折腾了 好几周了
现象是:
RTC_WaitForLastTask();
RTC_EnterConfigMode();
RTC_ITConfig(RTC_IT_ALR, ENABLE); //RTC报警中断
RTC_ExitConfigMode();
RTC_WaitForLastTask();
void RTC_ITConfig(u16 RTC_IT, FunctionalState NewState) { /* Check the parameters */ assert_param(IS_RTC_IT(RTC_IT)); assert_param(IS_FUNCTIONAL_STATE(NewState)); printf("here(((((((((((((((((5.11\r\n"); if (NewState != DISABLE) { printf("here(((((((((((((((((5.12\r\n"); //<------------------------------------------------这句有打出 RTC->CRH |= RTC_IT; printf("here(((((((((((((((((5.13\r\n") ;//<------------------------------------------------这句没有打出!!!
} else { RTC->CRH &= (u16)~RTC_IT; } }
求高手帮忙解答下!!!谢谢!!
