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).

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

reserved
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
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
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
