This is a platform agnostic Rust driver for the TMP102 and TMP112
high-accuracy, low-power, digital temperature sensors, using the
embedded-hal traits.
This driver allows you to:
- Change into one-shot or continuous conversion mode.
- Read the temperature.
- Enable/disable the extended measurement mode.
- Trigger a one-shot measurement.
- Read whether the one-shot measurement result is ready.
- Set the conversion rate.
- Set the high/low temperature threshold.
- Set the fault queue.
- Set the alert polarity.
- Set the thermostat mode.
- Read whether a comparator mode alert is active.
This driver is compatible with both the TMP102 device as well as the TMP112 family of devices, including TMP112A, TMP112B and TMP112N.
These temperature sensors are highly linear and do not require complex calculations or lookup tables to derive the temperature. The on-chip 12-bit ADC offers resolutions down to 0.0625°C.
The TMP102 device is a digital temperature sensor ideal for NTC/PTC thermistor replacement where high accuracy is required. The device offers an accuracy of +/-0.5°C without requiring calibration or external component signal conditioning.
The TMP112 family of devices are digital temperature sensors designed for high-accuracy, low-power, NTC/PTC thermistor replacements where high accuracy is required. The TMP112A and TMP112B offers 0.5°C accuracy and are optimized to provide the best PSR performance for 3.3V and 1.8V operation respectively, while TMP112N offers 1°C accuracy.
The devices feature SMBus(TM), two-wire and I2C interface compatibility, and allows up to four devices on one bus.

let mut sensor = Tmp1x2::new(dev, address);
let temperature = sensor.read_temperature().unwrap();
println!("Temperature: {:.1}ºC", temperature);
