西安交通大学电子系统设计c51单片机数字钟实验

n单片机数字钟实验报告姓名:高航班级：信息43学号：PART 1 实验目的在单片机c51实验板上编程实现2017年日历和实时时钟： 1.时-分-秒（2位-2位-2位）显示； 2.可通过按键置入时间值(参照电子表设置时间工作模式）；3.可通过按键控制在LED上从右向左滚动显示年_月_ 日3次，如：2013_01_20空空2013_01_20 ；4.实现每日闹铃提醒功能，闹铃时间可用按键设置。闹铃采用提示音表示； 5.实现秒表功能； 6.实现定时器功能（预置定时时间，按键启动，倒计时，计到0响提示音； 7.设计实现音乐提示音； 8.能够在短时间按要求修改。PART 2 实验流程图1. 总流程图 2. 设置时间/日期/闹钟模块dis()3. 音乐模块music()PART 3 实验代码代码使用资源：Program Size: data=102.0 xdata=0 code=2420#include#include#define uint unsigned int#define uchar unsigned charuchar t0h,t0l,timeaaa;uchar code FREQH = 0x01, /0的时候没有音符 0xF2, 0xF3, 0xF5, 0xF5, 0xF6, 0xF7, 0xF8, /低音 0xF9, 0xF9, 0xFA, 0xFA, 0xFB, 0xFB, 0xFC, 0xFC,/1,2,3,4,5,6,7,i 0xFC, 0xFD, 0xFD, 0xFD, 0xFD, 0xFE, /高音 0xFE, 0xFE, 0xFE, 0xFE, 0xFE, 0xFE, 0xFF;
