How Blinksy works
- Define your LED
layout in 1D, 2D, or 3D space
- Create your visual
pattern (effect), or choose from our built-in patterns library
- The pattern will compute colors for each LED based on its position
- Setup a
driver to send each frame of colors to your LEDs, using our built-in drivers library.
Features
- No-std, no-alloc: Designed for embedded targets.
- Spatial in 1D, 2D, or 3D: Map out the shape of your LEDs in space.
- Full color support: Supports modern and classic color spaces.
- Global settings: Control overall brightness and color correction.
- Desktop simulation: Simulate your LEDs on your desktop to play with ideas.
- RGB+W support: Supports RGB + White color channels
Multi‑Chipset Support
- clockless: One-wire (only data, no clock)
- WS2812B: Affordable RGB LED, aka NeoPixel
- clocked: Two-wire (data and clock)
- APA102: High-FPS RGB LED, aka DotStar
If you want help to support a new chipset, make an issue!
Pattern (Effect) Library:
- Rainbow: A basic scrolling rainbow
- Noise: A flow through random noise functions.
If you want help to port a pattern from FastLED / WLED to Rust, make an issue!
Board Support Packages
If you want help to support a new target, make an issue!
