实验报告――多功能万年历

1、单片机实验项目中期报告多功能万年历课程名称： 单片机原理及应用 组 别： 第二十组 小组成员： * 班 级： * 一、 总体设计由于我们实验是在网上购买的现成的开发板来学习和使用的,故在方案的选择上也只能限于开发板设计好的电路和芯片。系统分为主控模块、时钟电路模块、温度检测模块,按键扫描模块，LCD显示模块，电源电路、复位电路、晶振电路等模块。该设计采用 STC89C52 芯片实现 单片机万年历 功能。设计应具有 时间显示 ， 年月日显示 等功能。依据需求可扩展实现 农历显示 功能。运用proteus进行仿真，实现 电路仿真 。运用C语言实现软件相关功能。焊接并完成作品调试。二、 详细设计1、

2、 各模块、元器件的型号及功能主控模块采用AT89C52单片机，STC89C52，ATMEL的51系列单片机。支持串口下载，使用非常方便，且具有很大的价格优势。缺点是仅支持串口下载，不支持在线下载，使用中会有些不方便。按键模块用四个按键，用于调整时间，显示模块采用LCD1602，时钟电路模块采用DS1302时钟芯片实现对时间、日期的操作,温度模块使用18B20实现度温度的操作。2、 流程图3、 软件仿真电路图4、 实物连接图三、 目前实现的功能（录制视频）四、 小组分工情况李彪：连接电路，进行程序的烧写。王进：收集资料，参与相关连接。于红红：程序读写，对实物的介绍。五、 进度安排（截止时间12月

3、23日）项目实验已完成近70%，有些功能还不能实现，有待完善，预计二十号完成。六、 附录（程序）#include /调用单片机头文件#define uchar unsigned char /无符号字符型 宏定义变量范围0255#define uint unsigned int /无符号整型 宏定义变量范围065535#include eeprom52.h#include nongli.hbit flag_200ms ;bit flag_100ms ;sbit beep = P37; /蜂鸣器定义bit flag_beep_en;uint clock_value; /用作闹钟用的sbit dq
