Actually the command support for 818 has only recently been re-enabled in CVS (Apr 11). https://cvs.comedi.org/cgi-bin/viewcvs.cgi/comedi/comedi/drivers/pcl818.c Unless you really need hard realtime there is no need for RTAI (but it shouldn't interfere). > I was thinking about removing rtc to release IRQ 8 for DMA mode 3, but > DMA mode 1 should work, isnt it? Yes it should. I've used the comedi driver on both an 818 and 818H in DMA mode without problems. And rtc isn't going to do you any good because that code has been disabled in the driver. > I'll be really greatfull for any help and suggestions. Try to check /proc/interrupts (and/or insert debugging statements into the interrupt handler (e.g. re-enable line 776 of pcl818.c) Post the info here (after re-compiling and re-running the command) and we'll see where it leads :) good luck Nils
