hello dears..
May anyone helps me to get the code of the ds18b20 on proton ide that will show me the temperature on a graphical lcd?I used this one but it's not working can anyone find the error in this code??

While 1=1
OWrite DQ, 1, [$CC, $44] ' skip ROM search And start temperature conversion
While ORead DQ, 4 = 0 ' check for still busy converting

OWrite DQ, 1, [$CC, $BE] ' skip ROM search And read the temperature
ORead DQ, 0, [SPTemperature.LowByte, SPTemperature.HighByte, Reg_TH,Reg_TL,Reg_Config,Reserved0,Reserved1,Reser ved2,CRC]
Temperature = 0.0625 * SPTemperature ' convert to degrees C
Print At 1,1,@Temperature, "C",

End

Many thanks
