An automatic address setting system and method includes a master device, first and second slave devices. Each slave device includes a peripheral interface controller (PIC), a counter, and a pulse generator. When the first slave device is connected to the master device, the pulse generator generates a first pulse signal to the master device and the corresponding counter. The counter sends an address signal to the corresponding PIC as an identification address of the PIC. When the second slave device is subsequently connected to the master device, the pulse generator generates a second pulse signal to the master device, and the counters of the first and second slave devices. The counter sends an address signal to the corresponding PIC as an identification address of the PIC. The counter of the first slave device changes the identification address of the first slave device.
