11 CANbedded LIN Integration API (excerpt) Initialisation vuint8 LinInitPowerOn (void); // LIN stack initialisation Tasks void LinFastTimerTask (void); // Header/Response Timeout void LinSlowTimerTask (void); // BusIdle Timeout tscheduletaskaction LinScheduleTask (void); // Master only Interrupts void l_ifc_rx (void); LIN Master Scheduling void LinSetScheduleTable (vuint8 bschedtblhndl, vuint8 bschedtblentry); Slide: 11/25

12 CANbedded LIN Integration API (excerpt) Network Management vuint8 LinStart (vuint8 bwakeupreason); Internal or external wake-up of the LIN bus with or without sending a wake-up frame void ApplLinWakeUp (void); Callback on wake-up vuint8 LinStop (void); transmission of a sleep-mode frame (only Master) void ApplLinBusSleep (void); Callback on transit to sleep-mode Error Handling void ApplLinProtocolError (vuint8 error, tlinframehandletype vmsghandle); Callback on errors (check sum, bit disturbance, ) Slide: 12/25

13 CANbedded LIN Integration Init Sequence Example LIN transceiver init (application) LIN stack init LIN communication start Slide: 13/25

17 CANbedded LIN Integration LIN Event Notification Example LIN events are actively reported to the application by using callback functions Slave Application CANbedded LIN LIN DRV SIO DRV LIN Hw Interface UART / LIN Controller Microcontroller 0x3C: SleepCommand LIN Slide: 17/25

18 LIN Diagnostics Node Configuration and Identification Slave nodes are addressed by using a node address for diagnostics NAD Services allow to Read out LIN slave product id and serial number Perform conformance testing Assign new NAD, identifiers (PIDs) > resolve conflicts when reusing existing slaves in new car series Store updated configuration to non-volatile memory LIN Master AssignNAD: newnad = 18 LIN Slave NAD = 12 CAN LIN LIN Slave NAD = 12 LIN Slave NAD = 45 Slide: 18/25

19 LIN Diagnostics UDS UDS Diagnostics Requests can be triggered by DiagTester or LIN master Used for complex LIN slave nodes only (slave diagnostic class II and III) > LIN transport protocol (ISO 15765) with multi frame communication Functional requests and response pending support DiagTester RDBI 0x22 LIN Master RDBI 0x22 LIN Slave NAD = 12 CAN LIN LIN Slave NAD = 8 LIN Slave NAD = 45 Slide: 19/25
