Your triggered "Pre-Grab" timings have an extremely large variance. Keep in mind that the slave/triggered camera needs to be idle before and during the entire trigger period (i.e. not in exposure mode or transfer mode). You need to do the math to ensure that your trigger cycle (50ms) - 3*stdev - exposure (30ms) > 0.
I don't have a uEye camera with me, but I definitely remember using ueyedemo to test out external triggering mode. Go through every one of the settings (wrench icon). If that fails, save the camera configuration to a file, open it, modify the external trigger settings manually, then load that config file.
I'm using 2x UEyeSE synchronised externally in hardware.
I cannot seem to get my desired 20 Hz framerate when using the trigger. I have my hardware trigger signal's cycle time set to 50ms. Exposure is set to 30ms. I verified that the trigger signal is just fine. Timings for trigger :
In free-run, it works fine, and can go upto 25hz. Timings for free-run :
I have also tried various different cables, different ports, etc.
Could you help? I couldn't also figure out how to use
ueyedemo
with triggering enabled, to check if the actual driver grab was working at desired rate.
