dear all
I want to impliment 256 points fft on dsPIC33FH64MC802.
I have Microstick Module.

Can anyone help ?

The Microchip C30 compiler comes with a dsp library.
If you look in 'dsp.h' you will find a lot of fft function prototypes that you might be able to use?

I have done the fft on this processor on CCS compiler.
you can use the code from here

for any help , you can ask me .

whereas if you want to do it on the C30 compiler then it is also a good alternative.

I don't think it's the right way to start.
- Try to find some general purpose fft code
- Compile it on your device
- Input a known signal, for instance a sine wave with an
integer number of periods in your interval so that the result should be
2 peaks and 0s elsewhere.
- If there are errors, then you can come back and describe accurately what happens
so that the other users can help you.
