* Test.asm ------- 	Test program for FOX11 board with Wytec Phantom Monitor
*	      	
*     Function:    	This is the factory test program for checking on-board
*	       	hardware. It reads the DIP switch of port C, displays its
*	       	status on the PB0-PB7 LEDs of port B. It tests the pusubuttons
*	       	PC0,PC1,PA0 and the LCD display.
*	       	It scans a keypad and output the key number in binary
*	       	format on the PB0-PB4 LEDs while playing a song. It changes 
*	       	display's brightness by adjusting the trimmer pot.
*
*     Instructions:	If you have a 4 x 4 keypad, connect it to the keypad header J6.
*	       	Before running the test program, place all individual DIP
*	       	switches at the upper positions.
*
*		1. After running the test program, test each individual switch on the
*	    	DIP switch and observe the LED status on the PB0-PB7.
*	   	LCD display shows:	"PRESS PA0 SWITCH"
*                                 			"TO CONTINUE TEST"
*
*		2. Test the pushbutton switches PC0 and PC1 only when the 
*	    	PC0 and PC1 switches of the DIP switch are in upper position.
*		LCD display shows:	"PRESS PA0 SWITCH"
*                               			"TO CONTINUE TEST"
*
*		3. Press the pushbutton switch PA0 and music should come out.
*	    	The PB0-PB7 LEDs should chase.
*
*		4. Adjust the trimmer pot VR1 to change PB0-PB7 LEDs' brightness.
*	   	If you press any key on the keypad, the LEDs should show
*	   	the key number that you pressed in binary format. Key number 00
*	   	is shown as $10.

* Lcd1.asm ------- 	16X2 LCD sample program 1 for FOX11 board with Wytec Phantom Monitor
*
*     Function:      	This is the simplest way to displays a message on a 
*	        	16X2 LCD display module. The cursor is off. 
*	         	If more controls to the display are needed, see the LCD2.asm
*
*                        	The LCD driver source code is included in the example program

*
* Lcd2.asm ------- 	16X2 LCD sample program 2 for FOX11 board with Wytec Phantom Monitor
*
*     Function:   	This program displays a message on a 16X2 LCD display module
*	     	by calling sel_inst(instruction), sel_data and wrt_pulse
*	        	subroutines. These subroutines are used for controlling
*	         	a different type of LCD display.
*
*	         	The LCD driver source code is included in this program

* Echo.asm	 ------	Test BUFFALO I/O for FOX11 board with Wytec Phantom Monitor
*
*     Function:    	Reads keyboard input and output it to PC's CRT screen.
*	        	works like a typewriter.
*
*                        	When a BUFFALO output routine is called by user program,
*	        	the PC's CRT will switch to a new output screen to display
*	       	the characters. It will restore the debugger screen when the
*	        	program is stopped.
*
*	       	After user program is stopped by esc key, it must be 
*	       	re-started from the beginning in order to show the new 
*	       	output screen.
*
*		All EVB/EVBU BUFFALO I/O routines are located at $0FA0-$0FCF
*		in stead of $FFA0-$FFCF.

* Tutor1.asm ------ 	Tutorial program 1 for FOX11 board with Wytec Phantom Monitor
*
*    Function:	This program sums up 4 numbers and store the sum
*		at the RAM locations \sum (0 and 1), its average at
*		the RAM locations \average (2 and 3).
*
*     Instructions: 	1. Use P command to enter the addresses to be 
*		    monitored, such as p \sum, \average.
*		2. Use B command to set breakpoints at addresses
*		    \next and \finish, such as B \next, B \finish. 
*		For your convenience, we did above 2 steps for you
*
*		3. Enter G \start command to run the program
*		   until it stops at a breakpoint address, then enter
*		   G command to run and until it stops at another
*		   breakpoint address. Repeat the G command until it
*		   stops at \finish.
*		   when it stops at each breakpoint address, you can
*		   watch the values at the locations \sum and \average.
*
* 		You can also verify the result using the F7 math
*		function key at each stop.

* Tutor2.asm ------ 	Tutorial program 2 for FOX11 board with Wytec Phantom Monitor
*
*     Function:	This program flashes the PB5 LED when the PA0 switch is down.
*		It shows how to use a subroutine call and change the contents
*		of the RAM location \fls_rate to vary flash rate.
*
*     Instructions: 	1. Use B \pa0_low command to set a breakpoint at the address
*		    \pa0_low.
*		2. Enter G \start command to run the program
*		    and nothing should happen. Then press and hold down the 
*		    switch PA0, the program should stop at the
*		    address \pa0_low, because the PA0 is normally high,
*		    it becomes low when it's down.
*		3. Remove the breakpoint address \pa0_low by using K
*		    command, such as K \pa0_low. After the breakpoint is
*		    removed, then enter G command to run the program again.
*               		4. At this time, the PB5 LED should flash when the pa0 switch
*		     is down.
*		5. Stop the program by ESC key and use E command to
*		    change the value of the \fls_rate from $8B to $FF,
*		    such as E \fls_rate.
*		6. Run the program by entering G command and the LED should
*		    flash slower when the PA0 switch is down.
*		7. Repeat the steps 5 and 6 to change the fls_rate from 
*		    $FF to $40, and the LED should flash faster.
