How to do it...

Device drivers can be implemented in a few steps:

1. Create a binary project: cargo new i2cdevice-drivers
2. Open the folder in VS Code and add some code to the src/main.rs file to:

mod sensor;use sensor::{Bmx42Device, RawI2CDeviceMock, Thermometer};use std::thread::sleep;use std::time::Duration;fn main() {    let mut device = Bmx42Device::new(RawI2CDeviceMock::     new("/dev/i2c-1".into(), 0x5f)).unwrap();    let pause = Duration::from_secs(1);    loop {        println!("Current temperature {} °C",          device.temp_celsius().unwrap());        sleep(pause);    }}

3. Next, we are going to implement the actual sensor driver. Create a file named src/sensor.rs to implement all aspects of the sensor driver. Let's start by setting up a few basics:

use std::io;use rand::prelude::*; ...
