Hello Soeren,
if I understand correctly:
Currently libsigrok soft-trigger module is used in some logic analyzer
drivers for prebuffering samples and waiting for trigger event (multi
channel condition). I think this type of trigger mode is called single
trigger.
I would like the capture session to continue running and keep checking for
trigger events.
Oscilloscope like trigger mode is called: repeat

End result: pulseview (zoomed in on trigger event) would show latest
trigger event until new arrives.
Example: I2C communication, start condition
-Ziga
I have an idea how to do that on saleae logic clone, will try to implement
it tomorrow.
Didn't use sigrok-cli yet so I can't comment on its use.
