Detailed Description

The i2c interface class: Provides i2c and eeprom functionality. A subclass should only have to implement the i2c routines. An eeprom implementation comes for free with the interface.

The eeprom routines are implemented on top of i2c. The built in eeprom implementation only does single byte reads and byte writes over the i2c interface, so it should be portable across multiple eeproms. Override the eeprom routines if this is not acceptable.
