Hi. Exit from sleep and stop mode not work. When STM32 in sleep mode and push to buttons on pins PA0, PA1, PA2, PA5, PA6, PA7, PA13 (low or high level) STM32 don't exit from sleep mode.

  sleep_counter++;

  if((sleep_counter>=400000)&&(lamp_start==0))

  { 

    GPIO_ResetBits(GPIOF, GPIO_Pin_0);  //A

    GPIO_ResetBits(GPIOF, GPIO_Pin_1);  //B

    GPIO_ResetBits(GPIOA, GPIO_Pin_3);  //C

    GPIO_ResetBits(GPIOB, GPIO_Pin_1);  //D

    GPIO_ResetBits(GPIOA, GPIO_Pin_9);  //E

    GPIO_ResetBits(GPIOA, GPIO_Pin_10);  //F

    GPIO_ResetBits(GPIOA, GPIO_Pin_13);  //G

    GPIO_SetBits(GPIOA, GPIO_Pin_14);  //DP

    

  PWR->CSR = PWR_CSR_EWUP1 | PWR_CSR_EWUP2 | PWR_CSR_EWUP5 | PWR_CSR_EWUP6 | PWR_CSR_EWUP7;

    RTC_AlarmTypeDef  RTC_AlarmStructure;

    RTC_SetAlarm(RTC_Format_BIN, RTC_Alarm_A, &RTC_AlarmStructure);

    RTC_ITConfig(RTC_IT_ALRA, ENABLE);

    RTC_AlarmCmd(RTC_Alarm_A, ENABLE);

    PWR_WakeUpPinCmd(PWR_WakeUpPin_1,ENABLE);

  sleep_counter=0;

  // Clear Wakeup flag 

  PWR->CR |= PWR_CR_CWUF;

  // Select STANDBY mode 

  PWR->CR |= PWR_CR_PDDS;

  // Set SLEEPDEEP bit of Cortex-M0 System Control Register 

  SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;

  // Request Wait For Interrupt 

  __WFI();

  }

Exit from stop mode not work. On low or high level on pins PA0, PA5, PA6, PA7, PA13.

EXTI line is configured.

//CWUF, PDDS and LPDS bits + SLEEPDEEP bit + WFI

PWR->CR |= 0x07;

SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;

__WFI();

How to exit from stop mode by low level on pin PA5.

Sorry, not using the F030 here, may be you can expand your presentation to provide more context to the code, and the board you are using it on?
