Learn how to sample at up to 500 kHz on the Raspberry Pi Pico and compute a Fast Fourier Transform on captured data
A small gadget that uses an OLED display and the FFT library to generate the audio spectrum. Add a pinch of life to your music.
This is not a full project for a DSO Oscilloscope made with Arduino, but a description of my experiments
Custom 2 GSPS 4K FFT optimized for AMD Versal AI Engine, AI Engine ML, and AI Engine MLv2
The FFTs 4 Fun (FFT4F) library delivers optimized small-size FFTs (8–64 points) for AMD Versal AI Engines
This project uses a microphone analog input, performs an FFT on the data and displays its frequency spectrum to an RGB LED matrix.
