Soeren,
Ok, lets try replying to the correct message....
Once again, thanks for clarifying that. It explains then why only one
frame is captured at a time. I notice that the display is a little
better behaved in 0.6.0. Sometimes the autoranging did some slightly
weird things whereas in this version appears to be more consistent. I
look forward to the multi-frame support in a future release.
I have looked at some of the driver code for scopes some time ago while
I was looking at driver examples to help me with ideas for writing a DMM
driver, but scope drivers seemed on another level of complexity entirely!
Anyway, thank you for your hard work on PulseView and your kind replies.
Regards.

Hello John,
To the sigrok devs,
How is PulseView data capture from my Rigol DS1054Z oscilloscope
supposed to work? When I click Run, a snippet of data is captured and
the capture stops after perhaps just a second. I can expand the
captured data to fit the window and the trace does then resemble what
is on my oscilloscope, but is it supposed to capture only one frame?
Is it possible to configure the number of captured frames somewhere?
Or is capture supposed to be continuous until I click Stop?
Currently, what happens depends on the driver. Some drivers will
acquire a single frame, other will acquire multiple.
All previously released PV versions have a built-in hard limit
that makes PV query only a single frame. I removed this limit,
thinking that I'd be able to finish complete multi-frame support
before the next release but it's not going to happen, so while
there is limited support in place already, the next release will
again be limited to one frame. The one after that won't be anymore,
though.
Historically, PV was heavily geared towards logic analyzers and
scopes were somewhat neglected. While a lot has happened to remedy
this situation, scope support is still full of to-dos. The reason
for this is that it's a very complex undertaking and I can only
do so much :)
I have my own list of things that need to be done, but if users
tell me what they need, I've always been able to shift priorities
when it's justified to do so.
All the best,
-Soeren
