Awesome

Batteries included embedded USB HID library for usb-device. Includes Keyboard (boot and NKRO), Mouse, Joystick and Consumer Control implementations as well as support for building your own HID classes.

Tested on the RP2040 and RP235x, but should work on any platform supported by usb-device.

Devices created with this library should work with any USB host. Tested on Windows, Linux, MacOS and Android.

Note: Managed interfaces that support HID idle, such as NKROBootKeyboardInterface and BootKeyboardInterface, require the UsbHidClass::tick() method calling every 1ms.

Features

• Keyboard - boot compliant keyboard, boot compliant NKRO(N-Key Roll Over) keyboard
• Mouse - boot compliant mouse, boot compliant mouse with scroll wheel and pan
• Joystick - two axis joystick with eight buttons
• Consumer Control - Media control device, generic consumer control device
• Enums for the Consumer, Desktop, Game, Keyboard, LED, Simulation and Telephony HID usage pages
• Support for multi-interface devices
• Support for HID idle and HID protocol changing
• Support for both single and multi report interfaces
• Compatible with RTIC

Examples

See examples for demonstrations of how to use this library on the RP2040 (Raspberry Pi Pico) and RP235x (Raspberry Pi Pico 2).

Road map

• Examples and testing for other micro-controllers such as the SAM D2x family.
• Support for host device remote wakeup
