摘要

通过分析有限状态机状态转移的特性

提出了利用有限状态机设计液晶显示人机界面的方法。以液晶显示菜单的转换为例

详细论述了使用C语言设计人机界面的过程。使用SPLC501C液晶显示模块实现了菜单的转换功能

且给出了显示菜单转换的液晶显示模块驱动程序。实际应用表明

这种方法易于扩展菜单数量

避免了非法状态的出现

菜单转换迅速、稳定可靠。

Abstract

A method of using finite state machine to design human-machine interface based on liquid crystal is proposed by analyzing the special character of state transition of finite state machine. The paper discusses the process of human-machine interface design in detail by using C language and taking menus transition for example. Menus transition is achieved by using SPLC501C liquid crystal and display driver for menus transition is given. Practice has proved that this method is feasible

easy to extend the number of menu and can avoid the emergence of non illegal states

and the menu transition is very fast

stable and reliable.
