edu.wpi.first.wpilibj.PS4Controller
public class PS4Controller
extends GenericHID
Handle input from PS4 controllers connected to the Driver Station.

This class handles PS4 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.
