WebbThis way it is possible to have on the same I2C bus more than one I2C device with the same fixed part of I2C address. The allocation of I2C addresses is administered by the I2C bus committee which takes care for the allocations. Two groups of 8 I2C addresses are reserved for future uses and one address is used for 10-bit I2C addressing.
