Ameba Arduino: Audio Codec - FFT

Materials

• AmebaD [RTL8722DM / RTL8722CSM / RTL8722DM MINI] x 1

Example

Introduction
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.

Procedure
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.
