# Rust LPS22HB pressure sensor driver

A platform agnostic Rust driver for the ST Microelectronics LPS22HB pressure sensor,
based on the [`embedded-hal`] traits.
[`embedded-hal`]: https://github.com/rust-embedded/embedded-hal
Inspired by and partially based on [another STMicroelectronics MEMS driver](https://github.com/lonesometraveler/lsm9ds1).
This driver allows you to:
- read pressure and temperature
- set datarate
- check if sensor is reachable
- enable and configure interrupts
- read data ready and overrun status
- control and configure FIFO
## WORK IN PROGRESS:
This library is work in progress. Not all features are implemented yet. Currently only the I2C interface is implemented. Contributions are welcome.
### TO DO:
- [ ] reference pressure setting
- [ ] add SPI interface
## The device
The LPS22HB is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which communicates through I2C or SPI from the sensing element to the application.
Datasheet: [LPS22HB](https://www.st.com/resource/en/datasheet/dm00140895.pdf)
## Usage
To use this driver, import this crate and an `embedded_hal` implementation,
then instantiate the device.
