## 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:
|
|
|
|
|
```

|

|
|
|
```
|
|
|

|
##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).
|
|
|
|
|
|
|
|
|
|
When not using irq pin, instead of `USEMODULE = sdp3x_irq`, use `USEMODULE = sdp3x`.
