I don't know of any official code but I have a little
C demo I made for myself years ago here:
http://www.etantdonnes.com/DATA/FFT.zip
The problem is that the micro-controllers have very
little RAM and no math support beyond an integer
multiply instruction. You can use the above code
to do fixed point calculations which will alleviate
the problems but it's not ideal. It would be better
to do calculations at the host node.
