I am using a 6602 PCI to collect an array of time stamps of pulses using DAQmx.dll i.e. .NET. c#. In order to synchronize the 2 encoder tasks data for comparison, I create a "starter" task that is triggered by a digital edge trigger (a PFI). Then I create a task for each encoder and make their digital edge triggers point to the output of the "start" task.
This is all working very well, but I have been asked to make a modification so that instead of a single PFI being used as my digital edge trigger, a combination of PFIs can be used (AND/OR). From my research so far, I think this can be done with a digital pattern trigger, but since I am collecting counters, I am using an ArmStartTrigger and ArmStartTrigger does not have a digital pattern trigger, only StartTrigger does. Sooo, my question is how do I do it? My guess is that I can replicate what ArmStartTrigger does using only the StartTrigger, but I do now know how. I am also open to AND/ORing the ArmStartTrigger, but I haven't seen where that's possible.
Thanks so much for your time.
