We use those too at work...rather than buy in a system, we designed, built and has working and installed a iButton entry system
Anything you guys would be ready to share? I am happy with my iButton system apart from the fact that it is not networked with the rest of the house, but a standalone system.
The board we designed is this one:
It wasn't designed for iButton, but rather as a small general purpose controller....but we broke some IO out to a connector and the IO on the SAM7 can be configured for open drain, perfect!
Subsequently we made a small daughter board that plugs in and provides 8 button interfaces that are all "data" isolated from each other.
Board runs FreeRTOS and uses lwIP stack.
Is it a lack of ethernet connectivity that is why your current solution is isolated?
You have PM coming your way julf, I can't post the PDF publically because it contains some data that it shouldn't.
