:name: Generic 3-Axis accelerometer polling
|
|
:relevant-api: sensor_interface
|
|
|
|
Get 3-Axis accelerometer data from a sensor (polling mode).
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample application demonstrates how to use 3-Axis accelerometers.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
This sample supports up to 10 3-Axis accelerometers. Each accelerometer needs
|
|
to be aliased as ``accelN`` where ``N`` goes from ``0`` to ``9``. For example:
|
|
|
|
.. code-block:: devicetree
|
|
|
|
/ {
|
|
aliases {
|
|
accel0 = &lis2dh;
|
|
};
|
|
};
|
|
|
|
Make sure the aliases are in devicetree, then build and run with:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/sensor/accel_polling
|
|
:board: <board to use>
|
|
:goals: build flash
