Anyway.. Thank you :)

Hey guys,

I would really appreciate your help related to 1-wire communication....

Using:
Neuron L513
Mervis
Temperature sensor DS18B20 even with RJ45 connector

I followed the step by step guide mentioned in section of tutorials...finished previous tutorials with success...
and dived into another one with attaching 1 wire devices as follows

I hope that I configured correctly everything... Problem appeared with detecting 1_wire sensor... no sensors were detected .... even when I plug in another one ... doesnt work...
Do you have any ideas about the problem...
Thank you very much for any response..
Josef
