Expand description
This is a platform-agnostic Rust driver for the TMP108 temperature sensor
based on the embedded-hal traits.
For further details of the device architecture and operation, please refer
to the official Datasheet.
§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(())
})?;
