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

******
|
|
|
|
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 :ref:`arduino_due` board is used.
