摘要
介绍了采用单片机来开发时钟芯片，使整个系统能够同时显示年、月、日、星期、时、分、秒，具有自动校时的功能，每天校正两次，使误差控制在一定范围内，实现准无误差，避免了累计所造成的更大误差。
In this paper, the development of single chip computer clock is introduced. The whole system can display year, month, week, hour, minute and second at the same time, and also it can make correction of time automatically. Every day correction is made twice, thereby the error can be controlled within a certain limit, the quasi non error realized and larger error caused by accumulating avoided.
