1、专业综合课程设计报告题目：智能电子钟（ LCD ）班 级： 1121 应用电子姓名（学号）：游政园 2011212150题目智能电子钟(LCD )设计要求：制作一个LCD显示的智能电子钟：(1) 计时：秒、分、时、日、月、年、星期。(2) 闰年自动判别。(3) 时间、年、月、日、星期交替显示。自定任意时刻自动开/关屏。(6)计时精度：误差w 1秒/月(具有微调设置)本实验可采用并行时钟芯片(DS12C887和串行时钟芯片(DS1302), DS302要用户自己安装后备电池和串口通讯，要 32.768KHZ的晶振，而 DS12C887自带后备电池，并口通讯，无需外围元件，并且DS12C887多了

2、一个字节来记录世纪使用的，处在 RAM的32H单元，但是其他的寄存 器定义都相同。由于本实验用到了 STC12C5A60S直插 40P封装的单片机、 nokia5110液晶屏、独立式按键、四路 2输入与门并且都是直插的，而 且在实验室做PCB只能是单层板，为了节约空间和简化电路于是就选用 了串行时钟芯片DS1302理论设计：用CAD软件绘制的硬件原理图DOWIN 口适用于四角插针式下载、BAT为备用电源端口不仅运行速度快稳定驱动能力更大， 还为用户提供了内部集成8位/10位可调分 辨率ADC模块（在此设计中有用到），1KB可擦写EEPRO本设计中用其设计成可 调闹钟功能存放闹钟值。wuLCDB
