It's force of habit. We do all our logic on signed chars by subtracting 128 from the unsigned chars. It makes us off by 1 here and there, but we don't risk over or underflowing on endpoints.

Slightly off-topic, since the new controllers were introduced in 2004, I haven't had an issue with the full 0-255 range on PWM outputs. 255 seems to be a valid value, has anyone had any issues?

I haven't hit 255 on the OI analog inputs though.
