Example

use embedded_hal::blocking::i2c;
use mcp9808::{
    temperature::{Celsius, TemperatureMeasurement},
    SlaveAddress, MCP9808,
};

let mut mcp9808 = MCP9808::new(i2c, SlaveAddress::Default);
let measurement: TemperatureMeasurement<Celsius> = mcp9808.read_ambient_temperature().unwrap();
assert_eq!(Celsius(-24.063), measurement.temperature);
