S3C2440-AD應(yīng)用

發(fā)布時間：2011-3-25 14:26    發(fā)布者：techshare
關(guān)鍵詞： AD , S3C2440
使用電位器模擬傳感器，進行模數(shù)轉(zhuǎn)化，將AD值轉(zhuǎn)化為溫度值，實時顯示在LCD上。漢字使用48*48字模，字符使用24*48字模。通過軟件PCtoLCD2002提取字模。這里主要用到ADCCON寄存器。首先要使能預(yù)分頻器，因為太快會沒轉(zhuǎn)化完，所以降低頻率，設(shè)置分頻比，然后是選擇模擬輸入通道。然后啟動AD轉(zhuǎn)換，該位在開始后自動清零，通過ECFLG位檢查是否轉(zhuǎn)化結(jié)束。ADCDAT0低10位用來存放轉(zhuǎn)化來的數(shù)據(jù)。
