2.5 JOYSTICK AND FIRE BUTTON
The Multimedia Expansion Board provides a four direction joystick with a fire button
(Figure 2-9). The directional joystick and fire button can be used to interact with and
provide feedback to an application. The joystick (S2) is also connected to the fire button
(S1), as shown in Figure 2-10, which allows the user to press either the fire button or
the joystick to register a fire command.
