I would like to output 8 simultaneous waveforms from a NIPCI6713. The demo, ao_waveform looks like a good template to start from since it works fine (once the buffer size was expanded). Just to see if I could get more than one channel to output at a time, I changed n_chan to 3 and increased the number of chanlist[] entries accordingly and got the error comedi_command_test: invalid argument Any value of chanlist_len > 2 fails for me. The value of scan_end_arg doesn't matter so long as chanlist_len <=2. I am missing something here. Any suggestions on how to output more than one channel would be appreciated. David
