TMS320VC5402 DSK - DAA DEMO --------------------------- This example demonstrates the use of the telephony interface of the DSK. The DAA and handset codecs are setup and then the application waits for an incoming ringer. On the second ring detected, the line is picked up (off-hook) and a conversation can be carried out between the DAA and handset interfaces. 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 a line simulator to the RJ-11 (telephone) socket on the DSK board and plug a handset into the simulator. 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 codec demo program (executable), "daa.out". Run the DSP. The LED's on the DSK will start blinking. 6. Pick up the telephone handset connected to the line simulator and dial the DSK board. Refer to your line simulator documentation for instructions on how to do this. 7. 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.
