stm32f030 rtc闹钟中断我这样配置为什么是一分钟进一次中断？
我想改成5s进一次中断怎么改？求助大神！！！！！！！！！！！！！！！！！！！！！void RTC_AlarmConfig(void)

5秒一次中断用wakeup，下面的代码：
f030 没有你说的那些东西啊。 不好意思，我看的是STM32F0xx_StdPeriph_Lib_V1.5.0的库文件，里面写了有，但是只有072才支持，如果用alarm的话，应该是当前秒+5即可。超过60的%60一下即可。 楼主找到问题没有？我也碰到了同样的问题 安 发表于 2018-4-28 10:46

你好，我使用的是STM32F072CBT6，在工程中查询怎么没有RTC_WKUP_IRQn中断，我需要产生一个7分钟的中断的，可以分享一下你的这块详详细的配置代码吗？ 冷不丁-357544 发表于 2020-9-2 14:11
你好，我使用的是STM32F072CBT6，在工程中查询怎么没有RTC_WKUP_IRQn中断，我需要产生一个7分钟的中断的 ...
您好，这个中断代码是需要自己写的。可以参考官方的例程。 冷不丁-357544 发表于 2020-8-18 10:55

你这个问题解决了吗
