1、 姓名：专业：通信工程 学号：22 成绩：一、实验目的 1.掌握 KeilC51 软件与 Protues 软件联合仿真调试方法；2.掌握 LCM1602 液晶模块显示西文读原理及使用方法；3.掌握用 8 位数据模式驱动 LCM1602 液晶的 C 语言编程方法；4.掌握 LCM1602 液晶模块显示数字的 C 语言编程方法。二、实验内容 1.用 Proteus 设计一 LCM1602 液晶显示接口电路。要求利用 P0 口接LCM1602 液晶的数据端，做 LCM1602 液晶的控制信号输入端。口扩展 4 个功能键 K1K4。2.编写程序，实现字符的静态和动态显示。字符第一行为“1.姓名全拼”，

2、第二行为“专业全拼+学号”。液晶的初始化、字符显示程序可参考网上的程序文件。3.编写程序，利用功能键实现字符的纵向滚动和横向滚动等效果显示。主程序动态显示“My information!”,滚动效果显示四行字符：1：姓名全拼 2.专业全拼+学号 EXP8 三、实验仪器与设备 1.微机一台 c51 集成开发环境 仿真软件 五、实验程序 一、静态显示#include#define uchar unsigned char#define uint unsigned int uchar code table=Dai Haiyang;uchar code table1=tongxin22;sbit lcd
