基于嵌入式系统的按键接口设计技术研究

摘要

嵌入式系统（Embedded system）是指完全嵌入受控器件内部的一种专用的计算机系统。目前嵌入式系统被广泛应用于汽车、摄像机、以及收音机等产品中。然而嵌入式系统按键接口设计多种多样，本文对嵌入式系统的各种按键接口设计技术进行了深入的探讨，详细讨论了数字式按键接口设计技术以及模拟式按键接口设计技术的特点；对按键的反弹和消抖问题进行了深入的探讨。%Embedded system is completely embedded in controlled devices within a dedicated computer system. The embedded system is widely used in automobiles, cameras, radios and other products. However, Button interface design of embedded system are varied. So In this paper, ifrstly the various key interface design of the embedded system technology are discussed in detail, then explores the characteristics of digital button interface design techniques and the analog button interface design techniques. Finally the key rebound and shaking elimination problem has carried on the thorough discussion.
