程序完全不对

首先，最后一段程序从

#ifndef _LCD_H_ #define _LCD_H_

开始，它是单独的一个.h文件，如lcd.h

而从

#ifndef LCD1602_4PINS

又应该是一个单独的文件或放在lcd.h的后面，且要定义LCD1602_4PINS

另外

#ifdef uchar

也是错的，应该是

#ifndef uchar

再有main()中更有问题，少头文件，且

LcdWriteData(uchar [i]);

根本也不符合C语法，table，table1定义了没有用

。。。。

你完全还没有入门，先从最基础的程序开始学习下（你上面的涉及工程了，多头文件）
