Uwe Hermann 374b0a94b2 output/analog: Fix a compiler warning on Mac OS X.
Apparently PRIu64 and G_GUINT64_FORMAT differ on some systems for
unknown reasons. Use G_GUINT64_FORMAT to get rid of the warning
for now.

Gerhard Sittig 556a926d43 serial-dmm, metex14: add support for multiple channels per DMM
Optionally create multiple analog channels in serial-dmm's scan()
routine. Allow the meters' parse routines to fill in more than one
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.

Thanks to Frank Stettner <frank-stettner@gmx.net> for testing and
fixing the initial implementation of this extension.

Gerhard Sittig 51e1f5661c serial-dmm: style nit (init vs assign, memmove(3))

Uwe Hermann d18bf7bdfc std.c: Add missing <sys/time.h> #include and _XOPEN_SOURCE.

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().

Uwe Hermann 04fe775be6 siglent-sds: Drop currently unused <rpc/rpc.h> #include.
This causes some compile errors on platforms where RPC is not available, e.g.

  siglent-sds/api.c:25:21: fatal error: rpc/rpc.h: No such file or directory

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 563c246329 README.devices: add Siglent SDS to the firmware and conn= sections 2018-02-12 00:13:49 +01:00
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 ca25a3ee0b README.devices: discuss conn= and USB/TCP/VXI in addition to RS232
The conn= specification is not strictly related to RS232 communication.
Provide examples for other USB specs (as they are used for some DMM and
LCR drivers), as well as TCP and VXI (which are often found with MSO
drivers).

Gerhard Sittig eac9fcd268 hameg-hmo: fix potential NULL dereference

Gerhard Sittig addbb09bf8 hameg-hmo: fix potential memory leak
Make sure to release the allocated "pod enabled" memory, too, when SCPI
communication during channel setup fails. Defer the return with an error
(instead of duplicating the free() invocation).

This was reported by clang's scan-build.

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.

Gerhard Sittig 751ba4c8ed strutil: support tera/peta/exa suffixes in symbolic size specs
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.
