Hi all,
I am wondering if anyone has some ultra-small FFT/DFT routines that will work for discrete data. Speed or accuracy is not an issue, but code size is. If anyone has such routines, in C or Microchip PIC assembly, please post!!!!!! This code needs to run on a PIC 16F877, or for the 18 series PIC, if that helps. Thanks a lot!!!!!!!!
