Configure MATLAB coder for Ti C2000 compiler

I have trying to use Ti functions based on driverlib library and running into the saqme issue as the one answered in this post: https://www.mathworks.com/matlabcentral/answers/2035869-how-to-compile-c2000-driverlib-calls-into-an-s-function

After separating the build process between 'MATLAB' and codegen the code generation still uses MinGW to compile the code:

>> mex -setup c

MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.

How can I add the TI compiler to the available compilers and change to default to the one for C2000 products?

Thanks.

Hi,

As per my understanding, you are trying to compile C2000 "driverlib" functions into an S-Function in MATLAB. To use the TI compiler for C2000, please refer to the steps below:

Locate the TI Compiler path, which is generally found under the following path:

C:\ti\ccs\ccs_base\tools\compiler\ti-cgt-c2000_xx.x.x

Register the TI compiler in MATLAB using the following command:

mex -setup C

Use the "coder.updateBuildInfo" by referring to the following MathWorks documentation to explicitly set the TI Compiler inside S-function.

https://in.mathworks.com/help/simulink/slref/coder.updatebuildinfo.html

Invoke the "mex" function with the TI compiler using the following command and ensure that the environment variables are set before running it in MATLAB :

mex -v -f path_to_TI_compiler_cfg my_s_function.c

Hope this helps!

Maneet, after further looking into my issue I see that I am using the correct C2000 compiler.

The errors I have are because the driverlib is using the same MCU resources as controlsuite that the Simulink is using when generating the code for C2000 microcontroller.

Do you have any documentation on how to create MEX functions to control C2000 either using controlsuite or how to add driverlib functions without any collisions.

Thanks.

Hi Valeriy,

To avoid resource conflicts between Simulink-generated code and custom “driverlib/ControlSuite” code, make sure that only one approach configures each hardware resource. Use S-Functions or the Custom Code feature to integrate your code, but coordinate resource usage to prevent collisions.

For more details you can refer to the following documentations:

Integrate C/C++ Code into Simulink - MATLAB & Simulink

Code Generation for Custom Blocks - MATLAB & Simulink

legacy_code - Integrate existing C/C++ code using Legacy Code Tool - MATLAB

Hope this helps!
