Crate esp_hal_buzzer 

Buzzer

Overview

This driver provides an abstraction over LEDC to drive a piezo-electric buzzer through a user-friendly API.

The buzzer example contains pre-programmed songs to play through the buzzer.

Example

let peripherals = esp_hal::init(esp_hal::Config::default());

let mut ledc = Ledc::new(peripherals.LEDC);
ledc.set_global_slow_clock(LSGlobalClkSource::APBClk);

let mut buzzer = Buzzer::new(
    &ledc,
    timer::Number::Timer0,
    channel::Number::Channel1,
    peripherals.GPIO4,
);

// Play a 1000Hz frequency
buzzer.play(1000).unwrap()
