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 !
