FFT in p24FJ64GA702 using C language

Hello again!
I'm wondering if there exists a good code for FFT implementation in C language for p24FJ64GA702.
I needed the FFT to perform onboard data processing and analyze the frequency component of an array to extract the interested data. I've found a few code examples in C in stackexchange, but i'm not sure if those will be compatible with pic24 devices.
Could someone guide me on that?
thank you very much!!!

    Why would you think standard C code would not work on a PIC24?

    What are the signal parameters?
    What are the FFT parameters?
    PIC24 - poorly suited for DSP.
    Minimum required dsPIC33.
    Butterfly of FFT (fractional) on ASM for dsPIC33 is performed in 23 machine cycles.
