DS18B20溫度與讀出數(shù)對應(yīng)關(guān)系

1、精選優(yōu)質(zhì)文檔-傾情為你奉上DS18B20溫度與讀出數(shù)對應(yīng)關(guān)系DS18B20溫度與讀出數(shù)對應(yīng)關(guān)系，讀出的16進(jìn)制數(shù)乘0.0625即為度數(shù)，讀出的16進(jìn)制數(shù)最后一位是小數(shù)，最高位是符號位，負(fù)度數(shù)是F,正度數(shù)是0，如果是只取整度數(shù)最后一位就全人為填上0，下面的數(shù)據(jù)即進(jìn)行了填0處理。1°=0010           2°=00203°=00304°=00405°=00506°=00607°=00708°=00809
