i2c for the fonera


La Fonera’s are getting pretty popular lately. [Lefinnois] hacked his to get i2c working. He used a 75LS05 to adapt the io levels, and some bit banging in the software to pull it off. Now the Fonera can be used for inexpensive remote monitoring via inexpensive i2c devices. Not to mention that this could provide a cheap network interface for various micro-controller projects. (I’m thinking networked thermostat for my new house.)
