## Detailed Description

Header for a BLF CAN FD message object.

## Member Data Documentation

## ◆ arbitration_bit_count

uint8_t blf_canfdmessage::arbitration_bit_count

Number of bits in the arbitration phase of the frame.

## ◆ canfdflags

uint8_t blf_canfdmessage::canfdflags

Bitmask of BLF_CANFDMESSAGE_CANFDFLAG_* values (EDL, BRS, ESI).

## ◆ channel

uint16_t blf_canfdmessage::channel

Logical CAN channel number on which this message was captured.

## ◆ dlc

uint8_t blf_canfdmessage::dlc

Data Length Code indicating the encoded payload size (0–15 for CAN FD).

## ◆ flags

uint8_t blf_canfdmessage::flags

Bitmask of BLF_CANMESSAGE_FLAG_* values describing message properties.

## ◆ frameLength_in_ns

uint32_t blf_canfdmessage::frameLength_in_ns

Duration of the CAN FD frame on the bus in nanoseconds.

## ◆ id

uint32_t blf_canfdmessage::id

CAN message identifier; bit 31 set indicates a 29-bit extended ID.

## ◆ reservedCanFdMessage1

uint8_t blf_canfdmessage::reservedCanFdMessage1

Reserved; must be zero.

## ◆ reservedCanFdMessage2

uint32_t blf_canfdmessage::reservedCanFdMessage2

Reserved; must be zero.

## ◆ validDataBytes

uint8_t blf_canfdmessage::validDataBytes

Number of valid data bytes in the payload following this header.
