Description: 十字路口交通灯管理现对交通信号灯进行管理，车行道的黄灯闪烁5秒钟后，转为人行横道行人放行1分钟，然后再转为车行道车辆放行3分钟。如此循环重复。 用发光二极管模拟信号灯，8255A实现对信号灯的控制（所用端口自定），8253的计数器2定时向实验系统主片8259A的IRQ7请求中断，以实现3分钟，5秒钟和1分钟的定时。 实验系统8253计数器2的CLK2可接OPCLK，频率为1.19318MHZ，GATE2已接＋5V，定时可采用软硬件结合相结合的方式实现。-traffic lights at a crossroads right now management for traffic signal management, the driveway flashing yellow light five seconds later, the pedestrian crossings to release a minute and then released into driveway vehicles for three minutes. So the cycle to repeat. Using light-emitting diode signal simulation, 8255A right signals control (used to set the port), the 8253 regular counter to the two experimental system of the main unit there 8259A interrupt request, to achieve 3 minutes, 5 seconds and one minute timing. Experimental System to the 8253 counter two OPCLK CLK2 access, frequency of 1.19318MHZ, GATE2 has received+5 V, which combines hardware and software regularly use a combination of ways.

Description: 交通信号灯的控制：
1． 通过8255A并口来控制LED发光二极管的亮灭。
2． A口控制红灯，B口控制黄灯，C口控制绿灯。
3． 输出为0则亮，输出为1则灭。
4． 用8253定时来控制变换时间 。
要求：设有一个十字路口，1、3为南，北方向，2、4为东西方向，初始态为4个路口的红灯全亮。之后，1、3路口的绿灯亮，2、4路口的红灯亮，1、3路口方向通车。延迟30秒后，1、3路口的绿灯熄灭，而1，3路口的黄灯开始闪烁（1HZ）。闪烁5次后，1、3路口的红灯亮，同时2、4路口的绿灯亮，2、4路口方向开始通车。延迟30秒时间后，2、4路口的绿灯熄灭，而黄灯开始闪烁。闪烁5次后，再切换到1、3路口方向。之后，重复上述过程。
-traffic signal control : 1. A parallel port by 8255 to control the LED light emitting diodes-destruction. 2. A red light population control, population control yellow B and C population control green. 3. Output-0, the output of a destruction. 4. Use 8253 to control transform regular time. Requirements : there is a crossroads, 1,3 to the south, to the north, the east-west direction 2,4. Initial state for four junctions in the whole bright red light. After 1,3 junctions green light, red light junctions in the 2,4-, 1,3 junctions opening direction. Delayed 30 seconds after the green light junctions 1,3 out and the junction of 1,3 begin blinking yellow light (1HZ). Stars 5, 1,3 junctions in the red light, green light junctions in the 2,4-, 2,4 direction was opened to traffic junctions. Delayed
