摘要
有限状态机作为计算机理论的基石,为嵌入式软件设计提供了较好的设计方法。简述了有限状态机的原理和触摸屏系统的工作原理,通过对触摸屏驱动过程的细致分析,建立触摸屏状态机的模型。针对其状态机模型,选择适合的软件实现方法,并给出部分实现代码。
Finite Automation Machine, as foundation of computer theory,provide a significant powerful way for embedded software design.In this paper,principle of FSM and working mechanism of touch screen are briefly introduced,the model of Touch Screen FSM is built on the basis of close analysis of dirver procedure.
