In this demo, the board will act like a USB mouse using the accelerometer as a tilt sensor. Hold the board flat relative to the ground for no movement.  If it is difficult finding the mouse cursor on the screen, please make sure that the board is flat relative to the ground.  Tilt the board to move the cursor.  Press the ‘L’ button to left click and the ‘R’ button to right click. Hold the menu button to return to the demo menu and to load a different application.
