I need some sample code on how to implement a multi master o multi processor
communication either on synchronous serial communication or I2C bus.
I have tried with I2C and I can read and write to eeprom devices successfully. I
don't know or haven't been able to communicate 2 o more AVR
controllers.
The MCPM mode in the other hand is not clear enough in the datasheet. Besides I
haven't found any sample code about communication using this protocol.
I appreciate if you could give me any working piece of code or links to i for
this.
Best Regards,
Edwin

See Atmel web site and saerch for smbus communication.
that's all you need.

Thanks for the pointers.
After finding some I2c Port Expanding ICs I decided to keep with the I2C but no using master/slave multi processor communicaction .
I did many tests with 2 avr trying to figure it out how to transfer data between them. I have no quit yet doing this but I will try it later.
