Embodiment 1

[0036] figure 1 It is a schematic diagram of a serial communication system provided by Embodiment 1 of the present invention. The structure of the serial communication system includes a master device 10 and a plurality of slave devices 20. The master device 10 and each slave device 20 are connected by a daisy chain serial Row bus 30 carries out communication connection, and daisy-chained serial bus 30 carries out data transmission through the serial differential transmission mode; Receiving uplink communication data fed back by each slave device 20 for downlink communication data; the slave device 20 is used to receive downlink communication data through the daisy-chained serial bus 30, generate uplink communication data according to the downlink communication data, and feed back uplink communication data to the master device10.

[0037] Wherein, the master device 10 may be used to send control instructions or interaction data to each slave device 20 , so as to control each s...

Embodiment 2

[0044] This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, multiple specific and optional implementation manners are given for communication between the master device and the slave device through a daisy-chain serial bus. Correspondingly, such as figure 1 As shown, in the serial communication system of this embodiment, the slave device 20 may include a start slave device 210, an intermediate slave device 220, and an end slave device 230, wherein the master device 10 is specifically used to: Send downlink communication data to the start-end slave device 210; the start-end slave device 210 is used to receive the downlink communication data sent by the master device 10, perform data processing on the downlink communication data, obtain intermediately processed downlink communication data, and send the intermediately processed downlink data to the intermediate Slave device 220; the intermediate slave device 220 is used to receive interm...

Embodiment 3

[0072] image 3It is a flowchart of a serial communication method provided by Embodiment 3 of the present invention. This embodiment is applicable to the situation where a communication mode between a master device and a slave device is established by using a daisy-chain serial bus. This method can be implemented by a serial The communication device can be implemented by means of software and / or hardware, and can generally be integrated in an electronic device, and the electronic device can be a master device and used in cooperation with each slave device. Correspondingly, such as image 3 As shown, the method includes the following operations:

[0073] S310. Send downlink communication data to each slave device through a daisy-chain serial bus.

[0074] S320. Receive the uplink communication data fed back by each of the slave devices for the downlink communication data through the daisy-chain serial bus.

[0075] Wherein, the daisy-chain serial bus performs data transmissi...

Abstract

The embodiment of the invention discloses a serial communication method, electronic equipment and a storage medium. The serial communication method comprises the following steps: sending downlink communication data to each slave device through a daisy chain type serial bus; and receiving uplink communication data fed back by each slave device for the downlink communication data through the daisy chain type serial bus, wherein the daisy chain type serial bus carries out data transmission in a serial differential transmission mode. According to the technical scheme of the embodiment of the invention, the communication rate of the serial bus can be improved while the bus cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a serial communication method, electronic equipment, and a storage medium. 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. [0003] 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 system...
