Hello Manfred,
Thank you for your answer.
I have several profiles in my EW project and want to pass #define statements to my IAR project depending on the profile I choose.
I wan't create new profiles in the IAR-Project because I have already a lot.
Meanwhile I have found a solution. I have added an empty unit "Options" which contains only profile dependent inlines.
In the IAR project I added in my main.c file #include "Options.c". With this I achieved what I wanted.
Best Regards
Giuseppe Mangiameli
