基于PCF8563时钟芯片的万年历制作

万年历是一种能够显示日期、星期和时间的工具，它不仅能够告诉我们当天是几号，还能显示星期几和当前时间。

在这个项目中，我们将使用PCF8563时钟芯片来制作一个基于PCF8563的万年历。

PCF8563是一种CMOS实时时钟和日历芯片，它可以提供年、月、日、星期和小时、分钟、秒的数据。

它具有电源管理功能，可以通过一个电源低于2V脉冲输入来切换系统电源供电方式。

为了制作这个基于PCF8563的万年历，我们需要以下材料和工具：1. Arduino主控板2.PCF8563时钟芯片3.16x2液晶显示屏4.面包板5.杜邦线6.10k电阻接下来，我们将按照以下步骤来制作基于PCF8563的万年历：第一步：连接电路首先，将Arduino主控板插入面包板。

接着，连接PCF8563时钟芯片到Arduino主控板上的I2C总线。

将SDA引脚连接到A4引脚，将SCL引脚连接到A5引脚。

此外，还需要使用10k电阻将VCC引脚连接到VCC引脚上。

接下来，将16x2液晶显示屏连接到面包板。

连接液晶屏的RS引脚到Arduino主控板的D12引脚，RW引脚到GND引脚，和E引脚到D11引脚。

将液晶屏的D4到D7引脚连接到Arduino主控板的D5到D2引脚。

第二步：编写代码打开Arduino IDE并创建一个新的项目。

然后，编写以下代码：#include <Wire.h>#include <LiquidCrystal_I2C.h>//定义PCF8563的地址#define PCF8563_ADDR 0x51//定义显示屏的尺寸#define LCD_COLUMNS 16#define LCD_ROWS 2LiquidCrystal_I2C lcd(0x27, LCD_COLUMNS, LCD_ROWS);void setup//初始化I2C总线Wire.begin(;//设置时钟芯片为24小时模式Wire.beginTransmission(PCF8563_ADDR);Wire.write(0x02);Wire.write(0x00);Wire.endTransmission(;//初始化液晶显示屏lcd.begin(LCD_COLUMNS, LCD_ROWS);lcd.setCursor(0, 0);lcd.print("Date: ");lcd.setCursor(0, 1);lcd.print("Time: ");void loop//读取PCF8563的日期和时间Wire.beginTransmission(PCF8563_ADDR); Wire.write(0x02);Wire.endTransmission(;Wire.requestFrom(PCF8563_ADDR, 7);int second = bcdToDec(Wire.read( & 0x7F); int minute = bcdToDec(Wire.read();int hour = bcdToDec(Wire.read( & 0x3F); int dayOfWeek = bcdToDec(Wire.read();int dayOfMonth = bcdToDec(Wire.read();int month = bcdToDec(Wire.read( & 0x1F); int year = bcdToDec(Wire.read();//显示日期和时间lcd.setCursor(6, 0); printWithLeadingZero(dayOfMonth);lcd.print("/");printWithLeadingZero(month);lcd.print("/");lcd.print(2000 + year);lcd.setCursor(6, 1); printWithLeadingZero(hour);lcd.print(":");printWithLeadingZero(minute);lcd.print(":");printWithLeadingZero(second);delay(1000);//将BCD码转换为十进制int bcdToDec(int bcd)return (bcd / 16 * 10) + (bcd % 16);//打印带有前导零的数字void printWithLeadingZero(int number)if (number < 10)lcd.print('0');}lcd.print(number);第三步：上传代码将Arduino主控板连接到电脑，并根据需要选择正确的端口和板类型。

PIC单片机学习笔记之万年历

PIC单片机自学笔记之万年历实验环境：Proteus编程语言：汇编编程环境：MPLAB IDE单片机：PIC16F877晶振：20MHz实验目的用的定时器定时扫描的方式消除键盘抖动的影响，提高了程序的运行速率；可对分钟、小时、日期、月份和年份进行调节。

实验效果图如图1和图2.图1—系统开机效果图图2—调整时间后的显示状态PCF8563芯片概述：PCF8563 有16 个位寄存器：一个可自动增量的地址寄存器，一个内置32.768KHz的振荡器（带有一个内部集成的电容）一个分频器（用于给实时时钟RTC 提供源时钟）一个可编程时钟输出，一个定时器，一个报警器，一个掉电检测器和一个400KHz I2C 总线接口。

所有16 个寄存器设计成可寻址的8 位并行寄存器，但不是所有位都有用。

前两个寄存器（内存地址 00H，01H）用于控制寄存器和状态寄存器，内存地址 02H~08H 用于时钟计数器（秒~年计数器），地址09H~0CH 用于报警寄存器（定义报警条件），地址 0DH 控制CLKOUT 管脚的输出频率，地址0EH 和 0FH 分别用于定时器控制寄存器和定时器寄存器。

秒、分钟、小时、日、月、年、分钟报警、小时报警、日报警寄存器，编码格式为BCD，星期和星期报警寄存器不以 BCD 格式编码。

当一个RTC 寄存器被读时，所有计数器的内容被锁存，因此，在传送条件下，可以禁止对时钟日历芯片的错读。

MAX7219概述：MAX7219/MAX7221是一种集成化的串行输入/输出共阴极显示驱动器,它连接微处理器与8位数字的7段数字LED显示，也可以连接条线图显示器或者64个独立的LED。

其上包括一个片上的B型BCD编码器、多路扫描回路，段字驱动器，而且还有一个8*8的静态RAM用来存储每一个数据。

只有一个外部寄存器用来设置各个LED的段电流。

MAX7221与SPI™QSPI™以及MICROWIRE™相兼容，同时它有限制回转电流的段驱动来减少EMI（电磁干扰）。

单片机万年历

关键词：时钟芯片DS12C887；温度采集DS18B20；单片机AT89S52;液晶显示1602摘要电子万年历是一种非常广泛日常计时工具，对现代社会越来越流行。

它可以对年、月、日、周日、时、分、秒进行计时，还具有闰年补偿等多种功能。

本系统选用DALLAS公司生产的日历时钟芯片DS12C887来作为实时时钟芯片，为本系统提供详细的年、月、日、星期和小时、分钟等时间信息。

数字万年历采用直观数字显示，可以同时显示年、月、日、周日、时、分、秒和温度等信息，还具有定时和时间校准等功能。

该电路采用AT89S52单片机作为核心，功耗小，能在3V的低压工作，电压可选用3~5V电压供电。

本系统硬件部分由AT89S52单片机、DS12C887时钟芯片、1062液晶显示器、DS18B20温度测量、键盘、蜂鸣器系统等部分构成。

软件部分在keil 环境下用C51语言编写，包括时间设置、时间显示、定时设置、定时闹钟、温度显示。

没有良好的基础知识和实践经验会受到很大限制，每项功能实现时需要那种硬件，程序该如何编写，算法如何实现等，没有一定的基础就不可能很好的实现。

在编写程序过程中发现以现有的相关知识要独自完成编写任务困难重重，在老师和同学的帮助下才完成了程序部分的编写。

文章后附有电路原理图、程序清单，以供读者参考。

因水平有限，难免有疏落不足之处，敬请老师和同学能给与批评指正。
