I have had a few people ask for the CAD files and software for the ADAU1442 DSP. I have tried uploading the whole lot as a series of ZIP files - I hope this works OK.

There are a few things that warrant comment, and if you try to untangle this lot, I am sure a few questions to me. Feel free to ask away...

Comments:
- The sigmastudio file is simply there to generate the code for the DSP. All the actual values for filters etc are calculated by the microcontroller under user control.

- SigmaStdio generates a bunch of export files, my software uses the *.h files, both to load the DSP code, and also to get the addresses in the ADAU1442 of registers for biquad coefficients etc. The microcontroller code pretty well loads these in straight, but there is a tiny bit of tidying up the sigma generated files first...

- The microcontroller is a PIC18F4560 (from memory) the CAD file has a PIC18F5420 in the schematic - these are pin...
