Hi there,

Which Arduino Uno are you using? And what CAN transciever are you using?

I’m guessing that you’re using an Arduino Uno R3 and MCP2515-based CAN adapter, which requires uncommenting line 22 // #define IS_MCP2515, and not // #define IS_ARDUINO_BUILTIN, as this Arduino does not have a built-in CAN peripheral (hence the need for the MCP2515).
