Embodiment
Specific embodiments of the invention provide a kind of CCS software desk Implementation DSP based on Texas Instruments (2812,28335 etc. chip) control algolithm code module method, belong to signal processing technology field.The method can be by controlling relevant hardware bottom layer algorithm to DSP, Power Electronic Technique control algolithm is packaged into the api function existing with Lib library file form.
The present invention is directed to the software architecture (being called for short " architecture ") of controlling platform software structure and adopting basic platform part, bottom hardware correlative code is made to standard format, design api function interface, is packaged into Lib library file by api function control algolithm.Conventional power electronics algoritic module is as follows: SVPWM algoritic module, PARK mapping algorithm module, CLARK mapping algorithm module, pi regulator algoritic module, sampling computational algorithm module, digital filter algoritic module etc.By designing corresponding api function interface for these power electronics algoritic modules, and be packaged into lib document form, peopleware can call as required corresponding module and carry out software programming.
In the present embodiment, need set up in advance the software project that generates Lib library file, design corresponding source file and header file, define suitable pattern compiler and path, compiling generates Lib library file; And, utilize the data structure mode of structure, association to carry out method to set up to the input in header file, centre and output variable and correlation parameter.In use, control in software and only need directly the library file of required api function to be called, add corresponding Lib library file and header file parameter, and involved function is stated.
Fig. 1 is the overview flow chart of the software modularity method based on CCS software platform, can draw the general design idea of the method according to its flow process.First, carry out software source code design, the api function that can realize difference in functionality encapsulates and generates Lib library file, and in new systematic control algorithm, calls needed api function, thereby has reached software function realization.By such method, new systematic control algorithm software obtains just can generating output variable after input variable.
Fig. 2 shows the design of programmed algorithm source code and is compiled into the step of Lib library file, i.e. the step based on setting up api function and corresponding Lib library file under CCS software platform.Concrete, first, at CCS software platform, set up in advance new project, namely generate the software project of Lib library file, the output type that defines this Project is Library(.lib) file; Subsequently, set up source file (.c) and the header file (.h) of corresponding api function code, and corresponding pattern compiler and path are set, compiling generates Lib library file.While setting up source file, in api function source file, set up principal function, the function that will realize according to this api function goes to design control algolithm, and principal function can remove to define according to the data type of needed output variable the return type of this function.When setting up header file, if the variable that contains multiple different types of data in output variable in defining variable principal function in api function header file, set up structure, association's data type and can include the variable of multiple different types of data, for the many multivariable control algolithms of needs, input, centre and output variable are carried out to assignment, calculating in the mode of structure, association respectively, and the output variable that function returns can meet calling of other api function.
After complete the design of api function header file and source file, under build option column, carry out the setting of complier and archiver, after having compiled, under adding, the Debug of root directory file finds .lib file, this file has comprised the function of api function, and realizes and calling in can the program below.
