STM32CubeIDE adding code to main.c - code disappears

Is there a rule where to put code into main.c so that it stays there permanently? It happended to me now a couple of times that I added an interrupt callback function which suddenly disappeared. Are there areas in main.c where to safely put those?

    Hello @chriskuku​,

    You should add the functions in the User Code section:

    /* USER CODE BEGIN */
(..)
/* USER CODE END */

    Ensure that following option is checked: "Keep User Code when re-generating". In this case, the user sections defined by STM32CubeMX are preserved.

    Note that when upgrading to a new version of STM32CubeMX, make sure to always backup your projects before loading the new project (especially when the project includes user code).

    I hope that this brings some help to you.
