Description: hhh理现对交通信号灯进行管理，车辆放行3分钟后，车行道黄灯闪烁5秒钟，以警示车辆将切换红绿灯。此时人行横道仍维持红灯点亮。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-HHH Jimmy is right for traffic signal management, vehicle clearance three minutes later, the driveway five seconds flashing yellow light to warn vehicles will switch traffic lights. This sees the red light remains lit. The flashing yellow light carriageway 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 Platform: |

Description: 1、 南北和东西方向各有一组绿、黄、红灯，绿灯黄灯和红灯的持续时间分别为20秒、5秒和25秒，控制器控制交通灯的颜色按照交通规则进行变化..
2、 2、用两组数码管，以倒计时方式显示两个方向允许或禁止通行的时间；
3、当有特殊情况（如消防车等）时，两个方向均为红灯，倒计时停止，当特殊情况结束后，控制器应返回原状态，继续正常运行；
-a north-south and east-west direction at a group of green, yellow, red, green yellow and red respectively, the duration of 20 seconds, five seconds and 25 seconds, the controller to control the color of traffic lights in accordance with the traffic regulations for changes .. 2, 2, with two sets of digital controls to savers when shown two directions to allow or prohibit the passage of time; three, when there are special circumstances (such as fire engines and so on), in both directions were red lights, to stop the countdown, when special circumstances after the controller should return to the original state, to continue normal operations; Platform: |
