Your guide to Controller area network (CAN, CAN-bus)
Controller area network (CAN, CAN-bus) is a vehicle bus standard, which is designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer.Can-bus is a network used in many every-day products consisting of multiple microcontrollers that need to communicate with each other.
CAN (Can Bus) is a message based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment.
Controller area network (CAN, CAN-bus) development started originally in 1983 at Robert Bosch GmbH. This message based protocol was officially released in 1986 at the Society of Automotive Engineers (SAE) congress in Detroit, Michigan. The first CAN controller chips, produced by Intel and Philips, came on the market in 1987. And Bosch published the CAN 2.0 specification in 1991.
Controller area network (CAN, CAN-bus) is one of five protocols used in the OBD-II vehicle diagnostics standard. The OBD standard has been mandatory for all cars and light trucks sold in the United States since 1996, and the EOBD standard, mandatory for all petrol vehicles sold in the European Union since 2001 and all diesel vehicles since 2004.
CAN bus (CANbus) is a Balanced (differential) 2-wire interface running over either a Shielded Twisted Pair (STP), Unshielded Twisted Pair (UTP), or Ribbon cable.
