This change moves the handling of series differences out to the points in the
code where they actually matter, unifying the overall structure of the code.
It also adds new VS5000/DS1000 series equivalents for commands that were
previously only implemented on the later models.
After this change, trigger waiting and the 'Memory' data source are supported
on the VS5000/DS1000 series.
(sr_session_start): Just before starting acquisition on
a device, call sr_config_commit() to apply pending config
changes to the hardware device.
(sr_session_dev_add): Ditto. Also, return an error code
if starting acquisition failed.
(sr_dev_driver.config_probe_set): New optional callback enabling
drivers to be notified upon changes to probe settings.
(sr_dev_probe_enable, sr_dev_trigger_set): Invoke new driver
callback on changes.
(sr_dev_driver.config_commit): New optional callback allowing
drivers to defer application of configuration settings until
an explicit call to config_commit().
(sr_config_commit): New public wrapper function.
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.
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.
(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.
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.
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.
