Anyway, i reached a good point. Now i only have the two joystick and two leds (that will be used as output devices), in future i'll place some buttons and such.
So, i tested the board by connecting the two leds to the two potentiometer of the right joystick, and magically it all worked at first try! I planned the board with great care :)
So, before i'll post some pictures, here's the video!
