MPR Pressure Sensor

Overview

This sample application periodically (1Hz) measures atmospheric pressure in kilopascal. The result is written to the console.

Wiring

This sample uses an MPRLS0025PA00001A sensor controlled using the i2c interface. Connect VIN, GND and Interface: SDA, SCL.

Building and Running

This project outputs sensor data to the console. It requires a sensor from the MPR series. It does not work on QEMU. In the sample below the Arduino Due board is used.
