Struct BuzzerConfig 

pub struct BuzzerConfig {
    pub frequency: Rate,
    pub duty_pct: u8,
    pub timer_duty: Duty,
}

Configuration for the on-board PWM buzzer (LEDC peripheral, GPIO11).

Controls the pitch and volume of the piezo-electric buzzer. All fields are plain data and can be changed at runtime by reconfiguring the LEDC channel via crate::Buzzer::channel.

Defaults

Field	Default value	Notes
frequency	4 000 Hz	Mid-range buzzer tone.
duty_pct	50 %	Square wave — maximum amplitude.
timer_duty	Duty8Bit	256 steps of duty resolution.

Example

use lilkaoxide::LilkaConfiguration;
use lilkaoxide::cfg::BuzzerConfig;
use esp_hal::time::Rate;
use esp_hal::ledc::timer::config::Duty;

// High-pitched short beep
let beep = BuzzerConfig {
    frequency: Rate::from_hz(2_000),
    duty_pct: 30,
    timer_duty: Duty::Duty8Bit,
};

let config = LilkaConfiguration {
    buzzer_config: beep,
    ..LilkaConfiguration::default()
};

Fields

frequency: Rate

Buzzer frequency in Hz. Audible range for the Lilka piezo: ~500 Hz – 8 000 Hz.

duty_pct: u8

PWM duty cycle 0–100 %. Values above 100 are clamped to 100 internally.

timer_duty: Duty

LEDC timer bit-width. Duty8Bit gives 256 steps and is sufficient for a buzzer.
