Note: this is not ready for merging; there are issues with the firmware on
the device that are awaiting an update from the manufacturer. However, I've
done what I could, so I figured I'd get a head start on submitting it by
putting it online for an early review. Sources are at
https://github.com/mwm/libsigrok.
And I have questions:
1) The DSO has three modes: Auto, Norm and Single. At least two of those
are standard for DSOs, but I don't see any sign of them being supported. Am
I missing something? For now, I've used the continuous option to set it to
AUTO or SINGLE.
2) The SR_CONF_HORIZ_TRIGGERPOS is weird on this, as instead of being an
arbitrary variable, it takes on list of settings (probably a UI limitation
more than anything else). I've added it as an _LIST configuration option,
but neither sigrok-cli nor pulseview seems to deal with that. Is this just
not supported, and requires fixing them? Or is there something I can do in
the driver to make it work?
3) It can report a number of measured quantities (Vrms, Vpp, Vavg, Vmin,
Vmax, freq) and I se an SR_CONF_MEASURED_QUANTITY, but it's only used by an
HP scope. It's not clear that reporting those is useful, since they can be
worked out in the client, but if they are, how would I connect them?
4) There are a number of sample modes - frame counts, sample counts, time -
that seem like they would also be dealt with in the client instead of the
hardware, but that doesn't seem likely. But without one of those - or
continuous - it's not clear how I'd go about capturing values with
sigrok-cli. Is there an explanation.
5) While I get values from sigrok-cli, I can't seem to find anything in
pulseview. Is there a tutorial somewhere on using it with a DSO? I've found
lots of using with a logic analyzer, but none for using a 'scope.
