Samjones et al, did you manage to solve your OutOfMemory issue?
Miha,
No, sorry. I gave up on SD writes because it was not critical to my project.
Sorry!

#29013 ETA for 4.2 ? .. seems kinda quiet...

I don't think it's quiet around 4.2; just 4 days ago a brand new firmware is posted:
http://forums.netdui...-netduino-plus/
You're right. What I did was come to the forum, and not see any top of the list threads related to 4.2.... so it "sounded" quiet to me.

#28371 Does ngo have unique serial no that can be read from code?

Perhaps we could create a class/method which exposes this? Or expose it via one of the built-in NETMF classes?
Please make it easy to see via NETMF, and make it portable across netduino +, GO, etc.
This would rock!

I was looking for this kind of identifying feature on the Plus.
On the plus I use the enet MAC... works great!

I think that being able to uniquely identify any Netduino chip would be a common need for a few people - how about a generic static property across all Chips?
Yes!

And here I thought I was the oldest poker on this board.... I was bootstrapping Imsai 8080 ( http://en.wikipedia....wiki/IMSAI_8080 ) as a ten year old from the front panel, and loading the BASIC interpreter Bill Gates wrote from paper tape.
Fantastic bunch of fogeys around here!
#27956 Ethernet never works if not connected on boot up?

Kluger's work explains why I've had no trouble: my code starts the router and then idles. It is the network availability event that causes my code to attempt to connect a socket. And therein, I suppose, lies a reasonable workaround: don't try to use the network until it is ready.
Arbiter,
I almost follow you.... but not quite!
How do you test:
a) For physical connection (e.g. that enet port is plugged into a powered up hub)
and
For ip connectivity to the netCode samples very welcome!
Thanks!

The whole point to purchasing/using the Netduino+ was for it's ethernet port. If that is not rock solid and robust (or at the very least reliably recoverable) it makes it pretty much a 'toy' and difficult/impossible to use for any serious application.

The ND+ has a great stealth feature: The MAC is like a unique board identifier, and I can read it in code....
Does NGo allow me to read the cpu SN or such from code?

OK, so my netduino's miss me?
I have been working on the electronics side, and have just returned to the netduino side code. Annd, VS won;t talk to netduino!
mfdeploy connects fine.
Using all the released 4.1 stuff
On a machine I have used for this work from the start
Tried with three different netduino boards.
Given that the problem spans boards, reflashing boards seems wrong (for multiple reasons).
Soooo, it must be on my machine?
- reinstalled netduino 4.1 sdk from http://netduino.com/downloads/
- rebooted (couple of times)
- rebooted the netduino board
- checked that mfdeploy is happy
--- Yes, I always exit mfdeploy prior to starting VS
Now what?
(The only suggestion I have seen is to copy into a new project, but that is both a hassle and unneeded, as this is a working project under version control.)
Thanks!
#25684 How much current can I draw from micro USB ?

Netduino Plus 2 (and Netduino Plus 1)
I am working out how to power a few devices and have a question...
If I power netduino w/ 800ma 5v source on the 5v header, and I have a usb device that needs power:
- a ) Will the micro-usb socket on the netduino provide 5v?
- b ) How much can I draw on the micro-usb?
Thought I would ask first,,, before cooking something!
Thanks!

Chris,
Thank you, will work in that direction!
Question: The netduino is speced at a 7.5v min input. If I use a 5v or 6v regulated psu, can I put that into the barrel connector?

Chris,
I understand the 200mA limit on the io pins.
It sounds like on the 5v header pin, I could do 200-350mA ? (e.g. to power a small wifi bridge) ?
As I understand it, the netduino plus board itself max draw is 200mA. So is the following warm?
9v, 600mA PSU to netduino input
350mA load on 5v header pin
Couple small devices hanging off of other pins, drawing 50-150mA total
Warm?

I am looking at:
http://www.netduino....oplus/specs.htm
and don't see the answer to this question:
How much power can I draw from the on 5v header?
(I guess the same goes for how much can I draw from the 3.3v header?)
I see the specs say "microcontroller max current: 200 mA total"
Does that mean the whole netduino plus board will never draw more than 200 mA ?
Thanks!

I second the motion by Arbiter, and would also participate in a kickstarter initiative, but I would add to the list for the documentation:
5. Demonstration http server (serve a single "hello world" html that can be in code)
6. Demonstration http client that does a GET from a weather or other simple url that returns a dynamic value and outputs this to debug.print

Sure thing. I will have more info regarding watchdog for you in a few weeks... Stay tuned.
That is the best news I have heard this week!
Thank you!

Chris,
Thanks for the perspective. We will look at all of the above, of course, before taking action.
The netduino plus board (what we use) plus all the other gizmos (wifi bridge for $35, case, psu, other parts, cables) adds up to higher than ideal for our whole device. So I am researching options.
Side note: Can we contact you directly RE watchdog in 4.2?

Chris,
Thanks.
Waah! (Was hoping to get a better discount direct.)
I guess the question is: If we need (N x 10^2) or more boards, do we end up netting out building our own board? (When we would rather purchase at cost + % from secret labs and avoid the engineering effort.)
