#52032 Windows 8.1 on Surface Pro. Debugging issue.
Very odd if MFDeploy works, have you tried changing the deployment method from USB to serial in your VS project settings, save the changes then change back to usb and save your project settings again, then try deploying.

Ahh just saw you fixed it
Glad all is working for you now.
#34910 How to read from a pin that gets a PWM signal
afaik you can't directly access the timers as they are being used by the netmf runtime.
Paul's suggestion of sampling the time would probably work, however the accuracy may be questionable, could you use the adc to derrive the average voltage I.e. 100% duty would be 3.3v etc.

#34905 Netduino plus with nitgen fingerprint scanner(fim5360)
I think the lvcmos is a different part from what the sheet says that said I would be surprised if it outputted 12v as it said it had a 5v supply...
Personally I would use a hex inverter to buffer the rx and TX and see what happens, if needed I would use a max232 and opto isolator to be on the safe side...

#34174 More GoBus news: through-hole GoPort IDC Headers
Im currently building a netduino library for design spark Currently contains:
Any way i was considering porting the lib to Eagle and Kicad as well, if there is enough interest i will see what i can do. Nak.
#34072 Seven Segment Display Module
Hi Matt
In the past i have always used an led to indicate overflow, but i guess thats not an option with the current display design, that said could you illuminate one of the decimal points to indicate overflow?

#32336 Problem Detect the presence of SD in Netduino Plus
Hi
Try adding a reference to Microsoft.SPOT.IO Also you could use the events in the RemovableMedia object to detect insert and eject i.e.
public static void Main(){
RemovableMedia.Insert += new InsertEventHandler(RemovableMedia_Insert);
RemovableMedia.Eject += new EjectEventHandler(RemovableMedia_Eject);
Thread.Sleep(Timeout.Infinite);
}
void RemovableMedia_Eject(object sender, MediaEventArgs e) {
Debug.Print("Ejected");
}
void RemovableMedia_Insert(object sender, MediaEventArgs e) {
Debug.Print("Inserted");
}

#32204 SIM900 Library for Netduino
Hi s0n1k
I Assume you mean one of these?
http://imall.iteadst...m120417009.html
If so then there must be an existing .net driver as the FEZ Panda II is listed as compatible, and if it builds for one netmf device it should build for all. By the looks of that particular board you should be able to configure the serial interface to match the pins on the ND+ using the "UART multiplexer" jumpers you would want to either use D0 and D1 or D2 and D3, after that as its controlled by AT codes, just send the relevant strings over the ND's serial port and your in business.

#32178 Netduino Go with MMA7361 Accelerometer
Hi Hoquet
Looks like you have the hard parts sorted
I would suggest some normalised sampling, i.e. report the average of 5 readings, or take delta's between each reading, the delta should be able to give some indications of magnitude and direction of movement i.e. -ve number indicates movement in one direction, +ve movement in the other and 0 = no movement.
If you round your results to fewer decimal places you will see that all the numbers remain static i.e. your X measurement is 0.49 for each of the posted responses which would indicate that it is at rest on a flat surface.
Now as for translating the readings into degree's i would imagine that their is details in the datasheet for the accelerometer for translation into standard units...

#30527 Socket error #10055 (WSAENOBUFS)
Doesn't seem to make any difference for me I'm afraid  However the plot thickens... I do not need the thread.sleep at all if and only if the message i am sending is > 21 bytes in length.... Quite why such an arbitrary length works is any ones guess, which leads to workaround #4 If the line is less than 21chars long pad with spaces to make it 21 chars long Here is the code i got going, as you can see i simply added spaces to the end of the string and tested the ANSI codes work with a padded string by setting the background to red and it seems to work ok, admittedly I have done nothing about the formatting but that was never the issue here using System.Net;
using System.Net.Sockets;
using Microsoft.SPOT;
using Microsoft.SPOT.Net.NetworkInformation;
namespace NetworkTest {
public class Program {
public static void Main() {
// Prints out all IP addresses
NetworkInterface[] Ips = NetworkInterface.GetAllNetworkInterfaces();
for(int i = 0; i < Ips.Length; ++i)
Debug.Print(Ips[i].IPAddress.ToString());
// Listens on the port 23
Socket Listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
Listener.Bind(new IPEndPoint(IPAddress.Any, 23));
Listener.Listen(1);
// Accepts the first connection
Socket Connection = Listener.Accept();
// Stops further listening
Listener.Close();
// ANSI modes: Normal, Forecolor: White, Backcolor: Red ( as String(): "\x1b[00;37;41m" )
byte[] AnsiData = { 27, 91, 48, 48, 59, 51, 55, 59, 52, 49, 109, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32 };
// Text ( as String(): "Hello World!\r\n" )
byte[] TextData = { 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33, 32, 32, 32, 32, 32, 32, 32, 13, 10 };
while(true) {
Connection.Send(AnsiData);
Connection.Send(TextData);
}
}
}
}
Forgot to copy code to notepad first so lost all formatting and got a load of RTF color coding instead Nak.
#30519 Socket error #10055 (WSAENOBUFS)
Hi Stefan
I have managed to repro the issue on a netduino here. Having played with the demo code it does appear that the Send method is returning before the ND+ has actually finished transmitting to the endpoint. Adding a Thread.Sleep(100) between each send seemed to fix the issue for me, so i hypothesise that some sort of delay is required to allow the ND+ to shift the data out. Given that this is a telnet server i wouldn't expect this to be much of a problem due to the relatively slow response times between messages... That said i think a bit of a change in architecture would make a more useful as you could add reading to the network comms thread as well, then just lock and sync a pair of queue's between the main and network comms thread.

#30425 Public repository for Firmware
Hi All
Is there a public repository for ND firmwares?
netduino.codeplex.com seems to be pretty much dead in terms of commits
I would really like to be able checkout firmwares in the same way as I can with netmf, especially with the possibility of GCC compilable firmwares for the GO I think the amount of interest in the firmware source will increase. Also it would be really neat to be able to fork customised firmwares i.e. GO firmware with OpenSSL enabled or similar.
It is the one aspect of netduino that i find to be quite blackbox, i.e. i would love to move over to using 4.2 due to the GC and memory management fixes more than anything else, but I cant as my immediate project relies on a firmware modification for acceptable performance.
However as it stands i can only use the latest production firmware as that's the only source I can find released.
Also wouldn't an issue tracker be a more suitable place to report bugs and feature requests than this forum?
Sorry if it sounds like a bit of a winge i'm just banging my against another system.outofmemory exception i know disappears with 4.2 (tested codebase with 4.2 all works flawlessly apart from the low level SPI hack I implemented in the firmware which is really needed to achieve acceptable performance)
