单片机万年历程序怎样读取时间

㈠ 我想做一个单片机控制的家用万年历，显示时间，温度。希望高手指点指点，（我要买什么部件，和程序怎么写）

为了学习的话，可以用单片机内部定时器做时间显示，也可以用楼上说的专用芯片；温度传感器用18B20，简单，同时可以学习单总线，也可以用热敏电阻，可以学习ADC转换控制。建议先用proteus仿真，仿真成功了，可散槐以用洞洞板自己焊，毕竟出电路板的话还要学PCB软件，做PCB的话自己用光刻板做也比较麻烦，发厂家做成本较高；买个STC89C52（串口下载，方便），做个最小系统，测试没问题了，加入显示电路（数码管 or LCD1602都行），搞定。
可以看一冲桐友下郭天祥的书和视频教轮闭程~

㈡ 单片机万年历的c语言程序

呵呵，这个东西我最近做过。也用过DS1302、PCF8563时钟芯片，还算比较简单啦。
只不过没这么多功能，这些日子正想做个跟手表一样多的功能。等做完了，发给你把。你加我的网络Hi吧。
我可以帮助你，你先设置我最佳答案后，我网络Hii教你。

㈢ 求大神解答下单片机80c51，下面程序中的一个能够让万年历调时间的代码，求大神告诉下这些代码

DS_WriteBCDBata(0x80,second|0x80);

这个函数应该是把秒写到DS1302芯片的秒寄存器中，秒的寄存器的地址上80和81两个地址（寄存器0）。寄存器0中最高位 CH 是一个时钟停止标志位。如果时钟电路有备用电源，上电后，我们要先检测一下这一位，如果这一位是 0，那说明时钟芯片在系统掉电后，由于备用电源的供给，时钟是持续正常运行的；如果这一位是 1，那么说明时钟芯片在系统掉电后，时钟部分不工作了。如果 Vcc1 悬空或者是电池没电了，当我们下次重新上电扒镇袜孙时，读取这一位，那这一位就是 1，我们可以通过这一位判断时钟在单片机系统掉电后是否还正常运行。剩下的7 位高 3 位是秒的十位，低 4 位是秒的个位，这里再提请注意一次春好粗，DS1302 内部是 BCD 码，而秒的十位最大是 5，所以 3 个二进制位就够了。second|0x80后面的这个数据使用 | 符号就是把最高位CH变成1.

㈣ C51单片机的万年历程序设计

我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

㈧ 单片机万年历

今天碰到了N个白痴问题。万年历是能够显示年月日、二十四节气、农历之类的东西，单片机是一块芯片。万年历可以用单片机来做，但是我真不知道“万年历单片机”怎么做。我想你应该想问的是怎么用单片机来做万年历，我提供思路。 1、单片机最小系统一块。可以用STC89C52芯片+外围电路。可以烧入用户编写的程序，实现万年历所需的逻辑。 2、实时时钟电路一块，可以用DS1302芯片。提供年月日、时分秒数据给单片机。 3、显示器电路一块。用来显示这些数据。 4、一些必要的按键，用来调整数据。
