;; Test.asm ---  Test program for the MiniDRAGON+ Rev. D board
;               
;     Function: This is the factory test program for checking on-board
;	   hardware. It checks the 2-pos DIP switches AN5-AN6,
;	   2 pushbuttons AN3-AN4 and the LCD display.
;	   It scans the switches and keypad. Shows their functions and
;                   displays the key number on the 7-segment LED display while
;                   playing a song. It allows to adjust the trimmer pot to change
;                   LED display's brightness.
;
; The switches are software de-bounced for better reliability
;
; Instructions:
;           	If you have a 4 x 4 keypad, connect it to the keypad header J22.
;          	The middle 8 pins of the 10-pin keypad cable are keypad connections.
;         	The pin 1 and pin 10 are not used.
;
;	1. After running the test program, the 7-segment LED display will
;	   count up from hex number 0 to F and the music will come out.
;                    LCD display shows:	" S1=UP, S2=DOWN "
;                                                     "S3=FAST, S4=SLOW"

;	2. press the S1 pushbutton, the number counts up from hex 0 to F.
;	   press the S2 pushbutton, the number counts down from hex F to 0.
;
;	3. Short the S3, the count speed is 250ms per count (fast).
;	   Short the S4, the count speed is 750ms per count (slow).
;
;	4. Adjust the trimmer pot, the 7 segment LED display's brightness 
;	   should change.
;
;                  5. Press the keypad, the 7-segment LED display will show key number.
;
; Ex1.asm  ---- Example program 1 for the MiniDRAGON (c)2002, EVBplus.com
;
;     Function:    Reads 2-position DIP switch and 2 pushbutton switches
;	     via analog port ATD0 and displays the results on the 7-segment
;                      LED at port H
;	     The LED is normally off.
;	     When the sw1 is down the segment a is lit
;	     When the sw2 is down the segment g is lit
;	     When the sw3 is short the segment e is lit
;	     When the sw4 is short the segment c is lit
;
;; The switches are not software de-bounced for simplicity. The switches are
; software de-bounced in the TEST.ASM for better reliability.

;
; Ex2.asm  ---- Example program 2 for the MiniDRAGON (c)2002, EVBplus.com
;		
;     Function:    Flash the word "HELP" on the 7-segment LED

;
; Ex3.asm and ex4.asm are not available on the MiniDRAGON board


;
; Ex5.asm  ---- Example program 5 for the MiniDRAGON (c)2002, EVBplus.com
;		
;     Function:    User can adjust the trimmer pot VR1 to vary the voltage on 
;	      the AN7 (PAD07) of the ADC and to change brightness of the 
;	      7 segment LED display
;
; Ex6.asm  ---- Example program 6 for the MiniDRAGON (c)2002, EVBplus.com
;		
;     Function:    Plays a song via timer5 (PT5)
;
;
;
;5s_delay.asm  5 second delay timer for the MiniDRAGON (c)2002, EVBplus.com
;	
;     Function:   5 second delay routine using output comparator 6
;	    The 7-segment LED will be turned on immediately after running
;	    the program. It will be turned off after 5 second delay. 
;	   Change the DELAY_TIME to 60000 will delay 1 minute
;
 500Hz.asm --- Square wave generator for the MiniDRAGON (c)2002, EVBplus.com
;	
;     Function:   500 Hz square wave routine using output comparator 6
;	    The PH0 LED (segment a) is repeatedly turned on for 1 ms
;                     and then turned off for 1 ms.
;	    User can use a scope to observe the 500Hz square wave
;	    on the PH0 (pin 52 of the MCU).
;	    The PH3 LED (segment d) is repeatedly turned on for 250 ms
;                     and then turned off for 250 ms
;	    User can use a scope to observe the 2Hz square wave
;	    on the PH3 (pin 49 of the MCU).
