51 单片机实战教程(9 中断库函数)

本文主要是介绍51 单片机实战教程(9 中断库函数)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

STC15W系列单片机最多有21个中断请求源，每个中断请求源都有相应的控制寄存器。要记忆下来是一个比较麻烦的事情，也没有必要。使用时临时去查手册，也比较麻烦费时，一劳永逸的办法是就是写库函数。新建两个文件，分别以stcint.h, stcint.c存入C51 Template文件夹下Library文件夹中。

需要说明的是：中断函数不可以像普通函数那样在头文件中声明，否则编译时会报错。请看下面例子:

/*stcint.h
  Designed by Bill Liu
  Version 0.0 
  Modified last by Bill Liu on 11/29/2021
*/
#ifndef __STCINT_H_
#define __STCINT_H_

#include "mtype.h"
#include "stc15w4k.h"

void STC_Int0(void) interrupt 0;

#endif

/*stcint.c
  Designed by Bill Liu
  Version 0.0 
  Modified last by Bill Liu on 11/29/2021
*/
#include "stcint.h"
void STC_Int0(void) interrupt 0
{
  
}
//End of STC_Int0(void)

/*main.c
  Designed by Bill Liu
  Version 0.0 
  Modified last by Bill Liu on 11/29/2021
*/


#include "main.h" 
#include "stcint.h"

void main()
{
  
  
  while(1)
  {
      
  }
}
//End of main()

编译结果，如下：

编译出错，问题出在中断函数的声明。现在把中断函数的声明注释起来，再看下编译结果：

/*stcint.h
  Designed by Bill Liu
  Version 0.0 
  Modified last by Bill Liu on 11/29/2021
*/
#ifndef __STCINT_H_
#define __STCINT_H_

#include "mtype.h"
#include "stc15w4k.h"

//void STC_Int0(void) interrupt 0;

#endif

编译通过。说明中断函数不用声明,直接在源程序中实现即可。另外需要说明的是，库函数中的中断函数没有实现代码，并被注释起来，需要用时，再去取消注释，添加实现代码，也可Copy到主程序中去实现。库函数主要是中断初始化函数，及中断标志位读写函数。

头文件如下：

/*stcint.h
  Designed by Bill Liu
  Version 0.0 
  Modified last by Bill Liu on 11/29/2021
