• Problems with signal followed during sampling of the signal

  Hello

  I'm relatively new to LabVIEW 8.0 and I'm having a problem with being able to monitor the signals that I am gaining two simultaneous analog signals.  I have the user to input the frequency of sampling and the length of the sample, and then I starts the scan, but when running the analysis, I don't see no result on the chart if the duration of the sample is passed, at which point all data comes.  Previously, I could see the acquisition of real-time data and I don't know what I've done since then have possibly that stop working.  I tried to introduce a kind of late for may allow the software to apply the data to the graphics, but I had no success.

  I have attached the VI of the data acquisition component.

  Thank you so much for reading this.

  Hello

  I suggest you try these two options:

  1. in each iteration of the while loop, add your data to the data of the previous iteration, IE use a shift register to create an Adrien to data that you have acquired. When you save the data in a file, read data from the table and not the current value of the waveform. You can read the data in the table by using a queue, or by using any simple method to pass data between the blocks.

  When you use a local variable of the waveform card, you only read the current value in the array, not its history.

  2. use a property of waveform graphs node to read the history of the ranking, convert the picture from picture to picture 1 d 2D using cluster of waveform ungroup functions and write to the file, click on "Save".

• New Dell Inspiron 1764: Problems with signal low connection to wireless networks.

  I have a new laptop Dell Inspiron 1764 I received on 25 June. It is "replace" a Dell Inspiron 9100, who has learned to be too slow and too bulky for my needs. For the purposes of support, the two laptops are running on Windows 7.

  Overall, I love my new Inspiron 1764. However, I noticed the connection/signal strength seriously degraded, with wireless (Dell Wireless 1397 WLAN Mini card) card, compared to my Inspiron 9100 (Dell Wireless 1350 WLAN Mini-PCI card).

  In areas of my home that my 9100 can obtain the power of the complete signal (5 bars), my new 1764 bars 2 or less. This behavior is not as limited to only my house as I have tested in my work and in an area of less than 10 feet away from the wireless router, I have 'Internet connectivity problems.

  I tried twice this morning talk with Dell technical support. The first person I talked to tried to be helpful and initiated at least a DellConnect session with me so that he can check out some of my settings and such (However, why they went twice in my sharing settings I could not determine as they have absolutely nothing to do with the intensity of the signal).

  Unfortunately, I was disconnected from the session when I went to a place that had less signal than just next to my wireless router.

  I then go on the chat support with Dell and received another technician to speak with. I explained my problem, told them that I was in a DellConnect session with the other technician, and they looked to the top of my support contract.

  They then told me that my warranty does not cover software issues and referred me to the software Department and said it would be a supplement. I told them that I did not believe that it is a problem of software in any way, shape, or form. They told me that it must be a matter of adjustment. I spent several hours scouring the internet forums on Dell and other sites check those who have had similar problems. Some of their questions were certainly the software settings, but I still don't yet to find anything that tells me I have an incorrect setting of software.

  So far, I'm standing in my kitchen, tapping on my Inspiron 9100 with a full 5 bars, while my Inspiron 1764 is sitting next to me with a skinny 2 bars, and I am literally standing 7 feet above the room which houses my Linksys WRTU54G-TM router.

  Personally, I suspect a faulty wireless card, but how to convince Dell to hear my case and replace it instead of trying to bilk me for support of useless software?

  I hope Dell Tech Support bed actually this post, or people with the same problem can Dell refer to my previous post describing the problem and the fix.

  It IS a PROBLEM of MATERIAL WITH the ANTENNA, AND VERY PROBABLY THE DIFFERENCE BETWEEN a DECK CONNECTION at the ANTENNA of the PLATE, from connections TAPE FOIL INDIVIDUAL at the ANTENNA of the PLATE, THAT DELL MUST HAVE RESPONSE BETWEEN WHAT MINE PORTABLE has BEEN CARRIED OUT AND THE SPARE ROOM WAS MADE. THE PROBLEM IS NOT SOFTWARE, PROVIDER OR ROUTER, IT IS THE PLASTIC WITH THE ANTENNA CASE!

  Dell is in fact losing more money with the hours of technical support through software patches and sending technicians with new wireless cards that does not solve the problem. They need to send and replace the plastic case behind the LCD screen with the updating of antenna and connections.

  Good luck!

