该时钟电路主要以单片机AT89S52为核心而设计的，通过单片机对信息的分析与处理控制外围设备。电路整体设计思想是想把它做成一个实用的器件，所以在题目要求的前提下，我们又加入了星期程序，温度程序，年、月、日程序以及时间的12—24转换程序。-The clock circuit is mainly designed to AT89S52 microcontroller as the core, through the microcontroller for information analysis and process control peripherals. Circuit whole idea is trying to make it into a practical device, so the premise of questions asked, we joined the week program, temperature program, year, month, day and time of the 12-24 program conversion program.
