Compatibility with Servo.h
Because Servo Library uses the same callbacks of DueTimer, we provides a custom solution for working with both of them. However, Timers 0,2,3,4 and 5 will not Work anymore.
You will need uncommend the line in DueTimer.h in DueTimer folder inside the Libraries folder. Uncomment the following line in DueTimer.h:
#define USING_SERVO_LIB true
