51单片机实现万年历程序文件

51单片机实现万年历利用AT89S52单片机的P0口来和另外几个口来控制1602液晶的显示和P1口还有其它口来控制ds12887时钟芯片。

基于51单片机控制的语音报时万年历

基于51单片机控制的语音报时万年历-----20/11/2013 SDU(WH)一．实验要求运用单片机及相关外设实现以下功能：1）万年历及时钟显示2）时间日期可调3）可对时间进行整点报时和随机报时二．方案分析根据实验要求，选用STC公司的8051系列，STC12C5A16S2增强型51单片机。

此单片机功能强大，具有片内EEPROM、1T分频系数、片内ADC转换器等较为实用功能，故选用此款。

实验中，对日期和时间进行显示，显示的字符数较多，故选用12864LCD屏幕。

该屏幕操作较为便捷，外围电路相对简单，实用性较强。

为了实现要求中的时间日期可调，故按键是不可缺少的，所以使用了较多的按键。

一方面，单片机的I/O口较为充足；另一方面，按键较多，选择的余地较大，方便编程控制。

实验中，并未要求对时间和日期进行保存和掉电续运行，所以并未添加EEPROM和DS12C887-RTC芯片。

实际上，对万年历来说，这是较为重要的，但为了方便实现和编程的简单，此处并未添加，而是使用单片机的定时器控制时间，精度有差别。

且上电默认时间为2014-01-01 09:00:00 之后需要手动调整为正确时间。

要求中的语音报时功能，这里选用ISD1760芯片的模块来帮助实现。

此模块通过软件模拟SPI协议控制。

先将所需要的声音片段录入芯片的EEPROM区域，之后读出各段声音的地址段，然后在程序中定义出相应地址予以控制播放哪一声音片段。

2.3.2 时钟电路模块的设计 DS1302 是一种高性能、低功耗、带RAM的实时时钟电路，它可以对年、月、日、周日、
时、分、秒进行计时，具有闰年补偿功能，工作电压为2.5V～5.5V。采用三线接口与CPU进行同步通信，并可采用突发方式一次传送多个字节的时钟信号或RAM数据。DS1302内部有一个31×8的用于临时性存放数据的RAM寄存器。DS1302是DS1202的升级产品，与DS1202兼容，但增加了主电源/后背电源双电源引脚，同时提供了对后背电源进行涓细电流充电的能力。

51单片机实现万年历程序

51单片机实现万年历利用AT89S52单片机的P0口来和另外几个口来控制1602液晶的显示和P1口还有其它口来控制ds12887时钟芯片。

设置四个按键，1个定义为时间设置功能键，一个定义为闹钟设置功能键，另外两个用来调节时间的增减。

硬件部分主要由AT89S51单片机，LED 显示电路，以及调时按键电路等组成。

在单片机的选择上本人使用了AT89S51单片机，该单片机适合于许多较为复杂控制应用场合。

显示器使用2片7SEG-MPX8-CA和一片7SEG-MPX4-CA。

7SEG-MPX8-CA是一种八个共阳二极管显示器，7SEG-MPX4-CA是一种四个共阳二极管显示器。

为了能更轻松的控制这三片显示器，本人使用了3片74HC164来驱动。

74HC164是8位边沿触发式移位寄存器，串行输入数据，然后并行输出。

软件方面主要包括日历程序、时间调整程序，公历转阴历程序，显示程序等。

程序采用汇编语言编写，以便更简单地实现调整时间及阴历显示功能。

单片机课程设计--基于51单片机的万年历

单片机课程设计--基于51单片机的万年历单片机课程设计基于 51 单片机的万年历一、引言在现代生活中，时间的准确记录和显示对于我们的日常生活和工作具有重要意义。

万年历作为一种能够同时显示年、月、日、星期、时、分、秒等信息的设备，给人们带来了极大的便利。

本次课程设计旨在利用 51 单片机实现一个简单实用的万年历系统。

二、系统设计方案（一）硬件设计1、单片机选型选择经典的 51 单片机，如 STC89C52 单片机，其具有性能稳定、价格低廉、资源丰富等优点，能够满足本设计的需求。

