Running a task with a period of 10us is usually considered a bit out of the scope of Xenomai. Nevertheles, there were some recent improvements on Xenomai trunk that might make this possible. It would be interesting if you tested this with trunk and tell us whether it works. Also note that in order to get ultra-low latencies, you have to properly calibrate the nucleus latency (/proc/xenomai/latency). > May be better to use only ADEOS functions for my task, is it faster then > RTDM? Adeos has no notion of a "task", so, you would have to implement your task in an interrupt handler, and yes, you would get better performance (see for example the difference between latency -t 2 and latency -t 1). > What is the state of RTAI nowadays, is it still a live? Well, you are not asking on the right mailing list. Try RTAI mailing list. -- Gilles Chanteperdrix
