ARM CMSIS DSP FFT

Mehran Gomeshlou

Hi
I am using ARM CMSIS DSP FFT library.
Is there any limitations for FFT function to use at sampling rate of 2**14 and above?

Warm regards

    Hi again!
    One thing to add; If I increase the FFT size more than 4096, I get this error from ARM CMSIS STATUS:

    "ARM_MATH_ARGUMENT_ERROR"

    Is it the maximum value that FFT function can handle?
    Is there any other options to increase this number?

    Warm regards
    Mehran
