51单片机课程设计（DS1302时钟、18B20温度计）

摘要: 该设计实现了24小时制的时间显示及设定、年月日星期的显示及设定、闹钟的设定、温度的检测及显示等功能。

设计共分为四大部分，分别是控制部分、时钟部分、温度检测部分和人机交互部分。

以单片机（A T89C51）组成的最小系统为整个设计的控制核心，单片机通过对时钟芯片（DS1302）的控制完成时钟的功能，通过对温度传感器（18B20）的控制完成温度检测的功能，最后通过对数码管、蜂鸣器及按键的控制完成时间和温度的显示以及调整时间、设定闹钟等功能。

时间和温度的显示以及调整时间、设定闹钟等功能。

单片机12864LCD、DS1302、DS18B20

用汇编写了那么多程序，马上就要用C了，所以做一个我近期在单片机上用汇编写代码的心得和一些自认为有用的程序。

主要是近期自学过的模块，比如protues中的AMPIRE128X64—LCD，DS18B20—温度测量模块，DS1302—时钟芯片。

好啦，废话也不多说了，注意我是按照我写程序的规范来写的，不过很容易理解，我也希望能帮助更多的单片机爱好者。

AMPIRE128X64一、Protues上LCD与单片机相连如图：二、打开keil新建一个AT89C51单片机的工程。

建立如下工程12864.A51用于存放驱动程序，方便调用。

main.a51用于存放主程序。

如果想知道这款LCD的详细信息可去百度文库搜索。

三、以下是12864.A51内的驱动程序，有详细解说。

基于DS1302和DS18B20设计的多功能电子实时时钟

基于DS1302和DS18B20设计的多功能电子实时时钟摘要随着电子技术的迅速发展，特别是随大规模集成电路出现，给人类生活带来了根本性的改变。

尤其是单片机技术的应用产品已经走进了千家万户。

电子日历的出现给人们的生活带来的诸多方便。

本设计介绍了一种在数码管屏幕上显示当前日期时间和温度的51单片机控制系统。

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过程。

本设计以数字集成电路技术为基础，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C语言进行软件设计，增加了程序的可读性和可移植性,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8位数码管为载体显示数据，所以具有人性化的操作和美观的效果。

可以自动显示年月日、星期、温度等。

设计中处理器选取内核为C51的STC89C52单片机；数字温度传感器DS18B20，作为单片机外部信号源，实时显示温度；时钟芯片DS1302提供当前日期和时间数据；实时的日期和时间及温度数据在数码管上显示。

在显示部分，利用3/8译码芯片74HC138控制8位数码管的位选，利用串入并出的芯片74HC164来驱动8位数码管的段码,节省了主控芯片的I/O口。

这种实时时钟不仅具有一般时钟的显示时分秒功能，还能显示月日周，而且能显示当前的实时温度，另外仅使用三个按键调时，简单方便易于使用。

实践证明该系统稳定性高，显示数据准确。

摘要本文借助电路仿真软件Protues对基于STC90C516RD+单片机的电子万年历的设计方法及下载测试进行了全面的阐述。

该电子万年历在硬件方面主要采用STC90C516RD+单片机作为主控核心，由DS1302时钟芯片提供时钟、12864点阵液晶显示屏显示。

STC90C516RD+单片机是由Atmel公司推出的，功耗小，电压可选用4～6V电压供电；DS1302时钟芯片是美国DALLAS公司推出的具有涓细电流充电功能的低功耗实时时钟芯片，它可以对年、月、日、星期、时、分、秒进行计时，还具有闰年补偿等多种功能，而且DS1302的使用寿命长，误差小；数字显示是采用的LED液晶显示屏来显示，可以同时显示年、月、日、星期、时、分、秒等信息。

此外，该电子万年历还具有时间校准等功能。

在软件方面，主要包括日历程序、时间调整程序，显示程序等。

所有程序编写完成后，在Keil软件中进行调试，确定没有问题后，进行下载调试。

论文主要研究了液晶显示器及时钟芯片DS1302，温度传感器DS18B20与单片机之间的硬件相互之间通信，对数种硬件连接方案进行了详尽的比较，在软件方面对日历算法也进行了论述。

LCD12864液晶屏-DS1302时钟日历-DS18B20测温度智能消毒擦鞋鞋柜C程序

一个能消毒、烘干、擦鞋的智能鞋柜控制器，LCD12864显示菜单，像塞班手机那样，过会儿无按键操作屏幕背景灯变暗，用的是有字库的屏，因为显示了图片，在清屏时图片和字库的命令有冲突，后来干脆汉字也用字模软件取的，因为我是新手，学习方向也不在屏上，就没花太多时间研究图片和字库里的字同时清屏，DS1302显示时间，掉电存储运行状态，这个芯片不很精确，过阵子需要手动对时间，DS18B20测温度，单片机用的STC12C5A60S2，菜单图片都要存到单片机里就用了个大容量的，外中断0接红外对射开关，用于检测是否有脚伸到擦鞋机下面，是否启动擦鞋机电机。

功能很简单，知识点主要涉及LCD1286D 的打点、菜单显示，DS1302的EEPROM存储、日期运算等，没写H文件，都在main程序，没看门狗，没通信，基本的入门的东西，就是有点长，给各位有需要的分享下，程序写的不好，但是肯定能用，给个财富值吧，我都经常下别人的东西三五个下载券，都没分了，正郁闷呢。

下面上程序，带软开关的，其实软开关也不是这样做的，我只是想实现下能按了开关才启动的这个动作，要是不想用开关，就是一上电就启动的话，就把开关按键去掉，key-table那个结构体里开关索引去掉，主函数了相应去掉相关行程序。
