11.14.6 USB Joystick

Joysticks are also supported; Buttons, two sets of axes and Hat Switch. A joystick is found

by checking the connection status of system devices.

Position

Each Joystick will hold the current position. First, the user will set the range (min, max) of a

joystick cursor. For example, for an LCD 128 by 64, the following might be used:

// X range = [0, 128] Y range = [0, 64]

Joystick.SetCursorBounds(0, 128, 0, 64);

The current cursor position, can be obtained using: Joystick.Cursor
