原理图.doc

要求：通过8只连续排列的发光二极管的依次点亮代表“乒乓球”的运动，中间两个绿灯表示挡板，其余为红灯。再用两个按键模拟左右两个球拍，键按下代表球拍击球。“左拍”按下可使发光二极管从左向右依次点亮，如同“乒乓球”从左向右飞来；“右拍”按下则可使发光二极管从右向左依次点亮，代表“乒乓球”从右向左运动。在游戏过程中，用数码显示管实时显示双方比分。游戏规则如下：
（1）“乒乓球”移动速度是固定的，设定每秒钟移动一位（发光二极管）。
（2）在“乒乓球”移位一次的过程中，进行25次的测试（即每40毫秒一次），查询接球方是否有击球动作。
（3）接球方的击球动作应发生在“乒乓球”到达本方最后一位发光二极管（即点亮）一秒钟时间之内。如接球方在此一秒钟之内按键，则接球成功，接球方得分。“乒乓球”转为相反方向运动。此后，原接球方变为发球方，原发球方变为接球方。游戏继续进行。
（4）如接球方提前或滞后击球，则接球方失误。双方都不得分。这时“乒乓球”熄灭，数码显示管显示双方的比分不变。然后仍由原发球方发球。

程序有些乱，请大家帮我改改，帮我做出完整程序流程图。
希望各位高手帮帮我！
