What I need is to use a National Instruments PCI-MIO-16E-4 AD/DA to read data from the AD, do some simple operations on it, and output the result on the DA at the fastest possible frequency, with as little jitter as possible. I set up a machine for this with Xenomai3 (cobalt) and everything seems to work. I can run "latency" with max latency around 3-4 us. the analogy libraries are installed, the board is recognized and the test programs are able to read and write to it. The problem is how to write a realtime program for this task. Is there documentation at the basic level on howto do that or some place where I can find examples for similar programs?
