WebThe original EasyFFT function designed to have up to 1028 samples (with the compatible board), while we only need 128 samples. this code reduces memory consumption of around 20% compared to original EasyFFT function. Once FFT is done, the code returns the top 5 most dominant frequency peaks for further analysis. This frequency are arranged in ... WebA simple FFT in written in C, intended for the Arduino. I wrote this to learn writing my own FFT and because the projects I saw out there either had to much extra stuff in them, or were difficult to use and mold to my application. si4732 all band radio receiver review

WebJul 25, 2024 · An FFT lets you decompose a sequence of samples into components of different frequencies, usually into "buckets" that each have a small frequency band. You can then have a look at these buckets to see if there is a peak in a specific frequency range. There are several examples and libraries for this on Arduinos, like EasyFFT and … Webeasyfft.
