Abstract

The invention provides an interaction method, an interaction device and an interaction system based a serial bus. The interaction method comprises the steps of: receiving a request message sent by a host; sending a response message to the host, and generating a control command word; receiving a control command word reading command sent by the host; and sending the control command word to the host, so that the host can perform corresponding operation according to the control command word. By adopting the interaction method, the interaction device and the interaction system, operation control on the host can be achieved by a slave.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an interaction method, device and system based on a serial bus. Background technique [0002] There are many types of serial buses and their applications are extremely extensive. Almost all electronic devices are more or less involved in serial buses. In some serial buses, such as I2C bus (Inter-Integrated CircuitBus, I2C bus), SPI bus (SerialPeripheralInterfaceBus, serial peripheral interface bus), 1-wire bus (single bus), etc., the device is divided into master and slave . When interacting, the master is in a dominant position, that is, the master can write data to the slave, read data, or control the slave to perform other operations. [0003] It can be seen that in the existing serial bus-based interactive scheme, the slave cannot perform read and write operations on the master or issue other operation commands. Contents of the invention [0004] Th...
