Gamepad with PSP Stick on Arduino Script

[Laen]

Hi want to Build a GB Zero with a Raspberry Pi.
How i build an solder it is Clear to me.

But the Arduino Script thing is not my Thing.
I want to Use the Arduino Leonardo as A USB Gamepad.
When i understand Correct it must connect with the usb Cable on the Pie USB.

All Buttons and the PSP Analog Stick musst Solder on die Arduino.

But the Script is my Problem.

I found This one in the Forum

Is this Ok or is there A better one?


The One that i found on a German Website gives me an error when i compile it.

ok thx i dont knew that site.

I think i must use the code for 6 button when i want L/R1 and L/R2
