# About |
||||
This is a manual test application for the LPS331AP pressure sensor driver. |
||||
|
||||
# Usage |
||||
This test application will initialize the pressure sensor with the following parameters: |
||||
- Sampling Rate: 7Hz |
||||
|
||||
After initialization, the sensor reads the pressure and temperature values every 250ms |
||||
and prints them to the STDOUT. |
