Real 1D FFT implementations for the k64f?

Hi folks,


  I'm looking for a simple FFT algorithm which will take in real one-dimensional arrays of size 2^n and output an array of frequency amplitudes. I am using a k64f board and a processor expert project through kinetis design studio.


  Currently I have attempted to implement the algorithm found in here. The first half of the code works as written, but I have had issues getting the second half to work. I have also found FFTW and KISS FFT, but am unsure that either may be used with my choice of compiler.


Thank you for your help,


Ben L
