 TMS320VC5402 DSK DAA EXAMPLE (USING DSP/BIOS)
                      =============================================

This example demonstrates the use of the telephony interface of the DSK.
The DAA and handset codecs are set up and then the application waits for
an incoming ring.  On the second ring detected, the line is picked up
(off-hook) and a conversation can be carried on between the DSK and
handset interfaces.  The example also shows some features of DSP/BIOS.

Below are instructions on how to run this demo:

1.  Connect a microphone to the MIC socket and a speaker to the SPKR socket
    on the DSK board.

2.  Connect an analog phone line to the RJ-11 (telephone) socket on the DSK
    board.

3.  Connect your parallel port cable to the parallel port connector on the
    DSK.  You may use an XDS510 connector if you have one and wish to do so.

4.  Connect the power supply to the DSK board and power it up.

5.  Start up Code Composer Studio and load the accompanying daa_bios.out (i.e.,
    c:\ti\c5400\dsk\examples\dsp\daa_bios\daa_bios.out); File->Load.  If you prefer
    to create your own project, see the guidelines listed below.

6.  Click Debug->Run.  The LEDs on the DSK will start blinking.

7.  From a second phone line, dial the DSK board.

8.  After the second ring, the line will be picked up by the DSK.  You
    should now be able to hold a conversation between the mic/speaker
    interface and the telephone handset.

Getting Started
===============

The following instructions enable you to build and run the daa
example.  You do not have to create and build a project.  If you
prefer to see a quick demo, you can open CCS and load the file
c:\ti\c5400\dsk\examples\dsp\daa_bios\daa_bios.out. 

1.1  Creating a New Project
===========================

1) If you installed Code Composer Studio in c:\ti, create a folder
called daa_bios in the c:\ti\myprojects folder. (If you installed
elsewhere, create a folder within the myprojects folder in the
location where you installed.)

2) Copy two source files from the c:\ti\c5400\dsk\examples\dsp\daa_bios\
{daa_bios.c, daa_bios.cmd} folder to this new folder.

3) Copy two library files to your new folder.  The library files
are in the c:\ti\c5400\dsk\lib\{drv5402.lib,dsk5402.lib} folder.

4) From the Windows Start menu, choose Programs->Code Composer
Studio 'C5000->CCStudio. (Or, double-click the Code Composer Studio
icon on your desktop.)

Note: Code Composer Studio Setup

If you get an error message the first time you try to start Code
Composer Studio, make sure you run Code Composer Setup after
installing Code Composer Studio following the Quick Start Guide.

5) Choose the Project->New menu item.

6) In the Save New Project As window, select the working folder
you created and click Open.  Type "daa_bios" as the filename and click
Save.  Code Composer Studio creates a project file called
daa_bios.mak.  This file stores your project settings and references
the various files used by your project.

1.2 Adding Files to a Project
=============================

1) Choose Project->Add Files to Project. Select daa_bios.c and click Open.

2) Choose Project->Add Files to Project. Select Linker Command File
(*.cmd) in the Files of type box. Select daa_bioscfg.cmd and click Open. This
file maps sections to memory.

3) Choose Project->Add Files to Project. Select Object and Library
Files (*.o*, *.lib) in the files of type box. Select drv5402.lib and
click Open.  Repeat this procedure for dsk5402.lib.

4) Choose Project->Add Files to Project. Select Configuration Files (*.cdb)
in the files of type box. Select daa_bios.cdb and click Open.

5) Expand the Project list by clicking the + signs next to Project,
daa_bios.mak, Libraries, and Source. This list is called the Project View.

Note: Opening Project View

If you do not see the Project View, choose View->Project. Click the
File icon at the bottom of the Project View if the Bookmarks icon is

1.3 Changing Project Build Options
==================================

1) Choose Project->Options.  Click the Compiler Tab in the Include
Search Path.  Type in c:\ti\c5400\dsk\include.  Click 'OK'. This will
enable the appropriate board.h and type.h files to be included.
When building the program, Code Composer Studio finds files by
searching for project files in the following path order:

o The folder that contains the source file.

o The folders listed in the Include Search Path for the compiler or
  assembler options (from left to right).

o The folders listed in the definitions of the C54X_C_DIR (compiler)
  and C54X_A_DIR (assembler) environment variables (from left to
  right). The C54X_C_DIR environment variable defined by the
  installation points to the folder that contains the rts.lib file.
