I just published a new version of the mIP library with a lot of changes. Some of the Highlights are:
[ul]
Completely New Driver written from the original Microchip source, so there are no more GPL restrictions (that was hard)
Cable connect disconenct works great with automatic DHCP address update
Fixed DHCP negotiation for several routers (including D-Link and Netgear)
Added device name to DHCP message so it now shows up in router configuration menus!
Made extenstion methods compatible with .NET MF 4.1
Used a Debug.Print command that actually is not compiled in Release mode (reduces memory required)
Fixed a huge memory leak (worked for 24 hours straight today having never failed!)
Added some automatic recovery code (it works, but it could be better. Automatically restarts enc28j60)
Made Netbios over TCP enabled by default (for WinXP compatibility)
Removed Reset pin because it was clear from the spec sheet that it is never necessary when using SPI
And moreā¦[/ul]
Jay Jay, howās that stab at uPNP coming? If you are making progress let me know. Otherwise, I might look at it myself soon.
Hi,
Please find below the Desktop version of the Port Forwardingā¦ it was easier to get started with the desktop version to make sure it works now Iāll have to convert it to NetMFā¦ iāll try to get to it over the weekend.
Edit: removed the Desktop Version of the code to not cause confusion for other user and new netMF code will be released on Codeshare soon....
Whatās missing in the above is the Presentation Web Page Iconā¦ the one that popups in windows when it detects UPnp and when you click on it, it takes to a local page ā¦
Cheers,
I tried to get it up and running today on a modified Discovery board, but it doesnāt work yet. --> works now!
Wiring: Reset --> PB10, CS --> PA13, SCK --> PB3, MISO --> PB4, MOSI --> PB5, INT --> PA14, WOL --> PB11
I removed the SB12 connection from the back of the Discovery board. It connected the PB3 pin to the ST link part of the board and removed the ST-LINK jumpersā¦
Now the hardware parts worksā¦
No Iām stuck at the following, the code keeps resetting the ENC28:
A first chance exception of type 'System.NotSupportedException' occurred in Microsoft.SPOT.IO.dll
The thread '<No Name>' (0x2) has exited with code 0 (0x0).
Executing a Complete RESET at 06/01/2011 00:09:29
The thread '<No Name>' (0x3) has exited with code 0 (0x0).

Very interesting. It looks like you are using the second release, v0.2. In the first release, it had a bad memory leak and I debated a few things with myself. Should I cap the number of connections and buffer, dropping packets when I hit the limit, or should I let the amount of memory you have on your device be your limit. I kind of settled on a hybrid for now. I capped the connections, added a connection timeout, but also decided to do a RESET if I started to run low on memory. This free memory minimum may be too high for some devices though, itās hard-coded to 10k or 15k (canāt remember exactly). The reason it is so large is because I wanted to trigger the reset before I get an OutOfMemory Exception and 15k was a good number when the web server was getting hammered. Anyway, my first guess it you are hitting the memory minimum. Since itās managed, you can put a break point on the line that prints āExecuting a Complete RESETā and look at the if/then statement to see what condition caused it. Yay for Managed code! Also, you could put some statements in the code to see how much RAM you have, like this: Debug.WriteLine("Free Mem = " + Debug.GC(false));
Also, I have one of these discovery boards, but never used it. Maybe Iāll load up the firmware and try to reproduce this.
Also, WOL I donāt believe is implemented (although I think itās just an option in the enc28j60). And, RESET should not be necessary.
Also, while the first version of mIP (v0.1) only ran for 15 minutes, the current version (v0.2) has run for 2 days, serving the sample page every 5 minutes.
Update: I just noticed there are 2 link up events! āLink is now up : )ā That is suspicious. Like I mentioned above, put a breakpoint on the reset method and see what led to the reset. Also, you can just comment out the call to the reset() method. It is probably not actually necessaryā¦

Seems the received bytes is āway offāā¦
And when I run the version 0.1 it says: Verify that you have selected the correct InterfaceProfile in the Networking.Adapter.Start method
After removing the U9 chip from the board (using a cutter :S) that message dissapearsā¦ but still no connection possible (but also no debug messages)
Grmblā¦ seems I need to lay my hands on an ENC28 module and a cerberus board in order to determine where the problem residesā¦ I could try switching the ethernet moduleā¦
There is something wrong with the interrupt on your enc28j60. Your output keeps showing āLink is now up :)ā. Thatās a big clue because it should only invoke that event for when the link has changed, but it is up every timeā¦ So it appears that the link has not changed, but according to the PHIR_PLNKIF register bit, it has changedā¦ First, try a different port on your router and a different cable (probably wonāt help).
