给个单片机液晶1602显示汉字的程序,谢谢

51单片机对lcd1602一些基础程序

#include <intrins.h>

#define dataport P1

sbit RW=P2^5

sbit EN=P2^4

//========================

//=========================

void waitfor() //检测忙信号函数

{

dataport=0xff

RS=0RW=1_nop_() //选择指令寄存器 读 *** 作

EN=1_nop_() //使能 *** 作

while(dataport&0x80) //如果最高位是1 表示1602正忙 原地踏步 忙完后芯片会将高位拉低

EN=0

}

//======================

void writedata(unsigned char dataw) //写数据到lcm

{

waitfor() //测忙

RS=1RW=0_nop_()//选择数据寄存器 写 *** 作

dataport=dataw_nop_()//将数据送到数据口

//==========================

void writecmd(unsigned char cmd) //写命令到lcm

{

}

//===========================

void init(void) // 初始化函数

{

writecmd(0x38)//功能设定 8位数据传输 双行显示

writecmd(0x0c)//显示器开关

writecmd(0x01)//清屏

writecmd(0x06)//字符进入模式 每进入一个字符光标向右移动一格 原有字符不动

//我在刚开始学的时候不知道下一个字符显示在哪 是和AC值有关还是和光标位置有关?

//最后摸索出来是只和光标定位有关 现在还是不知道Ac值有什么用

}

//=========================

void location(unsigned char x,unsigned char y) //确实坐标函数

{

unsigned char temp

temp=x&0x0f //只要x数据的后四位

if(y){temp=temp|0x40} //第一行为0 第二行为1 如果y=1则地址加0x40

temp|=0x80//DDRAM地址的命令DB7为一

writecmd(temp)

}

//==============================

{

location(x,y)

writedata(dataw)

}

//=======================================

}

//=====================================================

while(i--)

{

writedata(*p)

p++

}

//============================================================

location(x,y) //设定要显示的位置

writedata((address&=0x3f)/0x08)//要从CGRAM中读出数据在1602上显示 搞了半天发现CGRAM里的地址

} //和DDRAM里的地址有上面的转换关系

//========================================================

{

unsigned int number[8]

int k,gh

for(k=0k++)

{

//字型码

uchar code nin[]={0x08,0x0f,0x12,0x0f,0x0a,0x1f,0x02,0x02}// "年"
