All,

Can someone provide the steps needed to restore an Netduino that has been erased? Believe it or not.. I managed to accidentally erase my Netduino during testing...

Jason.

            NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();

            {  
                networkInterface.EnableDhcp();
            }

In theory, yes. But some PCs have auto-detect and will swap the RX/TX if you use teh "wrong" cable.

Are you running on a Windows PC with an Ethernet jack? You could set up network connection sharing and plug the Netduino into your PC...

new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp))

SendTo instead of Send

Bind instead of Listen

ReceiveFrom instead of Receive

    {

        public static void Main()
        {
            // write your code here
            NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();

            foreach (NetworkInterface networkInterface in networkInterfaces)
            {
                Debug.Print("IP Address: " + networkInterface.IPAddress);
                Debug.Print("Subnet mask " + networkInterface.SubnetMask);

        }

    }
}

The signals to the servos are just pulses which direct the servo's position. It's the power from the 5V/3.3V header which is providing the power.

The Netduino can provide 100s of mA of power. The on-board power regulators are rated at 800mA. You can draw a few 100 mA of power for your projects...not a problem. Just remember to use an external power supply (via the power barell or VIN connector) if you're drawing a bunch of current.
