Six pushbutton switches are mounted on the interface board below the 2.2 or 3.8 inch
display. The state of the switches can be read from the touchscreen controller interface.
The touchscreen interface on the CLCD interface board is described in Touchscreen
controller interface on page C-11. The selftest program supplied on the CD reads the
position of a pen on the touchscreen and displays it on the CLCD or VGA display
connected to the board.
The 2.2 and 3.8 inch CLCD displays and the adaptor board are mounted in a small
enclosure as shown in Figure C-2.
