TMP108

A #[no_std] platform-agnostic driver for the TMP108 temperature sensor using the embedded-hal traits.

The TMP108 can take one of 4 I2C addresses depending on the state of the A0 pin, as described in the table below:

A0	Addr
GND	0x48
V+	0x49
SDA	0x4a
SCL	0x4b

The driver has specific constructors for each of these states, to ensure that an invalid address is not attempted.

Usage

let delay = DelayNs;
let mut tmp = Tmp108::new_with_a0_gnd(i2c, delay);
// let mut tmp = Tmp108::new_with_a0_vplus(i2c, delay);
// let mut tmp = Tmp108::new_with_a0_sda(i2c, delay);
// let mut tmp = Tmp108::new_with_a0_scl(i2c, delay);
// let mut tmp = Tmp108::new(i2c, delay, A0::Gnd);

let cfg = Default::default()
    .with_cm(ConversionMode::OneShot)
    .with_tm(ThermostatMode::Comparator)
    .with_cr(ConversionRate::Hertz16)
    .with_hysteresis(Hysteresis::FourCelsius)
    .with_polarity(Polarity::ActiveLow);

tmp.set_configuration(cfg)?;

let temp = tmp.temperature()?;

let cfg = cfg
    .with_cm(ConversionMode::OneShot)
    .with_tm(ThermostatMode::Interrupt)
    .with_cr(ConversionRate::Hertz1)
    .with_fl(true)
    .with_fh(true);

tmp.set_configuration(cfg)?;

let high_limit = 48.0;
let low_limit = 26.5;

tmp.set_low_limit(low_limit)?;
tmp.set_high_limit(high_limit)?;

tmp.continuous(Default::default(), |t| {
	for _ in 0..10 {
		let temp = tmp.wait_for_temperature()?;
		info!("Temperature {}", temp);
	}

	Ok(())
})?;
