Hello, good evening my brothers

I have a Curtis 1238, which I want to extract data through Can Bus with the MCP2515 adapter and an Arduino, but I can't get CAN BUS communication, I've browsed the internet, downloaded and tried a thousand codes but I can't get them, can someone help me?

Thank you brothers!

Nope. But you should verify the bus termination and speed before everything else.

I can enable the can bus protocol.

If you have a scope look at the CAN lines and see if you see signal. High and Low. Some firmwares of the Curtis don't do CAN as I understand it.
