Blinker

A no_std led blinking library for embedded systems.

Features

• Async/await support
• Configurable blink patterns through Schedule
• Support for both finite and infinite blinking sequences
• No heap allocation (uses heapless Vec)

use blinker::{Blinker, Schedule};
use embassy_time::Duration;
use embedded_hal::digital::StatefulOutputPin;

async fn blink_task(led_pin: impl StatefulOutputPin) {
    let mut blinker = Blinker::<_, 1>::new(led_pin);
    // Blink with 500ms interval
    let _ = blinker.push_schedule(Schedule::Infinite(Duration::from_millis(500)));
    // Run the blink pattern
    loop {
        let _ = blinker.step().await;
    }
}
