STM32 PM Blinky
###############
Overview
********
This sample is a minimum application to demonstrate basic power management
behavior in a basic blinking LED set up using the :ref:`GPIO API <gpio_api>` in
low power context.

Requirements
************
The board should support enabling PM. For a STM32 based target, it means that
it should support a clock source alternative to Cortex Systick that can be used
in core sleep states, as LPTIM (:dtcompatible:`st,stm32-lptim`).
Building and Running
********************
Build and flash Blinky as follows, changing ``stm32l562e_dk`` for your board:
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: stm32l562e_dk
:goals: build flash
:compact:
After flashing, the LED starts to blink.
PM configurations
*****************
By default, :kconfig:`CONFIG_PM_DEVICE` and :kconfig:`CONFIG_PM_DEVICE_RUNTIME` are
enabled, but user can also deactivate one or the other to see each configuration
in play.
