How to use the new functionalities

Hi,

I've got my Netduino Plus in today.
And i'm wondering how to use the new functionality... I guess I must include some new assemblies? if so where can I find them?

Can I use this? Beta assmblies for SD card

And this one? Beta assmblies for ethernet

Thanks

SD card: System.IO.dll Network: System.dll (for sockets) Microsoft.SPOT.Net.dll (if you want to change your IP settings from code) To change your static IP (or to test out the "unsupported" DHCP): Run MFDeploy. Target menu > Configuration > Network We haven't even made the announcement yet, and community members are already building stuff Fantastic! Chris Edit: There's also the System.Http assembly...which gives you the ability to download and parse web pages with ease. It _might_ be too big if you're running a sophisticated program--but it might not be. Feel free to play with it, and maybe we can free up some additional flash for code as well...

Aha.. cool.

For those interresed, here's how to list your network properties:

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using Microsoft.SPOT.Net.NetworkInformation;

namespace NetduinoApplication2
{
    public class Program
    {

        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);
            }


        }

    }
}

Seems like my netduino plus is hardcoded to IP static IP address 192.168.5.150/24

Here's how to send data:

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using Microsoft.SPOT.Net.NetworkInformation;
using Microsoft.SPOT.Net;
using System.Net.Sockets;
using System.Net;
using System.Text;

namespace NetduinoApplication2
{
    public class Program
    {

        public static void Main()
        {

            using (System.Net.Sockets.Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
            {

                IPHostEntry entry = Dns.GetHostEntry("192.168.5.111");
                IPAddress address = entry.AddressList[0];
                IPEndPoint endpoint = new IPEndPoint(address, 80);

                socket.Connect(endpoint);
                socket.Send(Encoding.UTF8.GetBytes("Hallo Netduino plus"));
            }

        }

    }
}

It is very cool. I can't wait to get home and plug mine in. Though I don't have a route to a 192.168.x.x network from my home 172.16.15.x subnet, so I'm not sure if I can get it to change the ip or not. Hopefully I can.

Sure you can.. I guess this would be the easiest:

            NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();  
  
            foreach (NetworkInterface networkInterface in networkInterfaces)  
            {  
                networkInterface.EnableDhcp();
            }

When I said hardcoded.. I really meant 'defaulted to'..

Steven, Sorry, forgot that part! I just updated my original post in the thread... To change your static IP (or to test out the "unsupported" DHCP): Run MFDeploy. Target menu > Configuration > Network Chris

Oh.. won't EnableDhcp() work ?

Ah, very cool. Thanks for that! I've got a 1 gig microSD card all ready to go as well. Hopefully it will work with SPI.

DHCP is built in...but we're asking users to use static IP for their first projects to make sure we get any kinks worked out with the networking before we start introducing any other variables to the equation

Chris

To make it complete.. here is how to receive data

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using Microsoft.SPOT.Net.NetworkInformation;
using Microsoft.SPOT.Net;
using System.Net.Sockets;
using System.Net;
using System.Text;

namespace NetduinoApplication2
{
    public class Program
    {

        public static void Main()
        {

            using (System.Net.Sockets.Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
            {

                socket.Bind(new IPEndPoint(IPAddress.Any, 80));
                socket.Listen(1);

                using (Socket commSocket = socket.Accept())
                {
                    if (commSocket.Poll(-1,SelectMode.SelectRead))
                    {
                        byte[] bytes = new byte[commSocket.Available];
                        int count = commSocket.Receive(bytes);

                        Debug.Print(new String(Encoding.UTF8.GetChars(bytes)));
                    }
                }                
            }
        }
    }
}

Have fun !!!

Btw.. I haven't tested the code above yet.. I'll have to get a switch to connect the netduino.. i'm on wireless only atm

And for UDP, use:

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

And in the client:

SendTo instead of Send

In the server:

Bind instead of Listen

and

ReceiveFrom instead of Receive

Btw.. I haven't tested the code above yet.. I'll have to get a switch to connect the netduino.. i'm on wireless only atm

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...

Chris

Good idea... won't I be needing a cross cable for that?

Is there a way to put a .Net assembly on the SD card, load it and then run it from the Micro .Net Framework? Maybe some sort of primitive task switcher could be made.

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

Why yes, yes there is. You can use AppDomains and load assemblies on the fly

You do have dozens of KB of memory (not MBs)--so keep that in mind.

Yeah... my router will do that too... rather handy.

Ha.. connected a cable to my notebook and all the lights come on.. I guess it's working.
Will be testing more tomorrow.. bedtime now.
