Arduino HID Project

Header Picture

This project went through a lot of phases and has now reached a new Arduino USB-Core Library with a lot of new functions like extended HID. It also supports HoodLoader2 (version 1 is no longer supported). The idea is to enable enhanced USB functions to almost all 'standard' Arduino boards.
