Abstract: An inter integrated circuit (I2C)-based communication method incudes when an I2C signal is encapsulated into a data packet for transparent transmission, an I2C status is indicated by a first field in a packet header of the data packet. The data packet may have no load part, or the data packet has a load part but the load part is used to carry a slave address, a read/write flag, or I2C data. Because the I2C status is indicated in the packet header of the data packet, the I2C status may be encapsulated in a same data packet together with the slave address, the read/write flag, or the I2C data. In other words, the I2C status may not need to occupy one data packet separately.

Abstract: A fault information transmission method applied to a system including a first device and a second device In the fault information transmission method, when a fault occurs in a first transmission unit of the first device, the first device sends fault information to the second device, where the fault information indicates a fault cause of the first transmission unit; a second transmission unit of the second device receives the fault information, stores the fault information in a storage space, and sends a notification signal to a processing unit of the second device; and the processing unit receives the notification signal, and reads the fault information in the storage space.
