Description: 十字路口交通灯管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实现。

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.

[assembly language] 表盘式时钟汇编原代码

Description: 基本设计要求 1 在屏幕上显示一个适当大小的圆形，再圆形道上均匀的分配着60个点，代表1秒—60秒的位置，凡是5倍的点应当比其他的大。 2 以圆中心为轴，画一条斜线代表秒针，采用定时中断方式，每过1秒钟，秒针移动一个位置。 3 定时源可以使用试验箱上的8253。 4 按“ESC”之后，结束演示。 - The basic design requests 1 on the screen to demonstrate a suitable size the circular, the circular on even assignment 60 spots, are representing 1 second 鈻?0 second positions again, every is 5 time of spots must compared to other big. 2 take the round center as an axis, draws an oblique line to represent the second hand, uses fixed time severs the way, each 1 second, the second hand has moved a position. 3 fixed time sources may in the field test box 8,253. After 4 presses \"ESC\", the conclusion demonstrates.
