# About
This is a manual test application for the MPL3115A2 driver.
# Usage
This test application will initialize the MPL3115A2 sensor with the following parameters:
- oversample ratio 128
After initialization, the sensor reads the pressure and temperature values every 1s
and prints them to STDOUT.
