Description
Technical field
The present invention relates to car communication technique fields, more specifically refer to that work is intervened in a kind of general Can communication of car
The microcomputer development method of tool.
Background technique
Currently, the communication between bus industry components and its control program, are substantially and rest in supplier's hand.Especially
It is imported components, and domestic factor at all can not adjust the logic of software.Once being communicated between components
The unmatched situation of logic, this just needs to be coordinated by main engine plants different components manufacturers and changes communications protocol, since producer matches
The problem of conjunction, the solution time is often long, deals with relatively complicated.
Although host computer communication factory can also be designed simple control logic by oneself and be asked to intervene the communication of components
Topic, but traditional mcu programming is used to propose more harsh requirement to engineer's technical ability of in-situ processing problem.
Summary of the invention
The present invention provides a kind of microcomputer development method of general Can communication intervention tool of car, and main purpose is
Overcome in existing car Can bus communication, the place of communication problem on obstacle caused by communications protocol mismatches between different components
Manage the disadvantages of cumbersome, the processing time is longer.
The present invention adopts the following technical scheme:
Based on the microcomputer development method of the general Can communication intervention tool of car, include the following steps:
(1), user carries out Simulink mould using the library model of Can communication intervention tool under Matlab/Simulink environment
Type modeling；
(2), Simulink code building environment is configured, the Simulink auto-building model code that user is built；
(3), calling presets microcomputer development environment Keil uVision5 after generating code, by the code automatically generated and in advance
First designed bottom layer driving code is done integrated, forms a compileable engineering duty；
(4), the engineering duty of automatic compilation step (3), direct programming enter single-chip microcontroller.
Further, which is the controller unit based on STM32F4 family chip.
Further, Simulink model modeling specifically includes in above-mentioned steps (1): configuration control unit and Simulink
Input/output relation, design control logic between input domain output, and change control logic into Simulink environment
Simulating, verifying work.
Further, the code generated in above-mentioned steps (2) is * .C file and * .H file, during generating code
The prefabricated function in hook file is called, the code after generation is integrated into the exploitation environment of STM32.
Further, above-mentioned steps (4) think the engineering of step (3) to be translated as * .bin file, are passing through STM32 tune
Examination device programming enters single-chip microcontroller.
Preferably, above-mentioned STM32 debugger is ST-LINK or J-Link.
By the above-mentioned description of this invention it is found that compared to the prior art, the present invention has the advantage that
The microcomputer development method of the invention, electric-control system commissioning staff only need to press different signals under simulink environment
Certain logic is combined, so that it may be directly generated control program, can quickly be solved each components communications protocol of car and mismatch
Failure problems, substantially reduce failure and solve the time, and electric-control system commissioning staff is without grasping microcomputer development ability,
Substantially reduce its skill requirement to live embedded system development.
Specific embodiment
Illustrate a specific embodiment of the invention below.In order to fully understand the present invention, many details are described below, but
To those skilled in the art, the present invention can also be realized without these details.For well known component, method and process,
It is not described in detail below.
Based on the microcomputer development method of the general Can communication intervention tool of car, include the following steps:
(1), user carries out Simulink mould using the library model of Can communication intervention tool under Matlab/Simulink environment
Type modeling.
(2), Simulink code building environment is configured, the Simulink auto-building model generation that user is built
Code；
(3), calling presets microcomputer development environment Keil uVision5 after generating code, by the code automatically generated and in advance
First designed bottom layer driving code is done integrated, forms a compileable engineering duty；
(4), the engineering duty of automatic compilation step (3), direct programming enter single-chip microcontroller.
The development approach of the single-chip microcontroller is the controller unit based on STM32F4 family chip.
Simulink model modeling specifically includes in above-mentioned steps (1): the input of configuration control unit and Simulink are defeated
Relationship out designs control logic between input domain output, and changes the simulating, verifying of control logic into Simulink environment
Work.
