/* Complete USB Joystick Example
Teensy becomes a USB joystick with 16 or 32 buttons and 6 axis input
You must select Joystick from the "Tools > USB Type" menu
Pushbuttons should be connected between the digital pins and ground.
Potentiometers should be connected to analog inputs 0 to 5.
This example code is in the public domain.
