| 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. |
| |
| .. _stm32-pm-blinky-sample-requirements: |
| |
| 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:option:`CONFIG_PM_DEVICE` and :kconfig:option:`CONFIG_PM_DEVICE_RUNTIME` are |
| enabled, but user can also deactivate one or the other to see each configuration |
| in play. |
