ds18s20 reads incorectly

[EarlyBird2]

these two lines are commented out?

' SignF = Positive 'Sign is +
' TempF = ((TempC * 18) / 10) + 3200 'Convert from C to F

so I guess you will get 0 deg F

Steve-
Dunno what I had thought I was looking at, but when I un-commented those other lines, I now get correct readings!
This is now what seems to be working:
BTW, going to be in your neck of the woods this Wednesday, 2 days in London, then take a boat out from South Hampton on a cruise through the Baltics.
Thanks for pushing me in the right track!
Regards,
Steve

It is Wednesday you are in England the weather is cold, wet and windy. I am so sorry but what do you expect in England on a summers day.

Have a nice cruise to the Baltic.
