Hello Guys,

I'm pretty new to Arduino...

I have built a ButtonBox using an Arduino Pro Micro.  
I use 4 two way toggle switches with a spring return to off and 8 normal push buttons.

The sketch is from here: [GitHub - AM-STUDIO/32-FUNCTION-BUTTON-BOX](https://github.com/AM-STUDIO/32-FUNCTION-BUTTON-BOX)

This is the video: [MAKE THIS BUTTON BOX | 32 FUNCTION w ENCODERS - YouTube](https://www.youtube.com/watch?v=Z7Sc4MJ8RPM)

Problem:

I have downloaded a sketch and installed all the librarys.  
The Joystick library is just downloaded from the IDE-Software because I didn't get this zip into my IDE:

> **[GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library that adds one...](https://github.com/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. - GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library tha...

I know I have to define the buttons...

Now I get two different errors:

'Joystick\_' does not name a type and expected unqualified-id before '.' token

Could someone help me to solve those Problems, please?

Error:

I have a picture attached.

The error message most probably means that you haven't installed that library, at least not correctly.

As usual in most of such cases, your message at the end tells you that you have _two_ (or more) joystick libraries installed. The compiler "decided" to use a different library, not the one you intended to use.

Hi guys,

Thanks for your fast answers.  
I will try this. : )

I tried it.  
Looks like it solved the joystick problem.  
But now I still get the expected unqualified-id before '.' token.

What can I do about that?

Cheers  
Luis

When you are asking questions about error messages, you have to provide the exact line of code that triggered the error. Where is that information?

I think I got it. 🙂

It looks like it just was the wrong library...

It has to be thisone for the sketch:[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.](https://github.com/MHeironimus/ArduinoJoystickLibrary)

Thanks for helping me out!
