Crate led_ring 

LED ring animation engine: spatial patterns + temporal modifiers.

Generic over ring size (N LEDs per ring). Default is 12. No-std compatible, no allocator needed.

Usage

use led_ring::{LedRing, RingAnimation, Rgb, PEDALBOARD_CLOCK_MAP};

// 12-LED ring with pedalboard PCB mapping
let mut ring = LedRing::<12>::new(&PEDALBOARD_CLOCK_MAP);
ring.set(RingAnimation::solid(Rgb::new(255, 0, 0)));
let frame = ring.render(0);
assert!(frame.iter().all(|px| *px == Rgb::new(255, 0, 0)));

Structs

LedRing

Stateful LED ring that tracks animation and renders frames.

Rgb

RGB color (matches smart_leds::RGB8 layout).

RingAnimation

Complete ring animation state.

Enums

Modifier

Temporal modifier — how rendered pixels change over time.

Renderer

Spatial pattern — which LEDs are lit and what color.

Constants

IDENTITY_MAP

Identity clock map for N LEDs (position i maps to physical index i).

PEDALBOARD_CLOCK_MAP

Clock-position mapping for the pedalboard PCB (12 LEDs). PCB layout: D1=3h, D2=2h, …, D12=4h.

Functions

hue_to_rgb

HSV hue (0–255) to RGB at full saturation/value.