2、显示模块采用液晶显示屏（LCD1602）作为显示设备，能够清晰地显示数字和字符信息。

3、时钟芯片选用DS1302 时钟芯片，它可以提供精确的实时时钟数据，包括年、月、日、星期、时、分、秒等。

4、按键模块设置三个按键，分别用于调整时间、选择调整项（年、月、日、时、分、秒等）以及切换显示模式（正常显示和设置模式）。

（二）软件设计1、主程序流程系统初始化后，首先读取 DS1302 中的时间数据，并将其显示在LCD1602 上。

然后进入循环，不断检测按键状态，根据按键操作进行相应的时间调整和显示模式切换。

2、时间读取与显示程序通过与 DS1302 进行通信，读取实时时间数据，并将其转换为适合LCD1602 显示的格式进行显示。

3、按键处理程序检测按键的按下状态，根据不同的按键执行相应的操作，如调整时间、切换显示模式等。

三、硬件电路设计（一）单片机最小系统单片机最小系统包括单片机芯片、晶振电路和复位电路。

晶振电路为单片机提供时钟信号，复位电路用于系统初始化时将单片机的状态恢复到初始值。

（二）显示电路LCD1602 显示屏通过数据总线和控制总线与单片机相连。

数据总线用于传输要显示的数据，控制总线用于控制显示屏的读写操作和显示模式。

（三）时钟电路DS1302 时钟芯片通过串行通信接口与单片机进行通信。

单片机通过发送特定的指令和数据，对 DS1302 进行读写操作，获取或设置时间信息。

基于51单片机的万年历毕业设计

中文摘要本设计万年历以AT89C51为控制中心，与温度传感器DS18B20,时钟芯片DS1302综合应用为一体，不仅能够准确显示时间、日期，闹钟设置，环境温度测量及温度高低温报警等功能。

单片机是一种集CPU、RAM、ROM、I/O接口和中断系统等于一体的器件，只需要外加电源和晶振就可实现对数字信息的处理和控制。

单片机与数字万年历相结合，用于时间显示，温度测试等不仅具有控制方便、组态简单和灵活性大等优点，而且可以大幅度提高被检测数值的技术指标，从而能够大大提高产品的质量和数量。

SCM is a collection of CPU, RAM, ROM, I/O interface and interrupt system is one of the devices, only require additional power can be used for vibration and grain is the process of digital information and control. Single-chip microcomputer and digital calendar, combining for time to show, temperature testing has not only control convenient, simple and flexible configuration advantages, and which could increase the technical index of the tested value, which can greatly improve the quality of the products and quantity.Key words：Single-chip microcomputer, Temperature Sensor,C language，Liquid crystal displ目录第一章前言 (4)1.1系统开发背景及现状 (4)1.2 系统开发的目的 (4)第二章总体设计 (5)2.1 本设计实现的功能和要求 (5)2.2 设计的选择方案和论证 (5)2.2.1单片机芯片的选择方案和论证 (5)2.2.2显示模块选择方案和论证 (5)2.2.3 时钟芯片的选择方案和论证 (6)2.3.4 温度传感器的选择方案与论证 (6)2.3总体设计框图 (6)第三章硬件设计 (7)3.1 主要元器件介绍 (7)3.1.1 单片机简介 (7)3.1.2 传感器DS18B20介绍 (8)3.1.3 LCD1602液晶显示介绍 (9)3.2 各模块设计 (10)3.2.1 主控制电路 (10)3.2.2 LCD1602显示模块设计 (11)3.2.3 DS18B20温度传感器模块 (11)3.2.4 键盘输入模块设计 (12)3.2.5 蜂鸣器模块设计 (12)3.2.6 DS1302时钟电路模块 (13)第四章软件设计 (14)第五章安装与调试 (16)5.1 安装制作 (16)5.2 硬件调试 (16)5.2.1布线的原则与焊接 (16)5.2.2 硬件调试与测试 (17)5.3 软件调试 (17)5.3.1 软件测试仪器 (17)5.3.2 软件调试与测试 (17)5.4 联调 (18)5.5测试结果分析与结论 (19)第六章总结 (20)参考文献 (21)附录A (22)附录B (24)致谢 (26)第一章前言1.1系统开发背景及现状当今世界，知识更新的速度越来越快。

