The AM572x IDK EVM contains multiple I2C buses connected to a master port on the processor. Each bus contains one or more I2C slave devices that must have unique addresses to prevent contention. Table 2-1 and Table 2-2 list the addresses of the I2C slave devices attached to buses I2C1 and I2C2, respectively.
