From Netduino to PC's USB-to-Serial

Serial COM

Ok, got it working.

 

Now I know that my USB-to-Serial works! It was really as simple as I thought :).

 

private static SerialPort _serial = null;

 public static void Main()
        {
            using(_serial = new SerialPort(SerialPorts.COM1, 9600, Parity.None, 8, StopBits.One))
            {

                _serial.Open();

                for(int i = 65; i < 85; i++)
                {
                    _serial.Write(new[] { (byte)i }, 0, 1);
                    Thread.Sleep(1000);
                }

                _serial.Close();
            }
        }

Hello.

I have a USB-to-Serial adapter and would like to test it. So, I would like to send a basic command from Netduino to PC and be able to read it.

 

Attached File  USB-To-SERIAL.jpg   19.89KB   2 downloads

 

so, Putty will be listening on the PC's side and Netduino will be sending a signal.

 

should it be wired like that?

 

Digital 0  > TXT

Digital 1 > RXD

 

(The adapter is connected to USB, so I think it's getting its power from USB)

 

Then from the code, use a SerialPort with COM1 and then send a signal?

 

Does this sound right?

 

Thanks!
