thanks rob
ok there is some test whith this user manip & code
but tests for all arduino boards should be in arduino software without having nothing more than connect to the software
if i make a drone for example
it fly and it fall on the head of someone
even if (s)he is not dead there is a process risk
if what i did is ok the failure is the board
so the warranty will be declared false and the board maker will have to pay
i don't want that

so i repeat the warranty need full checking of arduino boards on arduino software to be legal
i will test everything myself as soon as possible so no problem with me
