求一个12864画点简单程序，和一个画图的简单程序，不要教程 要亲测过可以才行。,第1张

//如果只是要话一个点的话简单，这里是个串口程序

#include <reg52h>

#include <intrinsh>

#define uchar unsigned char

#define uint unsigned int

/LCD接口定义/

sbit SID = P1^0; //串行数据

sbit SCLK = P1^1; //串行同步时钟

/汉字地址表/

uchar code addr_tab[]={

0x80,0x81,0x82,0x83,0x84,0x85,0x86,0x87,//第一行汉字位置

0x90,0x91,0x92,0x93,0x94,0x95,0x96,0x97,//第二行汉字位置

0x88,0x89,0x8a,0x8b,0x8c,0x8d,0x8e,0x8f,//第三行汉字位置

0x98,0x99,0x9a,0x9b,0x9c,0x9d,0x9e,0x9f,//第四行汉字位置

};

/n（ms）延时子程序/

void delayms(uint t) //约延时n（ms）

{

uint i;

while(t--)

{

for(i=0;i<125;i++);

}

}

/串行发送一个字节/

void SendByte(uchar Dbyte)

{

uchar i;

for(i=0;i<8;i++)

{

SCLK = 0;

Dbyte=Dbyte<<1; //左移一位

SID = CY; //移出的位给SID

SCLK = 1;

SCLK = 0;

}

}

/写指令/

void Lcd_WriteCmd(uchar Cbyte )

{

//delayms(1);

SendByte(0xf8); //11111,RW(0),RS(0),0

SendByte(0xf0&Cbyte); //高四位

SendByte(0xf0&Cbyte<<4); //低四位(先执行<<)

}

/写数据/

void Lcd_WriteData(uchar Dbyte )

{

//delayms(1);

SendByte(0xfa); //11111,RW(0),RS(1),0

SendByte(0xf0&Dbyte); //高四位

SendByte(0xf0&Dbyte<<4); //低四位(先执行<<)

}

/初始化LCD/

void Lcd_Init(void)

{

delayms(3);

Lcd_WriteCmd(0x30); //选择基本指令集

delayms(1);

Lcd_WriteCmd(0x30); //选择8bit数据流

delayms(1);

Lcd_WriteCmd(0x0c); //开显示(无游标、不反白)

delayms(1);

Lcd_WriteCmd(0x01); //清除显示，并且设定地址指针为00H

delayms(2);

}

void pic_Disp(uchar x,uchar y) //显示一个点

{

Lcd_WriteCmd(0x34); //切换到扩充指令，

Lcd_WriteCmd(0x34);//关闭图形显示

Lcd_WriteCmd(0x80+y); //行地址

Lcd_WriteCmd(0x80+x); //列地址,如果是下半屏这里多加8

Lcd_WriteData(0); //写数据 D15－D8

Lcd_WriteData(1); //写数据 D7－D0

Lcd_WriteCmd(0x36);//打开图形显示

}

void main()

{

Lcd_Init();

pic_Disp(1,1);

while(1);

}
