Yes, the sender and receiver example is working fine. I’ve already tested it successfully. I actually have two Arduino Megas and one extra MCP2515 module as well. Earlier, when I tried setting up communication, it wasn’t working properly, so I bought the extra hardware just to be sure.
Now I have enough components to create a 3-node CAN bus setup, which gives me a good opportunity to run some multi-node experiments and explore the protocol more deeply.
