Detailed Description

LIN_RCV_ERROR.

Deprecated

This event may have a wide variety of causes.

An external Master can cause a receive error event:

  • by transmitting sync break that is too short,
  • by not returning the correct value 0x55 in the sync field,
  • by assigning an incorrect parity to the frame identifier. Other reasons:
  • Slave transmitting an illegal character during a Bus Idle phase (e.g. because it did not finish transmission quickly enough and the checksum byte of the response was sent during the Bus Idle phase),
  • Faulty (dominant) stop bit (i.e. framing error),
  • LIN hardware receives a character that is different from the character sent during transmission
  • LIN hardware only receives part of a frame, at the start of a measurement (in a correctly functioning system).

Member Data Documentation

◆ channel

uint16_t Vector::BLF::LinReceiveError::channel {}

application channel

Channel number where the event notified

◆ dlc

uint8_t Vector::BLF::LinReceiveError::dlc {}

LIN DLC.

Frame length

◆ fsmId

uint8_t Vector::BLF::LinReceiveError::fsmId {}

Slave Identifier in the Final State Machine (obsolete)

◆ fsmState

uint8_t Vector::BLF::LinReceiveError::fsmState {}

State Identifier of a Slave in the Final State Machine (obsolete)

◆ fullTime

uint8_t Vector::BLF::LinReceiveError::fullTime {}

Duration of the entire frame [in bit times]

◆ headerTime

uint8_t Vector::BLF::LinReceiveError::headerTime {}

Duration of the frame header [in bit times]

◆ id

uint8_t Vector::BLF::LinReceiveError::id {}

LIN ID.

Frame identifier

◆ offendingByte

uint8_t Vector::BLF::LinReceiveError::offendingByte {}

Byte value that resulted the protocol violation. Only valid for certain values of stateReason

◆ reservedLinReceiveError

uint32_t Vector::BLF::LinReceiveError::reservedLinReceiveError {}

reserved

◆ shortError

uint8_t Vector::BLF::LinReceiveError::shortError {}

Specifies the detail level of the event. Following values are possible:

  • 0: short
  • 1: full Most members are not valid unless this member is 1

◆ stateReason

uint8_t Vector::BLF::LinReceiveError::stateReason {}

The lower 4 bits indicate the LIN hardware state at the time the error has occurred, while the upper 4 bits indicate the reason of the error

Value for the state:

  • 0: Bus idle
  • 1: Waiting for SynchBreak
  • 2: Waiting for SynchField
  • 3: Waiting for frame ID
  • 4-12: Waiting for data byte or checksum byte depending on the frame length. E.g. value 4 for FrameLength=0, value 12 for FrameLength=8
  • 15: Not expected event (i.e. not WakeupRequest) during sleep mode. Occurs for LIN hardware in Master mode only

Values for the reason:

  • 0: Timeout
  • 1: Received an unexpected byte violating protocol. In this case, offendingByte member contains its value
  • 2: Received a byte with framing error (with dominant stop bit). In this case, offendingByte member contains its value
  • 3: Unexpected Break field
  • 4: Unidentified error

◆ timeoutDuringDlcDetection

uint8_t Vector::BLF::LinReceiveError::timeoutDuringDlcDetection {}

Flag indicating if the error is a result of an attempt to resolve frame length. Following values are possible:

  • 0: False
  • 1: True
