I would like to trigger an analog input scan with a digital output write directly on the trigger input line of the NI PCI-6036E. At the moment I write a pulse on one of the 8 DIO lines of the card, and I have an electrical physical connection from this digital output to the trigger input (PFI/0). I think (from the card specifications) that it is also possible to trigger the analog input scan by writing directly to the trigger input line, and I wonder if anybody succeeded in getting this done with comedi. In addition to TRIG_INT I also tried to use TRIG_EXT and the DIO line #0 of subdevice #7, with no success. Greetings, -- Alberto
