摘要
针对传统的数字时钟采用较多的分立元件,存在着精度低、误差大等缺陷,采用单片机HT68F40为控制核心,利用时钟芯片DS1302计时,研制了一台电子时钟,介绍了系统的硬件和软件开发流程.该电子时钟工作稳定,提高了时间精确度,具有较为广泛的应用前景.
The traditional digital clocks used lots of discrete components with the drawbacks of low timing precision and big errors .Therefore , this paper developed an electronic clock and introduced its develop-mental process in terms of hardware and software .The core of electronic clock was HT68F40 single-chip microcomputer with which to get timing message from DS 1302.The clock worked stably with improved precision .It also had a wide application prospect .
