LAUNCHXL-F28379D: PSIM C CODE FOR THE CCS 20.0.1

Hi Aldo,

Is the PSIM code publicly available? Can you link to it if so?

If you have C code but it isn't yet in a C2000/CCS project structure, what you can do is import an empty project (something like an LED blinky project) from our TI Resource explorer and attach the generated C code into your project. TIREX should be available through the file menu in the CCS v20 application and you can point directly to the specific microcontroller device you are using (TMS320F28379D). The example project will all of the necessary linker command files and target connection config files to connect to the LaunchPad. You can use the FLASH build of the project to enable flashing to your device

Regards,

Peter

HI Peter,

Thank you for your advice.

I copied below  the ( esoteric )PSIM generated code, it is basically the configuration of  standard and phase shifted  Pwm modules and ADC .The algorithm code is still to be developped. I guess the include files  have to be imported under the CCS project in some way but I have no knowledge on this.

I finally installed the previous CCS version 8.3.1 which recognizes the PSIM Simcoder generated project and succeeded to import it. and could flash and run the code .

Best Regards

Aldo

Hi Aldo,

For the files reference in the #include, you want to make sure that their file location is included in the include paths in the project properties. This way the compiler and linker can find the file and correctly compile the code. CCS may be able to find the file when you ctrl+click the file name but this may give a false impression if the file isn't found in the project's include paths

Regards,

Peter
