CAN DBC Object Attributes

In CAN DBC, object attributes are additional information that can be associated with objects such as nodes, messages, and signals. These attributes can be used to store information about the object, such as its Message Transmit type, Message cycle time, or Initial value of a signal. There are two types of attributes in CAN DBC, […]

CAN Signal Byte Order: Intel vs Motorola

We know that a CAN message consists of 8 bytes. Each byte consists of 8 bits. Within each byte, the bit ordering is fixed as shown below, where lsb is the least significant bit and msb stands for most significant bit. When the data is transmitted on the bus, low bits of the first byte […]

Signal Multiplexing in CAN DBC

We know that CAN communication uses a non-destructive bit-wise arbitration to control access to the bus, that is, the CAN ID is used for granting access to the bus. Each message has a limited data length. So, to transmit a large chunk of information which is larger than the data length, the concept of multiplexing […]
