Minimal I2C for the New AVR Microcontrollers
This article describes a set of minimal I2C routines for the new 0-series and 1-series ATtiny and ATmega microcontrollers. They allow any of these processors to act as an I2C Master and connect to I2C peripherals. As an example of their use I've designed a digital clock circuit based on...
