I did run into some problems when trying to get the PIDController to drive towards my setpoint. The example from WPI above seemed to indicate I need to set my input to 0-5 for a potentiometer. After banging my head for a while and then figuring out how to output PIDController->GetError() to my dashboard I figured out that it is really looking for 0-1024 at least in my application. If you are having trouble getting your PIDController to make sense to you, you might check to see what numbers it is based on for your application.

Does anyone know what it would take to drive the PIDController based on the averagevoltage of the analog input? Would I set it up like:

turretControl = new PIDController(P,I,D, turretPot->GetAverageVoltage, turretMotor)

Or do I have to do something with the other PIDController sub-classes/functions?
I would think that GetAverageVoltage() would suffice.
