12864就会一直闪不停，是怎么回事呢？

在下愚笨，实在找不出哪里有问题，但是显示就是不正常，编译无错误无警告。另外，想请教一下，在下的中断有问题吗，为什么开了中断就会出现问题呢。还有，绿色标注的部分如果放进大循环里，12864就会一直闪不停啊，这也不是在下想要的结果啊。因程序稍长，但程序很简单，希望您花几分钟看一下，重点部分红色标注，其余都是一些简单的驱动，下面程序的加热功能区也不需要看。
简单说明一下，在下想要实现的功能。在下打算是用一个部分矩阵键盘和12864在模拟显示个简单太阳能控制器。按键不同，来实现不同的功能选择。用杜邦线引脚的原因是，想来模拟一下水位过低的情况，触发自动上水功能，用中断来模拟上水，每5s，增长一个百分点。大体情况就是这样，如有疑问，随时传唤在下。

简单说明一下，在下想要实现的功能。在下打算是用一个部分矩阵键盘和12864在模拟显示个简单太阳能控制器。按键不同，来实现不同的功能选择。用杜邦线引脚的原因是，想来模拟一下水位过低的情况，触发自动上水功能，用中断来模拟上水，每5s，增长一个百分点。大体情况就是这样，如有疑问，随时传唤在下。
