I have an audio in-out program in C for the ADSP-BF706 EZ-KIT mini, about 80 lines in length. It's simple and very easy to understand. It's also completely self-contained - it doesn't use any of the header files that the "TalkThrough_BF706Mini.c" program uses (supplied with the kit). It includes a basic TWI driver, SPORT0 set up and configuration routine for the on board codec (ADAU1761). With some simple modifications it can be used for filtering, both FIR and IIR. The file is attached. All welcome to use free.

Hello Patrick !
That is I need for my first BF706 project on my own dsp board.
Thank you !

Hello Patrick,
your program for the BF706 EZ-Kit Lite is very useful, very clear and it works fine!I have written a DMA and interrupt driven version to avoid polling. This could be a first step to block…
Hello UweS,
I would like to thank you for your code. This is a good example at the beginning of my adventure with DSP and BF706.

I'm trying to use this code from the ADSP-BF706 EZ-KIT, but I'm getting some strange buzzing and a slight ringing with the audio.
I'm attaching some audio files. RawInput: the input to the board.DefaultFilterViaBoard: the filtered input using the code unaltered.NoFilterViaBoard: the input passed through the board after commenting out the code that runs the filter.
What's wrong with my setup that I'm getting these strange additional sounds?Click here to play this audio clipDefaultFilterViaBoard.m4aNoFilterViaBoard.m4a
