I want use the CMSIS-DSP library to calculate the real FFT of a signal, but when I call the FFT functions and I compile in CodeWarrior, the code size exceeds the flash memory.

I´m using a MK20DX128VLH5 with 128kB of flash and my code without FFT function has 6kB.


FFT functions of the library are so great right? Is it correct this?

Don´t have a reduce form of FFT functions to use with Kinetis?
