    NVIC001 Migration to INTERRUPT App in Dave 4

    I am moving a project from Dave 3 to Dave 4 and I am having an issue when remodelling the behaviour of the NVIC001 app of Dave 3 to the INTERRUPT App of Dave 4.
    In Dave 3 the generated source code of the NVIC001 app implemented the IRQ handler and called a user defined function. I have used this functionality to call a method which is part of a library:
    Code:
    //in NVIC001.c :
    void IRQ_Hdlr_57(void)
    {
       /* <<<DD_NVIC001_non_API_1>>>*/
      DBG002_FUNCTION_ENTRY(APP_GID,NVIC001_FUNC_ENTRY);	   
      /* Calling user defined Event handler*/
      MyLibraryFunction(); 
      DBG002_FUNCTION_EXIT(APP_GID,NVIC001_FUNC_EXIT);
    }
    The new INTERRUPT app copies the name of the user defined function and uses it in the context of a macro. Calling a function of a prebuilt library is not possible anymore without using a wrapper routine as the IRQ handler may vary in the several projects which use the library:
    Code:
    //in interrupt_extern.h :
    #define MyLibraryFunction IRQ_Hdlr_57
    I would like to suggest a modification of the INTERRUPT app so that using a macro for mapping the user interrupt handler is avoided. If the generated source code of NVIC001 is reused, there will be another advantage: the users will get errors during compile time when they forget to implement the user interrupt handler instead of wondering why the misspelled/excluded from build/... function is not entered.
