I'm working on a project to use an Uno as 1-wire probe in order to publish some humidity data.
My test network is 10cm long and is driven by a DS2484 at 5v.
If I put a second probe on the network (tested with a DS28EA00), both the DS28EA00 and my Arduino are detected and I'm able to read Arduino's data.
But, I have only the arduino on this network, it is not detected anymore : I can see from its console it's receiving and handles 1-wire RESET signals ... but its response is not seen by the head.
I suspect the Arduino GPIO is too weak to put 1-wire bus low. Do you have any tips for such situation ?
??? My response didn't appeared so ... another try.
I don't need pull-up on the 1-wire side as it's already embedded into the DS2484.
I'm using the same schema as appearing on Maxim's page.
Additionally, it's working with "normal" probes like DS18B20 or DS28EA00
