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。

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。
