The driver should now be able to cope with e.g. multiple ChronoVu LA8
and/or ChronoVu LA16 devices being connected to the same PC.
It now also provides the serial number and connection ID, which can be
used by frontends to differentiate multiple devices.
Also improve the scanopts / drvopts / devopts lists handling.
This fixes bug #504.
With the current driver API and the corresponding session event
handling, it is not possible to destroy and then re-create an
event source with the same key within the same main loop iteration.
The next generation driver API will fix this problem. But for now,
just change the driver to make do without that sort of thing. Also
increase the I/O timeout to 100 ms to be safer in the event of all
kind of delays the OS environment may induce.
This fixes bug #678.
Evaluate all 64 bit of the duration field in the capture status
record. Although unlikely in practical use, due to compression
it is possible for the duration in ms to exceed 32 bit.
zip_discard() was introduced in libzip 0.11, which some systems
do not have yet. Provide a fallback replacement for zip_discard(),
and reduce the requirement to libzip 0.10 again.
This fixes bug #674.
During initialization of the LWLA1034, read the 64-bit test word
twice and verify the result of the second read only. This better
matches what the original vendor software does.
Apparently, these four registers form an interface for indirect
access to another internal 64 bit wide memory. This is likely the
same memory as that accessed by the bulk transfer commands 7 and 8.
Added support for SR_CONF_REGULATION which returns value for CH1
Also VELLEMAN LABPS3005D (only device currently supported) sends single
'M' character in beginning of return value, which is specially discarded.
Trying to configure an invalid capture ratio would reset the
previously configured value. Instead, we should just reject the
new value and keep the original one.
Introduce a new API function sr_session_stopped_callback_set()
which can be used to receive notification when a session stops
running. This allows applications to integrate libsigrok event
processing with their own main loop, instead of blocking in
sr_session_run().
With this driver it is possible to set voltage target and current
limit. Also enabling and disabling the output is possible.
Analog output sends read back values from output. If output is
disabled analog outputs 0.00.
In protocol.c there is a g_usleep() call. This gives almost
every time enough time for PSU to parse and process input.
Multichannel devices aren't supported.
