Hello Ali,

To enter Stop mode you need to :

  • configure the bits LPMS(Low Power Mode Selection) in PWR_CR1 register to select the power mode
  • Set SLEEPDEEP bit of Cortex System Control Register
  • request for WFI or WFE

Or you can simply go to the example of the STM32Cube_FW_L4_V1.14.0 under this path : " STM32Cube\Repository\STM32Cube_FW_L4_V1.14.0\Projects\NUCLEO-L476RG\Examples\PWR\PWR_STOP2\ ".

You can download it from here

Best Regards,

Mohamed Aymen.
