Re: Sampling rate - newbie question

sorry to reply to the comedi list about a potentially non-comedi
problem.  have seen other similar posts and thought this might help:

the VI's you got for acquiring waveforms has a subVI called "start cmd"
in order to set the sampling rate you need to set the scan_begin_arg to
the number of nanoseconds between scans, as per comedi documentation.
for example, if you want to sample at 10kHz, you have 1/10 ms = 100000
ns between scans.  so you would set scan_begin_arg = 100000.
in the start_cmd VI there is already a variable created called
scan_begin_arg.
