 /***************************************************************************
	keybasic.c
	
	Sample program to demonstrate the keypad functions. This program
	will display the following in the STDIO display window:
	
	1. Displays default ASCII keypad return values.
	2. Displays custom ASCII keypad return values.
	3. Demonstrates keypad repeat functionality. 

	Instructions:
	1. Compile and run this program.
	2. Press each key on the controller keypad at least once when prompted.
	3. When the "Key Repeat" prompt appears, press the key and hold it down
	   for a least 1-2 seconds to see the "Key Repeat" feature in action.
