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.

Description: 1.VR1 为 3X3 体积硬封 10K 可调电位器，可以进行对比度调节。当电位器缺口
大致对准 R1 电阻时，此时液晶屏对比度为正常范围内，显示较清晰，可以液晶
接口第三脚 V0 不用接。
当电位器缺口对准 VR1 丝印时，此时相当于电位器是零电阻值，可以用螺丝刀
手动调节液晶电位器至 R1 位置直到显示屏正常清晰显示
液晶屏自己带电位器时，第三脚 V0 可接可不接，不接必须调节液晶背面电位器
至 R1 位置。接了 V0 可以通过外接电位器调节，同时也可以用液晶电位器调。
2．液晶接口 18 脚 VOUT 可以不接 悬空
3.串并行显示可通过下列两种方式调节：
一种 PSB 脚控制 程序内部高低电平选择 H-并行；L-串行
二种 JP2 短路点有 3 点，S 和中间点连起来为串行 P 点和中间点连起来为并行
如取字模出现乱码时，请一定把 JP2 短接 P 为并口 S 为串口

When roughly aligned R1 resistance, and the LCD display contrast within the normal range, showing more clearly, can the LCD
The third leg V0 interface not connected.
When VR1 potentiometer alignment notch silk, then the equivalent potentiometer resistance value is zero, you can use a screwdriver
Potentiometer to manually adjust the LCD display normal R1 position until a clear display
When the LCD screen yourself potentiometer, the third leg V0 can be accessed from time to connect, then do not have to adjust the LCD back potentiometer
To R1 position. V0 can pick up an external potentiometer adjustment, but you can also use the LCD potentiometer adjustment.
2. LCD Interface 18-pin VOUT can not take vacant
3 serial parallel display can be adjusted by the following two ways:
One kind of PSB feet high and low level of internal control procedures to select H
