Using the same wire for positive edge start trigger and negative edge stop trigger for 6533

Question

I would produce a start trigger for an external data source to start them.
Emediatly after this starttrigger this source produces a trigger Signal.
I would like to use this trigger Signal as an extern trigger which should provide some functions:
1. on the positive edge of the Signal some pattern should read in with an external clock.
2. on the negative edge of the trigger signal this process should stop.
I would do this with CVI

Answer 1

Hey Schicki,
I have included two links below that should help you with your application. The first one is setup to perform digital pattern I/O with an external clock in CVI. The second shows how to incorporate start/stop triggers in digital pattern I/O operations. You should be able to combine parts of these two programs to complete your application.
