Looking for pre-processor documentation

Is there a document where the pre-processor is discussed?

Rgds,

Not that I’m aware of, but it’s meant to do pretty much the same as the Arduino Wiring preprocessor.

If you have any specific questions, just ask here :wink:

Thanks.

http://gcc.gnu.org/onlinedocs/cpp/index.html#Top seems to be a good place to start getting to grips wit the subject.

That’s a good resource for the C preprocessor, but I thought you asked about the preprocessor used to turn .ino project files into .cpp files which sometimes messes with your code and stops it from building.
This you’d deactivate with #pragma SPARK_NO_PREPROCESSOR, but this would not stop the C preprocessor to do its job.

No, I just needed the confidence to take my first rather benign steps into this area.
