Rust LPS25HB pressure sensor driver

Maintenance Intention

A platform agnostic Rust driver for the ST Microelectronics LPS25HB pressure sensor, based on the embedded-hal traits.

Inspired by and partially based on another STMicroelectronics driver.

This driver allows you to:

  • check if sensor is reachable
  • read pressure and temperature
  • set data rate
  • configure interrupts generation
  • configure FIFO

UNDER ACTIVE DEVELOPMENT

Basic functions work, see example. Almost all functions added, and should work fine, but many aren't tested yet.

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:

  • add device ID check and power up in the new() function
  • add an example using FIFO and/or interrupt generation
  • add SPI interface and an example using it
  • add more documentation (main block in the lib.rs)

Some blog post

The device

The LPS25HB 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: LPS25HB

Usage

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

Please find additional examples using hardware in this repository: examples
