test.c

忙了很久,,终于找到在Keil 中加入汇编的方法

//#include <C51S.LIB>
#include <reg51.h>
#include <stdio.h>

void main()
{

	P2 = 0x81;
	#pragma asm
	mov p1,#0x02
	MOV p2, 0x11
	#pragma endasm


 /*	  	   #pragma asm
		   clr P1.0
		   mov p0,#0x80
		   #pragma endasm
		   //while(1);
*/

/*		  int k = 0;
		  int m = 0;
		   SCON = 0x52;
		   TMOD = 0x20;
		   TCON = 0x69;
		   TH1  = 0xf3;
		   while(1)
		   {
		   	printf("yes");
			for( k = 0;k<=3222;k++)
			  for(m = 0;m<=56;m++)
			 P0 = ~P0;
		   }

int k = 65530,m,n;
while(1)
{

   P1 = 0x03;
for( m = 0;m<=3000;m++)
	for(n = 0;n<=30;n++);
	 P1 = 0x05;
for( m = 0;m<=3000;m++)
	for(n = 0;n<=30;n++);
 }