• Problem with signals TTL metering: confused with counting

  Hello

  I use a TTL of 0.2 Hz signal to synchronize two devices. I use a Usb-6210 card to count the pulses TTL. The meter goes off when it detects the edges increase. In my case, the meter was sometimes triggered at low altitude, which causes wrong results (see attached pictures, the TTL signal is sampled at 20 Hz and the dots represent an increment of the counter). How can I solve this problem?

  In addition, the cable that connects the TTL output was welded by myself, would that be a problem of bad contact?

  Thank you very much

  K-X

  What is the nature of the device producing the TTL trigger signal?  Is it possible, for example, that it could produce a 1 microsecond pulse (which might not be visible on your signal ground) that would trigger the meter?  You really produce a digital pulse (i.e. your something circuit which is 'on' or 'off' as opposed to 'product analog voltage in the range of 0 to 5 volts')?  Are there any other devices around that could produce the impulses that are "picked up" by your meter?  The cable connecting the TTL is armored pulse for the meter?  The shield is based at one end?

  These questions (and the previous) suggest that the problem may be 'electronic' rather than 'LabVIEW '...

• problems with signal activeTabChanged

  Hello

  Ive tried to trigger an action when some tabs are launched for this that I though "Hey the activeTabChanged signal is perfect!", but for some reason any (I may implement the wrong way) it ever triggers the signal.

  That's how I apply:

  QObject::connect (tabbedPane, SIGNAL (activeTabChanged(Tab*)), this, SLOT (sectionTriggered(Tab*)));

  void App: {sectionTriggered (bb::cascades:Tab * activeTab)}

  activeListURL = activeTab-> objectName();

  getList();

  }

  Am I missing something? I have debug and put a breakpoint in the slot, but he never reached the point...

  OK, I found that the solution just had to connect the signal like this:

  QObject::connect (tabbedPane, SIGNAL (activeTabChanged(bb::cascades::Tab*)), this, SLOT (sectionTriggered(bb::cascades::Tab*)));)

  (including the "bb::cascades:" part) even though the qde described it as an error...

• Problem, the signals and Slots

  Hi, as I posted in one of my other posts I have following problem with signals and messages and would be nice if someone could clarify anything that I don't seem to be able to find what the problem of the outputs.

  I have the code:

  void MYNetworkClass::requestFinished(QNetworkReply* reply)
  {
  
        // Check the network reply for errors
        if (reply->error() == QNetworkReply::NoError)
        {
           // read response
           const QByteArray response(reply->readAll());
           qDebug() <<"Response: "<< response;
  
           JsonDataAccess jda;
           QVariantMap results = jda.loadFromBuffer(response).toMap();
  
           QVariantMap data = results.value("SomeData").toMap();
  
           emit signalSuccess(data); // I reach here .... 
  
  // however actually when I click "Step Over" in debug mode, and try to exit the function// afterwards I get such "error" saying: No source available for "QMetaObject::activate() at  0xb9668da7" - highlighted in red.
  
       }
       else
       {
           qDebug() << "\n Problem with the network";
           qDebug() << "\n" << reply->errorString();
       }
  

  In MyNetwork class I also added the definition of signal in the header file:

  signals:
  
      void signalSuccess(QVariantMap result);
  

  Now also when someone calls an object MyNetworkClass method which calls requestFinished,.

  I want to catch the signal which is emitted by the requestFinished - as shown above.

       MyNetworkClass *network = new MyNetworkClass();
  
      QMap params;
      params.insert("username", userEmail);
  
      bool res = QObject::connect(network, SIGNAL(signalSuccess(QVariantMap)), this, SLOT(SomeSlotForSignal(QVariantMap)));
  
          Q_ASSERT(res);
      Q_UNUSED(res);
          network->makePostRequest("Login");
  

  My problem is that the SomeSlotForSignal slot never is called... (even if the signal is issued constitute requestFinished method and as I stated SomeSlotForSignal as a crack in the header file...) What can be problem? Any help? Thank you.

  I guess I solved the problem.

  The code I presented previously registered function

  F of a class B:

   void B::f()
  {
  MyNetworkClass *network = new MyNetworkClass();
  
      QMap params;
      params.insert("username", userEmail);
  
      bool res = QObject::connect(network, SIGNAL(signalSuccess(QVariantMap)), this, SLOT(SomeSlotForSignal(QVariantMap)));
  
          Q_ASSERT(res);
      Q_UNUSED(res);
  
  network->makePostRequest("Login");
  }
  

  Then the function f is called to:

      B object;
      object.f();
  
  The problem was I think that when the server responded "object" was destroyed from the stack. When I replaced the above code, with 
  
       B* object = new B();
      object->f();
  
  I think it works now......
  

