Detailed Description

CAN message structure.

Used to pass can messages from userspace to the driver and from driver to userspace

Field Documentation

union { ... } zcan_frame::@105

The frame payload data.

brs

uint8_t zcan_frame::brs

Baud Rate Switch. Frame transfer with different timing during the data phase. Only valid for CAN-FD

data

uint8_t zcan_frame::data[8]

data_32

uint32_t zcan_frame::data_32[ceiling_fraction(8, sizeof(uint32_t))]

dlc

uint8_t zcan_frame::dlc

The length of the message (max. 8) in byte

fd

uint32_t zcan_frame::fd

Frame is in the CAN-FD frame format

id

uint32_t zcan_frame::id

Message identifier

id_type

uint32_t zcan_frame::id_type

Indicates the identifier type (standard or extended) use can_ide enum for assignment

res

uint8_t zcan_frame::res

Reserved for future flags

rtr

uint32_t zcan_frame::rtr

Set the message to a transmission request instead of data frame use can_rtr enum for assignment
