The design of the interface board enables you to use to choose the CLCD display that is appropriate for your application. The CLCD displays and touchscreens currently available for the baseboard are:


Epson 2.2 inch 176x220 pixel color TFT with LED backlight.


Sanyo 3.8 inch QVGA color TFT with touchscreen and fluorescent backlight


Sharp 8.4 inch VGA color TFT with touchscreen and fluorescent backlight

Six push button 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. 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.
