arduinoFFT DOI Fast Fourier Transform for Arduino

This is a fork from https://code.google.com/p/makefurt/ which has been abandoned since 2011.

This is version 2.0 of the library, which has a different API.

Tested on Arduino 1.8.19 and 2.3.2.

Installation on Arduino

Use the Arduino Library Manager to install and keep it updated. Just look for arduinoFFT. Only for Arduino 1.5+

Manual installation on Arduino

To install this library, just place this entire folder as a subfolder in your Arduino installation. When installed, this library should look like:

Arduino\libraries\arduinoFFT (this library's folder) Arduino\libraries\arduinoFFT\src\arduinoFFT.h (the library header file. include this in your project) Arduino\libraries\arduinoFFT\keywords.txt (the syntax coloring file) Arduino\libraries\arduinoFFT\Examples (the examples in the "open" menu) Arduino\libraries\arduinoFFT\LICENSE (GPL license file) Arduino\libraries\arduinoFFT\README.md (this file)

Building on Arduino

After this library is installed, you just have to start the Arduino application. You may see a few warning messages as it's built. To use this library in a sketch, go to the Sketch | Import Library menu and select arduinoFFT. This will add a corresponding line to the top of your sketch:

#include <arduinoFFT.h>

API

Documentation was moved to the project's wiki.
