CAN Communications
INTRODUCTION
Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry but
has also become popular in the commercial trucking industrial. The CAN bus is primarily used in embedded systems and
is a network technology that provides fast communication among controllers up to real-time requirements, eliminating the
need for the much more expensive and complex technology.
CAN is a two-wire high-speed network system, that is far superior to conventional hardwired technologies to functional-
ity and reliability. CAN is designed for real-time requirements and can easily beat hardwire connections when it comes to
short reaction times, timely error detection, quick error recovery and error repair.
Characteristics of Controller Area Network
•
Is a serial networking technology for embedded solutions
•
Needs only two wires to communicate messages
•
Operates at data rates of 250K and 500K
•
Supports a maximum of 8 bytes per message frame
•
One Bus can support multiple message IDs
•
Supports message priority, i.e. the lower the message ID the higher its priority
