求翻译：十字路爱i情通灯实现了交叉路口的车辆控制，本次课程设计主要实现了并行接口8255传送信息并用发光二极管来倒计时，8253和8259的组合搭配，实现了倒计时中断，最终在LED管上每秒变化一次，以模拟实现红绿灯的功能是什么意思？

Intersection traffic lights to achieve the intersection of vehicle control, this program primarily designed to achieve a parallel interface 8255, and transmit information using light-emitting diode to the countdown, with a combination of 8253 and 8259 to achieve a countdown interrupt per second on t

crossroads has achieved 10 traffic lights at intersection of vehicle control, and the design of the curriculum leading to a parallel interface 8255 transmission of information and used light emitting diodes are 2 countdown to 8253 and 8259, the portfolio mix, and achieved a countdown LED interruptio

The intersection traffic light has realized the four corners vehicle control, this curriculum designed has mainly realized the parallel connection 8255 pass-along messages and comes the countdown with the light emitter diode, 8253 and 8259 combination matching, have realized the countdown interrupt,

Crossroad traffic lights to achieve the intersection vehicle control, this curriculum design enables parallel interface 8,255 information use led to countdown, and 8,253 portfolio mix, enabling countdown timer interrupt, eventually LED tube changes once per second, ability to traffic lights to simul
