developing custom bord core(esp32 base)

Projects Programming
1

I'm writing a new Arduino custom bord core, it is also using esp32 base device. so I get Arduino-esp32 core and adding my modification for it. I need to access my new function and objects form Arduino default editor(without creating an object in Arduino editor)

Ex- Serial.print() like I want to access Myobject.myMethod.

I create some global object using extern keyword, I can access it from esp32 core main.cpp and other core files
specially I can access my object also main.cpp -> Tasktask -> setup or loop (main programme bind with Arduino editor )

but I can't access it form Arduino editor, it gives error "undefined reference"
I try to find documentation for how to pass editor code to Arduino core, but I can't find it,
anyone have a solution for it or relevant doc please help me

It's not clear to me what your asking. I think you'll have a better chance of getting help if you provide specific details of exactly what you're trying to do.

That doesn't create an object, it declares it. You have to define it as well, in a CPP file somewhere, otherwise you get "undefined reference".

Thanks dear, I want to, when select my bord from Arduino ide, call my core objects and function directly (without creating any objects in arduino editor or include hedders)

like these

but I define it core and I can access in the core
like these

my question is how to access it from Arduino editor without creating an object in editor, (like Serial Object)
