IMAQ Sessions

Recommended Posts

Just wondering if I can do this:

If I want to perform a series of operations on the camera, I can do an IMAQdx open camera at the beginning, then feed the output dup IMAQdx session into several subVIs (which take the output IMAQdx session as an input IMAQdx session for some other provided IMAQdx VI like snap), each of which output the dup session again until it finally reaches IMAQdx close camera?

It should be possible, right? I just wanted to check before committing to doing it.

The question is not "is it possible?" but "is it going to do what I expect it to do?" ; answer won't necessarily be the same !

I think you should use a state machine architecture and do the "open session" before the while loop, wire the IMAQ session into a shift register and have a state for each operation you need to perform.

Fill free to ask if you need example to help you code this.

Hope this helps
