Detailed Description

Handle input from NiDsXbox controllers connected to the Driver Station.

This class handles NiDsXbox 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.

Only first party controllers from Microsoft are guaranteed to have the correct mapping, and only through the official NI DS. Sim is not guaranteed to have the same mapping, as well as any 3rd party controllers.
