# `Rust MCP4725 Driver`

> This is a platform agnostic Rust driver for the MCP4725, based on the

[`embedded-hal`](https://github.com/japaric/embedded-hal) traits.

## The Device

The Microchip MCP4725 is a low-power, high accuracy, single channel,

12-bit buffered voltage output Digital-to-Analog Convertor (DAC)

with non-volatile memory (EEPROM).

Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/22039d.pdf

## Status

- [x] Support generation of DAC output using Fast Mode Write Command

- [x] Support writing DAC Input register and EEPROM

- [x] Support RESET command

- [x] Test on Raspberry Pi

## [Examples](examples)

From [`examples/linux_raspi.rs`](examples/linux_raspi.rs):

```rust

extern crate linux_embedded_hal as linux_hal;

extern crate mcp4725_rs;

use linux_hal::{Delay, I2cdev};

use mcp4725_rs::MCP4725;

fn main() {

    println!("Hello, MCP4725!");

    println!();

    println!("Generating sawtooth wave signal on DAC output...");

    let dev = I2cdev::new("/dev/i2c-1").unwrap();

    let address = 0x60;

    let mut dac = MCP4725::new(dev, address, Delay).unwrap();

    

    loop {

        for dac_code in 0..4096 {

            dac.set_dac_value(dac_code);

        }

    }

}

```
