TI-Board DSK 6713 for audio applications

Started by JoSo July 11, 2007
My goal is to implement a template structure on the DSK 6713.  This
template is to contain a structure for audio input/output, so that an
algorithm can easily be fit into that template structure (for example a
filter or a controller). To implement this a tutorial might be helpful,
where step by step is explained how to send audio data to the line
out/head phone jag and on the other way how to read from the audio line
in/microphone jag (which c-functions are important etc.). Code examples
might be also helpful. What I need first is a code that works with the
audio I/O in the easiest way without special features and code
optimization. I also have tested the swi-, pip- and tsk-audio examples,
but I am missing an explication for the code and its configurations
(DSP/BIOS etc.).

I am looking forward to getting any help.

Thanks a lot

Johannes

Have a look at the books by Rulph Chassaing (Digital Signal Processing and Applications with the C6713 and C6416 DSK), Nasser Kehtarnavaz (Real-Time Digital Signal Processing based on the TMS320C6000) and Welch, Wright and Morrow (Real-Time Digital Signal Processing from MATLAB to C with the TMS320C6x DSK). Each of these does what you want, I think. Regards, Donald

It's been over a year since I've looked at this, but the best result I had was by modifying one of the example projects that came with the C6713 DSK. If I remember correctly, it was the DMA example. I tried the code from the Chassaing book's CD, and while it was useful as a reference I had trouble getting it to build.
