基于單片機(jī)數(shù)碼管顯示的鬧鐘
/***********************************************************
名稱：基于AT89S52數(shù)碼管系統(tǒng)測(cè)試程序
要求：流水燈電路測(cè)試，數(shù)碼管電路測(cè)試，獨(dú)立式鍵盤電路測(cè)試，蜂鳴器電路測(cè)試
作者：劉楊
時(shí)間：2012年12月12日
電路描述：S1到S8一鍵一功能;P3口連接LED流水燈；數(shù)碼管驅(qū)動(dòng)電路采用74HC573；P1口連接獨(dú)立式鍵盤；P0口，P2口分別控制數(shù)碼管位和段；
