Will anyone else be at ESC Boston (Sept. 26-29) http://esc.eetimes.com/boston/?

Interested in meeting up?

Here is a nice presentation Powering your embedded devices with C# and .NET Micro Framework in which Netduinos are featured.

Anyone planning on attending the session Having fun with Netduino by Carl Bergenhem and Chris Gilmore this Saturday (29-OCT-2011) at the New England Code Camp in Waltham, Mass (USA)?

More info at: http://codecampboston.eventbrite.com/

Pete Brown did an excellent presentation with lots of Netduino (and Netduino GO) goodness at South Florida code camp.
Gadgeteering and the .NET Micro Framework

I was surprised to see that at least one supplier has started discounting Netduinos and apparently has both Netduinos and Pluses in stock.

Tech Junkies just posted Open Source Robot Controls which uses a Netduino Plus. It is totally open source (hardware and software). The video is excellent and includes a walk-through of the Netduino code.

Microsoft is looking for hardware vendors who are interested in developing kits and modules, so you could contact them if you are interested.

Curious if anyone has looked at the Raspberry Pi™ SBC? I've seen some talk about running NETMF on it, but don't know if anyone has taken the Linux compiled version of NETMF and tried it?

Sorry, I know this is not a NETDUINO related post, but I think there are some really smart and creative people on these forums... so what better place to ask.

I'm working on an audio project idea that I'm not sure could be accomplished with ND which is why I am looking at it.

I have been following the Raspberry PI with great interest. As you probably know, they are in extremely short supply and it will be a while (months) before most people can get their hands on one. Also the Raspberry PI has several features like USB host and HDMI video that would require drivers to work with NETMF. Since parts of the Raspberry By are not open source (particularly the Broadcomm chip used as the processor), I would expect the effort to develop drivers for all the hardware will be non-trivial.

In any case I am anxious to get mine, but to run Unix.

How do develop and deploy for the Arduino in Visual Studio:

I too have the HelloPachube example running on a Netendo Plus powered by a wall-wart. It has been running continuously for a couple of weeks now. It runs fine and I can see the data on Pachube. I have definately had a few network hickups as well as outages lasting several minutes. The Netduino has not locked up once. As they say, your mileage may vary ..... Also a big thank you for your great book, I highly recommend it!

Perhaps there is some confusion about "localhost". It refers to the current computer, so if you use localhost on your PC, it refers to the PC. If however you use localhost in your Netduino program it would refer to the Netduino, not the PC. If you want to have the Netduino talk to the PC use the ip address of the PC, not localhost.

Need a project (c#), in breadboard form to include the following:
2 Temperature/Humidity sensors.
1 RFID reader
1 Wifi
1 GPS
1-2 button(s)
1 display 16 x 2

We would all be glad to help you if you re-phrase your question, For example if you stated "I want to use a Netduino and would like to know what GPS, WiFi and Display shields work well with it?" I am sure you would get several well informed answers. As you probably know, shields simply plug into the Netduino (or Arduino for that matter) and generally are able to be stacked on upon another - no breadboard required.

Perhaps you are looking for a solution without any circuit boards? Did you mean you want to use a Netduino mini plugged directly into a breadboard along with other components? Your request is not clear.

Finally you do not state if this is intended as a "one off" project or a pre-production prototype. The reason I ask this is you should consider that there is already a readily available device that has:

RFID reader
Wifi
GPS
button
display

it is called a smartphone. All you would need to add is the two Temperature/Humidity sensors. Are you familiar with the Android Open Accessory Development Kit?

If you would like to discuss this further please send me a private message here on the forum and we can arrange to speak on the phone if you like.

I now have a prototype of a new open source slider module. Here is a photo of two of them:



I also wrote a blog post for slider module.

IBM has contributed an open source implementation of the Paho, a simple protocol for sensor and machine to machine communication via the internet.

See:
http://www.adafruit....hings-protocol/

&

http://www.pcworld.c...ed_devices.html

This looks like a good way to get Netduinos communicating, has anyone used this Paho protocol?

Fabien Royer did a nice blog post on his Netduino-powered Game Console at http://fabienroyer.w...d-game-console/

You mean this one?

http://forums.netdui...4-game-console/

Yes, sorry. (It's still a great project though).

I was able to order five modules and a cable set from Amazon today, and am looking forward to getting this new stuff to play with. After all, one can never have too many Netduinos ;-) I see Chris posted a link to the documentation for the Netduino Go board here on the site. Could you also post the linked to the documentation for the various other components? Thanks.

few months ago I mentioned that the next version of the .Net Micro Framework, v4.2, was in beta, Netduino is opening up to an wider audience with the .Net Micro Framework v4.2 release.

