Get temperature, and angular velocity data from a BMG160 sensor.

|
|
Overview
|
|
********
|
|
|
|
This sample shows how to use the Zephyr :ref:`sensor` API driver for the
|
|
`Bosch BMG160`_ environmental sensor.

|
|
|
|
The sample first runs in polling mode for 15 seconds, then in trigger mode, display the temperature and angular velocity data from the BMG160 sensor.
|

|
|
Building and Running
|
|
********************
|
|
|
|
The sample can be configured to support BMG160 sensors connected via I2C. Configuration is done via :ref:`devicetree <dt-guide>`. The devicetree
|
|
must have an enabled node with ``compatible = "bosch,bmg160";``. See
|
|
:dtcompatible:`bosch,bmg160` for the devicetree binding and see below for
|
|
examples and common configurations.
|
|
|
|
If the sensor is not built into your board, start by wiring the sensor pins
|
|
according to the connection diagram given in the `BMG160 datasheet`_ at
|
|
page 78.

Sample Output
|
|
=============
|
|
|
|
The sample prints output to the serial console. BMG160 device driver messages
|
|
are also logged. Refer to your board's documentation for information on
|
|
connecting to its serial console.
|
|
|
|
Here is example output for the default application settings, assuming that only
|
|
one BMG160 sensor is connected to the standard Arduino I2C pins:
