Member Enumeration Documentation

CAN FD bus state flags.

Enumerator
BS_OFFLINE	Bus is offline.
BS_ERROR_PASSIVE	One of the error counters has reached the error level.
BS_ERROR_WARNING	One of the error counters has reached the warning level.
BS_ERROR_ACTIVE	Bus is online.

CAN FD message flags.

Enumerator
DF_NONE	Standard flags.
DF_ERROR_FRAME	Indicates an error frame.
DF_REMOTE_FRAME	Indicates a remote frame.
DF_TX_COMPLETED	Notification for successful message transmission.
DF_EXTENDED_DATA_LENGTH	Indicates FlexibleData-Rate (FDF Flexible Datarate Format Indicator)
DF_CAN_FD_FORMAT_IDENTIFIER	same as Extended Data Length
DF_BAUD_RATE_SWITCH	Indicates that the Message uses Flexible Datarate.
DF_SET_CAN_FD_AND_BRS	Helper to Set Extended Data Length and Baud Rate Switch at once.
DF_ERROR_STATE_INDICATOR	EDI Bit Indicates an Error-active state at the CAN FD Node

This enum specifies the different kinds of messages that may be contained in the union.

Enumerator
MT_Data	Data.
MT_Status	Status.

CAN FD message id masks.

These masks should be used to check for extended or standard messages and to get the correct identifier from ui32Id in tData.

Enumerator
MSG_IDMASK_BASE	Message IDs for base frame format use 11 bit identifiers.
MSG_IDMASK_EXTENDED	Message IDs for extended frame format use 29 bit identifiers.
MSG_EXTENDED_FLAG	Extended CAN FD messages are marked by bit 31.
