;PlatformIO User notes:

;It is possible to load settings from the calling program rather than modifying
;the library for each project by modifying the "platformio.ini" file.

;The User_Setup_Select.h file will not load the user setting header files if
;USER_SETUP_LOADED is defined.

;Instead of using #define, use the -D prefix, for example:
