## About
This is a test application for the SDP3x temperature and differential pressure sensor.

## Usage
This test application will initialize the SDP3x sensor and print TEST_ITERATIONS number
of following values first in continuous mode and then triggered mode every second:

* Temperature
* Differential pressure

The user can specify the number of iterations by setting the variable `TEST_ITERATIONS`
(default value is 10) from commandline as follows:
```
make BOARD=... TEST_ITERATIONS=... -C tests/driver_sdp3x
```

##Features
The sensor has an IRQn pin which indicates data ready on the sensor. This pin can be
connected on the GPIO ports and configured in the variable `SDP3X_PARAM_IRQ_PIN`. This
helps getting measurements as soon as they are ready instead of the 46ms wait (which is
the maximum time the sensor might take the get the measurement ready).
