I am trying to output a train of pulse based on a digital trigger (GO bit). When the GO bit goes high, I want to output a pulse train after an initial delay (ie: 2 seconds). When the GO bit goes low, I want to stop this pulse train. When the GO bit goes high again, I want to start the same pulse train with the same initial delay.
The output pulse train has 2 frequencies so I am using 2 counters that generate the same pulse but one of them is delayed by a certain amount. Then I combine the output from both counters into one output using simple BNC T connector. Since I am using 2 counters (max # of counters available to me), I can't create a finite pulse train.
If I use a pause trigger, the only problem is that the second time the GO bit goes high, the initial delay is not used (each channel or counter has a different delay).
So far the only way I can think of is by software timing the counter (by counting the time since the task has started) and stopping the task once certain amount of time has passed. Then I wait for a second trigger which should start the pulse train again with the initial delay.
Is there a better way to do this?
