Re: rescale analog inputs
In prior years*, the use of custom circuits have been allowed in FRC robots. This is an opportunity to use a simple operational amplifier (op-amp) circuit to apply gain and offset to the input and filter the signal to eliminate high frequency noise (i.e. motor/compressor vibrations, electrical power noise). Signal conditioning requires some care, but is not too complicated. Simple evaluation boards can be purchased from op-amp distributors (i.e Digi-Key), not to mention kits.
Have fun!
