TC2.0 下定时器使用 DOS
大哥们,小弟想在TC2.0下用定时器,不知道怎么操作?
有前辈写的一下代码,请高手帮忙看下是怎么实现的
#include "main.h"TC 定时器 C语言 Dos
#include "UserType.h"
#include <dos.h>
void interrupt (*oldproc)();
void main()
{
oldproc=getvect(0x1c);
disable();
setvect(0x1c,newproc);
enable();
while (1);
}
void interrupt newproc()
{
printf("111");
}
/***NOTE:
This is an interrupt service routine. You can NOT compile this
program with Test Stack Overflow turned on and get an executable
file which will operate correctly. */
#include <stdio.h>
#include <dos.h>
#include <conio.h>
#define INTR 0X1C /* The clock tick interrupt */
#ifdef __cplusplus
#define __CPPARGS ...
#else
#define __CPPARGS
#endif
void interrupt ( *oldhandler)(__CPPARGS);
int count=0;
void interrupt handler(__CPPARGS)
{
/* increase the global counter */
count++;
/* call the old routine */
oldhandler();
}
int main(void)
{
/* save the old interrupt vector */
oldhandler = getvect(INTR);
/* install the new interrupt handler */
setvect(INTR, handler);
/* loop until the counter exceeds 20 */
while (count < 20)
printf("count is %d\n",count);
/* reset the old interrupt handler */
setvect(INTR, oldhandler);
return 0;
}
