IMAQ Continuous Acquisition While Waiting for Trigger

[gswang]

I have an IMAQ board that I'm using to continually grab images from an external camera. The problem is that I also need to be waiting for trigger pulses on the same card.

Right now, I'm using a LabView program via Grab Acquire / Grab Setup to do the continuous acquisition. I would also like it to do some special behaviors (such as saving the next 5s of images in a separate file, etc) whenever it gets a trigger signal. However, using the ConfigureTrigger block leads to an error.

I have to guess that they're both trying to place some kind of a lock on the camera. 

Any ideas on how to resolve this?

Hello gswang,

What is the card that you are using for acquisition?

I would suggest to start by working with LabVIEW's shipping example (Help > Example Finder > IMAQ or IMAQdx (epending on your camera) > Signal Input & Output > Trigger Snap or Trigger Grab
