Description: 十字路口交通信号灯控制系统的设计基本要求：（利用8088、8254、8255及其它器件实现交通信号灯控制）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向： 红（30秒），黄（5秒），绿（25秒） 东西向： 红（35秒），黄（5秒），绿（25秒） 上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。--A traffic light system. It uses 8088, 8254, 8255 and other modules to control the lights.

Description: 电子选择器，是利用TND－MD教学系统实现的，用来作为特定场合投票机器统计使用。所用到的芯片主要有8253定时计数器、8255A并行接口电路芯片等。使用时，用户用键盘输入A，B，C，D这四个字母中的一个来作为已经选择的项目，程序将在屏幕上对应显示已经选择的“A,B,C或者D”，并且通过控制扬声器，发出对应的频率声音信号，同时相对应的LED灯也对应发光，以便于位于远处的计票员进行远程计票。-Electronics selector is the use of TND-MD teaching system implementation, and used as a specific occasion the use of voting machines and Statistics. Used by the main chip has 8253 regular counters, 8255A parallel interface circuit chips. When used, the user with keyboard input A, B, C, D in these four letters as a selection of projects has been, the program will display on the screen has been chosen corresponding to " A, B, C or D" , and through control speakers, the issue of the corresponding frequency of the voice signal, while the corresponding LED lights also light-emitting counterparts, so far located in remote tellers tellers.
