An efficient way to implement FFT using Arduino
This is not a full project for a DSO Oscilloscope made with Arduino, but a description of my experiments
Fully pipelined implementation of FFT with fixed-point arithmetic in Vitis HLS
A simple yet effective demonstrator of a gear pump endorsed with Arduino Nano + MPU6050 accelerometer to measure vibrations.
A 32-channel RGB audio spectrum analyzer / visualizer driven by teensy 3.2 with FFT using WS2812B 32x8 RGB LED
Custom 2 GSPS 4K FFT optimized for AMD Versal AI Engine, AI Engine ML, and AI Engine MLv2
Not yet another spectrum analyzer — an experimental DSP & graphics playground. It combines real-time C++ performance with Python flexibility
In this project, a robot's movement is controlled by a fast Fourier transform and its reading of various frequencies and beats.
Using a TI F28379D Launchpad and a plastic recorder we coded a robot to move. Using WiFi an ESP8266 sent the notes to LABView on a computer.
