cs43l22-embedded

A Rust crate for interfacing with the CS43L22 DAC on embedded platforms.

Overview

The cs43l22-embedded crate provides a driver for the CS43L22 DAC. Designed for embedded applications, it allows you to initialize, configure, and control the DAC.

Features

Initialization and configuration routines for the CS43L22.
Control functions for audio.
Control over data format
Pretty much everything from the datasheet
Minimal dependencies.

Installation

Add the following to your Cargo.toml file:

[dependencies]
cs43l22-embedded = "1.0.0-alpha"

Usage

Here's a basic example to get started:

// Import the CS43L22 driver
use cs43l22_embedded::Cs43l22;

fn main() {
    // Initialize the driver (adjust parameters as needed)
    let mut cs43l22 = Cs43l22::new(
        &mut i2c_device,
        reset_pin,
        delay_handler,
        cs43l22_embedded::Config::default(),
        cs43l22_embedded::BeepConfig::default(),
        false,
    )
    .unwrap();
    
    // Start audio playback
    cs43l22.play().ok();
    loop{
        // Write pcm audio to the device using I2S
        i2s.write(&audio_buffer);
    }
}

Refer to the crate documentation for the available API methods.

Development

For embedded targets, configure your build environment accordingly. Check the Embedded Book for additional guidance. Or check the examples for the STM32F407G-DISC1 dev board.

Notes

Not everything as been tested so alpha stage until I make sure everything works as expected.
