Embodiment Construction
[0028] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0029] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0030] As described in the background art, each serial port of the current multi-serial port chip can only process data at the same baud rate, and the application scenarios are single, which greatly limits the application prospect of the multi-serial port chip.

The invention is suitable for the technical field of data communication, and provides a serial port communication method based on the baud rate and a multi-serial-port chip, and the method comprises the steps that a bottom layer configuration module receives first target data of a target serial port; the bottom layer configuration module determines a target bottom layer object corresponding to the target serial port in the plurality of bottom layer objects, wherein the bottom-layer objects are constructed in advance based on an object-oriented principle, each bottom-layer object uniquely corresponds to one serial port, and the serial ports corresponding to the bottom-layer objects are different; the target bottom layer object sends the first target data to a protocol analysis module; the protocol analysis module determines a target protocol object corresponding to the target underlying object in the plurality of underlying objects according to the preset underlying objects and the protocol slots of the protocol objects, wherein the protocol object is constructed based on an object-oriented principle in advance; and the target protocol object receives the first target data. According to the invention, the multi-serial-port chip can process data with different baud rates, and the application scene of the multi-serial-port chip is enriched.
Description
technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a serial port communication method based on baud rate and a multi-serial port chip. Background technique [0002] With the rapid development of computer technology, more and more electronic devices use serial chips for communication. For example, the power modules in electric vehicles and their charging piles will use serial chips for module control and monitoring. As the functional requirements become more and more complex, multi-serial chips are often used. [0003] However, each serial port in the current multi-serial port chip can only process data at the same baud rate, and the application scenarios are single. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a baud rate-based serial port communication method and a multi-serial port chip, which can enrich the application scenarios of the multi-seri...
