51单片机代码 在LCD1602上显示HX711的数值

以下是51单片机代码，可以在LCD1602上显示HX711的数值：

#include <reg52.h>
#include <intrins.h>

#define uchar unsigned char
#define uint unsigned int

sbit RS = P2^0; //LCD1602接口定义
sbit RW = P2^1;
sbit EN = P2^2;

uchar code table[] = "Weight: ";

void delay1ms(uint i) //1ms延时函数
{
    uint j, k;
    for (j = i; j > 0; j--)
        for (k = 110; k > 0; k--);
}

void InitLcd() //初始化LCD1602
{
    delay1ms(15);
    sendcmd(0x38);
    delay1ms(5);
    sendcmd(0x38);
    delay1ms(5);
    sendcmd(0x38);
    delay1ms(5);
    sendcmd(0x0C);
    delay1ms(5);
    sendcmd(0x01);
    delay1ms(5);
}

void sendcmd(uchar command) //发送指令到LCD1602
{
    RS = 0;
    RW = 0;
    P0 = command;
    EN = 1;
    _nop_();
    _nop_();
    EN = 0;
}

void senddata(uchar dat) //发送数据到LCD1602
{
    RS = 1;
    RW = 0;
    P0 = dat;
    EN = 1;
    _nop_();
    _nop_();
    EN = 0;
}

void main()
{
    uchar weight[5];
    uint val;
    InitLcd();
    while (1)
    {
        val = read_hx711(); //读取HX711的数值
        val /= 100; //将数值除以100
        weight[4] = val % 10 + '0'; //个位数值
        weight[3] = val / 10 % 10 + '0'; //十位数值
        weight[2] = '.'; //小数点
        weight[1] = val / 100 % 10 + '0'; //百位数值
        weight[0] = ' '; //空格
        sendcmd(0x80); //设置光标位置为第一行第一列
        for (int i = 0; i < 8; i++)
            senddata(table[i]); //显示“Weight:”
        for (int i = 0; i < 5; i++)
            senddata(weight[i]); //显示数值
    }
}

uint read_hx711() //读取HX711的数据并返回数值
{
    uint val = 0;
    uchar i;
    P1 = 0x10; //将PD_SCK置高
    delay1ms(1);
    P1 &= 0xEF; //将PD_SCK置低
    while (DOUT);
    for (i = 0; i < 24; i++)
    {
        P1 = 0x10; //将PD_SCK置高
        val <<= 1;
        delay1ms(1);
        P1 &= 0xEF; //将PD_SCK置低
        if (DOUT)
            val++;
    }
    P1 = 0x10; //将PD_SCK置高
    delay1ms(1);
    P1 &= 0xEF; //将PD_SCK置低
    return val;
}

注意：以上代码仅为示例，需要根据具体的硬件连接和HX711的驱动程序进行修改。
