1、數(shù)字電路實(shí)驗(yàn)報(bào)告猜數(shù)字學(xué)院：班級(jí)：姓名： 學(xué)號(hào)：實(shí)驗(yàn)組號(hào)：一.實(shí)驗(yàn)要求【基本要求】1、 游戲規(guī)則：通常由兩個(gè)人玩，一方出數(shù)字，另一方猜。出數(shù)字的人要想好一個(gè)沒(méi)有重復(fù)數(shù)字的4位數(shù)，不能讓猜的人知道。2、 數(shù)字設(shè)置：通過(guò)4*4鍵盤進(jìn)行4位數(shù)字輸入,在數(shù)碼管（DISP0DISP3）上顯示當(dāng)前所輸入的數(shù)字。通過(guò)設(shè)置確定鍵（BTN1鍵）進(jìn)行鎖定，此時(shí)數(shù)碼管上的數(shù)值消失，同時(shí)用點(diǎn)陣開(kāi)始倒計(jì)時(shí)，即：初始狀態(tài)點(diǎn)陣全亮，然后從右下角開(kāi)始，由右到左、由下到上逐點(diǎn)逐排依次熄滅，間隔時(shí)間為1s，共計(jì)64s。3、 猜數(shù)字：可以通過(guò)4*4鍵盤進(jìn)行4位數(shù)字輸入進(jìn)行猜數(shù)字，且每輸入一位數(shù)字在數(shù)碼管（DISP0DISP3）上顯

2、示當(dāng)前所輸入的數(shù)字，按確定鍵（BTN2鍵）進(jìn)行確認(rèn)，此時(shí)要根據(jù)輸入的這組數(shù)字給出幾A幾B，其中：l A前面的數(shù)字表示位置正確的數(shù)的個(gè)數(shù)，用DISP5顯示l B前的數(shù)字表示數(shù)字正確而位置不對(duì)的數(shù)的個(gè)數(shù)，用DISP4顯示l 如正確答案為 2134，而猜的人猜 5314，則是 1A2B，其中有一個(gè)4的位置對(duì)了，記為1A，而1和3這三個(gè)數(shù)字對(duì)了，而位置沒(méi)對(duì)，因此記為 2B，合起來(lái)就是 1A2Bl 接著猜的人再根據(jù)出題者的幾A幾B繼續(xù)猜，直到猜中（即 4A0B）為止。4、 若數(shù)字正確則顯示猜數(shù)字成功，點(diǎn)陣顯示“”笑臉；若輸入數(shù)字錯(cuò)誤系統(tǒng)仍然處于猜數(shù)字狀態(tài)，點(diǎn)陣顯示“X”，并用蜂鳴器或led閃爍報(bào)警。5、
