Hello list. Anyone has it over there some integer FFT routine that fits on a PIC? i was trying to fit on a 16C73 several FFT floating point and integer (all in CCS-C, but all of them didn't work because the lack of ram required for the array and sine/cosine calculations). I'm stuck on this thing, any help, link or a simple suggestion would be greatly appreciated. thanks in advance. see you Leandro -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
