add support for adapters USBCANFD 2ch (STM32G473)

[AlekseyMamontov]

Hello,

I am a developer and manufacturer of USB-CAN FD adapters.

I was wondering if you could add the build files for these boards to your project. I have successfully built and tested your project on this hardware today, and everything works perfectly for both the single-channel and dual-channel versions of the adapter.

The performance on the STM32G4 is stable, and the firmware footprint is very compact (~50 KB). I have documented the build process here:

Thank you for this great project!

Best regards,
Oleksii

Hi,

Thank you for reaching out. I am glad to hear you find the project useful.

For adding upstream support for your particular hardware, you first need to add support for the board(s) to upstream Zephyr. Once that support is merged, I'll be happy to review a PR for adding any board-specific overlays needed for CANnectivity.

Hi Henrik,

Got it. Adding support to the upstream Zephyr project seems like a long process, so I’ll probably leave it as is for now ))

I really enjoyed your project because it took very little time to build and get running, even though the Zephyr files themselves are quite heavy!)))

As a token of my appreciation for your work, I would like to send you a gift — one of my dual-channel adapters with your firmware pre-installed. Please let me know if you are interested and where I should ship it. ))

Best regards,
Oleksii
