//! A platform agnostic driver to interface the [ST][ST] LPS22
//! pressure sensor, written in Rust. Although the driver is verified
//! using a [`LPS22HH`][LPS22HH] sensor, it should be in theory
//! compatible to other `LPS22` sensors like the [`LPS22HB`][LPS22HB]
//! and if no, it should be easy to make it so.
//!
//! This driver is build using the [embedded-hal][embedded-hal] traits.
