Problems solved by technology

[0002] The current rapid development of integrated circuits has made processors more and more miniaturized and available resources are more abundant. However, in actual various engineering projects, system design has become increasingly large and complex. Some projects are due to cost Factors such as control often lead to the problem of insufficient processor resources in the end, resulting in the inability to complete the required communication with other processors, thereby replacing the higher-cost processor

Embodiment 1

[0041] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a serial communication control method.

[0042] figure 1 It is the flow chart of the control method embodiment of the serial communication of the present invention, as figure 1 As shown, the control method of the serial port communication in this embodiment may specifically include the following steps:

[0043] 100. If it is detected that the sending end of the processor in the sending state outputs a preset level signal, obtain monitoring information corresponding to the preset level signal;

[0044] In a specific implementation process, during the communication process between any two processors used for serial communication, each processor switches between the sending state and the receiving state, and after the state is switched, the processor in the sending state generates After the communication data is preset, the sending end of th...

Embodiment 2

[0063] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a processor for serial communication.

[0064] The processor used for serial communication in this embodiment may include a storage module and a processing module;

[0065] A computer program is stored in the storage module, and when the computer program is executed by the processing module, the steps of the serial communication control method of the above-mentioned embodiment are realized.

[0066] The processor used for serial communication in the above-mentioned embodiment is used to realize the corresponding method in the above-mentioned embodiment, and its specific implementation scheme can refer to the relevant description in the method and method embodiment recorded in the above-mentioned embodiment, and has the corresponding method embodiment Beneficial effects are not repeated here.

Embodiment 3

[0068] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a serial port communication system.

[0069] figure 2 It is a schematic structural diagram of an embodiment of the serial communication system of the present invention. The serial communication system of this embodiment has at least two processors for serial communication. Among any two communication processors, each processor is in the sending state and receiving Switch between states. Such as figure 2 As shown, this embodiment takes two processors for serial communication as an example to illustrate the technical solution of the present invention. Among them, one processor is the master processor 20 and the other processor is the slave processor 21 . After the two processors switch states, after the processor in the sending state generates preset communication data, control the sending end of the processor in the sending state to out...

Abstract

The invention discloses a serial port communication control method, a processor, a serial port communication system and a storage medium, and the method comprises the steps: obtaining monitoring information corresponding to a preset level signal if the condition that a transmitting end of the processor in a transmitting state outputs the preset level signal different from a normal level signal ismonitored; judging whether the monitoring information meets a preset action condition or not; if the monitoring information meets the preset action condition, executing the action corresponding to thepreset communication data, thereby realizing multiplexing of the sending end of the processor in the sending state, and improving the utilization rate of the processor at a low cost.

Description

technical field [0001] The invention belongs to the technical field of serial communication, and in particular relates to a serial communication control method, a processor, a serial communication system and a storage medium. Background technique [0002] The current rapid development of integrated circuits has made processors more and more miniaturized and available resources are more abundant. However, in actual various engineering projects, system design has become increasingly large and complex. Some projects are due to cost Factors such as control often lead to the problem of insufficient processor resources in the end, resulting in the inability to complete the required communication with other processors, thereby replacing the processor with a higher cost. [0003] Therefore, how to improve the utilization rate of the processor at low cost is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The main purpose o...
