How to Manage Priority and Determine Node Count for CAN Bus Using Arduino Uno and MCP2515?
hello guys need Help, i have a project of realizing CAN bus, to achieve it i use two Arduinos uno and two CAN modules, every arduino is attached to MCP2515 , i did the communication like pressing a push-up button in the transmitter side to control a led in the receiver side.
i need help on managing the priority (like ABS has priority than any action like windshield wiper) how much Nodes(MCP2515) do I need? and how can I manage the priority of actions? @Middleware & OS

Hi, The number of MCP2515 nodes you need depends on the number of devices you want to connect and control. Each node corresponds to an Arduino with an MCP2515 module.
You can manage Priority by the Indentifier in CAN frame, lower value has high priority
@ShreeshaN can you clarify more with examples please
