单片机课程设计之万年历、闹钟与温度显示设计

单片机课程设计之万年历、闹钟与温度显示设计
根据方案的选择，数码管时钟温度系统由51单片机、时钟芯片DS1302、测温芯片DS1802、数码管显示电路、键盘电路组成，如图3-1所示。
本系统采用C语言编写，控制器采用单片机STC89C52，温度检测部分采用DS18B20温度传感器，时钟系统用时钟芯片DS1302，用八位数码管作为显示器。单片机通过时钟芯片DS1302获取时间数据；通过温度传感器DS18B20采集温度信号送给单片机处理，并在数码管中显示出来，键盘可以切换界面，调时和温度查询与设置闹钟的功能。
由于DS18B20是在一根I/O线上读写数据，因此，对读写的数据位有着严格的时序要求。DS18B20有严格的通信协议来保证各位数据传输的正确性和完整性。该协议定义了几种信号的时序：初始化时序、读时序、写时序。所有时序都是将主机作为主设备，单总线器件作为从设备。而每一次命令和数据的传输都是从主机主动启动写时序开始，如果要求单总线器件回送数据，在进行写命令后，主机需启动读时序完成数据接收。数据和命令的传输都是低位在先。电路图如图3－4所示。
6、数码管显示电路设计
数码管内部是由7个条形发光二极管与一个小圆点发光二极管组成，根据这八个二极管的亮暗组成不同的字符。本系统采用八位数码管作为显示模块，数码管相对其他LCD类的显示器来说，成本比较低廉，省电。两个四位共阴0.56英寸的数码管作为显示屏。如图3-6所示。
7、按键控制电路设计
本系统采用四个按键作为键盘控制实现界面切换的功能，如图3-7所示。能够实现界面切换、时间校正、闹钟设置等功能。机械式按键再按下或释放时，由于机械弹性作用的影响，通常伴随有一定时间的触点机械抖动，然后其触点才稳定下来。其抖动过程如图3-8所示。抖动时间的长短与开关的机械特性有关，一般为5-10 ms。故软件编程时需要注意消除抖动。

单片机万年历程序(带闹钟)

单片机万年历程序(带闹钟)

第一章设计方案1.1.硬件设计1.1.1设计要求实现年月日、时分秒、星期的显示功能，用两个按键来实现日期和时间的调整功能，调整要求星期能自动更新，且能实现位调。

显示格式：四位年，两位月，两位日，星期字母前三位，两位时，两位分，两位秒。

比如：YYYY-MM-DD WEEKHH:MM:SS1.1.2硬件框图图1-1-硬件框图日期时间由硬件软件结合产生;按键之间相互配合完成当前日期时间的调整功能。

过程与结果由控制芯片分别输出到显示器上。

本设计附加了播放音乐的功能。

音乐从蜂鸣器产生。

1.1.3硬件选择1）.显示模块本设计具体选用与实际应用与消耗资源相关。

万年历用到的地方大多都在室内。

现市场上与许多显示器，在日常生活中最常见的有数码管，led点阵屏，lcd液晶显示器等。

八段数码管的优点：亮度高，显示大。

驱动部份的软件简单；缺点：与液晶相比，耗电及体积大。

数码管只能单纯的显示数字，不能生动的表达各个参数的信息，消耗电力也比led液晶显示器大。

LCD液晶显示器它是一种专门用来显示字母、数字、符号等的点阵型液晶模块，在单片机系统中应用晶液显示器作为输出器件有以下几个优点：显示质量高，由于液晶显示器每一个点在收到信号后就一直保持那种色彩和亮度，恒定发光，而不像阴极射线管显示器（CRT）那样需要不断刷新新亮点。

