Can we have multiple 1-wire devices on single pin?

[CuriousOne]

And a side question, can we use 1-wire protocol to communicate between 2 PICs?

[Ioannis]

The idea is to have the PIC as a master device and the PIC to request a communication.

So, with the available commands, it is not possible to make a PIC react as a slave 1-wire device.

You have to write your own code for that.
