[0002] In automotive electronics and embedded systems, CAN (Controller Area Network) communication is widely used in vehicle networks. In order to achieve effective communication between different electronic control units (ECUs), engineers usually use CAN communication matrices to define and describe various signals and messages. After network engineers have sorted out the contents of the CAN communication matrix, they usually publish it through Execl and dbc files, while other engineers view execl files through office and dbc files through other tools, and finally complete code modifications through the code compilation IDE they are familiar with.
[0003] The existing technical solution is mainly completed by engineers to add or change the modification. The process is summarized as follows: according to business needs, network communication engineers update and release a version of the CAN communication matrix file; the bottom software engineer compares the old and new versions of the CAN communication matrix file and finds the differences; the bottom software engineer completes the variable definition, sending table and receiving table modification based on the differences. There are the following disadvantages:
[0004] Differences are difficult to find. The CAN communication matrix has certain rules, but there is uncertainty in the content of the CAN communication matrix file, such as the order of CAN message placement, the adjustment of CAN message content, etc., which greatly increases the difficulty of finding differences and is prone to omissions. Manually adjusting the code is prone to errors. Even if engineers can find all the differences, there is still a large risk of errors when manually modifying the engineering code. The amount of content adjusted each time the CAN communication matrix is uncertain, which increases the complexity and error rate in the manual modification process. The construction period is long and time-consuming and labor-intensive. The existing technology mainly relies on manual inspection and modification, resulting in low work efficiency. Each CAN communication matrix adjustment requires engineers to perform a lot of manual operations, which consumes a lot of time and energy. Summary of the invention

Figure 1 As shown, combined with Figure 2As shown, the method for parsing and generating code of the CAN communication matrix according to the embodiment of the present application includes the following steps:
[0038] S101: Run the executable file to parse the CAN communication matrix file in the CAN communication matrix update directory to obtain the content of the CAN communication matrix file.
[0039] The CAN communication matrix file is pre-stored in the CAN communication matrix update directory. Specifically, in a specific example, before running the executable file and parsing the CAN communication matrix file in the CAN communication matrix update directory to obtain the CAN communication matrix file content, it also includes: publishing the updated CAN communication matrix file and storing the CAN communication matrix file in the CAN communication matrix update directory.
[0040] After storing the CAN communication matrix file in the CAN communication matrix update directory, running the executable file, parsing the CAN communication matrix file in the CAN communication matrix update directory, and obtaining the CAN communication matrix file content, including: running the executable file, parsing the CAN communication matrix file from the CAN communication matrix update directory, and extracting the CAN communication matrix file content from the CAN communication matrix file. In this example, the communication matrix file content at least includes the definition of CAN messages and signals.
[0041] For example: after the network engineer finishes organizing the CAN communication matrix content, the CAN communication matrix file is usually published by email or other transmission methods. Then, the development engineer (such as the underlying software development engineer) copies the CAN communication matrix file in excel and dbc format published by the network engineer to the update directory, that is, to the pre-agreed CAN communication matrix update directory. That is, put the published CAN communication matrix file into the specified directory, that is, the engineer places the updated CAN communication matrix file in the specified directory. In a specific example, the directory is usually the matrix_files folder of the same level directory.

After running the executable file, the CAN communication matrix file placed in the matrix_files directory will be automatically parsed, and the content of the CAN communication matrix file will be parsed, such as extracting the definition of CAN messages and signals. Then, based on the extracted CAN message and signal definition, the code is automatically generated, such as the code written in C language. The engineering code includes but is not limited to variable definition, sending and receiving definition and logic code.
[0045] S103: If no exception occurs during the running of the executable file, then after the engineering code generation operation is completed, an engineering code file is generated in the code generation directory.
[0046] In one embodiment of the present application, if no exception occurs during the operation of the executable file, an engineering code file is generated in the code generation directory after the engineering code generation operation is completed, including: determining whether an exception or error occurs during the operation of the executable file; if not, storing the generated engineering code in the form of an engineering code file in the code generation directory.
[0047] That is to say, a code file written in C language is generated in the specified directory. If no exception or error occurs during the running process, the corresponding C code file will be generated in the generated folder of the same directory.
