How to navigate the demo menu
Four basic elements constitute the hardware of the system user interface: a 320 x 240 TFT
LCD display, a resistive touchscreen, a 5-way (left, right, up, down, selection) micro-joystick
and a pushbutton “Key”.
The joystick is primarily used for navigating between the various menu screens, within a
screen and between screen items. In addition, the joystick allows the selection and editing of
item values.
