DS18B20 without pullup resistor

[lyndwyrm666]

How did you manage to get the DS18B20 to work without a pullup resistor?
Is that a feature of the java driver?

My first issue :) Thanks for participating ! You might have actually found an incosistency... I (personally) use a pullup, but you can try a very short cable. I'll update the image as as soon as I find time. For the other GPIO I found a software based (nodejs) solution.

Sorry for the inconvenience!
