8C芯片，ET2未定义的情况，请教一下
如题，程序是以前写的，用的8C的芯片，一直都在正常用，正常改写。就今天忽然改写一处小参数后，发现再编译时，提示：
: error C202: 'ET2': undefined identifier
又打开别的正常一直用的程序，再编译还是出现这个提示，程序前的头文件如下：
#include"STC8C.H"
#include<intrins.h> // _nop_();
#define WT_12M 0x83 //测试工作频率为12MHz
应该是头文件里没有ET2的定义吧，请教一下大家，为什么会突然出现这种情况，
PS:电脑近期没有做过改动，一直正常在用

这样重新生成了头文件，但是没有解决这个问题，很是奇怪 没有 ET2的定义，自己用其他方式代替 神农鼎 发表于 2024-7-7 18:05
没有 ET2的定义，自己用其他方式代替
就是实在想不明白这些程序都是以前正常用的，忽然出现这个情况，我第一怀疑就是头文件出问题了，再重新生成时，就是找不到这个ET2
神农鼎 发表于 2024-7-7 18:05
没有 ET2的定义，自己用其他方式代替
请教一下，用什么方式代替？自己在头文件里加一句吗？
我特意把STC8C的头文件搞下来看了一下，如你所说，没有ET2
但是你得明白在8C里ET2是干嘛的，对不？
这时候我凭经验看，是定时器2的使能，不就是允许/禁止定时器2的中断嘛，因为Enable Timer2，缩写为ET2。
但做技术不允许猜测，所以我就继续帮你看。
我没用过8C，为了回答这个问题，我就得看8C的手册{:4_165:}
然后在手册里找到了ET2的说明
属于IE2，中断允许寄存器2。
然后我继续往下看
所以，到这里，你就有办法了啊。
甭管头文件有没有，你想用，还不想或不会修改头文件（当然，一般建议不要改，听说离职的工程师会在离职前瞎改，哈哈，开个玩笑）
那法子不就来了嘛
IE2 |= 0x04;
这不就把ET2单独进行了一次赋值为1嘛。
到这里其实已经可以算结束了，但是你可以在未来不断提高的路上，让别人知道你这一步是做什么，增强一下程序的可读性，
那就在前面宏定义#define ET2 0x04
然后在定时器2的允许时，把IE2 |= 0x04;换成IE2 |= ET2；这样不仅能实现，还能知道你是做什么。
这是一种方法，
另外一种就是常用的一种移位操作，也能提高程序的可读性。
IE2 |= (2<<1);//通过移位操作实现
现在相当于是3种方式来表达同一个东西，但万变不离其宗，你只是在操作ET2，却有好几种方式去实现。
玩的花了，见笑。{:4_183:}
感觉已经相当于发了一个帖子了。神农鼎前辈怎么看，哈哈。

我特意把STC8C的头文件搞下来看了一下，如你所说，没有ET2
以前头文件中有做了 ET2的宏定义，后来有些新人不理解 ET2 这个宏定义，
并且还批评其他的一些技巧，我们同事说，有人反对头文件的高级技巧，
那就去掉这些吧，说头文件就是头文件，不要用高级技巧太多了
===就是很多建议都有道理，选择支持哪种建议而已
这ET2的宏定义去掉的事我是知到的，头文件从优秀回到了入门级
以前实验箱的例程也是用了很多编程技巧，后来也简化了，
部分老师说，同学们 C 还没懂，又上这么多宏，
增加理解难度了
如下技巧都增加了初学者的理解难度
