SERIAL-BUS SYSTEM PROVIDED WITH DYNAMIC ADDRESS ASSIGNMENT AND ITS METHOD FOR CONTROLLING THE SAME

A serial communication bus system with dynamic address assignment and its control method are provided in this invention. The system allows the master device to directly assign device addresses to slave devices without the need for additional signals. This assignment is determined by whether the slave device returns a confirmation (ACK) signal, enabling the next address allocation. Slave devices can also obtain unique device addresses through this allocation process. Therefore, with this invention's serial communication bus system and control method featuring dynamic address assignment, existing I2C bus signals can dynamically assign device addresses, facilitating the identification of a plurality of slave devices and preventing address conflicts among them, thereby improving communication transmission.
