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. 1.4 Reviewing the Code ====================== 1) Double-click on the daa_bios.c file in the Project View. You see the source code in the right half of the window. 2) You may want to make the window larger so that you can see more of the source code at once. You can also choose a smaller font for this window by choosing Option->Font. 1.5 Building and Running the Program ==================================== Code Composer Studio automatically saves changes to the project setup as you make them. In case you exited from Code Composer Studio after the previous section, you can return to the point where you stopped working by restarting Code Composer Studio and using Project->Open. To build and run the program, follow these steps: 1) Choose Project->Rebuild All or click the (Rebuild All) toolbar button. Code Composer Studio recompiles, reassembles, and relinks all the files in the project. Messages about this process are shown in a frame at the bottom of the window. 2) Choose File->Load Program. Select the program you just rebuilt, daa_bios.out, and click Open. (It should be in the c:\ti\myprojects\daa_bios folder unless you installed Code Composer Studio elsewhere.) Code Composer Studio loads the program onto the target DSP and opens a Dis-Assembly window that shows the disassembled instructions that make up the program. (Notice that Code Composer Studio also automatically opens a tabbed area at the bottom of the window to show output the program sends to stdout.) 3) Click on assembly instruction in the Dis-Assembly window. (Click on the actual instruction, not the address of the instruction or the fields passed to the instruction.) Press the F1 key. Code Composer Studio searches for help on that instruction. This is a good way to get help on an unfamiliar assembly instruction. 4) Choose Debug->Run or click the (Run) toolbar button. Analyze results (see below). 5) Choose Debug->Halt or click the (Halt) toolbar button to end the program. 1.6 Expected Results ==================== Running your program enables you to utilize an independent phone line (second line, cell phone, etc.) to talk to the DSK. This telephone interface allows the DSK user to listen through the speakers and respond to the caller by microphone.
