C语言Lcd1602万年历闹钟Proteus仿真单片机毕业课程电子设计
C语言Lcd1602万年历闹钟Proteus仿真单片机设计
AT89C51+Lcd1602+DS1302+独立按键+蜂鸣器
Lcd1602万年历闹钟。
时间信息来自DS1302，显示采用
Lcd1602，蜂鸣器提供闹音和按键提示音。
液晶上面显示年月日时分秒星期以及闹钟时间。
有时间调节和闹钟调节，可以调节年月日时分秒星期信息以及闹钟时间。
具体介绍如下。
1.做好的仿真图，如下图所示。
2.启动仿真后，先在液晶屏显示系统信息，然后在第二屏显示需要的万年历闹钟信息。
如下图所示！
3.通过单片机右侧的三个按键，即可设置闹钟。
如下图所示。
4.通过单片机左侧的四个按键，来设置年月日时分秒星期的值。
设置时，参数闪烁，同时会有按键提示音。
5.本设计默认套餐1，具体套餐详情请看下面的发货清单。
如需要其它套餐，请联系客服询问。

（2）、由图1所示：正常显示（上电显示）如下：星期时分两红灯亮秒闪（3）、●按下key1第一次，显示如下：年月{阳历}日{阳历}两红灯亮两灯亮●再按下key1，则回到正常显示，依次类推。
（4）、在任何显示状态下，按下key1超过2秒，则进入设置状态，同时显示“时、分、秒”闪烁。
此时按下key2，“秒”闪，进入设置状态。
再按下key2，“分”闪，进入设置状态。
再按下key2，“时”闪，进入设置状态。
再按下key2，显示“星期、月{阳历}、日{阳历}”，同时“日{阳历}”闪，进入设置状态。
再按下key2，“月{阳历}”闪，进入设置状态。
再按下key2，“星期”闪，进入设置状态。
再按下key2，显示“年(四个数码管显示)”，同时“年”闪，进入设置状态。
再按下key2，则回到“秒”重复设计置。
注：进入设置状态时，key3作减键，key4作加键，并且key3，key4具有连动功能（如果key3或者key4按下持续1秒后，以0.5秒时间连减或者连加）（5）、在（2）的任何状态下，按下key5，则回正常显示。
（6）、在正常显示状态下：按下key5超过2秒，则进入闹钟设置状态。
Fax：86-0731-******* Mail：dsc52@ Web： 再按key5则回正常显示。
三、扩展功能要求。
（1）、按下key6，把闹钟时间存于AT24C16里。
（2）、由图1所示：正常显示（上电显示）如下：星期时分两红灯亮秒闪（3）、●按下key1第一次，显示如下：年月{阳历}日{阳历}两红灯亮两灯亮●按下key1第二次，显示如下：年月{阴历}日{阴历}两红灯闪两灯闪●再按下key1，则回到正常显示，依次类推。
（4）、在任何显示状态下，按下key1超过2秒，则进入设置状态，同时显示“时、分、秒”闪烁。

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。
