电子元器件及实用电路设计报告.

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：#includereg52.h#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为中断次数ucharcodelove[]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xFE,0x3F,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x00,0x00,0x00,0x00,0x00,0xF8,0x0F,0x04,0x10,0x02,0x20,0x02,0x20,0x02,0x20,0x02,0x20,0x04,0x10,0xF8,0x0F,0x00,0x00,0x00,0x00,0x00,0x00,0xFE,0x07,0x00,0x08,0x00,0x10,0x00,0x20,0x00,0x20,0x00,0x10,0x00,0x08,0xFE,0x07,0x00,0x00,0x00,0x00,0x00,0x00,0xFE,0x3F,0x82,0x20,0x82,0x20,0x82,0x20,0x82,0x20,0x82,0x20,0x82,0x20,0x82,0x20,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/*LOVE*/};ucharcodeloveyou[]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x78,0x00,0xFC,0x00,0xFE,0x01,0xFE,0x03,0xFE,0x07,0xFE,0x0F,0xFE,0x1F,0xFC,0x3F,0xF8,0x7F,0xFC,0x3F,0xFE,0x1F,0xFE,0x0F,0xFE,0x07,0xFE,0x03,0xFE,0x01,0xFC,0x00,0x78,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/*心形图案*/};ucharcodehehe[]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xC0,0x01,0x40,0x01,0xC0,0x01,0x00,0x00,0x00,0x00,0xF0,0x0F,0x08,0x10,0x04,0x20,0x00,0x00,0x00,0x00,0xF0,0x3F,0x08,0x00,0x04,0x00,0x04,0x00,0x04,0x00,0x08,0x00,0xF0,0x3F,0x00,0x00,0x00,0x00,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x20,0x00,0x00,0x00,0x00,0xF0,0x3F,0x08,0x00,0x04,0x00,0x04,0x00,0x04,0x00,0x08,0x00,0xF0,0x3F,0x00,0x00,0x00,0x00,0x04,0x20,0x08,0x10,0xF0,0x0F,0x00,0x00,0x00,0x00,0xC0,0x01,0x40,0x01,0xC0,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/*呵呵o(∩_∩)o图案*/};unsignedcharcodehanzi[]={//--欢--0x04,0x10,0x34,0x08,0xC4,0x06,0x04,0x01,0xC4,0x82,0x3C,0x8C,0x20,0x40,0x10,0x30,0x0F,0x0C,0xE8,0x03,0x08,0x0C,0x08,0x10,0x28,0x60,0x18,0xC0,0x00,0x40,0x00,0x00,//--迎--0x40,0x00,0x42,0x40,0x44,0x20,0xC8,0x1F,0x00,0x20,0xFC,0x47,0x04,0x42,0x02,0x41,0x82,0x40,0xFC,0x7F,0x04,0x40,0x04,0x42,0x04,0x44,0xFE,0x63,0x04,0x20,0x00,0x00,//--使--0x40,0x00,0x20,0x00,0xF8,0xFF,0x07,0x00,0x04,0x80,0xF4,0x43,0x14,0x45,0x14,0x29,0x14,0x19,0xFF,0x17,0x14,0x21,0x14,0x21,0x14,0x41,0xF6,0xC3,0x04,0x40,0x00,0x00,//--用--0x00,0x80,0x00,0x60,0xFE,0x1F,0x22,0x02,0x22,0x02,0x22,0x02,0x22,0x02,0xFE,0x7F,0x22,0x02,0x22,0x02,0x22,0x42,0x22,0x82,0xFF,0x7F,0x02,0x00,0x00,0x00,0x00,0x00,//--神--0x08,0x01,0x88,0x00,0x49,0x00,0xEE,0xFF,0x58,0x00,0x88,0x00,0x00,0x00,0xF8,0x1F,0x88,0x08,0x88,0x08,0xFF,0xFF,0x88,0x08,0x88,0x08,0xFC,0x1F,0x08,0x00,0x00,0x00,//--奇--0x40,0x00,0x40,0x00,0x44,0x00,0x44,0x3E,0x64,0x12,0x54,0x12,0x4C,0x12,0x47,0x12,0x4C,0x3F,0x54,0x42,0x74,0x80,0xC6,0x7F,0x44,0x00,0x60,0x00,0x40,0x00,0x00,0x00,//--魔--0x00,0x40,0x00,0x30,0xFE,0x8F,0x4A,0x80,0xAA,0x5F,0x9A,0x4A,0xFE,0x2A,0xAA,0x1A,0xCB,0x0F,0xAA,0x7A,0xFE,0x8A,0x9A,0xAA,0xAA,0x8F,0x6B,0x80,0x22,0xE0,0x00,0x00,//--幻--0x80,0x20,0xC0,0x30,0xA0,0x28,0x98,0x24,0x87,0x22,0x80,0x21,0xC4,0x30,0x04,0x60,0x04,0x00,0x04,0x20,0x04,0x40,0x04,0x80,0x04,0x40,0xFE,0x3F,0x04,0x00,0x00,0x00,//--摇--0x10,0x02,0x10,0x42,0x10,0x81,0xFF,0x7F,0x90,0x04,0x54,0x05,0xCC,0xF4,0xB4,0x44,0x84,0x44,0xBC,0x7F,0x82,0x44,0xA2,0x44,0x9B,0xF4,0x82,0x06,0x00,0x04,0x00,0x00,//--摇--0x10,0x02,0x10,0x42,0x10,0x81,0xFF,0x7F,0x90,0x04,0x54,0x05,0xCC,0xF4,0xB4,0x44,0x84,0x44,0xBC,0x7F,0x82,0x44,0xA2,0x44,0x9B,0xF4,0x82,0x06,0x00,0x04,0x00,0x00,//--棒--0x10,0x04,0x10,0x03,0xD0,0x00,0xFF,0xFF,0x90,0x00,0x54,0x05,0x44,0x12,0xD4,0x15,0x74,0x14,0x5F,0xFF,0xD4,0x14,0x54,0x15,0x56,0x12,0x44,0x06,0x40,0x02,0x00,0x00,//--！--0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x7C,0x10,0xFE,0x3B,0xFE,0x3B,0x7C,0x10,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};/*****函数声明*****/voiddisplay1(void);voiddisplay2(void);voiddisplay3(void);voiddisplay4(void);/*****n（us）延时子程序*****/voidDelayUs(uintN){uintx;for(x=0;x=N;x++);}/*****
