Take a look at the link you posted. VS 2013 is there. VS 2012 updates are there. VS 2012 Express edition for Windows Desktop is not there.

This is a problem for me because I just re-paved my laptop and now cannot seem to get a decent download link for VS 2012 Express, only 2013. Not good to keep this stuff out of sync...

I have an LCD serial display for connection to my Netduino2+, so I think I will have a problem also connecting a serial clock, is that correct? is this page - http://blog.codeblac...d-with-I2C.aspx - accurate still in 2013? Thanks.

Can anyone recommend a time keeping solution for a non-networked Netduino Plus 2 that does not require soldering anything anywhere? I have seen a few kits from some favorite vendors, but nothing ready-to-go.

 

 

Thanks.

 

I did a quick search and found

 

http://www.tinkerkit...duction-to-dmx/

 

and

 

http://en.wikipedia.org/wiki/DMX512

 

which says

 

DMX512 (Digital MultipleX) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It

was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards.

 

 

Now if only Secret Labs would make a fog machine....

Can anyone recommend a TTS shield/part/etc and driver that would work with a Netduino Plus 2?

Thanks.

Hey all. I am trying to find a source for an HD47780 LCD display that will do 20x4 that does not require soldering.

I saw this blog post:

http://10rem.net/blo...th-the-netduino

as well as the codeplex library, but cannot seem to find anything on the "usual" online retail places that have the part I can wire up to a breadboard, and then a Netduino //+, without soldering anything.

All ideas appreciated.

Thanks.

Hi all. I only recently discovered the Netduino platform 3 days ago, and am very happy that I did! Please excuse any part of this post that reeks of ignorance. I am trying to come up with a "different" way of timing a pinewood car race. For those not intimately familiar with it, a set of hand-carved wood cars roll down a track, and the one that gravity and aerodynamics treats the best wins. In contrast to the awesome++ work done my Jarrod Sinclair, I am interested in doing something like this (there are 4 lanes on the track): 4 sensors at the top of the track, each registering datetime when a car rolled over them, saving it at "start time" for lanes 1/2/3/4. 4 sensors at the bottom of the track, each registering the datetime when car rolls over the track, saving "finish time". The Netduino Plus 2 would be set at the bottom of the track with a monitor to display the TimeSpan difference for each lane. So...... Do (flat low profile?) sensors exist that register simple touch impact? Can 8 be wired to a Netduino 2 (plus?)? Is this a crazy idea? I am just now reading over some "getting started" text to get familiar with the platform. I appreciate ideas and input on this. Thanks!

@qsnapper, thanks for providing input. I was unable to get that to work with my configuration for some reason. I did not have the right reference assemblies loaded up to get those WebClient bits to work.

 

I used  Toolbox.NETMF.NET.HTTP_Client this way:

 var httpClient = new HTTP_Client( new IntegratedSocket( _remoteCollectionSite, 80 ) );                fullUri = _remoteCollectionPath + _paramBuilder.ToString();                HTTP_Client.HTTP_Response httpResponse = httpClient.Get( fullUri  );                Debug.Print( _remoteCollectionSite + fullUri );                Debug.Print( httpResponse.ToString() + "n");

However, if the remote server is not available the exception that comes from a timeout is not easy to trap. I might be having a problem with how Exceptions are caught in my catch{} block because I never get details as I am used to when creating .NET (non Micro) Framework software.

 

Thanks.

There is a remote web server waiting to accept simple HTTP GET traffic and I want to make calls to it from my Netduino Plus 2. I am familar with using WebClient in the .NET Framework, but do not see anything comparable for the Micro Framework.

 

What is the proper way to just send a GET from a Netduino? I just want to send stuff like

 

http://192.168.1.1/g...a=1&b=2&c=3&d=4

 

from the Netduino to my remote web server.

 

 

Thanks

Hi Donovan. Both that part and then one at https://www.sparkfun.com/products/9568 seem to require 5V. How did you deal with that?

Thanks.

I was looking at this

 

http://www.makershed...t_p/mkmts01.htm

 

 

Thinking that it might be valuable to have a Netduino Plus 2 attached and powered by it, and have that plugged into my AC outlet (I am in USA), so if the power goes out for any period my Netduino will keep running.

 

All comments appreciated.

 

 

Thanks.

 

 

Very cool. As a newbie, I am trying to read http://search.murata...mmended_Circuit to understand what resistors to wire-up inline with that buzzer (still not fully grokking schematics). Is there a "Fritzing style breadboard view" that shows how to wire up that Piezo part?

 

Thanks.

Can anyone recommend a piezo buzzer/speaker part from any supplier (Adafruit, Sparkfun, Amazon, etc) that works well with the Netduino Plus 2?

 

Thanks.

I have seen "premium jumper wires" on several online stores, none seem to e longer than 300cm / 12in. Why is that? Power loss? Potential for signal interference? Thanks.

When I need something "long" (eg 48 inches), would it be ok to use a piece of shielded Ethernet cable, or would that add additional complexity to the job of just making a sound connection? Thanks.

I have a Netduino 2+ that will communicate over ethernet. The ND will have a AC power, and the ethernet switch is also powered by AC. I wanted to find an LED lamp that could be powered by the switch, thinking it would be good to have one less thing in my surge protector.... But web searches have turned up nothing as simple as a lamp that can be powered by a typical switch. Can anyone say why no such devices seem to exist? Thanks.