• Problem with P10-873 SD Slot

  I'm having a problem with the slot SD on my P10. The problem is that when I insert an SD card, it reads the card and keep reading. Then, the computer stops responding. When the computer finally answers I get an i/o device error.

  Any ideas how I could get this to work? I've had the problem since I bought the PC and tried several SD cards, brand new and very functional. I tried to uninstall and reinstall the driver for it on the CD and also the Web site with no luck. When I did this, the computer would read then don't detect any card and stop playback.
  Then I reinstalled again and I'm back to this old problem.

  The SD slot is installed as "SDA Standard compatible SD host controller."

  When I insert the card, it appears as "Secure digital storage device." If I try to change the driver for this I get two options:

  > Version: 6.0.4064.1 [2002-01-10] SD storage card

  When I use it, the card is read and read continuously until an IO device error appears. The ocmputer does not respond within the interval.

  > Version: 6.0.4069.1 [2002-01-10] SD storage card

  When I use it, a yellow exclamation point appears on the SD card in the Device Manager and the error message indicates that the device failed to start. Even after a reboot, same problem.

  Any help would be appreciated, thanks.

  Post edited by: hamidelaosta

  I just found out that the problem was caused by Norton Antivirus. The problem was that norton is set to scan all removable media for boot sector viruses, this is for a reason any causes the SD card to stop responding for a very long time, and then causes an error of e/s. I have disabled removable media scanning and it's working now, at the expense of some system of protection.
  Hope this helps someone find something else that they have problems with this.

• Graph - problem with battery

  Hello

  Ive got 3 problems with stack slots:

  2. always when I remove only one value (in this case), the last chart is remove

  3. when I turn the button second stop (the rest is on), the name of the track in the legend is double.

  Does anyone have an idea what I can do with that?

• Problems with GPS signal/slot

  Hello

  I try to get GPS information for my application. I did a class to do so.

      virtual ~GPShandler();
  private Q_SLOTS:
      void positionUpdatedSlot(const QGeoPositionInfo &geoInfo);
  
  public:
      void start();
  
      void stop();
  
      double Latitude();
  
      double Longitude();
  
  private:
      double mGeoInfoLat;
      double mGeoInfoLong;
      QGeoPositionInfoSource *mGeo;
  };
  #endif /* GPSHANDLER_H_ */
  

  #include "GPShandler.h"
  
  GPShandler::GPShandler(QObject* parent)
  : QObject(parent) {
      mGeoInfoLat = 0;
      mGeoInfoLong = 0;
      mGeo = QGeoPositionInfoSource::createDefaultSource(this);
      if (mGeo) {
          bool checkval = connect(mGeo, SIGNAL(positionUpdated(const QGeoPositionInfo &)), this,
                  SLOT(positionUpdatedSlot(const QGeoPositionInfo &)));
  
          mGeo->setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods);
          mGeo->setUpdateInterval(1000);
  
          //checkval = mGeo->setProperty("backgroundMode", true);
          //int i = 3;
      }
  }
  
  GPShandler::~GPShandler() {
      // TODO Auto-generated destructor stub
  }
  
  void GPShandler::positionUpdatedSlot(const QGeoPositionInfo &geoInfo) {
      // Here's where you can do something with the device's position
      mGeoInfoLat = geoInfo.coordinate().latitude();
      mGeoInfoLong = geoInfo.coordinate().longitude();
  }
  
  void GPShandler::start()
  {
      mGeo->startUpdates();
  }
  
  void GPShandler::stop()
  {
      mGeo->stopUpdates();
  }
  
  double GPShandler::Latitude()
  {
      return mGeoInfoLat;
  }
  
  double GPShandler::Longitude()
  {
      return mGeoInfoLong;
  }
  

  As you can see I have connected the signal postionUpdate() of QGeo class that I use for the positionUpdatedSlot() of the slot. I use the class as follows:

  Pop = new GPShandler (this);

  void::startTimer() {} App

  Pop-> start();

  }
  void::stopTimer() {} App

  Pop-> stop();

  }

  which are called when a key is pressed. However, the positionUpdatedSlot() of slot function is never called. I have debugged in my code and cannot find the problem. I can confirm the work of connection (function returns true), and that presented startup and shutdown functions are called as expected. Is there a reason why my slot machine function is not called?

