Hi

I am working on a project ,in which i need to use FFT on 100000 point of input data .I am using CMSIS_DSPLIB_Latest library but it supports only a maximum of 4096 point FFT .So is there any way to find the N point FFT (Where N is Variable length ).

An early response will be appriciated.

Thanks in advance.

If you are asking if NXP has any sort of library or sample code that can do the FFT you are require, then I'm sorry but we do not. Your best bet is to use Google to see if someone has made such a function.
