关于rtc中断的问题

2502.MspExp430F5137RxUserExperience.c 我的板子是msp-expcc430rf4, 在研究历程是发现如图这段程序， 这是个实时时钟用作定时器？ 我尝试在中断程序中加入led灯反转： P1OUT ^=BIT0; 但是运行后并无反应。 请问这不是定时器吗？ 我也有尝试将//RTCCTL0 |= RTCTEVIE;前的//删去 但是没用。

Susan Yang：

请问您现在使用的是哪个例程？

回复 Susan Yang:

已上传例程.c 谢谢

已上传 谢谢

回复 灰小子:

但是有一个疑问。 我尝试将这段代码中的enable interrupt语句 //注释掉，led灯一样可以闪。这是为何？ 其他几个语句似乎都没有中断允许的。

Susan Yang：

回复 Li Peng:

很高兴您能解决问题

您现在使用的是5137的板子？

我们是有一个RTC的例程的，也是反转P1.0，您可以参考一下
