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.)

If I2C can be implemented, it might be possible to implement SPI, and then implementing USB!

A MAX3421E could be used for the latter (see http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3639 ).

I hope someone will pick this up and starts building a USB hack to the La Fonera

didn’t work for me..tried both the standard two-wire-i2c and lefinnois’ 4-wire-i2c implementation..tested with open-wrt kernel and different i2c-devices..
