说明：  基于星研开发环境利用8255编写的小小游戏机：1、LED灯初始状态为循环点亮；2、按键和灯是一一对应的状态，如果在灯n（n=1--8）点亮的时候，按键被按下，则游戏成功，所有灯灭。如果按键n(n=1--8)按下时，相应的灯n没有亮，而是其他灯亮， 则游戏失败，所有灯继续处于循环点亮状态。
(Little game based on Star R & D development environment written in 8255: 1, the initial state of the LED lamp light cycle 2 buttons and lights are one-to-one correspondence, the lamp n (n = 1 - 8) pointslit when the button is pressed, the game is successful, all the lights off.
