Description: This is a photo of a general purpose timer/counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card. It gives high-resolution timing (microseconds). Because of its programmablity, it is very powerful and flexible. You can even control DC or servo motors using pulse-width modulated (PWM), or stepper motors using its square wave capabilities. The figure below is the actual output (square wave) from the 8254 card captured by an oscilloscope:

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: 可编程间隔定时器（Programmable Interval Timer，PIT， 8253或8254模型），也叫做系统时钟，是一个非常有用的芯片，可以在一定时间间隔精确地产生中断。芯片本身有3个通道：通道0绑定到IRQ0，在可预知和规则的时间中断CPU；通道1特定于系统；通道2则连接到系统扬声器。就像你看到的一样，单个的芯片为系统提供了几个非常重要的服务。-Programmable Interval Timer (Programmable Interval Timer, PIT, 8253 or 8254 model), also known as the system clock, is a very useful chip in a certain time interval can be accurately generate an interrupt. Chip itself has three channels: channel 0 bound to IRQ0, and rules in the foreseeable time interrupt CPU channel 1-specific systems 2-channel speaker connected to the system. As you see, like a single chip for the system provides several important services.
