Custom HID support

[GalatanuM]

I cannot find any way of enabling Custom HID that is inside the core https://github.com/stm32duino/Arduino_Core_STM32/tree/main/system/Middlewares/ST/STM32_USB_Device_Library/Class/CustomHID

I am using PlatformIO and I tried a lot of suggested flags, but nothing helped.

Hi @GalatanuM
The link you provide is not used by the core. It is part of the USB Device library that's all.
An implementation of HID for Keyboard and or mouse is provided.
If you want to use the CustomHID you will have to implement it on your side.

I am trying, but failing at the moment :D

[GalatanuM]

Will it be supported in the future?

[fpistm]

Honestly, I don't know.
This is a community project any contributions are welcome.
I also made a call for new maintainer/contributor.
One Idea I have is to add the PluggableUSB API then adding new class/framework should be easiest (TinyUSB?)

[GalatanuM]

I was trying to get TinyUSB working earlier but failed misserably. I was thinking it would be as easy as it is to get it working for STM32CubeIDE, but it was not :D

You could try my library: https://github.com/Levi--G/USBLibrarySTM32
Provides PluggableUSB support and has a nicohood example here: https://github.com/Levi--G/USBLibrarySTM32/tree/main/examples/NicoHoodHid
Implementing a new USB stack is really not easy, it took me 3 years... (not continuous ofc, but with a full-time job...)
