生成c51语言代码：1、用Proteus软件画出电路原理图。要求在P1.0至P1.7 口线_上分别接LED0至LED7八个发光二极管，在P3. 0口线 上接---蜂鸣器。 2、编写c51程序:要求LED0至LED7以秒速率循环右移，在灯移动的同时，用定时器和计数器来控制蜂鸣器逐位报警

以下是生成的C51语言代码：

#include <reg52.h>

sbit LED1 = P1^1;

sbit LED3 = P1^3;
sbit LED4 = P1^4;
sbit LED5 = P1^5;
sbit LED6 = P1^6;
sbit LED7 = P1^7;

// 定义蜂鸣器的IO口
sbit buzzer = P3^0;

// 定义计数器和定时器
unsigned int count = 0;
unsigned int timer = 0;

// 定义延时函数
void delay(unsigned int time)
{
    while(time--);
}

// 定义定时器中断函数
void timer0() interrupt 1
{
    TH0 = (65536 - 50000) / 256;
    TL0 = (65536 - 50000) % 256;
    timer++;

    if(timer == 20) // 定时器计数到20
    {
        timer = 0;
        count++;
    }

    if(count == 8) // 计数器计数到8
    {
        count = 0;
    }
}

// 主函数
void main()
{
    TMOD = 0x01; // 设置定时器0为16位自动重装模式
    TH0 = (65536 - 50000) / 256; // 定时器初值
