Image acquisition with QImaging cameras

I've been trying to use a QImaging camera and the Qimaging XOP available on the IGOR ftp site. I can acquire frames and most of the XOP functions work, but my goal is to have external triggering drive frame acquisition. However, TTL triggering does not cause immediate frame acquisition. My configuration is: Windows XP-32, Igor 5.03, QiCam Driver 2.04.

I was wondering if anyone had more success with the XOP to acquire frames using an external trigger system (to allow easy sychronization with light sources and electrical data acquisition). Or if anyone has more experience with C coding and has modified the XOP to make this possible.

I'm also open to using other cameras (Hamamtsu, etc.) if anyone has written their own XOPs and would be willing to share.


Thanks.
