#define RESET_CAN_CONTROLLER 0x04
These constants can be combined bit by bit so that, depending on the
application, it is possible to reset specific or all CAN components.
Note:
No CAN messages can be sent or received while the CAN interface is
being reset or if the buffer is being erased!
Return Values:
(see Section 7.3.3)
ETHCAN_SUCCESSFUL
ETHCAN_ERR_ILLHANDLE
ETHCAN_ERR_ILLPARAM
ETHCAN_ERR_HWNOINIT
ETHCAN_ERR_HWNOTCONNECTED
Application Example:
tEthCanHandle EthCanHandle;
DWORD dwResetCode;
DWORD dwRetcode;
//Reset all buffers and reset the CAN interface
//of the CAN-Ethernet Gateway
dwResetCode = (RESET_ALL_QUEUES & RESET_CAN_CONTROLLER);
//Reset the CAN interface
dwRetcode = EthCanResetCan(EthCanHandle,dwResetCode);
if(dwRetcode == ETHCAN_SUCCESSFUL)
{
//CAN interface was reset successfully
}
else
{
//An error occurred while resetting the CAN interface
}
