#56740 NeonMika.Webserver

Posted by mcinnes01 on 10 March 2014 - 07:12 PM in Project Showcase

Hi 

 

Just wondered if this could work with the MiP library in order to use it on N GO! and standard netduino 1?

 

Also would it be possible to use MQTT with it?

 

Many thanks

 

Andy



#52675 Ethernet Module Update

Posted by mcinnes01 on 09 September 2013 - 09:21 PM in Netduino Go

I often see books on amazon with a similar status? Still if 6 months is a realistic time scale for Go! Bus 1.5 it at least gives us a date to look forward to :)



#58416 Ethernet Module Update

Posted by mcinnes01 on 27 May 2014 - 08:54 AM in Netduino Go

Well that's up to you :) I know its frustrating waiting ages and comms could definitely been handled differently by secret labs, but this is the situation which I'm sure is fairly common when developing new transport protocols especially with netmf ever evolving and having to work around the bugs that are inherited with it.

The suggestion of mip + an enc28j60 is a good cheap alternative or at least stop gap. It is from what I understand the same chip on the ethernet board we are all waiting on. Plus it uses spi, so you only really lose 1 pin for chip select if you use other spi modules and the multi spi library, so not much of a sacrifice. I got it working sharing spi with a gpio expander so I actually gained pins as opposed to lost pins. Also in terms of plug and play, bar a resistor and not having a 10 pin connector or shield format, its not far off. At least this way you can move on with your code and project in the mean time, then when the ethernet module lands, fingers crossed this year, you can simply switch out the mip code for the native network code.

Hth

#58371 Ethernet Module Update

Posted by mcinnes01 on 23 May 2014 - 09:34 PM in Netduino Go

Sigh, why don't you just get a cheap ass ENC28J60 module off ebay for < £3 and use the mIP library?

 

At least this is something that WILL get ethernet to the GO without doubt.

 

Module: http://www.ebay.co.u...=item20d966b102

 

mIP: http://mip.codeplex.com/

 

I'm currently trying to get mIP working with M2Mqtt so I can get GO working with Mqtt, it would be cool to have a few other people helping explore this route :)



#54494 Ethernet Module Update

Posted by mcinnes01 on 05 December 2013 - 07:42 PM in Netduino Go

I have a lot of confidence in the Go! range again, although we haven't seen many gizmo's and do-dads in the last year, in recent months various releases for shield base have come out. Also thanks to Chris for taking the feedback of the community (the good and the less compliment).

 

I think he has done a great job being patient and sympathetic to community frustration, whilst I'm sure secret labs have some of their own, waiting on netmf updates.

 

Whilst I too have been disappointed from time to time, the netduino products are great and other community members must be excited by the imminent prospect of new modules too! Plus QFE1 at the longest will be 3 months at a guess, so I think we have A LOT to be excited for in the not so distant future. :)



#54468 Ethernet Module Update

Posted by mcinnes01 on 04 December 2013 - 07:56 PM in Netduino Go

Hi,

 

Chris is there a planned release date for 4.3QFE1?

 

Are there fixes in this next release of netmf that are holding the next release of Go! Bus up?

 

Many thanks,

 

Andy

 

PS Roll on the new modules :)



#56591 MIP tcp/ip stack running on Netduino mini !!

Ahh that makes sense now, that would be great I would definitely be interested in that :) 



#56629 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 04 March 2014 - 05:53 PM in Project Showcase

I've managed to get all the examples working except the UDP one, do you know what is meant to happen with this one? Does it receive UDP messages and if so how do I test it?

 

My next step is to incorporate MQTT, not sure if anyone has managed this with mIp yet?

 

Many thanks

 

Andy

#57441 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 08 April 2014 - 10:51 PM in Project Showcase

Hi Hanz,

 

Good news, with no amendments to mIp bar the fix in the dhcp.cs and just tweaking your MCP23S17 library to run on the MultiSPI manager, I have been able to get both devices working together.

 

I am still playing with the web server on the netduino in terms of creating input fields and handling the requests as this is my first attempt. If I get something up and running I will post a video.

 

I may see if I can get the neonmika web server running on a standard netduino, any way thanks again for the help.

