.. zephyr:code-sample:: sensor_clock
:name: Sensor Clock
:relevant-api: sensor_interface
Test and debug Sensor Clock functionality.
Overview
********
This sample application demonstrates how to select the sensor clock source
and utilize the Sensor Clock API.
Building and Running
********************
The sample below uses the :zephyr:board:`nrf52840dk` and :zephyr:board:`nrf52833dk` boards.
To run this sample, ensure the following configurations:
* Enable one of the Kconfig options:
:kconfig:option:`CONFIG_SENSOR_CLOCK_COUNTER`,
:kconfig:option:`CONFIG_SENSOR_CLOCK_RTC`, or
:kconfig:option:`CONFIG_SENSOR_CLOCK_SYSTEM`.
Build and run the sample with the following command:
.. zephyr-app-commands::
:zephyr-app: samples/sensor/clock
:board: <board to use>
:goals: build flash
Sample Output
=============
The application will print the current sensor clock cycles and
their corresponding time in nanoseconds.
