255 can do some wierd stuff. Way back in 2003, I couldn't figure out why our robot wouldn't drive straight. Another team pointed out that 255 was some sort of null character. I changed it to 254, and the thing started driving perfectly.

The X axis sets the "desired" heading.
Last year we found that our robot could massively out-spin the maximum rotation rate supported by the gyro. What do you do once the gyro reading goes 'beyond' the maximum/minimum of the chip?
