If you cover up the camera, it should start searching for the light. If you look in the 1577camera.c we supplied, in the search() function it says:

if (xerror != 0 && yerror != 0)
     track();

That means that if the xerror and yerror are NOT 0, the camera should track the light. If the xerror and yerror ARE 0, the camera should perform a search as written in the code.
I don't know why your camera doesn't perform that search but i know it should...
This code works for us very well, but maybe we should add an 'else' after that 'if'.
Anyway, are you sure you followed all of the instructions in the readme we made?
