1、电子元器件及实用电路设计课程报告组别:十二组组长:吴桥组员:朱冬波、李呈、王伟电路设计一:摇摇棒设计目的:1、了解摇摇棒的工作原理,掌握主要原器件的使用和相关特性;2、掌握焊接工艺的基本技能;3、了解单片机的基本用法以及程序的编写过程4、锻炼基本的焊接电路的能力工作原理:摇摇棒基于51单片机控制、16只高亮度LED发光二极管,很好地利用了人眼的视觉暂留特性,配合手的左右摇晃就可呈现一幅完整的画面,显示字符、图片等。16只LED发光管作为画面每一列的显示,左右摇晃起到了扫描的作用,人眼的视觉暂留现象使得看到的是一幅完整的画面。与LED点阵的显示有
2、几分相仿。系统电源VCC为5V,下载程序和调试时一定要保证5V电压,实际使用时用2节干电池串联6即可。STC89C52单片机作为控制器,在它的P0、P2口接有16只以共阳的方式连接的高亮度LED,由单片机输出低电平点亮。P0口的上拉电阻RA1不能少。串在LED公共端的二极管D1会产生一定的压降,用来保护LED,使两端电压在LED的安全承受范围内。K1是画面切换开关,用于切换显示不同内容;S1为水银开关。水银开关的作用:棒在摇动时,只能在朝某一方向摇动时显示,否则会出现镜像字或镜像画面,所以通过接一只水银开关来控制,使摇摇棒从左向右摇动时将内容显
3、示出来。水银开关里的水银珠很活跃,导致在接通时容易产生抖动,所以将水银开关斜向上放置(尖尖朝斜上方45°角),靠水银珠自身重力的作用减少抖动:电路图:程序设计:#include#defineucharunsignedchar#defineuintunsignedint //宏定义#defineKEYP3_0 //定义画面切换按键ucharKY; //KY作用在后面说明 uchardisp; //显示汉字指针ucharpic="0",num=0; //pic为按键次数;num为中
