CAN (Controller Area Network) is a high-speed multiplex communication protocol for real-time communication in
The CAN specification is generally divided into two layers: a physical layer and a data link layer. In turn, the data link
(1) Standard format frame
(2) Extended format frame
• The standard format frame uses 11-bit identifiers, which means that it can handle up to 2,048 messages.
• The extended format frame uses 29-bit (11 bits + 18 bits) identifiers, which increases the number of messages
• An extended format frame is set when “recessive level” (CMOS level of “1”) is set for both the SRR and IDE bits
