"*" is the knob. Rotating the knob corresponds to "left stick, X axis", and pressing the knob resets that axis.

Robot project integration

Simply create a CommandXboxController as you normally would and bind commands to buttons using the CommandXboxController.button(int button) method. Access the encoder value by using CommandXboxController.getLeftX().

private CommandXboxController m_keypad = new CommandXboxController(1);
...

m_keypad.getLeftX();
m_keypad.button(0).onTrue(Commands.print("Hello, world!"));
