning 
Explicitly assign NULL to param to avoid the "may be used uninitialized"
warning reported in bug #1094. Behaviour remains unchanged. All references
to the variable were under "if (!conn)", and the assigning arm of the
branch checked for "if (!param)" after assignment. So the error could
not happen, but compilers may not have noticed depending on the width of
their scope during compilation.

Move the initialization of 'conn' closer to the conditional assignment,
such that all paths are seen in one spot during maintenance.

This fixes bug #1094.

Gerhard Sittig e4924d752b motech-lps-30x: fix several compiler warnings 
Check pointers' validity before dereferencing them. Explicitly assign a
default value to variables, before conversion routines conditionally
assign the "real" value (and don't in case of conversion errors). This
avoids processing "garbage" data.

Strictly speaking I cannot see how the conversion routine returns OK and
has _not_ assigned a result. But the explicit assignment won't harm
either, and matches the fallback when the conversion fails (detectibly).
Which means that runtime behaviour won't change.

Gerhard Sittig f9bc17d4c0 input/vcd: fixup VCD timestamp to sigrok samplenum mapping 
When processing of large VCD input files was spread across multiple
parse_contents() invocations, the resulting sigrok stream of sample data
had gaps in them and total timing was off. For instance 74ms of input
data were interpreted as spanning some 600ms or 300ms, depending on the
number of channels in the input stream.

Move the "previous timestamp" variable to the input module context. This
eliminates the inappropriate gaps and fixes the translation of VCD file
timestamps to sigrok sample numbers.

This fixes bug #1075.

As there is a huge range of supported LeCroy scopes, naming

impossible. Hence, it makes more sense to treat all LeCroy
devices as if they were scopes and supported. This approach
lets users try to see how far they get and if they run into
issues, they can then be treated separately - e.g. by creating
a custom device profile.
Unless we do this, the vast majority of LeCroy scopes will
not be recognized by the driver.

Common code unconditionally frees the 'priv' part. The cleanup callback only
shall release descending resources which are local to the callee and opaque
to the caller.

This fixes a double free error. Tested with PeakTech 2170.

Gerhard Sittig dde0175d19 asix-sigma: download sample data upon user initiated stop, too 
When the acquisition was stopped before a configured limit was reached,
no sample data was retrieved. This is because the api.c stop routine did
unregister the receive callback.

Pass the stop request to the receive routine instead when stop is called
while the acquisition is still running. Have sample data downloaded very
much like it's done for reached limits, and existing logic will run the
stop routine again after state was advanced to "idle".

Extend the 'state' tracking while we are here, mark sample download as
well (that was omitted in the previous implementation). Though the
omission was non-fatal. Move the release of 'dram_line' to some earlier
location (as soon as the resource is not needed any longer), before some
rather complex calls to other routines will execute.

Uwe Hermann 8bf18daabb sr_dev_clear(): Always free sdi->priv (devc). 
Until now, clear_helper() callbacks for std_dev_clear_with_callback()
were expected to g_free(devc), but not all of them did that.

Have std_dev_clear_with_callback() unconditionally g_free(sdi->priv)
(i.e., devc), regardless of whether a clear_helper() callback was
provided or not. It was doing g_free(sdi->priv) when no callback
was provided already anyway.

This makes the individual drivers' clear_helper() implementations
shorter and prevents errors such as missing g_free(devc) calls.

This works, because all drivers either call std_dev_clear_with_callback()
directly, or indirectly via std_dev_clear().

This also allows us to remove some no-longer needed dev_clear()
and clear_helper() implementations that only did g_free(devc)
in favor of std_dev_clear().

Uwe Hermann b605edf38f Revert "C++: Avoid std::map::emplace() for GCC 4.7 compatibility" 
This reverts commit 8c52989811.

We now require g++ >= 4.8.1 which supports std::map::emplace(), as does
clang >= 3.3.

Gerhard Sittig 1f4f98e05c asix-sigma: Only open the USB device once (fails with newer libftdi) 
The asix-sigma driver was reported to fail in combination with newer
libftdi versions, because the firmware upload routine opened again an
already opened device, and then failed to claim the interface. Which was
not fatal before with previous libftdi versions.

Remove the redundant open call. Remove the local FTDI context variable,
which brings the firmware upload routine in line with all other calls
that communicate to the USB device.

This fixes bug #471.

Gerhard Sittig ac9534f48a asix-sigma: Only change number of channels after successful firmware upload 
The asix-sigma driver supports different samplerates, which will involve
different firmware images and will affect the number of available logic
channels as well as their memory layout in downloaded sample data.

Make sure to only store the configuration's parameters after the setup
of that configuration has successfully completed, and make sure to store
a consistent set of parameters. Specifically don't change the number of
channels when the firmware upload failed.

This fixes part of bug #471.

Gerhard Sittig 7bcf21683e asix-sigma: Propagate errors from firmware upload 
The firmware upload code paths in the asix-sigma driver used to return
either the SR_OK code, or the magic number 0 for error conditions. Which
happens to be identical and cannot be told apart by callers.

