@par Example Description
|
|
|
|
How to enter the Stop 2 mode.
|
|
|
|
After start-up LED2 is toggling during 5 seconds, then the system automatically
|
|
enter in Stop 2 mode (Final state).
|
|
|
|
LED2 is used to monitor the system state as follows:
|
|
- LED2 toggling : system in Run mode
|
|
- LED2 off : system in Stop 2 mode
|
|
|
|
This example does not implement a wake-up source from any peripheral: to wake-up the device,
|
|
press on Reset button.
|
|
|
|
@note To measure MCU current consumption on board STM32WL Nucleo,
|
|
board configuration must be applied:
|
|
- remove all jumpers on connector JP8 to avoid leakages between ST-Link circuitry and STM32WL device.
|
|
- remove jumper JP1 and connect an amperemeter to measure current between the 2 connectors of the jumper.
|
|
|
|
@note This example can not be used in DEBUG mode due to the fact
|
|
that the Cortex-M4 core is no longer clocked during low power mode
|
|
so debugging features are disabled.

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32WL55JCIx devices.
|
|
|
|
- This example has been tested with STMicroelectronics NUCLEO-WL55JC RevC
|
|
board and can be easily tailored to any other supported device
|
|
and development board.
|
|
