I am trying to get simultaneous analog input and output working with a National Instruments PCI-MIO-16E-1 with comedi-0.7.65. When I tried to perform analog output of a fixed length waveform, part of the waveform was truncated. It seems that the truncation is dependent upon the sample rate, and the number of samples. scan_begin_arg=20000, sending 1122 samples, drops 622 scan_begin_arg=20000, sending 1025 samples, drops 626 scan_begin_arg=15000, sending 401 samples, drops none scan_begin_arg=15000, sending 511 samples, drops none scan_begin_arg=15000, sending 1067 samples, drops 517 These results are with comedi-0.7.65. I had similar results with the cvs snapshot from 2002-July-29. If you want to see my code, it is available at: http://www.newimage.com/~rhk/aotest.c -Ray
