Well, the code works to communicate with the AVRcam, but that doesn't mean it does anything useful yet.
I am having a very hard time getting settings and colormaps on the camera to isolate colors well enough to track them. It is also very dependent on lighting conditions. Since the same camera module (OV6620) is used in the CMUcam and the Blackfin, I am still hoping it is possible. But so far I am not having much luck. I will try again in better light this weekend and see if I can get something that I can video.
I wish I had better news.
The next phase of this project is to rewrite the AVRcam firmware to test other methods of using the camera besides the colormap code that comes with it.
