LPS22HH: Temperature and Pressure Monitor

Overview

This sample periodically reads pressure from the LPS22HH MEMS pressure sensor and displays it on the console.

Requirements

This sample uses the LPS22HH sensor controlled using the I2C interface.

Building and Running

This project outputs sensor data to the console. It requires an LPS22HH sensor, which is present on the X-NUCLEO-IKS01A3 shield.
