Yes, one Arduino setup is what is needed and termination resistors in both ends of the CAN-bus.
I connected as per this: http://productions.8dromeda.net/c55-leaf-inverter-protocol.html


Hey bexander, I'm looking into doing the inverter swap and it seems like I will need to write the resolver ...

Yes, probably a good idea to do the programming with the inverter on the bench. Can be done in the vehicle as well but safer to do it on the bench.


THis worked great. Cost about $25 and with the help of my brother, a programmer, and your file and directions, my motor is running alot smoother ...

HI bexander. THanks for your help so far. I am having a hard time finding the mcp_can file for can communication in the library.
any ideas where to find file or can you send me a copy? thanks a lot and have a great day, steve


This is the one I use:
MCP_CAN_lib-master.zip

Awesome Thanks

Hi and welcome sglassmann! Please do not blindly quote big chunks, but pick the exact sentences you want to reply to. The thread becomes hard to read otherwise.


Im sorry, I had a hard time replying to just the member I was communicating with. If you need to delete the big chunk response to ...

Hi bexander,
Im trying to reset my resolver # using the Arduino pro mini and mcp2515/tja1050. to transmit your code do you only need one Arduino set-up? Can you share a schematic and explain how you connected with the inverter with CAN HI and LO and what file you used with the inverter numbers ...

Hey Thanks for the helpful reply about the resolver code.

Im having a hard time finding the mcp_can.h file in the library. any assistance or a copy of that file would be great. thanks a bunch

Was able to change resolver settings on my Leaf inverter with this information using a Atmega328p (Arduino pro mini) and a MCP2515/TJA1050 module.
Thanks for sharing, Dala!
