When the camera is not hooked up (therefore preventing any serial communication), the light is almost steadily on. As soon as I hook up the camera and serial communication is established, the light slows down quite noticeably.

Also, I tried putting limit switches on a moving part of our robot, but they took much longer than 1/40 of a second (26.6ms) to respond. The response time was more on the order of 1/4 of a second! This ate several limit switches, unfortunately.

All the code I have mentioned was placed within the main "26.6ms" loop. I am basing my code off of last year's camera code; were there improvements made for this year? I was under the impression that last year's default code used buffered serial communications; however I am at a loss to explain this behavior.

Can anyone help me on this? Maybe someone from IFI (hint hint)?

Thanks,

Eldarion
