Field Documentation

@1

union { ... }

bitrate

unsigned short bitrate

Bitrate of the message in bits per second. Range [1000 .. 60000] (plus some margin)

checkSum

unsigned char checkSum

Checksum as read from the J1587 bus. Might not match the data in case of J1587_CSUM_ERROR.

flags

unsigned char flags

Miscellaneous flags

frameDelay

unsigned char frameDelay

Frame delay in bit times (up to 255).

• Read: Length of inter-frame delay.
• Write: Delay before message transmission could begin.

frameLength

unsigned long frameLength

Total frame length in microseconds; from the first start bit to the end of the checksum.

reserved

unsigned short reserved

Reserved

retries

unsigned char retries

Number of retries before message could be transmitted.

timestamp

unsigned long timestamp

Timestamp in ms of the reception/transmission completion of the checksum. Uses the canlib CAN timer.

version

unsigned char version

To enable future extensions of this structure (see J1587LIB_VERSION).
