WS2812B Rust Driver (no_std)
A lightweight, platform-agnostic Rust driver for WS2812B RGB LEDs. Designed with embedded systems in mind, this crate provides configurable timing strategies for controlling LED strips using only a data line. Compatible with #![no_std].
✨ Features
- WS2812B-compatible 1-wire RGB protocol
- Multiple timing strategies:
own_delay: Uses an external delay provider implementingDelayNsmanual_delay: Expects delay objects at function callspinloop_delay: Pure spin-loop timing using CPU frequency
- Modular color abstraction via the
Colorstruct - Flexible for boards without advanced peripherals
- Compile-time control via Cargo features
🛠 Configuration
Enable your desired timing backend by activating one of the following features:
| Feature | Description |
|---|---|
own_delay |
Use a mutable reference to a DelayNs trait impl |
manual_delay |
Provide delay at each call to send_color |
spinloop_delay(default) |
Delay through CPU spin-loops with known frequency |
Note: Only one feature should be enabled at a time.
