So question is what I have done wrong?
I did not any changes, I have installed latest IDE release 1.5.5
I loaded default example, setup up correct port , DUE programming port and that error occurs
I also tried to use IDE 1.5.2r2 and library from GITHUB manually uploaded into ...arduino/hardware/arduino/sam/library
Also does not work for me...
Does this library work for you guys with DUE? Is there needed some modification?
I have been looking for a solution in the google for 3 hours at least, but it seems nobody has similar problem with IDE 1.5.1 and above.
I am working in Windows 7 64bit system if is it matter.
I can control servo without library of course, but I think that software timer for PPM generation will consume a lot of CPU capacity.
So once more again, thank you for any help. Miro
