%% Integrate External C++ Object Methods % Integrate legacy C++ object methods by using the Legacy Code Tool. % % With the Legacy Code Tool, you can: % % * Provide the legacy function specification. % * Generate a C++ MEX S-function that calls the legacy code during simulation. % * Compile and build the generated S-function for simulation. % * Generate a block TLC file and optional rtwmakecfg.m file that calls the legacy code during code generation. % % Copyright 1990-2015 The MathWorks, Inc. %% Provide the Legacy Function Specification % Functions provided with the Legacy Code Tool take a specific data % structure or array of structures as the argument. The data structure is % initialized by calling the function legacy_code() using 'initialize' as the % first input. After initializing the structure, assign its % properties to values corresponding to the legacy code being integrated. % For detailed help on the properties, call % <matlab:legacy_code('help') legacy_code('help')>. The % definition of the legacy C++ class in this example is: % % class adder { % private: % int int_state; % public: % adder(); % int add_one(int increment); % int get_val(); % }; % % The legacy source code is in the files % <matlab:rtwdemo_lct_util('edit','rtwdemo_lct_src/adder_cpp.h') adder_cpp.h> and % <matlab:rtwdemo_lct_util('edit','rtwdemo_lct_src/adder_cpp.cpp') adder_cpp.cpp>. % rtwdemo_sfun_adder_cpp def = legacy_code('initialize'); def.SFunctionName = 'rtwdemo_sfun_adder_cpp'; def.StartFcnSpec = 'createAdder()'; def.OutputFcnSpec = 'int32 y1 = adderOutput(int32 u1)'; def.TerminateFcnSpec = 'deleteAdder()'; def.HeaderFiles = {'adder_cpp.h'}; def.SourceFiles = {'adder_cpp.cpp'}; def.IncPaths = {'rtwdemo_lct_src'}; def.SrcPaths = {'rtwdemo_lct_src'}; def.Options.language = 'C++'; def.Options.useTlcWithAccel = false; %% Generate an S-Function for Simulation % To generate a C-MEX S-function according to the description provided % by the input argument 'def', call the function legacy_code() again with the % first input set to 'sfcn_cmex_generate'. The S-function calls the legacy % functions during simulation. % The source code for the S-function is in the file % <matlab:rtwdemo_lct_util('edit','rtwdemo_sfun_adder_cpp.cpp') rtwdemo_sfun_adder_cpp.cpp>. legacy_code('sfcn_cmex_generate', def); %% Compile the Generated S-Function for Simulation % After you generate the C-MEX S-function source file, to compile the S-function % for simulation with Simulink(R), call the function % legacy_code() again with the first input set to 'compile'. legacy_code('compile', def); %% Generate a TLC Block File for Code Generation % After you compile the S-function and use it in simulation, you can call the function % legacy_code() again. Set the first input to 'sfcn_tlc_generate' % to generate a TLC block file that supports code generation through Simulink(R) Coder(TM). % If the TLC block file is not created and you try to generate code for a model % that includes the S-function, code generation fails. The TLC block file for the S-function is: % <matlab:rtwdemo_lct_util('edit','rtwdemo_sfun_adder_cpp.tlc') rtwdemo_sfun_adder_cpp.tlc>. legacy_code('sfcn_tlc_generate', def); %% Generate an rtwmakecfg.m File for Code Generation % After you create the TLC block file, you can call the function % legacy_code() again. Set the first input to 'rtwmakecfg_generate' % to generate an rtwmakecfg.m file that supports code generation through Simulink(R) Coder(TM). % If the required source and header files for the S-function are not % in the same folder as the S-function, and you want to add these % dependencies in the makefile produced during code generation, generate the rtwmakecfg.m % file. legacy_code('rtwmakecfg_generate', def); %% Generate a Masked S-Function Block for Calling the Generated S-Function % After you compile the C-MEX S-function source, you can call the function % legacy_code() again. Set the first input to 'slblock_generate' % to generate a masked S-function block that is configured to call that % S-function. The software places the block in a new model. You can copy % the block to an existing model. % legacy_code('slblock_generate', def); %% Show the Generated Integration with Legacy Code % The model <matlab:rtwdemo_lct_cpp rtwdemo_lct_cpp> % shows integration with the legacy % code. open_system('rtwdemo_lct_cpp') sim('rtwdemo_lct_cpp')
