The new triggers consist of a set of structs and an API to manipulate
them. Both logic and analog triggers are supported, in an unlimited
number of stages.
A single struct sr_trigger containing its stages and triggers is then
added to the session.
In case of a driver where the hardware supports triggering, the struct
is then converted and used to arm the hardware trigger. Drivers without
hardware trigger support, such as fx2lafw or multimeter drivers, use it
as the basis for a software-based trigger implementation instead.
The name 'probe' (and thus 'probe group') is a relic from the times when
sigrok was mostly about logic analyzers. Nowadays we support a lot more
device types where 'probe' is not really a good term and 'channel' is
much better suited.
This fixes parts of bug #259.
(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.
This allows a frontend to initialize a session file, providing the
required samplerate and probe names, without having a proper
struct sr_dev_inst handy.
sr_session_append() is then used to add captured data to the session
file, as usual.
The existing sr_session_save() function works the same way as always.
This patch adds helper functions for converting a string to different number
formats (double, long, float, int).
These functions are exposed in the public API.
This extends the session file format to contain logic data files named
either "logic-1" as before, or "logic-1-1", "logic-1-2", ...
representing chronologically ordered chunks of captured data.
The chunks are transparently concatenated together by sr_session_load().
sr_config_get() provides a GVariant owned by the caller, so it must be
released with g_variant_unref() when done.
sr_config_set() takes a GVariant from the caller which may be floating;
it will be properly sunk and release after use by this function. Thus
the output of g_variant_new_*() may be used as an argument.
sr_config_list() also provides a GVariant owned by the caller, to be
unreferenced when done.
sr_config_make() can take a floating reference.
This has been deprecated in favor of sr_session_stop() since a while.
None of the current frontends use sr_session_halt() anymore, neither
does libsigrok.
This takes an sr_config key and returns a list of possible values for
that key to be submitted with config_set(). The format of the list and
its contents is dependent on the key.
This will replace the SR_DI_* keys that returned such a list before,
such as SR_DI_SAMPLERATES.
This patch marks packet structures and their payloads as const.
This indicates to packet receivers that modifications to these are
not allowed. In general all pointers should be marked const unless
modification of the referenced data is explicitly allowed.
These are used to list the device instances currently known to the driver,
and clear that list.
Drivers that don't necessarily clear their list of instances on every scan,
such as genericdmm, need to provide these to the frontend to keep instance
management sane.
