单片机的1602液晶显示

以上是我认为控制1602液晶比较重要的，必须要我们懂的

下面是我写得到一个程序

#include
<reg51.h>

#define uchar unsigned char

#define uint unsigned int

uchar code table1[]={"I LOVE MCU !"};

uchar code table2[]={"who you name?"};

sbit lcdrs=P2^0; //RS

sbit lcdrw=P2^1;    //R/w

sbit lcden=P2^2; //EN

uchar num,num1,num2;

void delay(uint z)

{

   int x,y;

   for(x=z;x>0;x--)

    for(y=110;y>0;y--);

}

void write_com(uchar com)  //写状态命令函数

{

lcdrs=0;
lcdrw=0;
P0=com;
delay(5);
lcden=1;
delay(5);
lcden=0;

}

void write_data(uchar date)//发送数据函数

{
lcdrs=1;
P0=date;
delay(5);
lcden=1;
delay(5);
lcden=0;

}

void init()

{
lcden=0;
write_com(0x38);
delay(1);
write_com(0x0c);
delay(1);
write_com(0x06);
delay(1);

    // write_com(0x01);
delay(1);
write_com(0x80+0x12);
delay(1);

}

void main()

{
init();
for (num=0;num<12;num++)
{
write_data(table1[num]);
delay(20);
}

     // write_com(0x01); //清屏
write_com(0x80+0x53);
for (num=0;num<13;num++)
{
write_data(table2[num]);
delay(20);
}
for(num=0;num<16;num++)
{
write_com(0x1c);//整屏左移16格 （0x18）右移
delay(200);
}
while(1);

}

这是仿真后的结果
