Directions for loading, building, and using an audio effect on the ADSP-21065L.

1.) Plug the power supply into the board and attach the serial cable to the board and your computer.
2.) Open the VisualDSP Environment shortcut in the start menu.
3.) Inside the VisualDSP Environment, open the ..\Audio Demos subdirectory.
4.) Choose which audio effect you wish to use.(ie: Rotating Speaker Emulation)
5.) Go to the subdirectory of the effect you want to use.
6.) Open the project file (.dpj) for the effect you want to use.
7.) Go to Project, Rebuild All, in order to rebuild the effect for use.
8.) When the build has completed, go to Project, Debug, in order to start the debugger.
9.) Hit the reset button when the dialog box requests a reset of the board, then hit OK.
10.) You should now get a dialog box that says “Communication Success”, hit OK.
11.) You should now get a dialog box says “Target Halted at Breakpoint”, hit OK.
12.) Go to Debug, Run to start the program on the board.
13.) Start the input (ie: cd player, microphone, etc.)
14.) You should be hearing output at this point.


Troubleshooting

If you don’t hear any sound coming out of the output:

-->You must configure the system for either Line in or Mic in input.

Configuring the system for either a Line in or Mic in input:
    Hardware Settings:
	Both jumpers, jp1 and jp2, need to be on either the Line in or the Mic in setting on the board.
    Software Settings:
	Open up the project file(.dpj) inside the Visual DSP Environment for whichever effect you want to use (ie: rotating speaker emulation).  Open the file called AD1819a_initialization.asm.  

If you are using a microphone input set activate the line:
#define 	MIC_INPUT	0
and comment out the line:
#define 	LINE_INPUT 	1

If you are using a Line in input, then activate the line:
#define 	LINE_INPUT 	1
and comment out the line:
#define 	MIC_INPUT	0

Recompile the code through the VisualDSP Environment using the steps shown above.
