Library doesn't compile on Mega board

[vossilius]

Hi,

thanks for sharing the library. However, I get error trying to compile the example.

Arduino: 1.6.12 (Mac OS X), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
In file included from /[...]/ArduinoBoardManager.h:140:31: error: '__AVR_ATmega1280__' was not declared in this scope
   static const uint16_t CPU = __AVR_ATmega1280__;
                               ^exit status 1
Error compiling for board Arduino/Genuino Mega or Mega 2560.

I get the error with my Arduino Mega 2560 as well as Controllino (which is based on Arduino Mega). Any thoughts?

Thanks!

There is a bug in ArduinoBoardManager.h
It will not compile for ATmega2560 because ATmega1280 and ATmega2560
are combined in the same #elif defined section and when ATmega2560 is defined,
the code attempts to assign the undefined symbol AVR_ATmega1280 to CPU which
causes a compile time error.

The solution is to break the #elif defined section into two sections, one for AVR_ATmega1280
and one for AVR_ATmega2560 and change the CPU assignment in the AVR_ATmega2560 define to
CPU = AVR_ATmega2560
