If it's a real time problem (it smells like one :-)) ) you need a real time system, e.g. RTAI. It might work like this: * create an RTAI task * make task periodic in the task (via kcomedilib) * read samples (comedi_do_insn()) * do stuff (calculations etc.) * write samples (comedi_do_insn()) I think it's also possible to combine this method and comedi_command (for increased performance and decreased jitter in the sampling periode). hth, Nils -- Institut fuer Schweisstechnik und Fuegetechnik (ISF) Pontstrasse 49 der RWTH Aachen D-52062 Aachen ISF - Welding and Joining Institute fon: +49 (0)241 / 80-96274 RWTH - Aachen University fax: +49 (0)241 / 80-92170
