Position and velocity PIDControllers using same encoder

However, this is overkill, as you can pass the same instance of an encoder to 2 separate PIDController objects. This would be my recommended way, as constructing 2 separate encoder objects actually takes away an encoder you could use for another purpose, whereas 2 PIDController objects with the same encoder object wouldn't take any extra resources.

Yeah, but you can't send the same encoder object to two separate PIDController objects and have it be a kRate source for one of them and kPosition source for another. Hence the wrapper idea, which is ugly but would probably work.

Oh I guess thats true. A small wrapper class would allow that however, and that class should be pretty thin.

Here's a wrapper that 2485 wrote that does this.
