Question

应用MCS—51定时器T1产生1ms的定时，使P1.3输出周期为2ms的方波，设晶振频率为6MHz，要求工作在方式1来实现
附：TMOD
GATE C/T M1 M0 GATE C/T M1 M0

Answer 1

#include <reg51.h>
#define uchar unsigned char
sbit P2_2=P2^2;

void InitTimer1( )
{
TMOD = 0x10; //定时器1，工作方式1
TH1 = (65536-1000)/256;
TL1 = (65536-1000)%256; //1ms中断一次
EA = 1;
ET1= 1;
TR1 = 1;
}

void main(void)
{
InitTimer1();
while(1);
}
void Timer1Interrupt(void) interrupt 3
{
TH1 = (65536-1000)/256;
TL1= (65536-1000)%256;
P2_2=~P2_2;
}

追问

麻烦你帮我改写成汇编好不谢了

Answer 2

#include "reg51.h"
#define uchar unsigned char
sbit P2_2=P2^2;
//timer init
void initTimer(void)
{
TMOD=0x10;
TH1=0xfe;
TL1=0xc;
}

//timer1/counter1 interrupt
void timer1(void) interrupt3
{
TH1=0xfe;
TL1=0xc;
P2_2=~P2_2;
}

//the main fun
void main(void)
{
initTimer();
TR1=1;
ET1=1;
EA=1;
while(1);
}
