I was dubious when you guys started talking about the Victors calibrating the high and low ends. I thought it only re-centered the neutral point. (Yeah, I know that, with some reflection, that doesn't make a lot of sense, but, ... what can I say?
) Anyway, I found this in the Victor User Manual:
Quote:
Calibration Instructions:
The Victor 883 is pre-calibrated to values compatible with the FIRST control system. No calibration is required for normal operation.
NOTE: While in calibration mode, the Victor 883 will record the maximum PWM value detected as ‘full forward’, the minimum PWM value as ‘full reverse’, and ‘neutral’ will be the PWM value recorded at the release
of the Cal button.

(And it then goes on to give directions for calibration.)
So my new flip-flop position is that you may indeed want to calibrate your Victors to match your joysticks. However my weasel words to the wise are that calibrating the Victors to untrimmed joysticks could have deleterious effects on your autonomous code!
Let's say your joystick is badly out of trim, and you've calibrated your Victors to believe that 100 is full forward, 50 is neutral, and 0 is full reverse. You probably won't have also calibrated your autonomous code to output those same values, so your robot will end up doing some very strange things during autonomous mode. (Unless, of course, you have a very sophisticated auto mode with sensor feedback which can compensate for the miscalibration.)
