G'day Lizby,
Rejected DS18B20 temperature sensors are left out in later versions and can be used with an extra timeout. Or try the code below.
' Function TEMPR() and TEMPW() Dallas DS18B20. V6.03.00RC10 Const Pin$="GP14"
Do Print Print "DS18B20 TEMPW(";Pin$;"):"; Str$(TEMPW(Pin$),3,2);" "; Chr$(176);"C" Print "DS18B20 TEMPR(GP14):"; Str$(TEMPR(GP14),3,2);" "; Chr$(176);"C" Print "DS18B20 TEMPR(GP14):"; Str$(TEMPR(GP14,200),3,2);" "; Chr$(176);"C" ' TEMPR(pin [,timeout]) Manual: Ver 6.02.01 Page 200 PicoMite User Manual. Pause 5000 Loop
Function TEMPW(Pin$) Local T1,T2,b,t OneWire Reset Pin$ OneWire Write Pin$,1,2,&HCC,&H44 Pause 80 t=Timer OneWire Write Pin$,1,2,&HCC,&HBE OneWire Read Pin$,2,2,T1,T2 TEMPW = ((T2 And &B111)*256+T1)/16 If T2 And &B1000 Then TEMPW=-TEMPW End Function
