fundamental current in pic

i am using pic16f887 and i am digitising ac voltage using built in adc,, now i want to perform fourier analysis on samples , ,can anyone help me how to do?

For a basic PIC that you are using, the input signal would have to be very slow if the PIC has to do a Fourier Transform.
a dsPIC would be better suited.

What compiler are you using? The compiler might have functions to do a running FFT, i.e. when the signal is coming in.

i am using MikroC Pro for PIC v5.8 and i am doing all this to make energy meter, i.e i will give 5VAC on ADC channels and then use digital values to calculate power
