Probably a minor thing, but I'm only weeks into Arduino use and the current way to install libraries seems to be to use the library manager to install the ZIP directly.

This works fine although I really wish they still supported the "copy and paste" version as that would make it easier to develop and debug, I suspect.

Anyway, I got it loaded so I can give it a go now. Why does USB have to be such a right royal pain the in butt?!

I'm working on a handheld using the pro micro and I need at least two more buttons.

Hello everyone!

I'm in need of some assistance with a custom Arduino Leonardo game controller I've been working on. I've utilized the library here to set up my controller. It's functioning perfectly when tested on the Windows gamepad settings—every button press and joystick movement is detected without any hiccups.

However, I've hit a snag with Recalbox on my Raspberry Pi 4B. While the system does recognize the controller as a Leonardo and allows me to use the joystick to navigate the Recalbox menu, none of the buttons are being detected within the controller configuration menu.

Has anyone experienced a similar issue, or can offer any insights into why this might be happening? Your help would be immensely appreciated to get my custom controller fully operational with Recalbox.

Thank you in advance!

Here is my arduino code:

In the readme the setters for the axes all expect an uint8_t but that should be an int8_t.

Hi, is possible to add more than 16 buttons?

I used this site: https://gamepad-tester.com/

and validated everything works - which (after having no luck with the alternatives) was a wonderful surprise. Of course, now that means I have no excuses not to build the hardware I'd promised my little trainee. Drat and triple drat!

Programmed my arduino Leonardo on my Linux machine and it works as a gamepad, however it doesn't recognize on my Mac.
