Abstract:
Systems and methods for providing a differentiation of two identical slave devices on a same I2C bus without any hardware (e.g. additional ID pins) or software overhead are disclosed. Each identical slave device is connected to the SDA/SCL lanes by interchanging its SDA/SCL ports. It is up to the slave device to detect its signal connectivity to the SDA/SCL lanes of the I2C bus. The slave devices detect the signal connectivity by interpreting the I2C transfer in normal and interchanged connectivity.
