Canbus protocol format
WebNov 18, 2014 · At the CAN protocol level all nodes in a CAN network are equal and make a decision about whether to process a message or not. A "CAN controller" is a higher-level concept; it still needs to examine the message identifier like any other node. Note that "processing" a message is different to the CAN protocol message check and … WebKlipper command messages going from host to micro-controller use the CAN bus id of canbus_nodeid * 2 + 256, while Klipper response messages from micro-controller to host use canbus_nodeid * 2 + 256 + 1. Each micro-controller has a factory assigned unique chip identifier that is used during id assignment. This identifier can exceed the length of ...

WebApr 26, 2024 · CAN bus considers the 11 bit indentifiers to have a higher priority than the 29 bit identifiers (because the two types of "protocol", "11" and "29", can coexist in the same bus). Hence: In the case of a 29 bit extended frame, the RTR bit has been moved to the end of the message so it doesn't play in the priority bitwise arbitration of the 29 ...
