Greetings,

I am using a dsPIC33fj (with MPLAB XIDE Xc16 compiler) to sample an analog signal through the ADC with a sampling frequency of 15kHz. I want to pass the signal through FFT function. I have looked into many codes examples or actually the same one which is the code example provided by microchip. I tried to run but its not working for me.


I don't know what is going wrong I'm getting an error that it cant read dspcommon.inc.


Also, I have looked into the code and 'm not sure how can I implement it in my ADC code.


I would really appreciate any help in FFT.
