ncwrite

[r78]

 use PCI-CAN Series2 transmit CAN Frame:

My  configure is following:

NCTYPE_STATUS CTransmitView::Write(NCTYPE_OBJH ObjHandle, NCTYPE_UINT32 DataSize, NCTYPE_ANY_P DataPtr)
 {   Transmit.IsRemote = 0;
 Transmit.ArbitrationId = 0x04; 
 Transmit.DataLength = 8;
 Transmit.Data[0] = 0x55;
 Transmit.Data[1] = 0x55;
 Transmit.Data[2] = 0x55;
 Transmit.Data[3] = 0x55;
 Transmit.Data[4] = 0x55;
 Transmit.Data[5] = 0x55;
 Transmit.Data[6] = 0x55;
 Transmit.Data[7] = 0x55;
 
  Status= ncWrite(TxHandle, sizeof(Transmit), &Transmit);   
    if (Status < 0)
    {
    PrintStat(Status, "ncWrite");
    } 

}

Use Button to transmit:

Transmit Program-> Write(TxHandle,sizeof(Transmit),&Transmit);

Why? only display ID and Data?

I need to traansmit complete frame include start of bit...Data....DataLength.....ID.....?

Hi,

The write net allows you to change ID, DataBytes, DataLength and the Remote Flag. That's it. Everything else is automatically handled by the driver.

I has been know. Thanks

But according my describe, only transmit out ID and DataLength.

why not have Data?

Use Write(TxHandle,sizeof(Transmit),&Transmit) to output.

The program code  of  Write(TxHandle,sizeof(Transmit),&Transmit) is error or ncConfig isn't configure complete?
