FTSPARK - CAN protocol

Hi - trying to get setup can stream within ecumaster to receive values from FTSPARK using CAN protocol 2b

There is a manual from fuel tech but it is hard to understand what they are talking about - I thought I know something about CAN,never had issues to set it up - but this gives me a headache

anyone who can help me out?

Thanks

FTCAN protocol packs multiple data values into a single CAN packet, and if a value doesn't fit in the remaining space splits it across multiple packets. It's a massive PITA, I spent some considerable time trying to decode it on a Hardwire PDM and gave up. I doubt there's many CAN implementations out there flexible enough to decode it reliably unless they specifically support it.

FWIW FT also have a simple broadcast packet format that's a fixed single packet format and easy to decode, but it only contains like 15 pre-defined basic values (RPM, ECT etc).

Thanks for quick reply

I have the same feeling

Emupro seems to support can2b protocol but it is still absolutely not straight forward to implement

And also for me hard to understand

Any support would be grateful
