You are right, the GUI is not quite ready for use yet. However, the
commandline client (sigrok-cli) does work well with the OLS. For example
this should work:
sigrok-cli --samples 64 -o samplerate=1m
It takes 64 samples (of all 32 probes on the OLS) at a sample rate of 1 Mhz.
Triggers work, too:
sigrok-cli --samples 64 -o samplerate=1m -p 1 -t 1=1 -o captureratio=25
That samples just one probe (1), only triggers when it hits 1, and gives 25%
pre-trigger samples in the output. You'll get something like this:
sigrok 0.1pre2
Acquisition with 1/32 probes at 1 MHz
1:00000001 11111111 11111111 10000000 00000000 00111111 11111111 11100000
