hello
Has anyone here programmed anything to convert KWP2000 to CAN?
There are many USB2CAN interfaces available on the market that offer an API, but the problem is that initializing them isn't always straightforward.
Thank you.

I didn't quite understand the question. What do you mean by "initialization"? The initialization of the CAN interface certainly depends on the specific hardware being used, while the KWP2000 part is described in the standard.

Hello.
Basically, I want to implement a KWP2000 protocol using CAN. Unfortunately, this isn't possible with standard interfaces because they only provide complete CAN frames, while KWP2000 is actually a K-line protocol.

Sure, that's possible. Just get the KWP2000 specification and ISO 15765; it explains how to do it!

It's also well described here, and I've already programmed it.
