网上找到的PCF8563程序基本不能用 本程序基于51单片机，模拟了I2C接口，现已调试成功，可以做成万年历了...

实时时钟芯片DS1302采用串行接口，只需3根引脚便可以完成操作，其使用非常方便。这里采用AT89S52单片机作为外部微处理器，来对DS1302进行控制-Real-time clock chip DS1302 serial interface, only three pins will be able to complete the operation, its use very convenient. AT89S52 microcontroller used here as an external microprocessor to control of the DS1302
