Is I2C master to Master communication possible?

Is it possible for an I2C master device to communicate with another I2C master device ?

Thanks

Solution

  • Yes! As long as it specifies that it can do Multi Master operation, then it can communicate with another Master device. There is a clock synchronization procedure that two masters need to perform. To see how that works, read this PDF, section 4.3.1
