Uavcan gui tool over ethernet ip/udp

  1. No.

  2. I am not aware of any.

  3. I wouldn’t do it this way because SLCAN is more of a quick hack rather than a proper protocol. It is highly inefficient, does not support CAN FD, designed for unframed low-level byte-oriented links, and there is no single commonly supported standard – vendor-to-vendor variability is huge. My educated (and biased, admittedly) opinion is that UAVCAN/UDP is much better suited for the task of transferring CAN frames (or any other real-time data, for that matter) over a UDP/IP network. Just make a pair of publishers/subscribers on either end of the link and exchange messages of type uavcan.metatransport.can.Frame between them. There is also a full-featured exploratory CAN adapter control interface defined but it is more of a network service design excercise than a production-ready solution because it was never deployed in any practical application: On CAN adapters and stateless interfaces

If you decided to go this way, you can use PyUAVCAN on the host side and a somewhat modified Libcanard (or a trivial custom implementation) on the device side.

Edit: added an elaboration about libcanard
