Your original question seemed to be more about I2C code examples. Anyway, I don't see any reason why you can't do what you're asking. The eval board's I2C interface is brought out to a header and you'd just hook that up to the bone's I2C bus (be sure to also connect the boards' grounds together). The eval board doesn't make any assumptions about power so there are no I2C pull-ups on it. If you need to add pull-ups to the I2C lines, be sure to use 3v3 from the bone's header.
While not 100% relevant, I have two I2C posts here <http://andicelabs.com/2013/06/linux-using-i2c-from-user-land/> and here <http://andicelabs.com/2013/07/adafruit7segment/> with simpler examples. -Ron On Monday, September 21, 2015 at 12:13:27 PM UTC-5, Chintan Pathak wrote: > > Hey Ron, > > Your work at andicelabs.com seems fantastic.
