標(biāo)題: 單片機(jī)八位競(jìng)賽搶答器 仿真 源碼 原理圖 文檔下載
以單片機(jī)為核心，設(shè)計(jì)一個(gè)8位競(jìng)賽搶答器：同時(shí)供8名選手或8個(gè)代表隊(duì)比賽，分別用8個(gè)按鈕S0～S7表示。
                                       
    1.設(shè)置一個(gè)系統(tǒng)清除和搶答控制開關(guān)S，開關(guān)由主持人控制。    2.搶答器具有鎖存與顯示功能。即選手按按鈕，鎖存相應(yīng)的編號(hào)，并在優(yōu)先搶答選手的編號(hào)一直保持到主持人將系統(tǒng)清除為止。
    3.搶答器具有定時(shí)搶答功能，且一次搶答的時(shí)間由主持人設(shè)定（如30秒）。當(dāng)主持人啟動(dòng)“開始”鍵后，定時(shí)器進(jìn)行減計(jì)時(shí)，同時(shí)揚(yáng)聲器發(fā)出短暫的聲響，聲響持續(xù)的時(shí)間為0.5s左右。    4.參賽選手在設(shè)定的時(shí)間內(nèi)進(jìn)行搶答，搶答有效，定時(shí)器停止工作，顯示器上顯示選手的編號(hào)和搶答的時(shí)間，并保持到主持人將系統(tǒng)清除為止。
    5.如果定時(shí)時(shí)間已到，無人搶答，本次搶答無效，系統(tǒng)報(bào)警并禁止搶答，定時(shí)顯示器上顯示00。
