我想要在LCD1602显示当前电流值

好的，你可以使用51单片机的另一个IO口连接LCD1602，通过LCD1602显示当前电流值。以下是修改后的代码：

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

#define ADC0832_DATA P0
#define ADC0832_CS P1_0
#define ADC0832_CLK P1_1

sbit LED = P2_0; //定义LED指示灯

sbit RS = P2_6; //LCD1602的RS引脚
sbit RW = P2_5; //LCD1602的RW引脚
sbit E = P2_7; //LCD1602的E引脚

void delay(int time) //延时函数
{
    int i, j;
    for(i = time; i > 0; i--)
        for(j = 110; j > 0; j--);
}

void initADC0832() //初始化ADC0832
{
    ADC0832_CS = 1; //片选禁止
    ADC0832_CLK = 0; //时钟置0
}

unsigned char getADC0832Data() //获取ADC0832数据
{
    unsigned char i, result = 0;
    ADC0832_CS = 0; //片选使能
    _nop_(); //空操作
    _nop_();
    _nop_();
    for(i = 0; i < 8; i++)
    {
        ADC0832_CLK = 1; //时钟置1
        _nop_();
        _nop_();
        _nop_();
        result <<= 1; //左移一位
        result |= ADC0832_DATA; //读取数据
        ADC0832_CLK = 0; //时钟置0
    }
    ADC0832_CS = 1; //片选禁止
    return result; //返回结果
}

void writeCommand(unsigned char command) //写指令函数
{
    RS = 0; //将RS置0
    RW = 0; //将RW置0
    E = 1; //将E置1
    P0 = command; //将指令写入P0口
    E = 0; //将E置0
    delay(5); //延时5毫秒
}

void writeData(unsigned char data) //写数据函数
{
    RS = 1; //将RS置1
    RW = 0; //将RW置0
    E = 1; //将E置1
    P0 = data; //将数据写入P0口
    E = 0; //将E置0
    delay(5); //延时5毫秒
}

void initLCD1602() //初始化LCD1602
{
    writeCommand(0x38); //设置显示模式为16x2、5x7点阵、8位数据
    writeCommand(0x0c); //设置显示开关、光标开关、光标闪烁开关，显示开，光标和闪烁关闭
    writeCommand(0x06); //设置字符输入方式为左移，不移动屏幕
    writeCommand(0x01); //清屏
}

void displayCurrent(unsigned char current) //显示当前电流值
{
    unsigned char high = current / 100; //计算百位数
    unsigned char mid = (current % 100) / 10; //计算十位数
    unsigned char low = current % 10; //计算个位数
    writeCommand(0x80); //将光标移动到第一行第一列
    writeData('C'); //显示'C'
    writeData('u'); //显示'u'
    writeData('r'); //显示'r'
    writeData('r'); //显示'r'
    writeData('e'); //显示'e'
    writeData('n'); //显示'n'
    writeData('t'); //显示't'
    writeData(':'); //显示':'
    writeData(high + '0'); //显示百位数
    writeData(mid + '0'); //显示十位数
    writeData(low + '0'); //显示个位数
}

void main()
{
    unsigned char adcData = 128; //设置初始电流值为一半
    initADC0832(); //初始化ADC0832
    initLCD1602(); //初始化LCD1602
    while(1)
    {
        adcData = getADC0832Data(); //获取ADC0832数据
        if(adcData > 127) //判断ADC0832输出电流是否大于一半
            LED = 1; //LED指示灯亮
        else
            LED = 0; //LED指示灯灭
        displayCurrent(adcData); //显示当前电流值
        delay(100); //延时100毫秒
    }
}

在`displayCurrent`函数中，首先计算出电流值的百位、十位和个位数，然后依次将它们显示在LCD1602上。需要注意的是，在每次显示电流值之前，需要先将LCD1602清屏，否则会出现残留的字符。
