   新建工程加入 LCD_Lib.c
按照网上  PIC单片机入门教程（四）—— 第一个工程   
https://blog.csdn.net/JYUNefe/article/details/80657918
步骤操作 并进行芯片配置操作
结果 编译 出现错误 大概意思是 LCD_RS 等 引脚没有标识  #include <xc.h>  显示未解析的内部包含文件

思考可能是 什么地方没有设置
请求给予帮助

在头文件中加一个包含PIC16F877A的语句,或者是直接改#define LCD_RS       RD0   这个RD0直接用这个IO的地址,应该是这样的,没有用过C,不知道,你试一下
