i´m using a PCI 6221. Is it possible to generate to different and independent pulses on ctr0 and ctr1. I am using ctr1 to trigger a camera and i need a second independent pulse to control a steppermotor-card. Is there any possibility to do that?
If you want to generate a continous pulse train the answer is yes.
But when generating a finite pulse train, both counters will be needed for for this.
Christian is absolutely correct. I just wanted to make it clear that you may generate single pulses on each counter independently. The only limitation is with generating a finite (greater than 1) train of pulses. Older hardware requires the use of both counters to generate the finite pulse train. X Series boards and cDAQ chassis (other than the 9172) do not have this restriction.
There's one other sneaky thing you might be able to do if this app isn't using AI and/or AO. You can configure finite sampling tasks for the AI or AO subsystem and then export its sample clock signal to a PFI pin.
You might be able to operate your stepper for a finite number of steps at a constant pulse rate this way. You probably will want to use a real counter to get the timing right for your trigger signal.
