兵乓球比賽 8255 C語言實現

 

1)基本要求

用8個LED發光管(紅黃綠)的來回滾動顯示來模擬打乒乓球時乒乓球在兩邊球檯上的來回運動。比賽雙方用按鈕/開關(雙方各用1個按鈕/開關)的方法來模擬發球與接球,即發球方按動其控制的按鈕/開關/健,球從發球方一側向對方運動(LED發光管從發球方到對方逐個點亮,滾動顯示),當球運動至接球方時,接球方立即按動其控制的按鈕/開關/鍵,“擊球”使球“彈回”發球方一側，如此周而復始，直至在規定的擊球時間內有一方未能完成擊球動作，從而對方得一分，然後繼續比賽。比賽規則可參照一般的乒乓球比賽規則。

要求：

(1)球以每0.5秒滾過1個LED的速度移動;

(2)回球需在球到達後的0.5秒內進行(按下按鈕),否則按失球計;

(3)球未到達提前按下按鈕按失球處理，不起回球作用;

(4)用擴展的4個七段數碼（小鍵盤上）爲雙方記分(每方2個八段碼, ,按10進制計數,初始值00:00,可自行設計顯示及規則)

2)設計提示

球到達接球方後,立即讀接球方的按鈕狀態,若未按則有效(若已按下則按失球計),然後不斷讀此按鈕狀態,直到按下代表“擊球”動作。（採用中斷，可以用同一個按鍵輪流按動識別）。

3)進一步設計要求

(1)在8×8點陣（虛擬大屏）同步顯示球移動情況，設計顯示輸贏球圖形狀態、效果等；移動、擊球等精確（中斷）計時;

(2)通過撥動開關或鍵盤設定改變球移動速度,即每個LED管點亮時間分別爲0.5秒、0.3秒、0.2秒;通過撥動開關或鍵盤設定改變允許擊球時間0.3秒、0.2秒、0.1秒;球移動速度取決於擊球時間,即球移動速度(每個LED點亮時間)在0.2~0.5秒內可變,具體取決於球到達接球方後擊球所花的時間0~0.5秒如花費的時間短則回球後球移動速度快反之回球後移動
