Hi,
Ok, now my one wire network is working for a few minutes.
I have put 4+5 together, 3+8 and 6+7, but I have inserted a 150ohm resistor to the data pin of each branch, one branch for one sensor in the middle (1.5m) and one for the star "branch" to the end at 3m.
According to the specification, 150ohm resistor is not suposed to work for the DS2482-X but it's actualy the only way I found to make it works (for a few minutes) whereas without resistor no sensor is found.
Is there a way to modify the DS2482-x configuration register to test diferent PullUp options ?
So the 1 wire is very important for me, it controls solar heating panels and boiler, without this working it's realy a problem.
Thanks to help me to get it working.