I apologize for my lack of clarity. I am not asking about PoE. I am asking about using a simple ethernet switch (or hub) with "n" RJ45 twisted pair connections, being able to power a simple light. I understand that there is not a lot of power in each switch port, but I was guessing (hoping?) that maybe using 2-3 of them together could power an LED lamp of some kind. It seems like a simple utilitarian thing, but no one seems to make (or bg about home brew) such a device. Thanks!

What would be the benefit/drawback of connecting two Netduino units directly for communication? I have no real application in mind, just thinking that there might be a use to say have a 'mini detect a certain condition and then push a signal to a Plus 2. Just a random thought. All comments appreciated.

 

Thanksk.

 

Hs anyone discovered anything new bout this product with the Netduino?

I have gotten a lot of mileage out of .NET using Mocks for unit and integration tests in Visual Studio.

 

Is there an equivalent for the Micro Framework?

 

My eventual goal is to read from 4 sensors and do something with the captured information. Before I get to that goal, I was thinking that I could exercise the other parts of the system by creating "fake inputs", injecting known data into their structures/wrappers, and then debugging with that fake stuff.

 

Is that possible?

 

 

Thanks.

 

This looks really cool.

Could 4 sensors be connected to a single Netduino Plus 2? I am thinking of using a set to collect simultaneous data at the same time; 4 are lined up within 1" of each other, pointing at the sky, and when something rolls over each one, the Datetime could be saved/displayed for each acquisition.

[EDIT]

The title should be "Large LED for Scrolling Tweets" but iOS autocorrect bit me again. And I don't seem to be able to edit the title or delete bad posts.

[EDIT]

 

 

I am probably getting ahead of myself since I am only past the 2nd blinky experiment, but I was wondering where I might be able to find a ready-to-plug (no soldering required) serial LED display that would emulate this on a Netduino+2: https://sites.google...tmatrixdisplay/ My general web searches have not turned up anything decent, and Sparkfun and Adafruit don't seem to have anything available. All ideas appreciated, thanks!

Chris, thanks for taking a look at this. I am putting in a big chunk of the program in the hopes that you can help me think though the right way to do eventing. This is code for a model car race track; a switch is closed and a race starts, when a car passes over a light sensor the time is logged, and if nothing happens in 10 seconds then the time is logged anyway and then a new race heat can begin.

// extraneous code removedpublic class Program{    private static InterruptPort _laneSensor = null;    private static InterruptPort _buttonOnboard ;    private static InterruptPort _gateSwitch = null;    private static Timer _heatTimer;   	 public static void Main()        {            OnboardHardwarePrep();            SensorsReset();            StartGateSwitchPrep();            TimeContainerPrep();            Thread.Sleep( Timeout.Infinite );        }                private static void OnboardHardwarePrep()        {            _ledOnboard = new OutputPort( Pins.ONBOARD_LED, false );            _buttonOnboard =                new InterruptPort ( Pins.ONBOARD_SW1, true , Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeBoth );            _buttonOnboard.OnInterrupt += new NativeEventHandler ( buttonOnboard_Fire );            _ledOnboard.Write ( false );        }                            private static void SensorsReset()        {            try            {                _laneSensor = new InterruptPort( Pins.GPIO_PIN_A1, false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeBoth );                _laneSensor.OnInterrupt += new NativeEventHandler( laneSensor_Fire );            }            catch (Exception xxx)            {                Debug.Print( xxx.ToString() );                // Why do I only get the text "System.Exception" and not rich problem info?            }        }                private static void StartGateSwitchPrep()        {            _gateSwitch = new InterruptPort( Pins.GPIO_PIN_D12, false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeBoth );            _gateSwitch.OnInterrupt += new NativeEventHandler( gateSwitch_Fire );        }                        static void gateSwitch_Fire( uint data1, uint data2, DateTime time )        {            RaceHeatBegin();        }                            static void RaceHeatBegin()        {            _ledOnboard.Write( true );            TimerCallback timerCallback = new TimerCallback( Tick );            _heatTimer = new Timer( timerCallback , null , 9999 , 9999 );            _laneTimeBegin = Utility.GetMachineTime().Ticks;            _ledOnboard.Write( false );        }                                static public void Tick( Object stateInfo )        {            Debug.Print( "Timer elapsed for the heat (9.999 seconds)." );            buttonOnboard_Fire( 0, 0, DateTime.Now );        }                static void buttonOnboard_Fire( uint data1, uint data2, DateTime time )	    {            try            {                if (null != _heatTimer)                {                    _heatTimer.Dispose();                }            }            catch (Exception xxx)            {                Debug.Print( xxx.Message );            }            TimingLog();            _ledOnboard.Write ( false );       		 }	   	             private static void MessagePrint( string messageToSay )        {            Debug.Print( messageToSay );            buttonOnboard_Fire( 0, 0, DateTime.Now );        }                        static void laneSensor_Fire( uint data1, uint data2, DateTime time )        {            _laneSensor.OnInterrupt -= laneSensor_Fire;            _laneTimesEnd[1] = Utility.GetMachineTime().Ticks;            MessagePrint( "Lane 1 : " + _laneTimesEnd[1] );        }            }

Also, the Micro Framework appears to throw and Exception if a property is assigned to an Interrupt port more than once (a tactic I tried in order to "reset" the hardware). Is that as-designed behavior?

 

Thanks.

  Personally, I would use a photo-transistor instead, it is easier to use and it will work much better.  

 

Thanks for the detailed response. I have re-evaluated what I am trying to do... And now am shopping for "photo transistors". My typical part suppliers have been Adafruit and Sparkfun, neither of which appears to carry what you are talking about. Do you have a vendor recommendation?

 

 

Thanks!