 

Andy



#58881 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 24 June 2014 - 08:59 PM in Project Showcase

Hi Hanz,

 

Just a quick update, I have confirmation from Paolo who wrote the M2Mqtt library that the network library in his project uses sockets over tcp. There is a TCP class in the mIP library but I wondered if you or anyone else has any ideas or examples of how to implement TCP sockets with mIP. There are great examples of http and UDP but any pointer as to TCP would be greatly appreciated.

 

I guess in regards to my previous post the questions still remain in terms of extending mIP to provide similar structure to System.Net.Sockets in terms of returning int for send, receive and data available?

 

Thanks as ever,

 

Andy



#56589 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 02 March 2014 - 10:13 PM in Project Showcase

Yep already on it on codeplex :)

 

My router is Thomson TG582n

 

I am running my own DHCP and DNS servers in server 2012.

 

TCP/IP is up and running, now just to see if it is possible to get the multi SPI to share with my MCP23S17s... Do you think it is possible?

 

Thanks for all help :)

 

Andy



#57688 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 22 April 2014 - 04:41 PM in Project Showcase

Hi Hanz,

 

I am trying to create an interface between mIP and M2Mqtt, as I understand I need to replace the MqttNetworkChannel with my own implementation that inherits IMqttNetworkChannel and reference my implementation in the MqttClient class. Also I need to replace the dnsLookup in the client class.

 

The IMqttNetworkChannel looks like this:

/// <summary>
    /// Interface for channel under MQTT library
    /// </summary>
    public interface IMqttNetworkChannel
    {
        /// <summary>
        /// Data available on channel
        /// </summary>
        bool DataAvailable { get; }

        /// <summary>
        /// Receive data from the network channel
        /// </summary>
        /// <param name="buffer">Data buffer for receiving data</param>
        /// <returns>Number of bytes received</returns>
        int Receive(byte[] buffer);

        /// <summary>
        /// Send data on the network channel to the broker
        /// </summary>
        /// <param name="buffer">Data buffer to send</param>
        /// <returns>Number of byte sent</returns>
        int Send(byte[] buffer);

        /// <summary>
        /// Close the network channel
        /// </summary>
        void Close();

        /// <summary>
        /// Connect to remote server
        /// </summary>
        void Connect();
    }

Would I be correct in saying that the connect and close methods would come from mIP's Networking class?

 

And Send and Receive from the HttpRequest and HttpResponse classes?

 

I remember reading in the mIP class that it tries to stay away from sockets to make things simpler, would I be right in saying that the mqtt library is using sockets?

 

If so would there be some particular methods I should use instead of the Http ones?

 

Also would you say that Start() in mIP is Connect in M2Mqtt? Stop() relates to Close() ?

 

I have no idea in terms of DataAvailable?

 

Any help would be much appreciated :)

 

Andy



#58871 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 23 June 2014 - 10:09 PM in Project Showcase

Hi Hanz,

 

Just wondered if you could give me a few pointers...

 

I am trying to determine what the equivalent mIP method of the following would be:

public int Send(byte[] buffer)
        {
            return this.socket.Send(buffer, 0, buffer.Length, SocketFlags.None);
        } 

And

        public int Receive(byte[] buffer)
        {
            // read all data needed (until the buffer is full)
            int idx = 0;
            while (idx < buffer.Length)
            {
                idx += this.socket.Receive(buffer, idx, buffer.Length - idx, SocketFlags.None);
            }
            return buffer.Length;
        } 

 this.socket.Send is derived from the System.Net.Sockets method:

public int Send(byte[] buffer, int offset, int size, SocketFlags socketFlags);

and this.socket.Receive is from:

public int Receive(byte[] buffer, int offset, int size, SocketFlags socketFlags);

From what I can tell nothing seems to expose a send or receive method that returns a int, my only conclusion would be that this response is returned until the buffer is empty. I guess this would need some adaptation or extension of the mIP methods?

 

 

And finally the only other method I can't work out the mIP equivalent of is as follows, however it may require some extension if its possible:

public bool DataAvailable
{
   get
   {
      return (this.socket.Available > 0);
   }
}

Again drawing from System.Net.Sockets:

public int Available { get; }
 Your guidance would be greatly appreciated :)
 
Many thanks
 
Andy

#56550 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 01 March 2014 - 04:21 PM in Project Showcase

I am using a standard netduino 1. So am I correct in saying I need to change the method to be as follows:

 

irq = new InterruptPort(irqPin, true, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeLevelLow);

 

And obviously put a 10k between D8 and ground on my N1?

 

Or do I also need to change the interruptmode to EdgeLow as well?]

 

Many thanks

 

Andy



#56545 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 01 March 2014 - 01:34 PM in Project Showcase

Hi Chris,

 

According to the mip library:

 

        [Flags]
        public enum PinValidInterruptMode
        {
            NONE = 0,
            InterruptEdgeLow = 2,
            InterruptEdgeHigh = 4,
            InterruptEdgeBoth = 8,
            InterruptEdgeLevelHigh = 16,
            InterruptEdgeLevelLow = 32,
        }
 
The interrupt is set on EdgeLevelLow, I tried it with EdgeLow and got the same exception?
 
Many thanks
 
Andy

#56533 MIP tcp/ip stack running on Netduino mini !!

Posted by mcinnes01 on 01 March 2014 - 12:19 AM in Project Showcase

Hi,

 

I am looking at the profiles to add my own, but I am a little confused about the pin references...

 

case InterfaceProfile.NetduinoPlus2:
                    // MOSI(PA7), SCK(PA5), MISO(PB4), INT(PA4), CS(PC8) 
                    Start(MacAddress, name, SPI.SPI_module.SPI1, (Cpu.Pin)4, (Cpu.Pin)38);
                    break;
 
I am a little confused not only about the references in the comments, but also over what pin 38 would relate to?
 
So I have my board (which is pretty much the same as yours) connected as follows:
 
Vcc = 3.3v
Gnd = Gnd
Reset = Reset
Sck = D13
MISO = D12
MOSI = D11
CS = D10
Int = D8
 
Hopefully this is correct?
 
Cheers,
 
Andy

Posted by mcinnes01 on 01 March 2014 - 05:24 PM in Project Showcase

I'm pretty sure, the answer is in the error... "Check the interface profile"

 

I think it comes back to my confusion over the values in other profiles of the (Cpu.Pin).

 

I guess that D8 does not equal (Cpu.Pin)8 in reference to a standard netduino 1?

 

Would this be 62 at a guess?

 

And D10 would be 64?

 

Many thanks

 

Andy

Hmm, same issue with google?

 

Erm does that mean my dns server isn't working correctly? I don't seem to have an issue on my laptop? Is there anything I can do to check/resolve this on a network level or could it be an issue with the driver?

 

One interesting thing I noticed was that when I edit the debug info to print out my dns server, it printed out the value of both the primary and secondary in one strange output:

 

Link is now up :)
Setting IP Address to 192.168.1.51

I think that error was an issue with the address odata.netflix.com not returning a dns entry.

 

I managed to get an IP from my DHCP server:

I have the boards connected as follows:

 

(left netduino / right ENC28)

 

Gnd = gnd

3.3v = vcc

Reset = reset

D13 = SCK

D12 = MISO

D11 = MOSI

D10 = CS

D8 = INT (D8 also has a 10K resistor going to ground)

 

The board is from ebay... http://www.ebay.co.u...=item35c89fc698

 

I have added in SecretLabs.NETMF.Hardward.Netduino, so my profile is as follows:

 

case InterfaceProfile.Netduino1:
                    // MOSI(D12), SCK(D13), MISO(D11), INT(D8), CS(D10)

                    break;

My interrupt method is as follows:

irq = new InterruptPort(irqPin, true, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeLevelLow);

I now get the error:

Hi Hanz,

 

When I dig in to the payload that is used to populate the options hash table.

 

I see that for options._buckets[6].value there is an 8 byte array containing the values for both IP addresses.

 

This mean that in this line where bucket 6 is assigned to the ns, there is an invalid ip address being assigned.

 

I updated the packet handler, so I could see what was going on and it seems to now work correctly, so I think this is a bug?
