摘　　要：设计了一个实时日历时钟显示系统,该系统以AT89C51单片机作主控芯片,并分别以DS12C887作时钟日历芯片,以LCD1604作为显示器件。通过单片机的控制,读取时钟芯片的年、月、日、时、分、秒及星期并将其显示在LCD1604液晶显示屏上。此外,还可通过校时电路对时间进行修改。在该设计中,使用C语言编写系统软件,采用Proteus软件进行硬件电路仿真。通过Keil C与Proteus的联合调试,结果表明,该系统有显示稳定,精度高,操作简易等优点。A real-time calendar clock display system was designed.This system was controlled by AT89C51 single chip microcomputer.DS12C887 was a calendar clock chip, and LCD1604 was a display device. This system can read the year, month, day,hour, minute, second, week from DS12C887 and show them on LCD1604. In addition, the time of this system can be modified by the timing circuit. The software was written by C language, and the hardware circuit was simulated by Proteus software. By the joint deugging of Keil C and Proteus, the result shows that the system has the advantages of stable display, high accuracy and easy to operation.
