HC32L136 例程 rtc_int不能进中断

土司Apple 发表于 2022-3-20 11:01

1.背景第一次使用小华的MCU L136，官方例程里面的rtc_int例程，因为我的开发板两个晶振都没有连接所以改用内部晶振
2.代码

3.mcu可以工作，但是RTC的中断不进去，FLAG不能变成1，感觉使用应该挺规矩的吧，不知道那里漏掉了。
4.其它代码都是和DDL库1.9,2一样

CRO->WAIT bit置一后才能修改寄存器吧？

土司Apple 发表于 2022-3-21 09:55

有大神给指导一下不？

例子程序也会有这种错误？该如何修正呢？修改寄存器之前WAIT 写 1么？

华大的手册也是粗制滥造，中国特色。

其实为了安全点，操作RTC寄存器之前应当禁止一切中断为好，完事后开中断。除非你有100%把握中断不影响修改RTC进程。

最后在RTC未启动模式下不用等待WAIT。DDL库的RTCinit上来就关了。应该是正常使用吧

一开始板子焊接不好，之后冲洗焊接了一下，可以了，但是这里的使用感觉还不是很明白，内外部的晶振切换是怎么样的？

土司Apple 发表于 2022-3-31 09:30

开发华大，keil不能用最新的测试 5.29是OK的真是汗流浃背！革命还差的远，请努力呀！

tpgf 发表于 2022-4-3 19:52

开启中断使能了吗

coshi 发表于 2022-4-3 19:55

中断向量重定位？

drer 发表于 2022-4-3 20:10

就是设置寄存器的事

wiba 发表于 2022-4-3 20:21

中断向量被屏蔽了吧

nawu 发表于 2022-4-3 20:33

可以进入其他中断吗

aoyi 发表于 2022-4-3 20:50

产生中断事件了吗
