Including a user setup configuration in an Arduino sketch

[daxliniere]

Hey again,
Is it possible to override the values in user_setup.h from the main sketch file? I just updated the library and my sketches all stopped working. I realised that user_setup.h might have been replaced during the upgrade and confirmed this is the case.
To avoid future problems, is there a way I can specify override certain settings from my main sketch? Or perhaps make it look for a different user_setup.h file (from main sketch) ?

All the best,
Dax.

I have the same need. I had TFT_eSPI copied as a local library, but I now want to have it as an external library in platformio.
However, the display type, pins definitions etc. are all dedicated to this project, so user_setup.h belongs more to my specific project rather than to the external library.

[daxliniere]

May I propose that if a definition is found in the main sketch, it is used instead of what's found in user_setup.h? This way existing projects won't be broken.

The Arduino IDE environment hides any #defines within sketches from libraries, presumably to prevent chaos from noobs.

In platformIO the normal approach is to use your platformio.ini file as described here:

Note also that this must not be tampered with!

Hey Bodmer, this link is not working, unfortunately. Has it moved somewhere else?

[Bodmer]

Yes, it is here now.

See here for a work-around that allows the setup file to be included in the sketch:
