USB 2 CAN-FD

[dav1]

Hi,

Are there any implementaions of a raw USB to CAN FD adapter running on the LPC 5x series?
i.e. host-side runs on Linux, C, socket or python/libusb library.
lpc just acting as a packet relay, like a USB2UART adapter but for CAN-FD

I guess your combination would be hard to find, at least as free source.

CAN adapters for PCs do exactly the thing you ask for, but usually commercial products and closed source. And perhaps not even Cortex M based.

Hi dav1

I would suggest you refer AN12646. demo code is attached.

Besides, we also have CAN-FD demo code and SDK package(usb semo and CAN demo are included separately). You can download here

Have a nice day

Frank, yes, the "CAN world" is definitely different, 20x price for basically the same as any UART/RS-485 serial-adapter that is basically same.

Jun, many thanks for the link. I think we can use it as a base. You don't happen to have some demo with CAN-FD over USB?

Hi Dav

Yes, you can use AN12646 as base, referring CAN-FD demo and SDK I recommended as reference if needed.

Unfortunately, we don't have  demo with CAN-FD over USB.

Have a nice day,
