union {
uint32_t   std_id: 11
uint32_t   ext_id: 29
};
uint8_t	ext_addr

Detailed Description

ISO-TP message id struct.

Used to pass addresses to the bind and send functions.

Field Documentation

union { ... } isotp_msg_id::@90

CAN identifier

If ISO-TP fixed addressing is used, isotp_bind ignores SA and priority sections and modifies TA section in flow control frames.

ext_addr

uint8_t isotp_msg_id::ext_addr

ISO-TP extended address (if used)

ext_id

uint32_t isotp_msg_id::ext_id

id_type

uint8_t isotp_msg_id::id_type

Indicates the CAN identifier type (standard or extended)

std_id

uint32_t isotp_msg_id::std_id

use_ext_addr

uint8_t isotp_msg_id::use_ext_addr

Indicates if ISO-TP extended addressing is used

use_fixed_addr

uint8_t isotp_msg_id::use_fixed_addr

Indicates if ISO-TP fixed addressing (acc. to SAE J1939) is used
