FastLED is a C++ library for driving pixel-addressable LED chipsets and strips across various microcontroller platforms. It functions as an addressable LED control library and driver abstraction layer that converts color data into specific electrical timing for different hardware protocols. The project includes an audio-reactive visual engine for translating real-time beats and frequency data into synchronized animations, alongside a microcontroller math library optimized for high frame rates.
The system provides a unified interface for managing various clockless and SPI LED chipsets. It distinguishes itself through performance optimizations such as LED signal overclocking, parallel strip driving, and signal timing adjustments to increase data refresh rates.
The library incorporates an HSV color management system for color space conversion and gamma correction to ensure smooth brightness transitions. It also covers animation layer composition, spatial visual effects, and global brightness control to manage power consumption.
