Real 1D FFT implementations for the k64f?

benledesma — Wed, 12 Apr 2017 17:37:42 GMT

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

Hello Ben L,

- We can run FFT on K64 use KDS, while I don't know whether it can run FFTW and KISS FFT,

I think it mainly depend on if the memory of chip can enough .

- About the FFT , we provide CMSIS lib in KSDK, it includes FFT , there is a example as X.J.Rong

said : What is the most efficient way to perform bulk DMA transfers from the ADC on the K64?

About the SDK download and used , you can refer to here :

Introducing Kinetis SDK v2

Have a great day,
TIC
