C51程序应用例子,自己的学习历程,希望可以帮到大家

#define uint unsigned int
#define uchar unsigned char
#define ulong unsigned long
#include <reg52.h>

sbit P10=P1^0;

sbit k1=P3^0;


void main(void)
{

RCAP2H=0x10;
RCAP2L=0x00;
TR2=1;
ET2=1;
EA=1;


while (1)
{
;
}

}


timer2() interrupt 5
{
static uchar t;
static uchar s;
TF2=0;
t++;
s++;
if(t==0x1E && s==0x1E)
{
t=0;
P10=~P10;
}

if(s==0x96)
{
t=0;
s=0;
P10=~P10;
}
