dwTxMsg-
InfoIndex IN UCI_FLXMSGTYPE_DATA:
If you want to send a FlexRay message and you use a mes-
sage prototype retrieved from GetTxMsgInfo() you can speci-
fy the dwTxMsgInfoIndex to use. If you enter
UCI_FLX_TX_MSG_INFO_INDEX_DONT_ CARE the functions
tries to find the appropriate message buffer on its own using
only the Buffers without configured cycle counter filter.
The configuration of the FlexRay Identifier leads to a reconfi-
guration of the message buffer on the FlexRay hardware,
which causes a longer processing time.
UCI_FLXMSGTYPE_CONTROL:
If you want to send a control message it depends on the
type of control message, whether the dwTxMsgInfoIndex has
to be specified. For following control message dwTxMsgIn-
foIndex has to be given:
•
UCI_FLXCTRLMSGTYPE_TXBUFFER
The configuration of the buffer can be read with
GetTxMsgInfo() .
Return value: UCI error codes