因此，液晶显示器画质高且不会闪烁。

数字式接口，液晶显示器都是数字式的，和单片机系统的接口更加简单可靠，操作更加方便。

体积小、重量轻，液晶显示器通过显示屏上的电极控制液晶分子状态来达到显示的目的，在重量上比相同显示面积的传统显示器要轻得多。

功耗低，相对而言，液晶显示器的功耗主要消耗在其内部的电极和驱动IC上，因而耗电量比其它显示器要少得多。

Lcd液晶能一屏把本设计所要显示的信息表达完整。

而且lcd耗电小，体积小很适合与室内使用。

本设计的要求日期时间以数字表示、星期用3位英文字符表示共21个字符，lcd1602能显示32个字表 1-1 lcd1602引脚及功能2）.按键与蜂鸣器本设计选用轻触按钮，型号为XDJT1102S。

c51单片机万年历的c程序c51单片机万年历的c程序求一个单片机可以显示阳历的年、月、日、星期、小时.分.秒。

阴历也能显示，标明是否为闰年。

用LCD液晶显示，可以调整时间。

这有个数码管显示的程序以前做的，。

你可以在我这个程序上修改修改包括键盘扫描，还有动态显示。

单片机万年历汇编闹钟时间可调程序(LCD1602,DS18B20,DS1302,MAX810L)

片机万年历汇编闹钟时间可调程序(LCD1602,DS18B20,DS1302,MAX810L)说明：0该程序全部是用汇编语言编写1．该程序附带有温度显示，并且带有闹铃功能2．正常时间和闹钟时间都可以用键盘设置3．该程序是使用LCD1602显示年月日，格式为TIME XX-XX-XX XX，由于屏幕的关系,所以就不显示周的数据，其中闹铃调整的上界面是“BELLADJUST”4．该程序的时间是由时钟芯片DS1302提供的，据说很精准，目前看起来确实是这样的，刚开始我是使用定时器计时的，但是不怎么精准，可能是我的汇编技术有限才导致，所以本人就把这个版本呈上，希望诸位多多斧正5．该程序的温度是通过DS18B20提取的，这个模块是我从别人那里COPY过来的，O(∩_∩)O~，显示是肯定没问题的6．该程序也有用MAX810l的复位功能，但是好像这一点还没被体现出来7．烧程序我使用的是MAX232外加几个极性电容，还有一个RS232,不幸的是我的PCB板的RS232的封装画错啦！！~~~~(>_<)~~~~8．该万年历是由五个按键控制的，SW5复位，SW1调时间，调年月日时分秒，除秒可以加减调节之外其余的调节都是只能加不能减（自我觉得如果增加减的功能会觉得程序复杂，所以免！）， SW4 是用来调节闹钟的时分秒的，和SW1按键不同的是时分秒都能加减，当闹钟设置的时间和正常显示时间的时分秒相同时，闹铃十秒钟，期间你可以按SW4键终止响铃，SW2 和SW3 分别是用来加减时间的！9．说了这么多，最后说说自我认为的缺陷，行家应该都一眼就看出一些破绽了，那就是按键消抖的问题，这个我觉得有点麻烦所以本人就把这个问题留给阅览资料的你吧！10．废话说了这么多，最后把我的程序，ORCAD电路原理图，PADS软件的PCB图，以及一张实物图献上，希望你能喜欢，页脚有我的Email（prettyboy2009@），欢迎随时交流！程序：;*************************************************************** ;***************************************************************RS BIT P2.5RW BIT P2.6E BIT P2.7SU BIT P1.6 ;1302串行口数据端RST BIT P1.5CLK BIT P1.7ALARM BIT P2.3JIAN BIT P2.2 ;减JIA BIT P2.1 ;加MOSHI BIT P2.0 ;模式DQ BIT P1.0SOUND BIT P1.3NIAN EQU 7FHYUE EQU 7DHDAY EQU 7CHHHH EQU 7EHSHI EQU 7BHFEN EQU 7AHMIAO EQU 79HASHI EQU 78HAFEN EQU 77HAMIAO EQU 76HGEW EQU 75HA_BIT EQU 70H ;18B20B_BIT EQU 6FHFLAG EQU 6EHDS1302_ADDR EQU 6DHDS1302_DATA EQU 6CHORG 0000HLJMP STARTORG 0030H ;***************************************************************;

这个程序是在1602液晶上显示世界时钟，并且能设定闹钟，链接闹钟的引脚为p1^4，w1控制位选，w2控制加一，w4控制减一
w6为闹钟模式和时钟模式的切换键，按一下w6可设定那种时间，w2单独使用时为开关闹钟，中间屏蔽了一段18b20温度显示程序，把屏蔽去除后也能在液晶上显示温度
