Hi,

I finally managed to return to the site where we have the National
Instruments PCI-6711 board. The old problem with analogy_ni_pcimio
seem solved. I can attach the driver and cmd_write seems to work.

I have been trying unsuccessfully to modify cmd_write to generate a
waveform. What I would like to do is to generate a sawtooth waveform
and send a digital pulse (trigger for an infrared camera) at the end
of the waveform. That should be running continuously until stopped.

I tried to modify your example "cmd_write" and the comedi programme
called "ao_waveform.c ". Many commands seem not to be implemented on
the analogy side. I tried to use the documentation on the comedi site
and the API description on the xenomai/analogy side but I got  even
more confused. It does not seem like a simple matter of exchanging
comedi_  for a4l_ as you indicated in one thread.

Do you have any example similar to ao_waveform.c I could try to modify
for my application? That would be a start. I have been unsuccessfully
searching the threads for something vaguely similar.

All the best
Ettore
