Code for joystick bindings for xbox controller using WPILib for FRC (copied from https://github.com/bobwolff68/FRCTeam1967). "Team 1967 created a Janky Joystick Investigator that puts button and axis values on SmartDashboard. That way when you click a button or move a thumbstick you will be able to figure out which button number/axis that physic…
