How to do it...

You can use I/O loops to read things efficiently in a few steps:

1. Create a binary project: cargo new reading-hardware.
2. Open the folder in VS Code and create a src/sensor.rs file to add the code from the Creating I2C device drivers recipe:

use std::io;use rand::prelude::*;type Result<T> = std::result::Result<T, io::Error>;pub trait Thermometer {    fn temp_celsius(&mut self) -> Result<f32>;}enum Register {    Calib0 = 0x00,    Data = 0x01,}

3. Typically, a raw device abstraction is provided by the hardware protocol drivers used. In our case, we mock up such a type:

#[allow(dead_code)]pub struct RawI2CDeviceMock {    path: String,    device_id: u8,}impl RawI2CDeviceMock {    pub fn new(path: String, device_id: u8) -> RawI2CDeviceMock { RawI2CDeviceMock ...
