Using preprocessor directive

[ssk]

Posted on October 01, 2015 at 14:11

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

      Best regards

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\

Best regards

Erwan
