Req. for TMX320VC5402 DSK Code - kumar venkat - Nov 10 9:36:00 2001

Hello Group Members, I am working on TMX320VC5402 DSK. I request the group members to help me in this regard. My objective is Given an analog signal of frequency say 1or2KHz from a Function Generator to the Mic. INPUT socket of the DSK i need to get back and display the same input signal at the other end i.e, Speaker OUTPUT socket of the DSK which is connected to Oscilloscope. Basically it is a simple delay program wherein to set the circular buffer and the sampling frequency setting are to be cater for. Analog I/P to the DSK <-- Function Generator(2KHz) Analog O/P of the DSK --> Oscilloscope Request you people, can i get the source code for the above objective. If possible do suggest me how to achieve for the above objective. Advance Thanx Kumar |

Hi Kumar, If I understand your project correctly, there are several example/sample programs (DSP/BIOS and non-DSP/BIOS versions) which are on the CD ROM delivered with your DSK C5402 kit (i.e., codec and codec_bios in the ti\examples\c5402\dsp directory) in which audio samples are copied on a sample-per-sample basis from the mic codec input to the speaker codec output, and it is easy to see where to insert some of your own code in-between if you wish to do some signal processing on the audio samples prior to sending them out the speaker codec. The sample rate is 16 kHz, but you can easily change that. The non-bios version has a bug in vector table set-up which I have not resolved as yet, but the bios version seems to work well. Good luck, -Todd -----Original Message----- From: kumar venkat [mailto:] Sent: Saturday, November 10, 2001 2:36 AM To: ; Subject: [c54x] Req. for TMX320VC5402 DSK Code Hello Group Members, I am working on TMX320VC5402 DSK.
