Hi ivan, where did you install the Joystick library?

.

3

you never create a Joystick object...

look at some examples of the library and look for the version of the constructor that may look something like:

Joystick myJoystick(some values);

before setup();

4

I install it at documents

5

Are you using this library: GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library that adds one or more joysticks to the list of HID devices an Arduino Leonardo or Arduino Micro can support.?
If so, you need to create a joystick instance:

Joystick_ Joystick;
6

yes just found out that was the problem
