基于51单片机的教学打铃控制器的设计毕业设计论文

ements, describes the automatic bell system design approach based on a single chip. System is AT89S51 microcontroller controller DS1302 clock chip to provide time for the system, and on the LCD display, by pressing a button you can set the timer rang the bell and rang the bell time interval. System software design using C language to plish, Easy to use, very convenient for pletion of software design .РKeywords: Belling;AT89S51 microcontroller;DS1302;DisplayР目录Р第一章绪论?1Р1.1 课题背景与来源?1Р1.2 课题意义?1Р1.3 课题设计内容?1Р1.4 本章小结?2Р第二章系统的硬件设计?3Р2.1 系统设计方案?3Р2.2 单片机电路简介?3Р2.3 时钟电路设计?6Р2.4 显示电路设计?8Р2.5 键盘电路设计?8Р2.6 打铃电路设计?9Р2.7 存储器?10Р2.8 温度显示电路?11Р第三章系统软件设计?12Р3.1 软件设计流程图?12Р3.2 读取DS1302时间程序设计?12Р3.4 键盘设定程序设计?15Р3.5 AT24C02?16Р第四章系统调试与测试结果分析?17Р4.1 系统调试?17Р4.2 仿真结果?17Р第五章总结与展望?20Р参考文献?21Р附录?22Р外文资料Р中文译文Р致谢
