Hi Friends,
Please help me how to sample a signal in frequency domain using PIC16F877A. as like we sample in Matlab giving a input signal and sample.
I need how to frequency sample a signal using PIC 16F877A.
Thnx in Advance
 

are you looking for a FFT implementation with pic ?
 

FFT code i searched and found in https://www.edaboard.com/threads/111741/
but i want how to sample a audio signal usinf microcontroller PIC16F877A
to convert to digital but not considering the magnitude rather using frequency
