Usage of Embedded Wizard macros in the generated C-code

Question

In some case it is necessary to get information, defined in Embedded Wizard macros, in the C-code of an application. How to realize this?

Answer 1

In a profile you can define a macro, but macros are not automatically exported as defines in the generated C-code. To get a #define in the generated C-code we recommend the following way:

1. Create a macro in the profile where you want to get a #define in the generated code. For example, create the macro "NTSC" and set its content to "true" or "false" and another macro “MaxNoOfChannels” with the content 3000.
2. Create a new unit e.g. “Configuration“ and get an "Inline Code"-brick from the Gallery into this unit.
3. The inline code can be edited in the editor window. There you can implement your #defines dependent on the EmWi macro contents e.g.:

$if $NTSC
   #define CONFIGURATION_NTSC_ENABLED 1 
$else 
  #define CONFIGURATION_NTSC_ENABLED 0 
$endif

#define CONFIGURATION_MAX_NO_OF_CHANNELS $MaxNoOfChannels
