Can remote frame format
WebNov 16, 2024 · There are 5 types of frames in CAN protocol; Data Frame (DF): Carries Data from transmitting node to receiving node. Remote Frame (RF): Some times, a node might want to request some data from another which is made possible by Remote frame. There are two differences between data and Remote frames. WebJun 4, 2024 · The Control Field of an extended message frame, following the 18-bit extended identifier plus RTR bit, has the format of the original CAN 2.0A standard. Bits r1 and r0 are reserved for future use and are always kept at a dominant level. PiCAN 2 - CAN Bus Interface for Raspberry Pi
