This application discloses a switching circuit and communication system. The switching circuit is electrically connected between a first device without a usable serial bus interface and a second device with a usable serial bus interface. The switching circuit includes a controller, a data transceiver circuit, and a bus communication circuit. In response to an enable signal output by the controller, the data transceiver circuit generates a second communication signal with the same logical state as a first communication signal output by the controller and sends the second communication signal to the first device. Alternatively, in response to a third communication signal output by the first device, the data transceiver circuit generates a fourth communication signal with the same logical state as the third communication signal and sends the fourth communication signal to the controller. The bus communication circuit establishes serial communication between the controller and the second device to realize data interaction between them. Through this method, data interaction between a first device without a serial bus interface and a second device with a serial bus interface can be achieved.
