1、1/9单片机实训多功能电子时钟的制作一实训的目的：数字的多功能时钟是一种将“时”“分”“秒”显示的视觉器件，它的计时周期为24 小时，显示慢刻度为23 时 59 分 59 秒，因此一个多功能时钟基本电路主要由译码显示器、“时”“分”“秒”计数器。校时电路和震荡器组成。主电路系统由秒信号系统发生“时”“分”“秒”计算器，译码器，及显示器，校时电路组成。秒信号发生器是整个电路的是基信号。它直接决定计时系统的精度，一般用石英晶体震荡器加分频器实现。将标准的秒信号送人“秒”计算器，每累计60 秒发出一分脉冲信号将作为“分”。分钟计数器采用60 进制计数器，时计数器采用 24 进制计数器可实现一天24

2、小时的累计。译码器电路将“时”“分”“秒”计数器的输出状态用七段显示译码器显示。校时电路对“时”“分”“秒”进行调整。二实训的意义：通过此实训在了解基本工作原理的基础上，学会安装调试。使用并学会排除一些电子时钟的常规故障。焊接技术是电子工艺的基本技能之一，通过实训要求大学生初步掌握之一技术的同时，注意培养自己的工作耐心、细心与信心。三实训要求：1.按电路图要求完成硬件电路的焊接调试。2.按电路编程实现时钟的显示、调整、整点提醒、单段/多段定时、秒表等更能。3.采用软件仿真与硬件调试相结合的方法完成作品。四硬件制作：1.所需工具：万用表、镊子、斜口钳、尖嘴钳、电烙铁、剥线钳、平口起子、焊接、松香

3、、元件盒、贴片机、回流焊机等。2.顺序：首先完成仿真电路的调试；按电路图完成硬件电路的安装。3.焊接主意事项：所有元件在使用之前必须测试；主意测出三极管的e、b、c 级，二极管的极性和电解电容正负极；自己核实数码管的每个引脚的功能并测试数码管。2/9#include reg51.h sbit sound=P23;unsigned char code led2=0 x80,0 x40,0 x20,0 x10,0 x08,0 x04,0 x02,0 x01,0 x02,0 x04,0 x08,0 x10,0 x20,0 x40,0 x80,0 x40,0 x20,0 x10,0 x08,0 x04
