Last year, we spent a day trying to figure out why our robot would suddenly do a little dance and make the light blink on and off whenever we commanded full forward. We reduced the limit to 254 and it went away. Some software religious thing, I figured. It wasn't until after shipping that I was able to go back and realized that the 255,255 was the serial output initialization identifier. Everytime the second STAMP processor sees a 255,255 it thinks that there is a new stream of data so the next byte is PWM1 and the one after that is RelayA, etc.
The good thing was that I was able to help out another team at Nationals with this tidbit of information and they were able to get their 'bot up and working. They were quite grateful.
