Bert Vermeulen f0de2dd0fa Remove SR_CONF_MAX_UNCOMPRESSED_SAMPLES again.
The maximum sample size that can be set on a device is now published
by sr_config_list(SR_CONF_LIMIT_SAMPLES). This returns a tuple of
uint64_t representing minimum and maximum number of samples.

Daniel Elstner 9497f49ef8 sysclk-lwla: Improve message log output.
Report settings at acquisition start as informational messages.
Print a message when the the trigger condition has been met.
Demote some other messages from information to debug, and use
the %zu format for printing size_t values.

Daniel Elstner 2cfd16a316 sysclk-lwla: Streamline packet output logic.
(process_sample_data): When expanding run-length samples into
session packets, calculate the number of samples to write in
advance while honoring all constraints.  This is cleaner than
checking constraints within the expansion loop.  Also, the new
logic always fills up packets exactly to whatever limit applies
first, thereby removing the need for truncation after the fact.

Daniel Elstner 29d587670d sysclk-lwla: Implement SR_CONF_LIMIT_MSEC.
Allow the acquisition to be constrained by time in addition to
a sample count limit.  Since the LWLA protocol actually provides
only a duration natively, implement the sample count limit on top
of the new duration limit.

With this change, limiting an acquisition in external clock mode
should finally work properly.

poljar (Damir Jelić) 091c962127 demo: Add triangle pattern. 2014-01-17 14:30:28 +01:00
poljar (Damir Jelić) 4374219bc8 demo: Implement sine wave pattern.
This adds sine wave generation capabilities for the analog channels in the demo
driver. The frequency of the sine wave depends on the configured sample rate of
the demo device. The frequency of the sine wave is always 20 times smaller than
the sample rate, in other words we always have 20 samples per period.

poljar (Damir Jelić) c06c24d2d3 hameg-hmo: Silence warning about format security.
The command for fetching the sample rate while in single shot mode doesn't take
an argument so the snprintf here is redundant.

poljar (Damir Jelić) 23e1ea7a7d hameg-hmo: Update the sample rate when the channel states or the timebase change.
The sample rate on the Hameg scopes changes depending on the number of channels
turned on and on the current timebase.

Update the sample rate if any of the above change.

poljar (Damir Jelić) 8de2dc3b2e hameg-hmo: Change the way vdiv and timebase are saved.
The current vertical division setting (per channel) and the timebase are stored
as a floating point number. This is suboptimal since clients expect us to send
this information to them in form of a rational number.

Store only the index of the current setting since all the supported settings are
already stored inside of an array.

poljar (Damir Jelić) 66e3219dbd hameg-hmo: Send the DF_END packet in acquisition_stop()
The DF_END packet was send out after all configured frames were fetched, but
devices may stop the acquisition at any point in time and an DF_END will not be
send out in this case.

Send the DF_END packet inside of acquisition_stop() so this can't happen.

poljar (Damir Jelić) 68e3d07014 hameg-hmo: Close the device after initial scan.
The device is after a scan left open and clients that don't call unconditionally
dev_open() will never fetch the initial device state.

Close the device after the scan so clients know they need to open it.

poljar (Damir Jelić) 9806c2d573 strutil: Add function to parse floating point numbers while ignoring the locale.
Most of the supported gear uses the ANSI C locale for communication, and if the
client sets up an incompatible locale parsing would fail.

This function ignores the client's locale and parses floating point numbers
using the ANSI C locale. This function should be always used when parsing
floating point numbers coming from the instrument.

poljar (Damir Jelić) 92b68bb5d6 device: Pass sdi as an function argument to config_list in dev_has_option()
With drivers that support multiple devices we need to know the device model
while listing options. That information is most of the time saved in the private
part of the dev_inst structure.

Pass the pointer to the dev_inst structure as an function argument so we have
access to this information.

poljar (Damir Jelić) 580f309948 strutil: Correctly parse floating point frequencies in parse_size_string().
parse_size_string() incorrectly parses a real number, e.g. 1.5 kHz ends up
being 1Hz.

This patch fixes parse_size_string() to take the fractional part as well into
account. The fractional part is parsed as an double precision floating point
number while ignoring the locale.

Daniel Elstner 0b92c32cb8 sysclk-lwla: Make use of the probe index again.

so use it instead of relying on the list order.

Daniel Elstner d02d475442 sysclk-lwla: Bypass divider in external clock mode.
(lwla_setup_acquisition): Set the clock divider bypass
flag to 1 for the external clock modes as well.

external clock source is selected.

Daniel Elstner 313c7a7da2 sysclk-lwla: Utility functions clean-up and semantic fixes.
(lwla_send_bitstream): Unref the mapped file earlier in order
to simplify the error handling.
(lwla_receive_reply): Do not treat a reply buffer length of
zero as silent no-op.  That logic was left over from an earlier
iteration, before the distinction between reply buffer size and
expected read length was introduced.

Daniel Elstner 945e4343e2 sysclk-lwla: Avoid warning due to bogus range check.
(lwla_set_clock_source): Checking whether an enum value is greater
than or equal to zero apparently results in a warning with some
compilers.  Assign the enum to an unsigned variable to avoid this,
and return SR_ERR_BUG if the range is exceeded, as this indicates
a bug in the driver code itself.
