摘　　要：文章介绍一种激光电子教鞭的原理及其实现,该装置采用激光指示鼠标的位置,利用单片机作为中心控制器,采用通用阵列逻辑(GAL)实现光标的定位和按键的捕捉,并通过RS232串口与微机通讯,最终实现对鼠标的控制。为了提高系统的稳定性和可靠性,本系统采用了颇为有效的抗干扰措施。This paper introduces the principle and implementation of a laser-electronic ferule. We use laser to indicate the position of the mouse, and a single chip microcomputer as the central controller. We also use the generic array logic (GAL) to find the position of the cursor and catch the actions of the mouse buttons. To improve the stability and reliability of the system, we have taken anti-interference measures, which have been proved quite effective.
