专科毕业设计（论文） 基于单片机的摇摇棒设计 摘 要 随着人们物质生活水平的提高，人们对精神生活的追求也愈加强烈，对信息的渴求已成为了人们必不可少的需要，更加简捷与新颖的信息传递方式无疑会给人们带来耳目一新的感受。而现代工具务求简捷化、便携化，因此，摇动显示装置的到来，必将会给人们带来一种新的方便的文化传递方式。 “摇动显示装置”，俗称“摇摇棒”，是基于人的视觉暂留原理的，通过分时刷新16个发光二极管来显示输出文字或图案等信息的显示装置。输出信号频率的控制通过单片机来实现，用水银开关来检测当前摇动状态。当进行摇动时，由于人的视觉暂留原理，会在发光二极管摇动区域产生一个视觉平面，在视觉平面内的二极管通过不同频率的刷新，会在摇动区域内产生图像，从而达到在该视觉平面上传达信息的作用。 本文以单片机的实际应用为背景，介绍了以单片机为核心系统显示设计的基本结构和基本原理。 关键词 单片机/发光二极管/水银开关 Based on single-chip shaking his stick design ABSTRACT As people material standard of living rise, people pursuit to cultural life also becomes strong, the desire of information have become the people of the essential needs, more forthright and novel the information transfer mode will undoubtedly bring people to find everything new and fresh feeling. And modern tools to the simple, portable, therefore, shaking the display device, the arrival of will give people brings a kind of new convenient cultural transfer mode. Shake display device, called to shake the great, it is to be based on visual temporarily leave the principle, through the timeshare refresh 16 leds to display text or design output information display device. The output signal frequency control through the single-chip microcomputer to realize, with mercury switch test current moved state. When shaken, as the mens vision for a principle, will be in the light emitting diode shaking area produce a visual plane, the plane within the vision of different frequency refresh diode through, will produce an image in shaking area, so as to achieve the vision in the plane of conveying information function. Based on the MCU application for background, introduces the single-chip microcomputer and sensor as the core system moved display design the basic structure and the basic principle.
