Bert Vermeulen ac136b574a Add new software trigger as a library-wide facility. 
This is strictly an internal feature, for use by drivers for hardware
that doesn't have its own trigger mechanism.
 2014-05-28 15:53:27 +02:00
Bert Vermeulen 7b5e6d2978 Add new triggering framework. 
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.

Uwe Hermann 144f6660d0 Don't define names ending with _t (POSIX reserved). 
Avoid defining any names ending in _t, those are generally reserved
for POSIX usage. For details see:

Daniel Elstner 2a854d7139 hwdriver: Introduce sr_config_commit() API call.

drivers to be notified upon changes to probe settings.

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.

poljar (Damir Jelić) c09392d092 scpi: Add CMD_GET_SAMPLE_RATE to the command enum. 2014-01-16 16:27:35 +01:00
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.
