Return to Question

By the way I read that Arduino Due can have problems with 1000000 baud rate and I tried different, even significntly less baud rates (for example 115200) with Arduino Due: the result is the same. Also I use level converter for RX2/TX2 pins for Due because it has 3.3v pins but TTLinker device has 5v RX/TX. Maybe the level converter sucks?:) Or maybe I can use 5v serial connection without level conversion? Will it burn my Arduino Due or not?

The code works perfectly on Arduino Mega and allows to independently control servos.

But with Due I have problems: not all commands can be performed. So if compile the code for due only servo ID1 works, but ID2 do not work at all.

So the problem is somewhere here: Arduino Mega works good, but it seems like Arduino Due have no time for on of the operations.
