CAN – Ethernet Gateway

Application Example:
#define IP_ADDR_DEFAULT ((192 << 0)+(168 << 8)+ (10 << 16)+(111 << 24))
#define IP_PORT_DEFAULT (8234)
DWORD dwRetcode;
tEthCanHandle EthCanHandle;
tEthCanHwParam EthCanHwParam;
EthCanHwParam.m_dwReconnectTimeout = 120000;//120s
EthCanHwParam.m_dwIpAddress = IP_ADDR_DEFAULT;
EthCanHwParam.m_wPort = IP_PORT_DEFAULT;
EthCanHwParam.m_dwConnectTimeout = 5000;//5s
EthCanHwParam.m_dwDisConnectTimeout = 5000;//5s
without Callback Function:
// initialize a CAN-Ethernet Gateway without a Callback function
dwRetcode = EthCanInitHardware (&EthCanHandle,&EthCanHwParam,NULL,NULL);
with Callback Function:
void PUBLIC EthCanConnectControlFct (tEthCanHandle EthCanHandle_p,
DWORD dwConnectionState_p,
void* pArg_p)
{
switch(dwConnectionState_p)
{
//Connection in process
case kConnecting:………………………
break;
//Connection Established
case kEstablished:……………………
break;
//Disconnecting
case kClosing:………………………………
break;
//Disconnected
case kClosed:…………………………………
break;
}
}
//initializes a CAN-Ethernet Gateway with Callback function
dwRetcode = EthCanInitHardware (&EthCanHandle, &EthCanHwParam,
EthCanConnectControlFct,NULL);
