Only the capabilities which map directly to SCPI commands supported by
sigrok are implemented at this time. This is sufficient to control
the most often used functionality of this AC source
Some devices with more than one microcontroller report the firmware
version for each of them, giving us more than four tokens. When that
happens, sigrok aborts, even though it received a valid response.
This happens, for example with the Chroma 61604:
'Chroma ATE,61604,001060,1.25,1.34,1.20'
With gcc 5.1 released and defaulting to std=gnu11, the code will be compiled
according to different standards depending on the compiler version so we
should better specify explicitly what standard we are targetting.
C11 is now quite mature, it is supported in the just release Debian stable
(gcc 4.9) and also in old-stable (gcc 4.7), so there should be no reason to
use anything more ancient.
We also should have no reason to need any non-standard GNU extension.
So using only C11 + POSIX sounds like the best option right now.
isascii() is a superset of isalpha() and isblank() so the current
code doesn't really make sense.
Moreover, isascii(x) is just a funky and non standard way to
write x < 128.

Check the return value of sr_gpio_setval_export() in bl_acme_set_power_off()
and return an appropriate error if the call fails.

This reverts commit 4cd97e5ad7.
We should actually check the return value of sr_gpio_setval_export().

Both ina2xx and tmp401 linux drivers used by baylibre-acme expose
the standard hwmon update_interval attribute, which affects the internal
update interval of the chip.
When setting samplerate for data acquisition try to modify this
attribute accordingly.

PROBE_FACTOR and POWER_OFF options are advertised for all ACME probes
(channel groups) regardless of whether they actually have given capability.
Check these options in config_list() at runtime and only advertise them
for probes which support them.

For Windows builds (which require MinGW-w64) we currently support:
- cross-builds using MXE (mxe.cc) and possibly other cross-compile setups
- native builds using MSYS2 (sf.net/projects/msys2/)
Neither of those require explicitly specifying ACLOCAL_DIR.
This requires sr_hw_cleanup_all() and sanity_check_all_drivers()
to also take a context.
The (runtime) generation of the driver list now happens in sr_init()
and sr_driver_list() always returns that pre-generated list. This fixes
a segfault when (correctly) invoking multiple sr_init() and sr_exit()
calls with different contexts (caught by the unit tests).
This fixes bug #565.
We should have been doing this all along, but we get away with it
on Linux where libusb can do everything with fds, and we get away
with it for many drivers that have a short timeout on their events.
On Windows though, handling this correctly is essential.
Fixes bug #343.
This temporarily reverts commit 421bc3eba0.
We cannot yet use the sr_config_*() wrappers, otherwise loading *.sr
files is broken. A fix is being worked on.
This is a partial fix for bug #343, which lead to a large amount of
handles being created, and eventually to a frontend "hang".
It's not yet a "full" fix as some issues are still observable,
but it successfully improves the situation on Windows to the extent
that frontend hangs due to large amounts of handles no longer seem
to happen.
Thanks to Boris Gjenero <boris.gjenero@gmail.com> for the debugging
efforts, testing, and updating of this patch!
Additionally, this seems to also fix a "SysClk LWLA hanging" bug
and apparently not receiving any samples during an acquisition
(tested on an LWLA1034).
This closes bug #328.
