@RFPlus I'm not sure what to suggest apart from re-checking the wiring and making sure that RW is grounded.
The display doesn't use any special hardware, it's just simple IO - so if OneWire works, it should definitely go.
If you find out what the problem is, can you let us know? It might be something confusing in the documentation...