51单片机实现万年历程序文件

51单片机实现万年历利用AT89S52单片机的P0口来和另外几个口来控制1602液晶的显示和P1口还有其它口来控制ds12887时钟芯片。

设置四个按键，1个定义为时间设置功能键，一个定义为闹钟设置功能键，另外两个用来调节时间的增减。

4.能够增长查阅资料的能力，视野更加开阔。

5.拓展其他学科的联系，全面发展。

6.培养自我发现问题，解决问题的能力。

2课程设计的任务与要求2.1设计任务1.可以去学校图书馆或者网上，搜集整理相关的资料，做好前期理论准备，为以后设计电路，看懂电路图做理论支持。

2.构想万年历电路图，并且具有可行性，画出电路图。

3.列举电路所需的电子元件，仔细对比所需的元件的参数，通过去电子元件经销商或者网购购买。

2.2设计要求1.显示年、月、日、时、分、秒。

2.可通过键盘自动调整时间。

3.计时精度：月误差小于20秒。

3单片机发展概况单片机诞生于20世纪70年代末，它的发展史大致可分为三个阶段：第一阶段（1976-1978）：初级单片机微处理阶段。

该时期的单片机具有 8 位CPU，并行 I/O 端口、8 位时序同步计数器，寻址围 4KB，但是没有串行口。

第二阶段（1978-1982）：高性能单片机微机处理阶段，该时期的单片机具有I/O 串行端口，有多级中断处理系统，15 位时序同步技术器，RAM、ROM 容量加大，寻址围可达 64KB。

第三阶段（1982-至今）位单片机微处理改良型及 16 位单片机微处理阶段民用电子产品、计算机系统中的部件控制器、智能仪器仪表、工业测控、网络与通信的职能接口、军工领域、办公自动化、集散控制系统、并行多机处理系统和局域网络系统。

基于MCS-51单片机实现的万年历详细!

摘要本设计是一个基于MCS-51单片机实现的万年历。

本文首先描述系统硬件工作原理，并附以系统结构框图加以说明，着重介绍了本系统所应用的各硬件接口技术和各个接口模块的功能及工作过程,其次，详细阐述了程序的各个模块和实现方法。

本设计以数字集成电路技术为基础，AT89S52单片机技术为核心。

本文编写的主导思想是软、硬件相结合，以硬件为基础，来进行各功能模块的编写。

本系统以单片机的汇编语言进行软件设计，为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了。

系统通过LED显示数据，所以具有人性化的操作和直观的显示效果。

可以显示时间、阳历日期、星期，并有闹铃及检测温度的功能。

This design is based on the digital IC, and the core of AT89C52 MCU technique. This article writed with the guiding of software and hardware unifies, take the hardware as thefoundation, writing each programme for each functions module.This system’s software design whth th e MCU HUIBIAN language, in order to be advantageous for theexpansion and change, the software design uses the design of modularization, so that the logical of the programmer become clear and it is easy to understand .This system LED to show the data，so it has the humanize operation and the intuitionistic show effect. It can show the time, Gregorian calendar, week, bell, pronunciation of time and the temperature examination.Key Words：MCU; DS1302; DS18B20; LED目录摘要......................................................................................................................................I ABSTRACT..........................................................................................................................