  Note: I have another implementation of signal/slot in this app:

  Connect (mTimer, SIGNAL (timeout ()), this, SLOT (update ()));

  and it works very well.

  Thank you

  Gerry

  I do not know which of the following has solved my problem, but in any case, it's working now after doing these things:

  1. give permission to app to device identification information. (I had already given GPS, but examples also being device identifying information I thought I'd try that)

  2. remove the line:

         mGeo>setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods);
  

  as an example, I created using this example: http://blackberry.github.com/Cascades-Samples/geo-locationdiagnostics.html did not have this line

• Error: 200279. Problems with playback of three signals with NI 9234

  I try to read three signals at the same time with the NI 9234. But I have the problem with the buffer, I have read about this error and tried all the solution they gave (sample of Crescent by channel, increasing the number of samples per channel or decrease rate) but still nothing. I also try architecture design of producer/consumer model, but nothing, it always get this error. Someone knows how to fix this?

• [FPGA] Problem with the sinusoidal signal generator

  Hello!

  At first I want to apologize for my English is not my mother tongue.

  Hardware and software I use is:

  LabVIEW 8.5

  NEITHER RIO 2.4.1

  NEITHER cRIO-9014 (controller in time real CompactRIO)

  NEITHER cRIO-9104 (chassis and FPGA)

  NEITHER 9264 (16 channels, +-10V, 16-bit voltage analogue output Module)

  I made a very simple FPGA VI: a while loop, generator of sinusoidal signal and a FPGA of e/s node in the loop. I've specified the Gnerator settings by following the path:

  Frequency = 50 Hz
  Amplitude = 1
  Phase shift = 0.00
  Size of the table look-up = 1024
  = 16-bit amplitude resolution

  FPGA clock frequency (40 MHz)

  But the wave of "sine" I got is not what I wanted to get. First of all, its amplitude is 1 V. shouldn't it be coded on 16 bits? If I wanted to get 1V I should have specified Amplitude as a 3277. In addition, 'sine' is not very detailed, it's look like "steps", as many samples vere missing. What I did wrong? I checked the samples and tutorials, I did everything the same way. A I forgot something or not has not specify other parameters?

  Thanks a lot for your help!

  OK, I solved a problem. It's embarrassing to admit, but maybe this will help someone else I blame my inexperience

  The main solution to the problem was changing calibration of calibrated RAW Mode. After that, everythoing works as expected. I had a problem with a sample because I was using a multiplier to control the generated sine wave amplitude. But... She was set to 1 in the sinusoidal signal generator. That was the reason for waveform Gradin. Please, don't laugh too much

  In any case, thank you for an answer! It is now resolved

• Problem with PCI-e slots on the S51200ZCTO Pavilion

  Hello.  I bought this computer for use as a media server, replacing a 3300Z failed two weeks ago.  One of its functions is my AV receiver Rs232 command  I bought an adapter cheap PCI-e series online and installed.  The machine refused to start with the card installed in one of the three locations.  Attached to the HP splash screen.  Decided that my card 12 was obvious junk, I went downtown and bought another card for $30.  Same question.

  What I did:

  Disabled all 3 PCIe x 1 slots and slot of the minimap.

  The machine will start with the card installed, but of course, it's kind of useless.

  I activated the slots selectively.

  The machine will fail to start whenever the first location is enabled and one of the two cards is installled.

  If the first location is disabled, I can activate only two and three slots and the machine starts correctly with each installed card.

  I installed each card in turn in slot 2 and enabled only the slot 2 in the bios.

  Windows 7 can not find two cards.

  I manually installed each card in turn.

  They have installed but shows an error code 10 (device cannot be started)

  I have about confcluded that there must be a motherboard problem.

  I am a very technical user.  I have been upgraded and now my own machines for about 25 years and I've never met this kind of problem with a simple installation device PnP.

  If anyone has any idea I will try it.  I'm not enjoying the thought of working my way through levels of support for HP to convince them that there is a real problem or to ship the computer for repairs.

  Thanks for the chipset, here is another card:
