At present, the monolithic integrated circuit technology39。s application product already entered everyone. The electronic ten thousand calendar39。s appearances have brought conveniently many for people39。s life. This design is one based on STC89C52RC singlechip microputer calendar display system, it can demonstrate years, the month, the date of the Gregorian calendar, and hour, minute, second, temperature, week and so on. Moreover it has also provided the lunar calendar information, adjustable time pattern, temperature sample, alarm system, individual quarterbell and so on. The system clock calendar DS1302 with high performance, low power consumption and simple interface features Circuit enable the system to streamline programming convenience, but also highly functional. The problems of inaccurate, unreliable, and the uniform inferior can be e up when you use the analogous circuit. However, it can be improved when you use the clock system based on STC89C52RC singlechip microputer. The system time accurate, low cost and can be widely applied to the life, study and work in any field, and has played an important role. 4 Key words： The Electronic Calendar Clock, Singlechip Microputer, The Time Calendar Clock, Temperature Chip 5 目錄 ABSTRACT .............................................................................................................................. 3 1 緒論 ........................................................................................................................................ 8 多功能電子萬年歷的研究背景與意義 ...................................................................... 8 多功能電子萬年歷的發(fā)展現(xiàn)狀 .................................................................................. 9 論文研究的內(nèi)容 .......................................................................................................... 9 本設(shè)計進行的主要工作 ........................................................................................... 10 本多功能電子萬年歷系統(tǒng)主要要實現(xiàn)的功能 ........................................................ 10 2 單片 機的簡介 ....................................................................................................................... 11 單片機的介紹 ............................................................................................................ 11 3 方案設(shè)計與論證 .................................................................................................................. 13 單片機芯片設(shè)計與論證 ............................................................................................ 13 電源模塊設(shè)計與論證 ............................................................................................... 14 按鍵控制模塊設(shè)計與論證 ....................................................................................... 14 時鐘模塊設(shè)計與論證 ............................................................................................... 15 溫度采集模塊的設(shè)計與論證 ................................................................................... 15 顯示模塊設(shè)計與論證 ............................................................................................... 15 4 系統(tǒng)的硬件設(shè)計 .................................................................................................................. 17 主控芯片 STC89C52RC 與復(fù)位電路和 時鐘振蕩電路 .......................................... 17 STC89C52RC 的概述 ..................................................................................... 17 復(fù)位電路和 時鐘振蕩電路 ............................................................................. 19 時鐘芯片 DS1302 接口設(shè)計和性能分析 ................................................................ 20 DS1302 性能簡介 ........................................................................................... 20 6 DS1302 接口電路設(shè)計 ................................................................................... 21 溫度芯片 DS18B20 接口設(shè)計和性能分析 ............................................................. 25 DS18B20 的性能介紹 .................................................................................... 25 DS18B20 的接口電路設(shè)計 ............................................................................ 26 鬧鐘模塊系統(tǒng)設(shè)計于性能分析 ............................................................................... 26 AT24C02 器件分析 ......................................................................................... 27 接口電路的設(shè)計 ............................................................................................ 28 LCD 顯示模塊 ........................................................................................................... 28 LCM1602 的特性及使用說明 ....................................................................... 28 LCM1602 與 STC89C52RC 單片機的接口電路 .......................................... 30 按鍵模塊設(shè)計 ........................................................................................................... 31 蜂鳴器設(shè)計 ................................................................................................................ 32 5 軟件設(shè)計 ...................................................................
