Lin Configuration in Studio 1.4
Clock settings
Lin driver runs on the system clock settings configurable in MCU module.
Recommended settings Clock frequency 8 MHz, IDF = 0, NDIV = 64, ODF=2
LinIf_MainFunction() is expected to be scheduled at a frequency
corresponding to LinTime base (LinIfGlobalConfig. LinIfTimeBase). Make
sure that OsTickFrequency is configured accordingly in Os (Os tick period is
lesser than Time base).
Lin Driver
LinChannelConfigData contains channel specific configuration. Only one channel
per driver is configurable. i.e An ECU can be connected to only one cluster.
LinChannelId can be LIN_CTRL_A to LIN_CTRL_C
Select appropriate clock reference e.g PERIPHERAL_CLOCK_LIN_A
Wake up feature is not supported
Lin Interface
LinIf_Lcfg.c
Frame specific properties using LinIf_FrameType
Checksum type – ENHANCED or CLASSIC
Frame priority not used
Frame type – UNCONDITIONAL for frames triggered by schedule table
Length in bytes
LinIfPid is Frame identifier excluding the parity (Parity calculated by the
driver)
LinIfTxTargetPduId contains the corresponding PDUR_PDU_ID_ABC
Frame SDU not used
Pdu direction can be LinIfTxPdu or LinIfRxPdu
Schedule table entries for each table are created using LinIfEntryType
Specify delay between two start of frames
Entry Index refers to slot in the schedule table
Collision resolve is not used
Frame reference is the index value of the applicable frame
