Hi all,
In my system there are 3 MCU's sitting on the same I2C bus. Let us take a scenario where all the 3 MCU's issue a start condition at the same time and all the 3 MCU's issue the same slave address and R/W='1' of all the 3 MCU's.Now MCU1 wants to transmit 01010101 to the slave, while MCU 2 wants to transmit 01100110 to the slave and MCU3 wants to transmit 01001111.Since it is a wired AND MCU2 loses the arbitration , my question is who will win the bus b/w MCU1 and MCU3 becuase both of them transmit a zero at the same time the 3rd bit.
Thanks in advance.
