#10257 Wild idea for a group project

Posted by Jim Davies on 26 February 2011 - 02:57 PM in General Discussion

In an effort to kickstart this and keep it simple, may I suggest we use a channel on ThingSpeak (www.thingspeak.com )?

I heard from ThingSpeak that it will remain free, by the way, so maybe that would help?

#9832 Pachube client for NetduinoPlus

Posted by Jim Davies on 19 February 2011 - 12:10 PM in Project Showcase

Hi Zerov,

Are there any other similar services like Pachube? It's a fantastic idea, but it's a bit to expensive. If I want to monitor my whole house and keep a infinite history, $99 is to much for me.

ThingSpeak looks promising, but I don't see anything about costs yet!
Also, check out sen.se

#7203 Firmware WIsh List

Posted by Jim Davies on 07 January 2011 - 01:18 PM in Netduino Plus 2 (and Netduino Plus 1)

Port scans are not always appreciated in established networks either.

A HTTP HEAD might be better suited btw.

Agreed. I was thinking small network / one-off scan.

#7195 Firmware WIsh List

Posted by Jim Davies on 07 January 2011 - 11:21 AM in Netduino Plus 2 (and Netduino Plus 1)

Ummm... How do you get to the web page?

Sorry - too much Czech lager.

+1 from me for:

Ship it with 192.168.1.50 and allow the user to go to a web page at that address and change it to whatever they want if necessary. Many devices work this way now.

I had the same problem, and found an alternative simple-minded approach that works well for me (ahem):

Scan the local range 192.168.?.? using a short-timeout HTTP GET, and have the server respond with a 200 for some request string, e.g.

http://192.168.?.?/xyzconnect

Get the PC's local IP (e.g. mine's currently 192.168.11.6) and first scan the range 192.168.11.0 - 192.168.11.255. If that doesn't work, scan all the addresses 192.168.?.?.

This works fine here, and quick using the above with a timeout of 100 ms or less.

Of course this approach requires a PC app to do the work, but I think you could also do it in Javascript on the user's browser. Wouldn't this cover most situations with a router or whatever providing local DHCP?

FWIW,
Jim

#7128 Firmware WIsh List

Posted by Jim Davies on 06 January 2011 - 08:44 AM in Netduino Plus 2 (and Netduino Plus 1)

Hi phantomtypist,

You said:

how is the consumer going to find out the IP address of the device if the device's only user interface is a web page it hosts?

Why not just display the device's current IP address on the web page - I guess I'm missing something?

#9168 Help required with Update firmware to 4.1.1

Posted by Jim Davies on 08 February 2011 - 04:03 PM in Netduino Plus 2 (and Netduino Plus 1)

Alan,

when using MFDEploy used to flash chip it still hangs up after finishing with Application executing message so I have to unplu/plug there but beginning to think that is an MFDeploy bug.

I always get this also.

#11070 Recommend a scope or PC card for working with Netduino?

Posted by Jim Davies on 18 March 2011 - 09:43 AM in General Discussion

I also got a Rigol DS1052E oscilloscope - very happy with it.

Or how about a 40kHz 2-Ch DIP-Size Mixed Signal Scope for $49?

#12323 Making the Netduino a little bit closer to a RTOS device

I would love to see this sort of project becoming easier in NetMF, but for anyone who needs to do it 'right now' I have only one word of advice (dare I say it...) - Arduino! Jim

#6894 Suggestions, guidance,help

#6793 Suggestions, guidance,help

Posted by Jim Davies on 01 January 2011 - 06:48 PM in General Discussion

Happy New Netduino Year, Frank! You may find that you need a server on the web site, storing values in a file or database. You would ideally do an HTTP POST to the site with your new value(s), a process running there would store away the value(s), and visitors can then view present and/or past values on web pages setup for that purpose (which retrieve the value(s) from file or database). It's not quite as simple as you were imagining - however there are one or two sites that might make it easier, e.g. www.pachube.com, if you haven't come across it? Best, Jim

#6834 Suggestions, guidance,help

Posted by Jim Davies on 02 January 2011 - 04:08 PM in General Discussion

Hi Frank, I guess you could also implement a web server in your N+ using an HttpListener, and then use an HTML <iframe> on your main web site to show the value(s). Jim

#6657 Ethernet - MFDeploy Ping query

Posted by Jim Davies on 29 December 2010 - 05:38 PM in Netduino Plus 2 (and Netduino Plus 1)

I'm pleased to say I'm having better luck now.

