Hi! My first problem is the number of samples which seems to be limited: If I use 'insn -N 256' all works fine but if I use 'insn -N 257' I get the error message: '/dev/comedi0: Invalid argument' !? If I use the 'cmd' demo I can convert up to 16384 samples. If I request more (e.g. 'cmd -N 16386') I get 24576 samples? (or if I request 30000 samples, I get 32768 samples) And the other problem is: If I use the 'cmd' demo, the unipolar ranges don't work - they act like I'd requested a bipolar range (means: correct gain, but bipolar instead of unipolar setting). But they work fine with the other demos (tested with inp, inpn, insn) I'm using a linux-2.4.24 kernel with RTAI 3.0 and comedi 0.7.67 with comedilib 0.7.21. Any clues what I'm doing wrong? bernhard
