我有点看不懂你的程序，或许是个人习惯所致，我给你一个我在做RTC时钟用到的中断，你看一下，是如何配置的。 void RTC_It(void) { NVIC_InitTypeDef NVIC_InitStructure; NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1); NVIC_InitStructure.NVIC_IRQChannel = RTC_IRQChannel; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority =6; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); } 可以根据你的需求将RTC_IRQChannel换成自己所需要开通的通道。
