Crate rgb_sequencer 

no_std RGB LED animation library for embedded systems.

Provides step-based and function-based color sequences with trait abstractions for LED hardware and timing. Zero heap allocation, platform-independent, type-safe colors via palette::Srgb<f32>.

Core Types

• RgbSequence - Defines an animation (steps, loops, transitions, colors)
• RgbSequencer - Controls a single LED through sequences with state management
• RgbLed - Trait for LED hardware abstraction
• TimeSource - Trait for timing system abstraction
• TransitionStyle - How to animate between colors (Step, Linear, EaseIn/Out)

Color Helpers

• colors module - HSV color space helpers for intuitive color creation

Uses f32 extensively - performance varies by FPU availability.
