OneWire circuit design & code
Budget: $250 – $750 NZD
A device which has two OneWire data channels on the same microcontroller. One channel will be a slave, which can send data as a normal OneWire slave. The other channel can act as a OneWire master. Ideally this will be run on an ATTINY microcontroller.
The advantage of OneWire is that power and data are transmitted along a single wire, with only a ground return to complete the power and data circuit.
A standard OneWire data bus has a single master and multiple slaves. The core of this design/code request is a module which can act as both a master and slave, but on different data lines. If there is a way to isolate the data from the power so that a single line can power a string of modules that would be ideal.
