AVR Code for I2C port expander - PCA9534

Need someone to create code needed for an Atmel microcontroller to read 8 inputs off a PCA9534 port expander when interrupt is triggered.

Fully commented code is needed so I can learn from it also. Will only be making one milestone payment at the end of the project as it is only a very small project. Please contact me if any more details are needed.

As requested by many of the bidders, the MC will be either a Atmega16A and a Atmega16U4.
Prefered software would be Atmel Studio 6.1.

Umiejętności: Programowanie C, Elektronika, Mikrokontroler

What Atmell MCU you use? I can code this in C and I have some Atmega chips. PCA9534 is unavailable for me, but I can emulate it with some another chip (another Atmega)
