RTC闹钟的中断

yinxiangh2020-09-09
有关RTC闹钟的中断,就是要求每一个小时整点产生一次RTC闹钟中断,前几个小时正常,可后面就不产生RTC中断,各位指点下.

  • 唉,还是没有什么结果,算了,多谢大家啦
  • 程序跑飞了 有可能是数据类型的问题
  • 估计是程序哪里跑丢了
  • 应该还是中断配置没对
  • 给你看下,void NVIC_Configuration(void)

    我这里改成10分钟一次.
    本来我要的是1个小时一次中断
  • 楼上好建议,毕竟中断次数太少,每次中断处理结束后再执行一次初始化还是可以的。防止配置失效。
  • 你这样每次中断后,你重新初始化一次这个配置。
  • 肯定是处理中断处理的不对了。
