Overview:
=========

	This application demonstrates OS µCOS-II configuration and use of BF548 Ez-Kit for Media Player type projects. 
	The application uses:
	- ADI's lcd driver to display the content of the harddisk.
	- ADI's Keypad driver to provide user interface to select file or directory, play and stop audio file.
	- ADI's Thumbwheel driver to provide user interface to increse/reduce audio volume and to play audio file.
	- ADI's File System Service to read MP3/Wave file from HDD and plays it over AD1980 AC'97 Audio codec.
	- ADI's Uart driver to provide debug/trace output.
	- ADI's AAC decoder library
	- ADI's MP3 decoder library
	- ADI's WAV decoder library
	- ADI's JPEG decoder library

	The application configures AD1980 in Slot-16 mode and enables Pseudo Multi-Channel Audio playback.
	AD1980/AC97 driver supports almost all industry standard sampling rates 
	(96kHz, 88.2kHz, 64kHz, 48kHz, 44.1kHz, 32kHz, 24kHz, 22.05kHz, 16kHz, 12kHz, 11.025kHz and 8kHz)

Getting Started:
================

	1)	Connect a UART serial cable form the EZ-KIT to a PC. Open a terminal emulator application 
	    	and set the following:
	    	BAUD RATE: 57600
	    	PARITY:	   None
	    	Stop bits: 1
	    	Data bits: 8

	2)	Copy media files to a FAT16/FAT32 formatted HDD, SD Card, or USB Memory stick.  Sample media files can
	    be found in \Media\Audio and \Media\JPEG.  
	    
	    File transfers from PC to/from HDD can be done via a VDSP example program. 
	    \Blackfin\Examples\ADSP-BF548 EZ-KIT Lite\Drivers\usb\mass_storage_app
	    
	    The HDD can be formatted via a VDSP example program.
	    \Blackfin\Examples\ADSP-BF548 EZ-KIT Lite\Services\File System\HardDisk\HardDiskFormat 
	    
	3)  Attach removable media (SD or USB memory stick if applicable)
		
	4)  Load Project file "MediaPlayer_BF548.dpj"
	
	5)	Build Project by selecting "Project->Rebuild Project".
	
	6)  In VDSP, select "Debug->Run".
	
	7)  Run. On the EZ-KIT LCD display, you should see the local drives and be able to view
		their content.  The display shows the content of the root-directory of the drives.
			    
	8)  The EZ-KIT keypad provides user interface to select a file or sub-directory.
	
		- key(up arrow) 	= Previous(moves to the previous selection on the list).
		- key(#2) 			= Play / Pause (enter into sub-directory or play selected audio file).
		- key(#3) 			= Stop playing audio file.
		- key(#down arrow) 	= Next(moves to the next selection on the list). 
		- key(#0) 			= Volume down 
		- key(#Help) 		= Volume up 
		- key(2ND)			= Terminate program
		
		The EZ-KIT thumbwheel also provides user interface as follow:
		
		- turn clockwise to increse audio volume 
		- turn anti-clockwise to decrese audio volume 
		- push down to enter into sub-directory or play selected audio file
		
	9)  JPEG media files are displayed when selected and the Play keypad is pushed.  The JPEG file 
	    stops displaying when the user pushes the Down Arrow or Up Arrow keypad.
	    
    10) Audio media files are decoded when selected and the Play keypad is pushed.  They will stop playing
        at the completion of the file or when the user presses the Stop keypad.
