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.

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)
What AVR chip you are using? also if you are using WinAVR or any other compiler,are all the I2C ports using same protocols and SCL frequencies? As you know I2c protocols vary very very slightly for some devices
I have done I2C communication using Atmel Microcontroller. Kindly tell me on which microcontroller you want to implement yhis. I will send you code and other details accordingly.
