How can I use the CAN bus on the ardupilot? I read the documentation regarding the CAN mode and the only information I gathered was that the CAN-address is fix and can’t be changed (the link Here 2 CAN Mode Instruction - CubePilot). I am also a little perplexed regarding the CAN bus because it uses a 4p cable like a i2c.
CAN and I2C are 2 completely different protocols. You can google for more information.
If you are referring “CAN node id” as “address”, it can be changed as parameters.
