单片机控制NOKIA5110液晶屏之模块化编程

这里讲我写的STC12C5A60S2控制洛基亚LCD5110的程序共享一下，是希望前辈们指点。

（补充：以下代码只需要修改lcd5110.h文件中含有 “选择” 字样的部分和字库头文件wordCode.h，就可以达到复用的效果）

测试程序：

#include <reg52.h>
#include "lcd5110.h"
#include "wordCode.h"void main()
{LCD5110Init();//汉字LCD5110AddressWriteWord(0,0,wordcode1[0],16,3,0);        //  每LCD5110AddressWriteWord(2*8,0,wordcode1[0],16,2,1);        //  天LCD5110AddressWriteWord(4*8,0,wordcode1[0],16,2,2);        //  进LCD5110AddressWriteWord(6*8,0,wordcode1[0],16,2,3);        //  步LCD5110AddressWriteWord(8*8,0,wordcode1[0],16,2,4);        //  一LCD5110AddressWriteWord(0,2,wordcode1[0],16,2,5);      //  点LCD5110AddressWriteWord(2*8,2,wordcode1[0],16,2,6);        //  点LCD5110AddressWriteWord(4*8,2,wordcode1[0],16,2,7);        //  就LCD5110AddressWriteWord(6*8,2,wordcode1[0],16,2,8);        //  不LCD5110AddressWriteWord(8*8,2,wordcode1[0],16,2,9);        //  再LCD5110AddressWriteWord(0,4,wordcode1[0],16,2,10);     //  简LCD5110AddressWriteWord(2*8,4,wordcode1[0],16,2,11);   //  单//图片//LCD5110AddressWritePicture(0,0,Pic,42,12,0);while(1);}
