Hello guys. Could you suggest me cheap LCD to work with Netduino. Without soldering. Just plug to Netduino or breadboard and play with it. There are a lot of this stuff on eBay. I don't know which one is fully supported.

Here is link fom ebay:
Mylink

I am getting visual studio RC 2012. I was wondering if .NET MF 4.3 will supporting?

regards,
supra

When ever a program that I am trying to deploy stops (breaks) due to an error or exception, attempting to look at the line of code that caused the problem will cause Visual Studio 2010 to close and restart.

The break can be from something like trying to put too many bytes into a string. It makes debugging difficult.

Does anyone know a solution to this problem or having the same problem? I have seen some are having BSOD issue but I am not currently having that problem.

Thanks,
Chuck

U can't used vbcrlf. So use char(0)

Hi,

 

I wired up 1 button using this http://arduino.cc/en/tutorial/button.  It works great.  

 

However, I want to wire up more than 1 button.  So I want button 1 to trigger D0 and button 2 to trigger D1 for example.

 

Anyone have any ideas?

 

Thanks!

 

Carsten

Thank you, now it works.

Thank you. I saw u in chat room and u left immediately.

it's a full sized flash object here. Takes a while to load, but it shows stuff.

Thank, Stefan. It took me 5 minutes

The e-brochure link doesn't work. Completely blank

Did u try this link?
what_to do


Mine is working already and had no pb .

U better c him(gutworks)

remove colon
a = a And Not(1 << 7);


to


a = a And Not(1 << 7)

BTW, I can even converted frm proteus, mplab, mikroC/mikroBasic to VB.Net

Thank, chris. My NGo is workin fine

What's the maximum size micro SD card I could use, also 2GB?

The maximum micro sd card frm 2GB to 16GB.

There is another one unlimited size card to 64GB frm ebay seller.

Did anyone saw the cars on parking lot?  When the fireball exploded, suddenly the cars on alarm system automatically turned on. You will see headlights flashing. Why is that happened?

Hi everyone,

I am using the Netduino Plus with the latest firmware (4.2 RC5). I updated everything successfully and my developer experience is very smooth under Windows 7 (64bit).

Now I would like to develop under Windows 8 (RP/64bit) so I installed the same tool chain (VS2010 pro, .NET MF 4.2 and Netduino SDK 4.2 64bit).

I am having troubles debugging my program as every time I start the debug, I get the message:

The debugging target is not in an initialized state: rebooting...

I can see the board rebooting multiple times until I get the error:

The debugging target and the debugger engine failed to initialize because of unspecified device errors.
The debugger engine thread has terminated unexpectedly with error 'Could not reconnect to the debugging target after rebooting it.'.

My program is correctly deployed and runs as I can attach the debugger and see the outputs.

If someone had a similar issue I would really appreciate any advice to help fixing it. I understand Windows 8 is not yet supported (this is why I posted in the "Beta" forum).

Windoiws 8 will be relased this falls

.Net framework 4.3 will be released after window 8

Sneak peak at continued NETMF integration, Express Edition info

It is not necessary to used diode for motors whenever you used 754410 or any other IC chips.

I'm using NGo. There is no need to add resistors. The TTls can handle up to 20mA. There is something wrong with code.. I can only do short code in order to reduce file size.

"The windows 8 computer also has VS 2012 installed.I am not sure if that could be a factor. Any Ideas on how to get the VB.NET project types working?"

 

The VS 2012 is 64-bit only, and computer must be 64 bit. And not 32 bit

 

I am using VS 2010/XP with 32 bit. And cannot upgrading to Window7/8.

 

So i have to buy new computer that comes with 64-bit and USB 3.0.

Hi Guys,

Do you guys know if this MUX Shield will work with the Netduino Plus.

I mean physically.

And does anyone know if there is a library for this guy?

