Overview

The Digilab Digital I/O board 2 (the DIO2) is

one of several expansion boards designed to

mate with Digilab system boards. The DIO2

board provides an assortment of frequently

used digital I/O devices, many of which are

controlled by an on-board Xilinx XC95108

CPLD. The CPLD also provides a bus interface

to simplify communications with Digilab

system boards. DIO2 boards can be combined

with Digilab system boards to implement

projects ranging from basic logic designs to

general computer systems, without the need for

any other components.

DIO2 board features include:

• A XC95108 CPLD for I/O device and

system bus control;

• A 16x2 character LCD with integral

Samsung controller IC;

• A four digit seven-segment LED display;

• 16 individual LEDs of various colors;

• An 8-bit VGA port;

• A 15-button keypad;

• 8 slide switches;

• A PS2 mouse/keyboard port;

• An on board 5VDC regulator.

The CPLD comes pre-configured with the

circuit shown in Appendix 1, but it can also be

reprogrammed from any Xilinx CAD tool,

including the free WebPack tools available

from the Xilinx website. CPLD configuration

can be accomplished using the Xilinx JTAG

cable or the Digilent XC95 programming

board.
