Controller Area Network (CAN) Training
Controller Area Network (CAN) training covers the ISO 11898 standard of choice for automotive manufacturers and Vehicle Applications. Approved for use as an ISO and EPA diagnostic network, its usage continues to grow. Controller Area Network (CAN) training covers the theory, operation and use of the CAN protocol, and its applications in the automotive and other industries.
CAN is the most widely-used automotive bus architecture. The Controller Area Network (CAN) bus is the dominate the automotive industry and the CAN controllers are sold as on-chip peripherals in microcontrollers. Controller Area Network (CAN) physical layer is composed of a twisted pair multidrop cable as specified with a length ranging from 1,000m at 40Kbps to 40m at 1Mbp.
