Re: Picbasic pitanja za sve sto mi nije jasnoCode:
Temperature = (((Temperature >> 1) * 100) - 25) + (((Count_Per_C - Count_Remain) * 100) / Count_Per_C)
Temperature = (((Temperature >> 1) * 100) - 25) + (((Count_Per_C - Count_Remain) * 100) / Count_Per_C)
Temperature >> 1
Ovime se vrsi pomeranje (siftovanje) promenljive Temperature u desno za jedno binarno mesto tako da 21 postaje 20 .. i tako redom. Time je dobijena celobrojna vrednost temperature.
Count_Per_C - Count_Remain
sluzi da se dobije decimalni deo temperature sa vecom rezolucijom od same rezolucije DS1820 senzora (ja vise volim DS18B20 posto ima vecu rezoluciju - programabilno 9, 10, 11 ili 12 bita)
Evo ti i jedan slican/malo drugaciji program sa 2 komada DS18B20
