camera_track_update() locks up

[anty]

When I call the function camera_track_update() in a while loop (just call the function and print out the values of the cam structure), the function locks up the program after about 30 calls. What's the problem here? By "locks up the program", I mean that the function is not returning. Thanks.

You should only need to call camera_track_update() once, and the struct will continually update itself automatically.

Thanks. The camera_track_update() function is called to check if the new data is ready.
