9This sample is a minimum application to demonstrate basic power management
10behavior in a basic blinking LED set up using the :ref:`GPIO API <gpio_api>` in
11low power context.

15Requirements
16************
17
18The board should support enabling PM. For a STM32 based target, it means that
19it should support a clock source alternative to Cortex Systick that can be used
20in core sleep states, as LPTIM (:dtcompatible:`st,stm32-lptim`).

22Building and Running
23********************
24
25Build and flash Blinky as follows, changing ``stm32l562e_dk`` for your board:
26
27.. zephyr-app-commands::
28 :zephyr-app: samples/basic/blinky
29 :board: stm32l562e_dk
30 :goals: build flash
31 :compact:

33After flashing, the LED starts to blink.

35PM configurations
36*****************
37
38By default, :kconfig:option:`CONFIG_PM_DEVICE` and :kconfig:option:`CONFIG_PM_DEVICE_RUNTIME` are
39enabled, but user can also deactivate one or the other to see each configuration
40in play.
