AVR单片机入门及C语言高效设计实践（五）
ATMEAG16L的中断系统什么是“中断”？顾名思义中断就是中断某一工作过程去处理一些与本工作过程无关或间接相关或临时发生的事件，处理完后，则继续原工作过程。比如：你在看书，电话响了，你在书上做个记号后去接电话，接完后在原记号处继续往下看书。如有多个中断发生，依优先法则，中断还具有嵌套特性。又比如：看书时，电话响了，你在书上做个记号后去接电话，你拿起电话和对方通话，这时门铃响了，你让打电话的对方稍等一下，你去开门，并在门旁与来访者交谈，谈话结束，关好门，回到电话机旁，拿起电话，继续通话，通话完毕，挂上电话，从作记号的地方继续往下看书。由于一个人不可能同时完成多项任务，因此只好采用中断方法，一件一件地做。[第一段]
-AVR C language portal and efficient design practice (5) ATMEAG16L the system even interrupted Mody is "suspended"? As the name suggests is interrupted interruption of a process to deal with some of the work process unrelated or indirectly related to the temporary or , after treatment, to the original process. For example : in your reading, the phone rang, you have the book to be a mark after picking up the telephone, then after the original mark to continue down the reading. For more interruption, priority rules and the suspension characteristics also have nested. For instance : reading, the phone rang, you have the book to be a mark after pick

本系统采用MSC
本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。本系统实用性强、操作简单、扩展功能强。 -The system uses MSC-51 series single-chip ATSC51 and programmable parallel I/O interface chip 8255A-centric device designed to control traffic lights, can be achieved in accordance with the actual traffic flow through the P1 port 8051 chip set red, green fuel Liang function of time traffic light cycle, the countdown five seconds left when the yellow light flashing warning (traffic lights through the PA output signal indicates the time directly through the PC port output 8255 to double-digits) vehicle alarm闯红灯 green time traffic flow can be detected through a double-digital display. The system practical, simple and strong extensions.
