(First, I'm quit a beginer in microcontroller programmation)
I am using 4 ATMEGA2561 all communicating on the same I2C bus. So they all have the same I2C adress. The problem is, I am obliged to have 2 master (among the 4 atmega) and it cause lots of problem with one microcontroller wich is reading in the same time a sensor in I2C (also on the same bus, there is only 1 I2C port on this micro).
So my question is : Is i possible to define different I2C adress for each microcontroller so that, I can really separate communications and know to who I'm sending data to ?
Thanks a lot for your answer, you would save me !
