这是我自己做的１６０２液晶，包括ＰＲＯＴＵＥＳ原理图，希望对大家有用。...

这个是个4个数码管显示时间的程序，用AT89S52实现，用四个按键控制，能实现时钟显示，闹钟定时，倒计时三项功能，电路图很简单。-This is a 4 digital tube display time-consuming procedures, use AT89S52 realize, with four buttons control, can realize the clock display, alarm clock, timer, countdown to the three functions, circuit is very simple.

 本文附带一份小项目的源代码，它超越了串口助手，给人一种耳目一新的感觉。亮点如下： 1. 它解决了串口关闭时出现线程出现死锁，软件关闭后，进程在后台没有关闭问题（所谓的线程死锁），可以直接用到开发的项目上。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
