Hello,

I want to use a pre-processor directive for conditional compilation. 

I have a piece of code which I want to include when a pre-processor directive is defined. Where to define this in SPC5Studio? Which settings are required for this?

Thanks in advance for your reply.

Mike.

    Hello Mike ,

    You can define in the Platform component  by -D<DIRECTIVE_NAME> in CPP options

    1. I tried using the -D under cpp options. I wrote -D PASS1 and my code contains following statement,

    #if defined(PASS1)

    #define Toggle_Pin() palTogglePad(PORT_B, TICK);

    #endif

    With above option, I am expecting the above code should get enabled when I debug it. But I see that this part of code is disabled as it is not getting the required macro definition. Can you please clarify how to achieve this?

    2. Which document/user guide has this information listed for different build or runtime settings?

    Thanks.

    Mike.

    Hello Mike ,

    CPP Options is for C++ Compiler

    C options is for C Compiler

    please use C Option , generate, and compiler

    the different build / runtime settings are described in SPC5 Property description

    SPC5studio is using the hightec compiler

    there are several documents in this directory

    c:\SPC5Studio\eclipse\plugins\com.st.tools.spc5.tools.hightec.win32_1.0.0.201306281422\hightec\docs\
