LightSabre

LightSabre is a project designed to control WS281x RGB LEDs using the Secondary Memory Interface (SMI) of a Raspberry Pi, tailored for scenographic and lighting applications.

Features

WS281x LED Control: High-performance driving of addressable RGB LEDs via the Raspberry Pi SMI.
ArtNet Support: Receives color data over the ArtNet protocol, allowing the Raspberry Pi to function as a DMX controller.
Autonomous Mode: Analyzes audio input from an I2S microphone, performing spectral decomposition to generate dynamic lighting effects.
Web Interface: Local web server for configuring and tweaking autonomous behavior.
MIDI Integration: Supports real-time control and parameter adjustment via MIDI controllers.

Technology Stack

Backend: Written in Rust for robust and efficient controller logic. Some low-level operations may be implemented in C or Assembly (to be determined) for optimal performance.
Frontend: Built with Vue.js, providing a modern and responsive web interface for configuration and control.

Use Cases

Stage lighting and scenography
Interactive art installations
Music-synchronized light shows
