Yes, mantoui!
But I can't test using http://www.pjrc.com/teensy/firmata_test/firmata_test.64bit program, becouse window is empty. Only Arduino IDE shows greating string.
And after copying of "Servo" directory from "arm" folder into "sam" folder, when I compile StandardFirmata I get:
/opt/arduino-1.5.1/hardware/arduino/sam/libraries/Servo/Servo.cpp:45: fatal error: avr/interrupt.h: No such file or directory
compilation terminated.
So, we need interrupt.h for sam (Arduino Due)