Your enc28j60 controller could be a different rev and there are differences in the revsā¦ There is a line commented out in the driver to get the RevID. Use that to get the Rev and Iāll check mine to see if there is a difference thereā¦ And, if there is, we can look at the errata for the revs to see if there is an issue with that register.
This is the code from the driverā¦
// 12.1.5 -- Performing an MII read on the PHIR register will clear the LINKIF, PGIF and PLNKIF bits automatically
var physicalInterruptRegister = ReadPhyReg(PHIR);
bool linkChange = (physicalInterruptRegister & PHIR_PLNKIF) != 0;
// now we can fire events
if (linkChange && OnLinkChangedEvent != null) OnLinkChangedEvent.Invoke(this, time, IsLinkUp);
Alternatively, I could try to setup what you have there or you could ship yours to meā¦
I have the exact same setup here: discovery board + chinese ENC28J60 module, but mine does work:
Link is now up
Setting IP Address to 192.168.2.4
DHCP SUCCESS! We have an IP Address! 192.168.2.4
Gateway: 192.168.2.1
Updating Gateway Mac from ARP
Local Name Request (LLMNR, Type A) for discovery
LLMNR Response sent
How did you do the wiring? And how can you check the revision? I bought 3 of em, so Iāll replace the one Iām currently using to see if itās broken.
@ Valkyrie-MT
It serves up the default webpage when i navigate to the device hostname (in my case http://discovery)
My router is a US Robotics USR5464 Wireless NDX router.
@ iwritecode
My wiring is done exactly like yours, which is as per the Cerb40_ENC28J60 InterfaceProfile.
Iāve also removed the SB12 solderbridge, but i left all ICās ob the board.
You can uncomment and modify the code to print de revision register byte in void Restart():
ENCRevID = ReadEthReg(EREVID);
Debug.WriteLine("ENC28J60 Revision " + ENCRevID.ToString());
(Remember to also uncomment the declaration: private byte ENCRevID = 0x00;)
I finally had the time to work on Upnp and i successfully opened a port on my Routerās firewall from my spiderā¦ and started a web server listening on that portā¦ Yaaaaaaaaaaaayyyy
i will be cleaning up the code and add the other required functionsā¦ like deletePort and Discover the External IP and so onā¦
Edit: now i can delete the port as wellā¦ cool
next to do is Discover the external IP of the Routerā¦
Fantastic! I also have more improvements after serving up pages from an SD card. Iāll be integrating those within the next week, but they should not conflict with this. Super!
thank you Valkyrie-MT,
and iām making good progress hereā¦
So far i have the following working:
Discover if UPnP is enabled.
Open Firewall ports
remove the opened port.
Get the external IP Address.
To Do:
Listen to Broadcast and show the device as a Home Automation Device for example with a Presentation Web Page. (So far i can listen to Broadcasts successfully) now i just need to filter the data and reply back with the proper Soap xmlā¦more research and readingsā¦
return a Proper Soap Error when we get invalid data from other UPnP devices.
QueryStateVariable
GetStatusInfo
GetConnectionTypeInfo
GetNATRSIPStatus
GetGenericPortMappingEntry
GetSpecificPortMappingEntry
AddAnyPortMapping
DeletePortMappingRange
GetListOfPortMappings
and moreā¦
now i do have questions for those who are going to be interested in this:
how do you think this library should constructed, should be made a class or an interface? since it will require info from the end user to configure the deviceā¦like device friendly name, presentation url and so onā¦quite a bit of info actually.
I would lean toward a class. But, construct it such that a small change can disable the feature (in case someone needs the memoryā¦ letās take advantage of having a managed stack!)
For Device Friendly name, can you use the Name Property of the Network.Adapter class? Maybe that is the default value?
Can Presentation URL just be contructed from the network adapter name? like http://adapterName
Those 4 features you have there will be fantastic!
Everything the class will required is going to be in the form of a string (Property), so you can make it anything you want.
so for question 1: yesā¦
and question 2: yes
Hi Gralin,
i most certainly willā¦
i just need to get the stuff working and once i have all of the above implemented i will post what i haveā¦
So far i think the Class will be a singleton class since you can only have one single Control Point device started per deviceā¦ this will avoid user starting multiple control points per deviceā¦
most required info will be added as fields i think instead of Propertiesā¦ man i miss Custom Attributes i wish NetMF would include those in the futureā¦ still not sure which way to go yetā¦
