.. zephyr:code-sample:: accel_trig
|
|
:name: Accelerometer trigger
|
|
|
|
Test and debug accelerometer with interrupts.
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample application demonstrates how to use 3-Axis accelerometers with triggers.
|
|
By default it uses a data ready trigger to read the accelerometer data and print it to the console.
|
|
|
|
If the accelerometer is enabled with a tap trigger, the sample uses the tap trigger event to
|
|
read the accelerometer data and print it to the console.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
.. code-block:: devicetree
|
|
|
|
/ {
|
|
aliases {
|
|
accel0 = &fxos8700;
|
|
};
|
|
};
|
|
|
|
Make sure the aliases are in devicetree, then build and run with:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/sensor/accel_trig
|
|
:board: <board to use>
|
|
:goals: build flash
|
|
:compact:
|
|
|
|
With this example, you can also detect a double tap with an accelerometer by activating the
|
|
:kconfig:option:`CONFIG_SAMPLE_TAP_DETECTION`.
|
|
In this example we use a x_nucleo_iks01a3 shield with a LIS2DW12 accelerometer.
|
|
You can build it with the following command:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/sensor/accel_trig
|
|
:board: nrf52dk/nrf52832
|
|
:shield: x_nucleo_iks01a3
|
|
:goals: build
|
|
:west-args: --extra-dtc-overlay x_nucleo_iks01a3.overlay
|
|
:compact:
