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.
