Hi I compiled the code with AVR studio but it gave me 3 compile error. However, they are included in "ffft.h" header file. fft_input(capture, bfly_buff); fft_execute(bfly_buff); fft_output(bfly_buff, spectrum); How do I get the fundamental frequency from the fft code? I basically need to see the ou...

what type of cable do you use for it?

thanx
I used AVR Studio.

What cable are you referring to?
If it is the prgramming cable, I used Atmel AVR ISP MkII on the 6-pin Arduino ISP connector.

Just got the FFT up and running on the Arduino by using AVR Studio.

As an afterthought:

Guess it would be unpractical with all that inline assy.
The ideal would be as an earlier poster asked for: make a stand-alone library for the FFT.

Hope, hope .... :D

Is there an easy way to get the assembly part into the Arduino IDE?

I would like to try getting a spectrum display on the S65 Shield.

Hi,

I would be very interested in getting your complete sample code.
