In my driver header this does not work in vMicro but define correct in Arduino IDE. Any hints ?

// detect Arduino version
#if ARDUINO >= 100
     #include "Arduino.h"
#else
     #include "WProgram.h"
#endif

// determine board type
#if defined(__AVR_ATmega328P__) || defined(__AVR_ATmega168__)
     String boardName = "Arduino Uno or older";
     
#elif defined(__AVR_ATmega32U4__) || defined(__AVR_ATmega16U4__)
     String boardName = "Arduino Micro or Leonardo";
     
#elif defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)
     String boardName = "Arduino Mega";
     
#else 
     String boardName = "Unknown board.  Check wikipedia";

#endif

Well the compiler take the "board" settings from vMicro. It does not take the arduino board makros that enable if elif else defines in the header files.

this snippet works in a "new" ino file and a new header file but not in my old lib header file. Strange

After reinstall and upgrade to latest VS and vMicro it gets the right defines so this seems to be solved.
