: P.S. I know that something like this works because we do a similar scaling in order to 'zero' our joysticks. We got tired of ripping off the tape we have covering the trims on the joystick in order to prevent our robot from drifting off on us. It really works well. If you see Jeremy 'The Stamp2 Guru' Husic in the pits, I am sure he'd show you the code and give you a demo. JJ.

We got around this by programming a dead zone in the center range of the
joystick. If the input value is in the range 118-138 it is set to 128.

This doesn't eliminate the need for taping the trimmers, but we haven't
had to readjust them yet.
