求助單片機計時和定時再增加按鍵和跳轉功能，各位，急急急！

ID:198696 · 發表于 2017-5-26 12:58

求助大神，現在這個單片機代碼只實現了計時和定時功能，就key 0，1， 2三個有用，我現在想實現key3（功能待定鍵）按下，就跳轉到自己設定規定時間，再按下key3又回到初始計時顯示，當計時到規定時間，蜂鳴器一直響。只有按下key4整個程序重新開始。以下就是代碼，求大家幫忙加點程序實現我這個功能，愿意送出我全部黑幣，萬分感謝！

你的軟件設定還有問題，注解部分還是亂碼，解決方法：點擊Edit、點擊Colors&Fonts、點擊8051：Editor C Files、右側列表中點擊Text、將右側選項Use Color in Comments前勾選去掉，再試試，正確了在進行編程，否則別人看不懂你做了些什么，就不會幫你修改程序。
