Problems solved by technology

[0005] However, the above-mentioned serial communication system has limitations, for example: only the master device 11 can initiate communication, the slave devices 121 to 121 can only passively wait for the master device 11, and cannot directly communicate and exchange data with each other, etc.

Abstract

The invention discloses a serial communication system and a serial communication method. In a serial communication system in which multiple node devices are connected to form a closed loop using a bus, any first node device is used as a sending end, and at least one second node device is used as a receiving end. The serial communication method includes: starting from the first node device, sequentially setting the bus state of the input terminal of the next-level node device in a closed loop, and sequentially sending communication data to the input terminal of the next-level node device. The serial communication method allows any node device to be used as a sending end or a receiving end, improves communication flexibility, and is simple in communication control, and can improve communication efficiency of serial communication.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a serial communication system and a communication method. Background technique [0002] In electronics, the cost of a complete system is often influenced by its internal interconnection bus structure. Generally, interconnection bus structures are divided into parallel and serial types. A parallel bus or a serial bus generally consists of data lines, address lines, control lines, and the like. Parallel bus design is simple to achieve, easy to achieve a higher communication rate, which has been widely used. However, the parallel communication method requires more signal lines, takes up more chip pin resources and circuit board design space, and generally requires a larger number of devices. Therefore, this method is generally not used in systems with tight pin resources, limited board space, and cost-sensitive systems. Serial bus communication requires only few interconne...
