tinytones

tinytones is a #![no_std] Rust crate for defining and playing musical tones and melodies in embedded systems. It provides:

• Enum-based musical pitches from C0 to B8
• Standard and dotted note durations
• Frequency access as u32 or f64
• Iterator for (pitch, duration) tone playback

Predefined tones in the crate

The crate includes a few predefined melodies for convenience:

use tinytones::{Tone, songs::happy_birthday};


let song = Tone::new(happy_birthday::TEMPO, happy_birthday::MELODY);
for (pitch, duration_ms) in song.iter() {
    // Send `pitch.freq_u32()` to a PWM
    // Wait for `duration_ms` using a delay
}

Definiting your own Tone

You can define your own melody using the provided Pitch and Duration enums:

use tinytones::{
    note::{Duration::*, Pitch::*},
    Tone, Melody,
};

let melody = Melody(&[
    (C4, Quarter),
    (D4, Quarter),
    (E4, Half),
]);

let tempo = 120;

let tone = Tone::new(tempo, melody);

for (pitch, duration_ms) in tone.iter() {
    // Send `pitch.freq_u32()` to a PWM
    // Wait for `duration_ms` using a delay
}
