13Building and Running
14********************
15
16The sample below uses the :zephyr:board:`nrf52840dk` and :zephyr:board:`nrf52833dk` 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
