13Building and Running
14********************
15
16The sample below uses the :ref:`nrf52840dk_nrf52840` and :ref:`nrf52833dk_nrf52833` boards.
17
18To run this sample, ensure the following configurations:
19
20 * Enable one of the Kconfig options:
21 :kconfig:option:`CONFIG_SENSOR_CLOCK_COUNTER`,
22 :kconfig:option:`CONFIG_SENSOR_CLOCK_RTC`, or
23 :kconfig:option:`CONFIG_SENSOR_CLOCK_SYSTEM`.
24
25Build and run the sample with the following command:
26
27.. zephyr-app-commands::
28 :zephyr-app: samples/sensor/clock
29 :board: <board to use>
30 :goals: build flash
