摘要
电子万年历是一种日常广泛应用的计时工具,在现代社会中越来越流行。数字电子万年历采用直观的数字显示,可以同时显示年、月、日、周、时、分、秒、温度等信息,还具有时间校准等功能。第三次革命就是单片机数码计时技术的应用(电子万年历),使计时产品的走时日差从分级缩小到1/600万秒,从原有传统指针计时的方式发展为人们日常更为熟悉的夜光数字显示方式,直观明了,并增加了全自动日期、星期、温度以及其他日常附属信息的显示功能,它更符合消费者的生活需求!因此,电子万年历的出现带来了钟表计时业界跨跃性的进步。
本文中万年历的设计过程在硬件与软件方面进行同步设计,硬件部分主要由AT89C51单片机,液晶显示电路,复位电路,时钟电路,稳压电路电路等组成。在单片机的选择上使用了AT89C51单片机,该单片机适合于许多较为复杂控制应用场合,显示器使用液晶LCD1602。软件方面主要包括日历程序、液晶驱动程序、显示程序等,这些程序采用C语言编写。所有程序编写完成后,在Keil C51软件中进行调试,确定没有问题后,在Proteus软件中嵌入单片机内进行仿真。并且利用Protel软件进行制图,画出PCB图并且制作出实物。

ABSTRACT
E-calendar is a very extensive daily timing tool, more popular in modern society. For digital electronic calendar using intuitive digital display, simultaneously displays year, month, day, day, hour, minute, second, temperatures and other information, also with a time calibration capabilities. The third revolution is a single-chip digital timing technology ( electronic calendar ), so that the timing product walk time difference from graded narrowing to 1/ 6000000 of a second, from the original traditional pointer timing for the development of people's daily more familiar luminous digital display, intuitive and clear, and the increase of the full automatic date, week, temperature and other daily auxiliary information display function, which is more in line with consumer needs. Therefore, the electronic calendar brings a watch industry a big progress.
Synchronizing design of calendar is based on hardware and software design. Hardware part by AT89C51 microcontroller, circuit for LCD, reset circuit, clock circuits, voltage-stabilizing circuit and serial download circuits and ponents of the circuit. On the choice of using single-chip puter AT89C51 microcontroller, the microcontroller is suitable for a host plex control applications. Monitor LCD LCD1602. Software includes calendar, LCD drivers, display program. Programs using a languag