Well it's beta no more!

Version 4.2 RTM Today!! (Updated)

We are glad to announce today the RTM of the .NET Micro Framework version 4.2. You can download the SDK and PK as well as the all sources from our Codeplex project, client_v4_2 branch, at change number 13620. (We will be distributing 4.2 solely through the Codeplex site this time and not on downloads.microsoft.com)

Version 4.2 of the .NET Micro Framework Porting Kit provides the following new features:

Remote Firmware Update: The .NET Micro Framework SDK and PK now support updating your device firmware remotely.
Complete Cryptographic Object Model over PCKS #11: Most types and algorithms used in the desktop framework are now supported. PKCS #11 allows extensibility at the firmware level for adding new cryptographic tokens.
1-Wire, PWM and A/D object model: Support for PWM and A/D operations is now provided as a standard interface. 1-Wire is provided through a community development effort
SNTP and FTP (client and server): Support for SNTP and FTP is provided as a community development effort.
StringBuilder and Regex types: Support for StringBuilder and Regex is provided as a community development effort.
Transcendental functions for doubles in System.Math
VB.NET: The SDK now support VB.NET.
Support for Cortex M3 devices with STM32 processor family samples: The support for the STM32 family is provided as a community development effort and features two solutions for two different development boards. See the Porting Kit for details.
PKStudio: PKStudio supplements SolutionWizard to create solutions for the Porting Kit environment. See the Porting Kit distribution for details. (PKStudio code can be in the community branch under %SPOCLIENT%\CLR\Tools\PlatformDesigner\PKStudio and the binaries are instead in the %SPOCLIENT%\Tools\bin\PKStudio directory ready to use)

...

You can find white papers about crypto, firmware updates, and the Codeplex distribution in general on the documentation page of the project. You can find the general documentation on MSDN. PK documentation is in the distribution, under the documentation directory (you will find there also the full .chm help

This definitely looks interesting, thanks for posting. A Netduino Go module that used their card would be quite useful.

I see Arduino has announced several new products ( http://arduino.cc/bl...ast-at-arduino/ ) including a new Wi-Fi shield.

I wonder if it will be Netduino compatible??

Anyway they will have them at Makerfare in NYC this weekend, so perhaps someone can check them out.

I just ran across this excellent, simple guide to connecting external parts to a microcontroller: http://cq.cx/interface.pl#10

It is not Netduino specific, but would work with any microcontroller.

One caution, in his examples he often shows the voltage level as 5 volts, which would be fine for an Arduino or many other microtrollers. The Netduino is a Netduino is a 3.3 volt device so just replace 5 V with 3.3V in his drawings.

He describe how to:

Light an LED from a Digital Output
Read Switch Contacts with a Digital Input
Read a Digital Signal that Goes from 0 V (LOW) to 10 V (HIGH)
Read (with Opto-Isolation) A Digital Signal
Measure a DC Voltage Between 0 V and 15 V
Measure a DC Voltage Between -15 V and 15 V
Measure a DC Voltage Between 0 V and 1.7 V
Measure the Position of a Potentiometer
Measure an Unknown Resistance
Measure a Temperature
Output Characters on an LCD
Switch a 100 mA, 10 V Load
Switch a 1 A, 10 V Load That Always Stays Connected to Ground
Switch a 10 A, 40 V Load
Switch a 120 VAC Load

I ordered and received one. As a watch goes, it is extremely thick and heavy. It definitely scores major geek points though :-)

Hello Mozsi and welcome to the wonderful world on Netduino!

I am not a Mac person, but I can tell you that having simple routines that allow reliable communication between a microcomputer and a desktop (e.g PC or Mac) is something that virtually everyone struggles with. The key hangup is reliability.

To be useful in the real world communication needs to be resilient; automatically recovering from such things as power failures, cables being unplugged and being plugged in again etc. If that is something you can workout it will be a great service to us all.

I don't know if this helps, but here is a project someone is doing for the Arduino: http://robotgrrl.com...no/matatino.php

Hi,

i want to use my netduino code on an trinamic eval board. it has a AT91SAM7X256 instead of AT91SAM7X512

I believe your biggest problem would be that the AT91SAM7X256 has 256 Kbytes of flash wile the Netduino has 512K. I wouldn't say absolutely that it is impossible to get the .NET MF into 256K, but it would be a major challenge.

Far better to select a chip with adequate memory.

The design surface in Visual Studio for .Net Gadgeteer is very cool, particularly for documenting how the modules are connected. The code generation is of less interest to me for Netduino GO.

Here is a blog post showing how it works.

Has anyone given any thought to having this for Netduino GO?
