Trellis (Library) do not work on Arduino Zero Pro

[ghost]

Good Morning!

Just test to connect Trellis with Arduino Zero Pro. When I try to compile on Arduino IDE 1.7.3 on a MBP got the compiling errors:

/Users/SierraX369/Documents/Arduino/libraries/Adafruit_Trellis_Library/Adafruit_Trellis.cpp: In member function 'bool Adafruit_Trellis::isKeyPressed(uint8_t)':
/Users/SierraX369/Documents/Arduino/libraries/Adafruit_Trellis_Library/Adafruit_Trellis.cpp:70:36: error: '_BV' was not declared in this scope
return (keys[k>>4] & _BV(k & 0x0F));

For Arduino Leonardo my sketch is compiling well.

yah Zero doesnt have _BV
you migtht be able to
#define _BV(bit) (1 << (bit))
at the top of the file
