Blinksy

Blinksy is a Rust no-std, no-alloc LED control library designed for 1D, 2D, and 3D (audio-reactive) LED setups, inspired by FastLED and WLED.

• Define LED layouts in 1D, 2D, or 3D space
• Choose visual patterns (effects)
• Compute colors for each LED based on its position
• Drive various LED chipsets with each frame of colors

Features

• No-std, No-alloc: Designed to run on embedded targets.
• Layout Abstraction: Define 1D, 2D, or 3D LED positions with shapes (grids, lines, arcs, points, etc).
• Pattern (Effect) Library:
  • Rainbow: Gradual, colorful gradient transition across your layout.
  • Noise: Dynamic noise‑based visuals using noise functions (Perlin, Simplex, OpenSimplex, etc).
  • Make an issue if you want help to port a pattern from FastLED / WLED to Rust!
• Multi‑Chipset Support:
  • APA102
  • WS2812B
  • Make an issue if you want help to support a new chipset!
• Board Support Packages:
  • Gledopto: A great LED controller available on AliExpress: Gledopto GL-C-016WL-D
  • (TODO) QuinLED: The best DIY and pre-assembled LED controller boards
• Desktop Simulation: Run a simulation of a layout and pattern on your computer to experiment with ideas.
• (TODO) Audio-Reactive: Easily integrate audio reactivity into visual patterns.
