Problem with freezing frames in LabVIEW

[Peter H]

We see a similar problem. We start Labview, power up the camera, select the COM port, and select Grab Frame. The green Download Progress bar advances and the red LED blinks. Usually the Frame Grab window shows a frame; sometimes only a white screen. The red LED shuts off. Periodically the green Download Progress bar advances, but with no red LED blinking and no new frame shown. We select the Grab Frame button, and it grays out.

The manual servo controls move the camera gimbals if we move them before selecting Grab Frame; after, the controls move, but the gimbals do not.

Apparently the PC loses communication with the camera after it tries to collect the first frame.

How do we fix this problem?

Peter,

Try the test version of the CMUCam2 App here and let me know what your results are. I'm not able to reproduce the behavior you guys are seeing on my hardware so I need your feedback to get this thing working for you.

Good Luck!
