AUTOSAR CANIF

  • Transmit request services: The CANIF’s transmit request function CanIf_Transmit() is a common interface for upper layers to transmit PDUs on the CAN network. The upper communication layer modules initiate the transmission only via the CAN Interface module’s services without direct access to the CANDrv.
  • Transmit confirmation services: If a previous transmit request is completed successfully, the CANDrv notifies it to the CanIf by the call ofCanIf_TxConfirmation(). When callback notification CanIf_TxConfirmation() is called, the CANIF shall identify the upper layer communication layer , which is linked to the successfully transmitted L-PDU, and shall notify it about the performed transmission by call of CANIF’s transmit confirmation serviceUser_TxConfirmation()
  • Reception indication services: This service indicates a successful reception of an L-PDU to the upper layer module after passing all filters and validation checks
  • Controller mode control services: The CAN controller status may be changed at request of the upper layer by the calling of CanIf_SetControllerMode() service. The request is validated and passed by the CanIf via the CanDrv API to the addressed CAN controller
  • PDU mode control services: CanIf_SetPduMode() service sets the requested mode at the L-PDUs of a predefined logical PDU channel.
