public class XboxController
extends GenericHID
Handle input from Xbox 360 or Xbox One controllers connected to the Driver Station.

This class handles Xbox input that comes from the Driver Station. Each time a value is requested the most recent value is returned. There is a single class instance for each controller and the mapping of ports to hardware buttons depends on the code in the Driver Station.
