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
