Hello,
I tried to get the STM32 code up and running, but I already struggle with getting it compiled (Arduino IDE).

There are two includes mentioned, where I am not sure, where to find them:
#include <USBComposite.h> #include <Button.h> // https://github.com/JChristensen/Button

When checking https://github.com/JChristensen/Button, there is file listed in the src-folder, called "JC_Button.h". Is it this one? So I just need to rename it?

But where might I find the USBComposite.h?

Thanks a lot for your help.
