Adding 1 Wire to the Fonera Router

Viktor over at Karosium has been playing with his Fonera router. Looks like they are charging for the routers now, I got mine when they were still free.  Viktor was able to hack the router to allow him to connect it to 1-Wire devices.

“On the hardware side I opted to use a DS2480B 1-Wire Line Driver chip. This chip is used in the DS9097U adapters so it’s basically the standard in UART to 1-Wire interfacing. I wanted to include fancy things on the board like a software controlled power switch and an activity LED, but in the end I abandoned both. The power switch didn’t work out, and the LED was pretty useless due to the low activity on the bus.”
