Long 1-wire bus

[Ioannis]

Henrik:

I use one pair for the +5V, two pairs as ground and one pair as ground and signal.

I cannot be very strict on the precise topology the user will make.

You are right about different setup on the cables. Maybe some other configuration work better. It would be best though that we have a specific one for all networks.

Alain:
I did read all these AN and datasheets. The main trick to have long cable is to replace the passive pull up with active one, but this needs to come up with a routine, maybe in assembly, to control all the necessary timing for the pull-upo/pull-down and the 1-wire communication. This cannot be done with the commands OWIN and OWOUT and I am not that good anymore in assembly as I used to be 30 years ago, when I started with PIC controllers.
