menuindanpianji.c

单片机在液晶上实现菜单!!!!!!!!!!!

我的硬件:LPC2131+NOKIA5510

 其实这个程序是跟硬件无关的....

一共有两个最重要的文件,其它文件在这两个文件里也有说明.....

 菜单的数据结构就是树...

**文件说明:
 此文件为菜单的实现文件.
 
 1.文件引用说明
  "config.h"      ---系统配置文件
  "MenuFunc.H"    ---菜单中要执行的函数文件
  "MENUDISP.H"    ---菜单图形编码
  "GUI.H"         ---液晶接口
 2.对向输出接口
  Menu_Next(void);
  Menu_Prev(void);
  Menu_Enter(void);
  Menu_Esc(void);
  Menu_Init(void);        
 3.菜单数据结构:
  树.
 4.修改添加菜单依照下面菜单结构.
  见菜单结构中的说明
