No CAN Communication Rev3 Brain Board

Post by Adrian »

Cant Read or Write CAN Messages to Brain Board.

I have a Rev3 Brain Board, plugged into a adapter board kit for the Nissan Leaf™ Gen 2 inverter.
Currently bench testing, not actually plugged into leaf inverter.

I have 2 Nana Arduino boards with MCP2515 modules successfully sending and receiving CAN Messages.
Receiver not filtering message type.

I have used a CRO to see messages from Arduino sender, but see no messages if I stop sending.

The Brain boards set to default should send udc/pot/tmphs etc every 100ms from what I understand.

Is this correct? Should I see CAN messages with this bench test?

I have had CRO on Bain board JP1 Pin1 & 2 and see my Arduino generated messages getting to this point.

I am not sure what to try next....
