Example

This example shows how to use the FFT class to calculate the fast Fourier transform of a signal to extract the frequencies present in the signal.

Open the example, Files -> Examples -> AmebaAudioCodec -> FFT

Upload the code and press the reset button on Ameba once the upload is finished.

Open the serial monitor, and the output results of the FFT calculation will be displayed.
