	This sample program is for the OP6800 series controllers.

	This sample program demonstrates the use of the OP6800 Demo board
	with the controller. The program will turn-on a LED and display a
	message on the LCD when a switch press is detected.   
	
	1. Connect a +12v power source to the OP6800 Demo Board connector
	   J2 as follows:

	   PS     	OP6800 Demo Board
	   --			-----------------
	   +12v		+RAW J2, pin 4 
	   GND      GND  J2, pin 1

	Test Instructions:
	------------------
	1. Compile and run this program.
	2. Press one of OP6800 Demo Board switches SW1 - SW4 (continuously) to
	   see a message displayed on the LCD and light-up a LED. Here's a list
	   of how the switches are connected.
