Member Enumeration Documentation

eBusStatus

enum eBusStatus

CAN 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.

Definition at line 208 of file can_types.h.

eDataFlags

enum eDataFlags

CAN 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.

Definition at line 197 of file can_types.h.

eMessageTag

enum eMessageTag

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

Enumerator
MT_Data	Data.
MT_Status	Status.

Definition at line 188 of file can_types.h.

eMsgId

enum eMsgId

CAN 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 messages are marked by bit 31.
