Rust MCP9808 Driver

This is a platform agnostic Rust driver for the MCP9808, based on the embedded-hal traits.

The Device

The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy.

The device has an I²C interface and user-selectable settings such as Shutdown or low-power modes and the specification of temperature Event and Critical output boundaries.

Details and datasheet: http://www.microchip.com/wwwproducts/en/en556182

Status

Feature complete, but needs more testing.

• temperature register
• configuration register
• resolution register
• manufacturer ID and device ID
• temperature alert upper & lower
• critical temperature

Usage

Assuming you have a reference to the HAL's I2C bus:

    let mut mcp9808 = MCP9808::new(i2c);

    // how to read & write register
    let mut conf = mcp9808.read_configuration().unwrap();
    conf.set_shutdown_mode(ShutdownMode::Shutdown);
    let _c = mcp9808.write_register(conf);
    
    // read temperature register
    let temp = mcp9808.read_temperature().unwrap();
    temp.get_celsius(ResolutionVal::Deg_0_0625C)
