Thanks Oliver,
Then I need to define 2 push button in arduino correct ?
and I not understood bad i can test my menu into Arduino serial monitor without lcd before to deploy it with the display,
this I think it's very useful ...
So, I will read the documentation and then I'll start immediately ...
So i think that for the moment I can implement 2 button without problem for be more confortable ... what do you mean ? Then when I'll be able to manage it maybe we can pass to keypad ...
Thanks for your precious support,
Andrea
