How do I acquire 1 image every time an external trigger fires

November 30Hits:0

I am using an NI 1428 frame grabber card and a common apature camera to acquire real time images.
Does anyone know how to listen for an external trigger (ext 0) and after it fires, grab the current image on the frame grabber card? I want to do this inside of a loop that grabs one RGB image everytime the trigger fires.
