You can integrate existing C (or C++) functions, such as device drivers, lookup tables, and general functions and interfaces, into Simulink® models by using the Legacy Code Tool. Use the Legacy Code Tool to specify the name of the S-function, files, and path required for the compilation, and options for the generated S-function.
legacy_code function to
generate an S-function, compile and link the generated S-function, and
create a mask for calling the generated S-function.
Before you can use
legacy_code, ensure that a C
compiler is set up for your MATLAB® installation.
|Use Legacy Code Tool|
Use the Legacy Code Tool to generate S-functions automatically from existing C code.
Incorporate legacy C code using a handwritten C MEX S-function, the S-Function Builder, and the Legacy Code Tool.
Use MATLAB Function blocks to call external C code and control enumeration and bus typedefs.
