Symphony SoundBite Development Kit

[tekajay]

Hi,

I've recently been handed a project and was asked to build it on the Symphony SoundBite Development Kit. The Kit has the DSP56371 Processor. I have gone through a few tutorials and gotten a brief idea of building projects and debugging them.

However, for my project I have to input samples from the microphone, process it and finally output the samples to the speakers. For this I need to know the C - command and syntax for inputting and outputting the samples. Also I need to know how to set the Sampling Frequency of the Codec in the C-source code.

Could someone help by pointing me in the right direction where to look or if you have the answers, that would be great.

Thanks,

Ajay

Hi,

you can start with my sample project:

With C is difficult to optimize signal processing routine in dsp56xxx, I think you need to write some asm code.

Let me know if you have problems with my code.
