This demo uses the starter kit as a USB joystick.

To test the joystick feature, open the Game Controller applet in the Control Panel. In

the interactive test display (Figure 2-4).

FIGURE 2-4: JOYSTICK DEMO PROPERTIES DIALOG

The following controls are implemented in the Joystick Demo:

1. X-Axis/Y-Axis: The movement of the cursor around the white area is controlled

using the on-board accelerometer. Like the Mouse Demo, acceleration on all

three axes is used to compute board tilt, which is then converted to movement

on the X and Y axis. While holding the starter kit board so that the USB connector

faces towards you, tilt the board to the right and left to change the X-axis position.

Tilt the board up and down to change the Y-axis position.

2. Z-Axis: The Z-axis is controlled using the scroll bar. Touch the bar and slide your

finger towards the bottom or top to change the Z-axis position.

3. Z-Rotation: Rotation around the Z-axis is controlled with the potentiometer.

Rotate the potentiometer to change the rotation.

4. Buttons 1 and 2: Of the 13 buttons displayed, buttons 1 and 2 are controlled

using the L and R touch pads, respectively. Press and hold the pad to turn on

(light up) the corresponding joystick indicator.