Provide proper SR_ERR return codes for error conditions, such that
callers can tell whether the firmware upload succeeded.

This fixes part of bug #471.

Gerhard Sittig ad466f86cc strutil: Assume bool is true when no value is specified 
Adjust the string to boolean conversion for an edge case. Accept empty
text (either NULL or empty strings) to mean true instead of false.

This behaviour is more useful from the user's point of view, when the
option's name alone will enable a feature, and an explicit "option=yes"
specification is not strictly necessary. All calling applications in
mainline already implemented this semantics.

Gerhard Sittig 61a6d983bd C++ binding: Allow to re-use ConfigKey::parse_string() for Option class 
Split the data type detection from the actual data type conversion in
the ConfigKey::parse_string() method. Allow the Option class to re-use
the public ConfigKey method, to share the maximum amount of data type
conversion code for both Driver and InputFormat option specs.

This is the least intrusive yet most reliable and consistent approach in
the libsigrok C++ binding that allows applications to support driver scan
and input file format options from command line arguments.

Gerhard Sittig 4a465510fb demo: Mask out logic data for disabled channels in datafeed packets 
The previous implementation used to provide datafeed packets which
contain logic data in positions that correspond to disabled channels.

Do mask out logic data of disabled channels in the memory image before
it is sent to the session's datafeed. This implementation works fine for
those situations where either all logic channels are enabled (default
configuration) or when only the upper channels get disabled (which can
be considered a typical use case).

For those configurations where enabled channels follow disabled channels
(i.e. setups with gaps in the sequence of enabled channels) behaviour
will be unexpected: Neither is the mask adjusted to contain gaps, nor
will enabled channels get mapped to result in a dense representation.
The respective code paths are marked with TODO comments.

Add a comment to discuss a non-obvious generator call for analog data in
the acquisition start routine, while we are here.
 2017-06-24 16:33:50 +02:00
Gerhard Sittig 1b7b72d49e demo: Skip generating data when all channels in a group are disabled 
The generator logic determines how many samples per group (analog and
logic) need to get produced, then keeps iterating until each group has
reached the specified count. Different groups can generate different
numbers of samples per iteration, they have their own stride.

It's essential to check whether all channels in a group are disabled, to
then completely skip the respective half of the generation loop. Without
this check, the group would be expected to generate data but it won't,
which results in an endless loop. This was observed with analog channels.

There was another issue with logic channels. Unexpected logic data was
seen in the output although neither logic channel was selected.

This commit fixes bug #923.
 2017-06-23 19:33:24 +02:00
Gerhard Sittig 01f2adb07a demo: Don't generate analog output data for disabled channels 
Skip the emission of session datafeed packets for disabled analog
channels.

Implementation detail: Allow for quick lookup of the channel that is
associated with an analog generator, as the data generation routines
only pass generator references in later calls.

This fixes part of bug #923 (which initially is about unexpected
logic data while analog channels were affected in similar ways).
 2017-06-23 19:33:24 +02:00
Gerhard Sittig d114464551 demo: Only send average result data when averaging is active 
After the requested number of samples was sent, another session df
packet was emitted with one sample for the analog channels, which
contained the most recent result of averaging. Make this emission
depend on the "averaging requested?" flag.

This fixes bug #930.
 2017-06-23 19:33:24 +02:00
Gerhard Sittig d91d0b1250 demo: Unbreak execution with all analog channels disabled 
The 'demo' driver supports scan options to adjust the number of
supported channels, and runtime control for the enabled state of
channels.

Starting with zero analog channels created (scan option) resulted in a
runtime assertion. Creating but disabling analog channels (GUI checkbox,
CLI option) resulted in unexpected output for disabled channels.

Move the creation of a hash table out of the conditional loop that
iterates over created analog channels. Which results in the table's
always being valid, and iteration during data acquisition yields no
analog output as is expected.

This fixes bug #625.
 2017-06-23 19:33:24 +02:00
Gerhard Sittig f1c79a6a35 demo: Drop previous "default enabled" logic (experiment remainder) 
A previous implementation of the demo driver supported the creation of
larger channel counts yet only enabling part of them by default. This
was kind of pointless, I just was not aware of the available scan
options.

Drop the "enabled channels" limitation, enable all channels that get
created (like the implementation before the experiment did), and create
as many channels as was compiled in by default or later got specified
by scan options.

