Arduino: How to get the board type in code

Thanks to the help of Charlie Hanson and jantje I found the universal solution!

Because it is a pity that every Arduino programmer has to go through the same pain to figure out how to get the board name, I will offer my code to the public so everybody can just copy and paste it.

Here it is:

#if defined(TEENSYDUINO) 

    //  --------------- Teensy -----------------

    #if defined(__AVR_ATmega32U4__)
        #define BOARD "Teensy 2.0"
    #elif defined(__AVR_AT90USB1286__)       
        #define BOARD "Teensy++ 2.0"
    #elif defined(__MK20DX128__)       
        #define BOARD "Teensy 3.0"
    #elif defined(__MK20DX256__)       
        #define BOARD "Teensy 3.2" // and Teensy 3.1 (obsolete)
    #elif defined(__MKL26Z64__)       
        #define BOARD "Teensy LC"
    #elif defined(__MK64FX512__)
        #define BOARD "Teensy 3.5"
    #elif defined(__MK66FX1M0__)
        #define BOARD "Teensy 3.6"
    #else
       #error "Unknown board"
    #endif

#else // --------------- Arduino ------------------

    #if   defined(ARDUINO_AVR_ADK)       
        #define BOARD "Mega Adk"
    #elif defined(ARDUINO_AVR_BT)    // Bluetooth
        #define BOARD "Bt"
    #elif defined(ARDUINO_AVR_DUEMILANOVE)       
        #define BOARD "Duemilanove"
    #elif defined(ARDUINO_AVR_ESPLORA)       
        #define BOARD "Esplora"
    #elif defined(ARDUINO_AVR_ETHERNET)       
        #define BOARD "Ethernet"
    #elif defined(ARDUINO_AVR_FIO)       
        #define BOARD "Fio"
    #elif defined(ARDUINO_AVR_GEMMA)
        #define BOARD "Gemma"
    #elif defined(ARDUINO_AVR_LEONARDO)       
        #define BOARD "Leonardo"
    #elif defined(ARDUINO_AVR_LILYPAD)
        #define BOARD "Lilypad"
    #elif defined(ARDUINO_AVR_LILYPAD_USB)
        #define BOARD "Lilypad Usb"
    #elif defined(ARDUINO_AVR_MEGA)       
        #define BOARD "Mega"
    #elif defined(ARDUINO_AVR_MEGA2560)       
        #define BOARD "Mega 2560"
    #elif defined(ARDUINO_AVR_MICRO)       
        #define BOARD "Micro"
    #elif defined(ARDUINO_AVR_MINI)       
        #define BOARD "Mini"
    #elif defined(ARDUINO_AVR_NANO)       
        #define BOARD "Nano"
    #elif defined(ARDUINO_AVR_NG)       
        #define BOARD "NG"
    #elif defined(ARDUINO_AVR_PRO)       
        #define BOARD "Pro"
    #elif defined(ARDUINO_AVR_ROBOT_CONTROL)       
        #define BOARD "Robot Ctrl"
    #elif defined(ARDUINO_AVR_ROBOT_MOTOR)       
        #define BOARD "Robot Motor"
    #elif defined(ARDUINO_AVR_UNO)       
        #define BOARD "Uno"
    #elif defined(ARDUINO_AVR_YUN)       
        #define BOARD "Yun"

    // These boards must be installed separately:
    #elif defined(ARDUINO_SAM_DUE)       
        #define BOARD "Due"
    #elif defined(ARDUINO_SAMD_ZERO)       
        #define BOARD "Zero"
    #elif defined(ARDUINO_ARC32_TOOLS)       
        #define BOARD "101"
    #else
       #error "Unknown board"
    #endif

#endif

You can even put this code into a new header file and #include it into your project.

P.D. If you want to know additionaly to the board also the CPU model, search for the file avr_cpunames.h

note this is a windows mod something similar must exist on linux.

The first is quick and easy. Simply modify the platform.txt files you are using as described nelow. The draw back of this is that you will need to change platform.txt files with each release.

add -DBOARD=\"${build.board}\" to the recipe. This will allow for

   const char boardName[]=BOARD;

Which gives you the string "ARDUINO_AVR_LEONARDO" (for the leonardo) in boardName.

The second way is to switch to a better IDE (like already proposed by others). As the creator of the arduino eclipse plugin I would advice to use the arduino eclipse plugin. In the arduino eclipse plugin you do this as follows: Right click on the project->properties->arduino->tab "compile options" put

-DBOARD=\"${A.BUILD.BOARD}\" 

in the append to C and C++ field.

This will make the code above to compile

Adendum

I wasn't aware you wanted the "nice name". I'm not sure this can be fixed in the platform.txt in arduino IDE. In the arduino eclipse plugin change the fixe above in

-DBOARD=\"${A.NAME}\"

to get the nice name (for the leonardo "Arduino Leonardo") in the define Board.
