Hi Frank, stop_arg=1 works, thanks. But i think it doesn't solve my problem with the stop signal, because i am always waiting for the next triggersignal. I don't understand the chapter "externally triggered interrupt". Is it possible to get an good example or is there one in the comedilib directory and i don't see it ? Martin Am Mittwoch, 4.