JTAGulator
----------
The Grand Idea Studio JTAGulator also implements the SUMP protocol and
thus is covered by the OLS driver. See the vendor's wiki on details how
to enable the Logic Analyzer mode of operation.
https://github.com/grandideastudio/jtagulator/wiki/Logic-Analyzer
Mooshimeter
-----------
The Mooshim Engineering Mooshimeter is controlled via Bluetooth Low Energy
(sometimes called Bluetooth 4.0), as such it requires a supported Bluetooth
interface available. The 'conn' option is required and must contain the
Bluetooth MAC address of the meter.
Example:
$ sigrok-cli --driver mooshimeter-dmm:conn=12-34-56-78-9A-BC ...
Since the Mooshimeter has no physical interface on the meter itself, the
channel configuration is set with the 'channel_config' option. The format
of this option is 'CH1,CH2' where each channel configuration has the form
'MODE:RANGE:ANALYSIS', with later parts being optional. In addition for
CLI compatibility, the ',' in the channels can also be a '/' and the ':' in
the individual configuration can be a ';'.
Available channel 1 modes:
- Current, A: Current in amps
- Temperature, T, K: Internal meter temperature in Kelvin
- Resistance, Ohm, W: Resistance in ohms
- Diode, D: Diode voltage
- Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max)
Available channel 2 modes:
- Voltage, V: Voltage
- Temperature, T, K: Internal meter temperature in Kelvin
- Resistance, Ohm, W: Resistance in ohms
- Diode, D: Diode voltage
- Aux, LV: Auxiliary (W input) low voltage sensor (1.2V max)
Only one channel can use the shared inputs at a time (e.g. if CH1 is measuring
resistance, CH2 cannot measure low voltage). Temperature is excepted from
this, so the meter can measure internal temperature and low voltage at the
same time.
Additionally, the meter can calculate the real power of both channels. This
generally only makes sense when CH1 is set to current and CH2 is set to a
voltage and so it is disabled by default. It must be enabled by enabling the
'P' channel (the third channel).
The range of the channel specification sets the maximum input for that channel
and is rounded up to the next value the meter itself supports. For example,
specifying 50 for the voltage will result in the actual maximum of 60.
Specifying 61 would result in 600. If omitted, sigrok will perform
auto-ranging of the channel by selecting the next greater value than the
latest maximum.
The analysis option sets how the meter reports its internal sampling buffer
to sigrok:
- Mean, DC: The default is a simple arithmetic mean of the sample buffer
- RMS, AC: The root mean square of the sample buffer
- Buf, Buffer, Samples: Report the entire sample buffer to sigrok. This
results in packets that contain all the samples in the buffer instead
of a single output value.
The size of the sample buffer is set with the 'avg_samples' option, while
the sampling rate is set with the 'samplerate' option. So the update rate
is avg_samples/samplerate. Both are rounded up to the next supported value
by the meter.
Example:
$ sigrok-cli -c channel_config="Aux;0.1/T" --driver mooshimeter-dmm...
$ sigrok-cli -c channel_config="A;;AC/V;;AC" --driver mooshimeter-dmm...

* Protocol parser for Brymen BM850s DMM packets. The USB protocol (for the
* cable) and the packet description (for the meter) were retrieved from:
* http://brymen.com/product-html/Download2.html
* http://brymen.com/product-html/PD02BM850s_protocolDL.html
* http://brymen.com/product-html/images/DownloadList/ProtocolList/BM850-BM850a-BM850s_List/BM850-BM850a-BM850s-500000-count-DMM-protocol-BC85X-BC85Xa.zip
*
* Implementor's notes on the protocol:
* - The BM85x devices require a low RTS pulse after COM port open and
* before communication of requests and responses. The vendor doc
* recommends 100ms pulse width including delays around it. Without
* that RTS pulse the meter won't respond to requests.
* - The request has a three byte header (DLE, STX, command code), two
* bytes command arguments, and three bytes tail (checksum, DLE, ETX).
* The checksum spans the area (including) the command code and args.
* The checksum value is the XOR across all payload bytes. Exclusively
* command 0x00 is used (initiate next measurement response) which does
* not need arguments (passes all-zero values).
* - The response has a four byte header (DLE, STX, command code, payload
* size), the respective number of payload data bytes, and a three byte
* tail (checksum, DLE, ETX). The checksum spans the range after the
* length field and before the checksum field. Command 0 response data
* payload consists of a four byte flags field and a text field for
* measurement values (floating point with exponent in ASCII).
* - Special cases of response data:
* - The text field which carries the measurement value also contains
* whitespace which may break simple text to number conversion. Like
* 10 02 00 0f 07 00 00 00 20 30 2e 30 30 33 32 20 45 2b 30 46 10 03
* which translates to: 07 00 00 00 " 0.0032 E+0". Text for overload
* conditions can be shorter which results in variable packet length.
* Some meter functions provide unexpected text for their values.
* - The reference impedance for decibel measurements looks wrong and
* requires special treatment to isolate the 4..1200R value:
* bfunc 80 20 00 00, text " 0. 800 E+1" (reference, 800R)
* The decibel measurement values use an unexpected scale.
* bfunc 00 20 00 00, text "-0.3702 E-1" (measurement, -37.02dBm)
* The reference value gets sent (sometimes) in a DMM response when
* the meter's function is entered, or the reference value changes.
* The 'bfunc' flags combination allows telling packet types apart.
* - Temperature measurements put the C/F unit between the mantissa
* and the exponent, which needs to get removed: " 0.0217CE+3"
* - Diode measurements appear to exclusively provide the 'Volt' flag
* but no 'Diode' flag. The display shows ".diod" for a moment but
* this information is no longer available when voltage measurements
* are seen.
