Rust LPS22HB pressure sensor driver

Maintenance Intention

A platform agnostic Rust driver for the ST Microelectronics LPS22HB pressure sensor, based on the embedded-hal traits.

Inspired by and partially based on another STMicroelectronics MEMS driver.

This driver allows you to:

  • read pressure and temperature
  • check if sensor is reachable

WORK IN PROGRESS:

This library is work in progress. Not all features are implemented yet. Contributions are welcome.

TO DO:

  • output data rate setting
  • interrupts configuration
  • FIFO configuration
  • reading reference pressure
  • calibration
  • reading data ready status
  • reading data overrun status

Some blog post

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

Usage

To use this driver, import this crate and an embedded_hal implementation, then instantiate the device.
