hmc5883l-rs

Rust library for the HMC5883L magnetometer

This code lets you read x, y, z values from an HMC5883L magnetometer in Rust. This code will only work on Linux platforms and has only been tested on the Raspberry Pi 3.

Usage

```rust let mut mag = HMC5883L::new("/dev/i2c-1", 0x1E).unwrap();

loop { let (x, y, z) = mag.read().unwrap(); println!("x={}, y={}, z={}", x, y, z); thread::sleep(Duration::from_millis(100)); } ```

Wiring

You will need to connect SDA and SCL on the Pi to the corresponding pins on the magnetometer, as well as connecting 3.3V and GND.

Running the example

To run the example:

rust cargo run --example example

You should see output like this. The values will change as your move the magnetometer.

x=498, y=583, z=262 x=478, y=568, z=303 x=451, y=579, z=325 x=454, y=574, z=328
