LCD display as a human-computer interaction is very popular in various application situations of embedded microcontroller systems. However, general LCD display menu design is a little bit complicated, and does not have the portability, therefore the complexity in development and system maintenance and the cost are increased. In this paper we introduce the window and message mechanisms of Windows Operating System, and design a multilevel menu. The core of the menu is a universal window engine which does not depend on specific hardware and the content of menu. Research and application show that the menu design has the characters of simple structure, easy to use, little resource consumption, portable and so on. In the end of the paper we present an application example running in the FYD12864 LCD module.%在单片机嵌入式系统的许多应用场合均采用液晶显示器作为人机交互的方式,然而通常的液晶显示菜单设计较为复杂,且基本不具备可移植性,从而增加了开发、维护的复杂性和成本.引入Windows系统下的窗口和消息机制,设计一个多级菜单,该菜单的核心部分是一个不依赖具体硬件和菜单内容的通用的窗口引擎.研究和应用表明,该菜单设计具有结构简单、使用方便、占用资源少以及易于移植等特点.最后给出一个在FYD12864液晶模块上使用此方法的应用案例.
