Member Data Documentation

appParameter

uint32_t blf_flexrayrcvmessageex::appParameter

Application-specific parameter associated with this message.

blfLogMask

uint16_t blf_flexrayrcvmessageex::blfLogMask

Bitmask controlling which elements of this frame are logged.

channel

uint16_t blf_flexrayrcvmessageex::channel

Logical FlexRay channel number on which this frame was captured.

channelMask

uint16_t blf_flexrayrcvmessageex::channelMask

Physical channel mask: 0 = reserved, 1 = channel A, 2 = channel B, 3 = A+B.

clientIndex

uint32_t blf_flexrayrcvmessageex::clientIndex

Index identifying the client that recorded this message.

clusterNo

uint32_t blf_flexrayrcvmessageex::clusterNo

FlexRay cluster number from which this frame originated.

cycle

uint16_t blf_flexrayrcvmessageex::cycle

FlexRay communication cycle counter at the time of capture.

data

uint32_t blf_flexrayrcvmessageex::data

Application-defined data word associated with this message.

dir

uint16_t blf_flexrayrcvmessageex::dir

Transfer direction: 0 = RX, 1 = TX, 2 = TX Request, 3 = internal, 4 = internal.

frameCRC

uint32_t blf_flexrayrcvmessageex::frameCRC

CRC value of the complete FlexRay frame as transmitted on the bus.

frameFlags

uint32_t blf_flexrayrcvmessageex::frameFlags

Bitmask of FlexRay frame flags (e.g. startup, sync, null frame, payload preamble).

frameId

uint16_t blf_flexrayrcvmessageex::frameId

FlexRay frame identifier (slot ID) of this frame.

frameId1

uint16_t blf_flexrayrcvmessageex::frameId1

Secondary frame identifier used for additional frame correlation.

frameLengthInNs

uint32_t blf_flexrayrcvmessageex::frameLengthInNs

Total duration of the FlexRay frame on the bus in nanoseconds.

headerCrc1

uint16_t blf_flexrayrcvmessageex::headerCrc1

Header CRC computed for channel A.

headerCrc2

uint16_t blf_flexrayrcvmessageex::headerCrc2

Header CRC computed for channel B.

payloadLength

uint16_t blf_flexrayrcvmessageex::payloadLength

Nominal payload length in 16-bit words as defined by the static segment configuration.

payloadLengthValid

uint16_t blf_flexrayrcvmessageex::payloadLengthValid

Number of payload bytes actually captured and valid in the payload buffer.

pduOffset

uint16_t blf_flexrayrcvmessageex::pduOffset

Byte offset to the start of the PDU within the frame payload.

res1

uint16_t blf_flexrayrcvmessageex::res1

Reserved; must be zero.
