設(shè)計(jì)名稱：基于DS1302的數(shù)字時鐘
設(shè)計(jì)者：清河
平臺：STC15W1K16S
硬件部分
數(shù)碼管顯示：位選使用74HC138改為2-4線譯碼、段選使用74HC573提高帶載能力
74HC595靜態(tài)顯示：使用74HC595驅(qū)動一位共陰極數(shù)碼管靜態(tài)顯示當(dāng)前星期
獨(dú)立按鍵：共4個，用于進(jìn)行各項(xiàng)調(diào)整
DS1302：配電池，實(shí)現(xiàn)斷電走時
LED指示燈：指示當(dāng)前所處狀態(tài)和鬧鐘開啟與否
蜂鳴器：使用5V有源蜂鳴器，提供鬧鐘功能
軟件部分
使用定時器0實(shí)現(xiàn)對DS1302數(shù)據(jù)的定時讀取，間隔500ms，以便更新當(dāng)前的顯示值，讀取到的值以全局變量形式儲存
可以考慮使用定時器1實(shí)現(xiàn)數(shù)碼管中間秒指示的閃爍
