Question

[CubeMX] Where can the template for the generated file "stm32g4xx_it.c" be found?

Hello,

I would like to add some code in the generated file "stm32g4xx_it.c" but I can't find any template.

Does anybody know how persistent code can be added to that file?

I know that there are user code sections but I'm using Simulink to generate code and my code is overwritten by Simulink...

Hi TOtt.1 ,

The template is inside the CubeMX code and can't be probably changed.

For your problem is there solution: Simulink will generate code into separate file and this file will be included into "stm32g4xx_it.c" in the section :

/* USER CODE BEGIN Includes */

#include "simulink_code.c"

/* USER CODE END Includes */

By this solution you can independently generate Simulink code and CubeMX code.

Regards

Igor

Hi Igor,

thank you very much for the solution!

In the meantime I found another solution which also works:

In the STM32 Matlab board support package resides a file with the name "customRoutineProcess.tlc". This tlc file tells Simulink to create the file "stm32g4xx_it.c". If this is used as a 'template' for the CubeMX tool and code is written in the user code section this code is also not overwritten by CubeMX.

BTW: We would appreciate it if ST would proceed with developing the STM32 Matlab board support package!

Regards

Thorsten
