这是我自己写的代码，但是调不通，每次都一睡不醒，所以希望大家帮助
- RCC_EnableAPB1PeriphClk(RCC_APB1_PERIPH_PWR, ENABLE);
- RCC_ConfigLse(RCC_LSE_ENABLE);
- while(!RCC_GetFlagStatus(RCC_LSCTRL_FLAG_LSERD));
- RCC_ConfigLSXSEL(RCC_RTCCLK_SRC_LSE);
- RCC_EnableLsi(DISABLE);
- RCC_EnableRtcClk(ENABLE);
- RTC_WaitForSynchro();
- RTC_InitType rtc;
- rtc.RTC_AsynchPrediv = 127;
- rtc.RTC_SynchPrediv = 255;
- rtc.RTC_HourFormat = RTC_24HOUR_FORMAT;
- RTC_Init(&rtc);
- RTC_EnableWakeUp(DISABLE);
- while(!RTC_GetFlagStatus(RTC_FLAG_WTWF));
- RTC_ConfigWakeUpClock(RTC_WKUPCLK_CK_SPRE_16BITS);
- RTC_SetWakeUpCounter(0);
- RTC_EnableWakeUp(ENABLE);
- RTC_ConfigInt(RTC_INT_WUT, ENABLE);
- EXTI_InitType exti;
- exti.EXTI_Line = EXTI_LINE9;
- exti.EXTI_LineCmd = ENABLE;
- exti.EXTI_Mode = EXTI_Mode_Event;
- exti.EXTI_Trigger = EXTI_Trigger_Rising;
- EXTI_InitPeripheral(&exti);
- while(1){
- GPIO_TogglePin(GPIOB, GPIO_PIN_1);
- PWR_EnterSLEEPMode(PWR_SLEEPENTRY_WFE);
- }
