Question
Pwr_wakeup
I couldn't able wakeup the system after standby (wakeup should be switching ON mains ) the wakeup pin PA2 is connected to mains pin configured for pwr wakeup.
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */

/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_ADC1_Init();
/* USER CODE BEGIN 2 */
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
/* Enable Power Control clock */
__HAL_RCC_PWR_CLK_ENABLE();
/* Check if the system was resumed from Standby mode */
if (__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET)
{
/* Clear Standby flag */
__HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB);
/* Check and Clear the Wakeup flag */
if (__HAL_PWR_GET_FLAG(PWR_FLAG_WUF4) != RESET)
{
__HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF4);
}
}
