交通灯控制器的设计与实现主要是通过编写汇编语言程序利用8255A与8253对灯的亮与灭及时间进行控制。首先，要了解的是8255A与8253是如何工作的，包括它的A口、B口、C口和控制端口是如何写数据的以及如何使用8253定时来控制变换时间。-Traffic light controller design and implementation is mainly by writing assembly language programs using 8255A and 8253 pairs of bright light and time control and eradication. First of all, to understand that the 8255A and 8253 is how to work, including its A port, B port, C port and control port is how to write the data and how to use 8253 timer to control the conversion time.