Nope! I haven't tried this
WOOOOOOOOooooooow!. 48 input/output. Let me c.......good ideas...... I can do 24DOF

hello, We are upgrading to 4.3 but now we get a error bitwise shifting in Visual Basic to get the time from a NTP time server. This is old code and always worked in 4.2

 

 

 

Dim lIntPart As Long = 0 Dim lFractPart As Long = 0

For i As Integer = 0 To 3 lIntPart = (lIntPart << 8) Or ntpData(bOffsetTransmitTime + i) Next   For i As Integer = 4 To 7 lFractPart = (lFractPart << 8) Or ntpData(bOffsetTransmitTime + i) Next  

 

Error 1 Type 'System.Nullable(Of )' is not defined. (The error is under the << 8)

 

Does anyone knows why and also there is a buildin function in the SDK 4.3 for calling the time server.

How can we call this function?  

Public Shared Function GetNetworkTime() As DateTime	Dim ep As New IPEndPoint(Dns.GetHostEntry("time-a.nist.gov").AddressList(0), 123)	Dim s As New Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp)	s.Connect(ep)	Dim ntpData As Byte() = New Byte(47) {}	' RFC 2030	ntpData(0) = &H1b	For i As Integer = 1 To 47		ntpData(i) = 0	Next	s.Send(ntpData)	s.Receive(ntpData)	Dim offsetTransmitTime As Byte = 40	Dim intpart As ULong = 0	Dim fractpart As ULong = 0	For i As Integer = 0 To 3		intpart = 256 * intpart + ntpData(offsetTransmitTime + i)	Next	For i As Integer = 4 To 7		fractpart = 256 * fractpart + ntpData(offsetTransmitTime + i)	Next	Dim milliseconds As ULong = (intpart * 1000 + (fractpart * 1000) / &H100000000L)	s.Close()	Dim timeSpan__1 As TimeSpan = TimeSpan.FromTicks(CLng(milliseconds) * TimeSpan.TicksPerMillisecond)	Dim dateTime As New DateTime(1900, 1, 1)	dateTime += timeSpan__1	Dim offsetAmount As TimeSpan = TimeZone.CurrentTimeZone.GetUtcOffset(dateTime)	Dim networkDateTime As DateTime = (dateTime + offsetAmount)	Debug.Print(networkDateTime.ToString())	Return networkDateTimeEnd Function

how do i write button on NGo board to reset it? inputport button = new InputPort(Pins.ONBOARD_SW1, false, Port.ResistorMode.Disabled); Btw could be? var button = new InputPort(Pins.Button, false,Port.ResistorMode.Disabled);

I was going to do this weekend. But i have NGo and shield base. Reasoning is y I was upgraded yesterday. That took 3 mnths.

I don't know what board do u gave N, N+ or NGO.

Right now i'm doing 8x32 dotmatrix (bi-color red/green) either 74hc154 or 74hc595 and no other components. U do not needed driver
JUST 74HC154 and 74HC595 and that all.

I was looking @ ur sample. But u r using 74hc595 i assumed that. And u don't know how to write code for dotmatrix.

Here is sample code for dotmatrix. But don't try this. It is written in mikroBasic. I will try to convert to Dot Net Framework.

const supra as byte[30]  = (
          $00, $46, $49, $49, $49, $31,' // S
          $00, $3F, $40, $40, $40, $3F,' // U
          $00, $7F, $09, $09, $09, $06,' // P
          $00, $7F, $09, $19, $29, $46,' // R
          $00, $7E, $11, $11, $11, $7E)' // A

If u want to c my youtube. I'm using 74hc154. Its easier to write
dotmatrix 8x32


I have 9 samples for 74hc154. Also i have small code for 74hc595( u can enter string).I do not have youtube for 74hc595.

Do u have VS2010? I have Library written in C

I am not sure if ur 7 segment is Common Cathode or Common Anode and not sure if it is serial or parallel.

Here is tutorial for code and table written in C.
Mylink


Also I do not have max7219. But i do have 74HC595 with 4 and 6 digits

@stefan
it is ok with this?
InterruptPort button = new InterruptPort(Pins.Button,false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeBoth);
