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)?

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

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

Interested in meeting up?

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

http://www.adafruit....-visual-studio/

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.

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

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.

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

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

Indirectly related, here is a blog post about the Beta of the NETMF port to the STM32 F4.

Additional information on NETMF for STM32.

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?

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 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.

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

Very nice tutorial, it got a tweet from me ;-)

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.

The code is far from 'perfect' but seems to work OK. There is one known issue. On rare occasions, the message string sent to the Netduino for setting the PWM has missing data. The Netduino will return a message informing you of the problem. To be blunt, I have no idea why, but at least it does not happen very often. I live near the BIG Chicago airport and I have issues with electronic items in the home at times. I 'think' it is from aircraft transmissions of some sort. Anyway, a plane is usually flying over and then have strange thing happen around here. Like hear voices on the TV and FM radio.

The usual way to handle situations like this, (namely sending data over noisy communications channels where the message can be garbled) is to include a checksum ( http://en.wikipedia.org/wiki/Checksum) with the message.

Basicly the sender computes the checksum and includes it with the message. The receiver then gets the message and re-computes the checksum to confirm that the computed value matches the checkum received. If they do not then the receiver knows the message has been corrupted and treats it accordingly. (One standard practice is to simply ask the sender to re-send the message).

This may or may not be overkill for your purposes.

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.

Hello Avax,

Welcome to the Netduino forums.

In the past there has been some discussion of CANbus, but I don't know what the current state of that interface is for Netduino.

I do know there are several people (including myself) who would like to see it on the Netduino.

Hopefully others may provide more detailed information.

Hi everyone,

I am a total newbie here.

I have a project I am working on involving LIDAR. The laser measurement device supports CAN bus and I would like to communicate with it using CAN.

I like the netduino platform because I am an experienced .net developer and would like to stay in visual studio if possible.

Anyway I did a search here on "CAN" and nothing came up, but it very likely could be a filtered word like "the".

If anyone has any information on an existing project or thoughts on what hardware would be required to communicate on a CAN bus it would be appreciated.

Regards
Avax

I have been looking at Go module development and can see that another tool in people's toolset is a logic analyser would you say that this is he case?

With this in mind I was thinking of getting the sparkfun bus pirate as it's quite cheap. Would you say that this is a worthwhile purchase?

Cheers,

Mike

Have you checked out http://dangerousprot...-pirate-manual/ ?

Keven is correct that a logic analyzer is a great tool, and will do more. That being said, the stuff from dangerous prototypes can't be beat for the money. $30 for the bus pirate is very cheap; of course you will probably want to buy some cables etc which will bring the price up some.

You may also like their logic sniffer - http://www.seeedstud...2.html?cPath=75 At $50 it too is very attractively priced.

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).

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?