I managed to re-deploy 4.1.0.5 and now MFDeploy and VS2010 are behaving correctly with the board. I'm still not 100% sure what was happening - the main symptoms were:

MFDeploy 'Erase' hanging on 'Rebooting'.
MFDeploy 'Deploy' hanging on 'Executing application'.
VS2010 unable to restart the device when deploying.

Perhaps I'll get back to the Ethernet prob now!

Jim

#6647 Ethernet - MFDeploy Ping query

Posted by Jim Davies on 29 December 2010 - 04:07 PM in Netduino Plus 2 (and Netduino Plus 1)

Ah, thanks CW2 - I get it now. Some of the SAM-BA descriptions don't mention about the USB disappearing and the new COM port popping up!

I haven't erased yet. I'm just trying one more time to deploy NetduinoPlusFirmware_v4.1.1.0_ALPHA_A3 again. It starts OK, with 2 'Signature PASS' - but then hangs on 'Executing application...'. I'm going to leave it for a few minutes and see what happens. (Still there 35 minutes later - killing it now.)

I guess the TinyBooter is OK - should I erase or try something else, I wonder?

I don't have a clear picture of the different layers involved in this.

#6279 Ethernet - MFDeploy Ping query

Posted by Jim Davies on 20 December 2010 - 02:39 PM in Netduino Plus 2 (and Netduino Plus 1)

Thanks Illishar. I'm currently having to plug/unplug the ethernet and plug/unplug the USB in a fairly frequent and usually random fashion! Jim

#6277 Ethernet - MFDeploy Ping query

Posted by Jim Davies on 20 December 2010 - 11:22 AM in Netduino Plus 2 (and Netduino Plus 1)

I'm getting the following:

Often unable to deploy from VS2010 when ethernet is connected to the board.
Often unable to use MFDeploy when ethernet is connected to the board.
DHCP sometimes doesn't work.

Question - I notice that if I have ethernet connected when I connect the board and then run MFDeploy and do a 'Ping', I get:

Pinging... TinyCLR

whereas if the ethernet is not connected, I get:

Pinging... TinyBooter

Is this expected behaviour please? (device capabilities listed below)

#6643 Ethernet - MFDeploy Ping query

Posted by Jim Davies on 29 December 2010 - 02:45 PM in Netduino Plus 2 (and Netduino Plus 1)

Many thanks for your replies, Chris and Illishar. I'm afraid things got worse - nothing to do with Ethernet now. I stupidly tried to install other Alpha/Beta versions of the 'plus' firmware to see if it made a difference (to the Ethernet issues). Unfortunately the netduino plus is now at least half-bricked and I can't even Erase in MFDeploy. It gets as far as 'Rebooting', but then hangs. I've also got a netduino here which is fine on the same machine. And this netduino plus was fine at first. MFDeploy shows the device name OK (I set the 2 boards to different USB names). I've tried keeping the button down while connecting the board (the blue LED stays on) - if I do a Ping or Erase, both hang with no visible output in MFDeploy. I'm looking at the drastic SAM-BA option, but neither SAM-BA 2.1 nor SAM-BA v2.10_cdc offer USB on the initial connection dropdown - only 'com2', 'com3' and 'com4'. I have an old album called 'Unhalfbricking' by the group Fairport Convention - maybe I can do something with that? Help please. Jim

#8460 Help a wife buy a present

Posted by Jim Davies on 26 January 2011 - 12:43 PM in Netduino 2 (and Netduino 1)

Thank you
I've put in an order for the netduino, a voice shield (the other one was out of stock) and some other stuff now.

I think my husband and I are good at getting each other gifts (hence the netduino ha ha), I know he really wants one.
If you're in trouble you can never go wrong with chocolate, right?

Did you order a Netduino Plus?

Anyway, if you can't get the Netduino you want, consider a decent single malt (Scotch whisky). It helps after the programming...
