the returned address must not be NULL. The structure elements are to
be initialized with 0.
Return Value:
(see Section 7.3.3 and 7.3.4)
ETHCAN_SUCCESSFUL
ETHCAN_ERR_ILLPARAM
ETHCAN_ERR_ILLHANDLE
ETHCAN_ERR_HWNOINIT
ETHCAN_ERR_HWNOTCONNECTED
ETHCAN_CANERR_QXMTFULL
Application Example:
tEthCanHandle EthCanHandle;
tCANMsg CanMsg;
tCANTimestamp SendTime;
DWORD dwRetcode;
//Initialization of a Standard-RTR-Frame
CanMsg.m_dwId = 0x180; //CAN-ID
CanMsg.m_bMsgType = ETHCAN_MSGTYPE_STANDARD & ETHCAN_MSGTYPE_RTR;
CanMsg.m_bLen = 8;//8 Byte requested Data length
SendTime.m_dwMillis = 0;
//Send CAN-message
dwRetcode = EthCanWriteCanMsg(EthCanHandle,&CanMsg,&SendTime);
if(dwRetcode == ETHCAN_SUCCESSFUL)
{
//CAN-message sent
}
else
if(dwRetcode & ETHCAN_CANERR_ QXMTFULL)
{
//Overflow of the send buffer
}
else
{
//Error when sending the CAN-message
}
