• "Waiting for in time (RT PXI target) real answer" error when the program is waiting interruptions

  Hello

  I developed an application to detect interruptions generated by an electronic card and act accordingly. The program was developed in labview, but she calls a dll; created with labwindows. The dll is scheduled to open the visa communication, select the events and install the interrupt handler and when an interruption is detected, it reads the value of the different registers of the map and returns to labview to view.

  The problem is that when the program expects an interruption, a prompt appears with the message "Waiting for real-time (RT PXI target) real answer" and the only option I have is to click on the button to disconnect the pxi or just wait. If I wait and I generate an interrupt, the prompt disappears and the application view data as it was planned.

  To wait for the following code the interruption has been programmed into the function:

  While (flag == 0)

  {

  Sleep (1000);

  }

  When an interruption occurs, the value of flag set to 1 and function continues without any problem. I am not really sure, but here is probably the problem and it probably isn't the best way to wait for a break because the sleep function suspends the thread to the configured time, but at least the load calculation in the PXI is between 0 and 1%. I was wondering if anyone knows how to wait for a break without 'lost' communication with PXI and if there is a better way to do it.

  Any response will be welcome and thank you for them,

  Hey there.

  You see problems with connectivity it's because the thread by DEFAULT CallLibrary nodes running in is the UI (UI) thread - UI thread manages also the important things like, say, communications (especially all the connections for the VI server) and other things that you could run all the time.  A CallLibraryNode is not, by default, intended to be used to execute code that runs for a long period of time.  If you want to do this, you assign the execution of the CallLibrary node to run in the context of a LabVIEW run-time engine thread (by selecting to make it work "in any thread") and not the UI thread.  This can be done through the properties of the CallLibraryNode.  By selecting "run in any thread" the call DLL will be generally in the context of the thread running in the run LabVIEW, which is usually what is meant when even.  The VI CallLibraryNode color change of Orange (UI) to blue (LabVIEW thread) so that you can quickly tell what context the appeal will be in.

  The reason the interface thread user is the default thread is because most often DLLS calls need to be serialized (because of functions is not not thread-safe) and so it serves to protect the integrity of the system.  However, if you know your threads are thread-safe, or you will use these threads for a while, it is best to program the CallLibraryNode to use a Thread of LabVIEW execution rather than the UI thread.

• Waiting for data on serial port

  Hello everyone.

  I'm trying to figure out how I can solve a problem on LabView. I programmed an Arduino board to read and send a data table of the accelerometer on the serial port. I want to LabView to receive the data and graphs it. My problem is that Arduino send data on an ongoing basis and sometimes LabView can not cope with traffic and read some values "0".

  Is it possible to wait for the data and solve this problem?

  I joined my current vi.

  Thank you much in advance.

  Yes, the characters are 0-9 and - no. ' + 'or'. '. And bytes that vary.

  Once again, thank you very much.

  Given that you send ASCII characters, change your Arduino code to send a character to end of line (10 byte value) at the end of each transmission.  Your code is already configured to use it.  Then you need not use the bytes to the Port at all.  Suffice to say the VISA of reading to read a large number of bytes.  Playback stops when it finds the stop character (value 10).  Your code will get a lot easier from there.

• Start stuck on "Please wait for the Local Session Manager."

  I would say that this problem started a couple of days. Went to start my laptop (Toshiba) and he sat on the "Please wait" message forever.

  Had no problems to start in safe mode. Looked up various ways of addressing the problem.

  Was able to change the resume date and back a few weeks ago. Still no luck. Happened to read something on a printer Epson being perhaps the problem driver (it was installed a day before the date of restoration chosen). Uninstalled the drivers, computer still does not start.

  Tried restarting running. I do not have the CD it came with Vista, but it was an option when you hold F8 during startup (I think?) Couldn't find any problems.

  Ran check on memory. No problem either.

  Changed settings for a verbose startup and ran a Diagnostic startup - all good for this. Then tried selective startup load system services... This is when the error occurs. When starting, it hangs on "Please wait for the Local Session Manager" and does nothing more.

  I looked in the event viewer to see what came that time and a couple mistakes were:

  Event ID 6000: winlogon notification subscriber was unavailable to handle a notification event.

  Event ID 7026: the next (s) start or start failed to load system
  spldr
  Wanarpv6

  It would be very useful for me not having to run my computer in safe mode automatically all the time, although it is useful that I at least have that option. Any help is greatly appreciated.

  Hello

  1. by chance your computer is connected to a domain environment?

  2. as you mentioned in your article that you tried the selective startup, I want to confirm if you have disabled the services left 3rd after hide Microsoft services?

  If you did not disable these services make sure you disable and then check if it works.
  See the article below for more information.

• Waiting for CPU: what exactly does that mean?

  Hi all
  
  I worked on this database (11.2.0.3 on AIX 6.1) try to improve the performance of certain lots of an ERP system developed by my company. These are all processes that work very well in other environments, but here the clock times are horrible for the load and I was seeing 10% CPU, 90% CPU waiting for almost every process. This is the last section of a very long trace file where you can see the invisible "wait."
  
  I know not how to do this: if I run something in the OS with a higher priority than to Oracle, what I will get. "Lack of processor" according to me, is the name for it. My question is: what else can cause this? If the OS say that nothing was on the computer, how can I study the root cause?

  Your trace file contains 25 million lines, that is a significant amount of write operations, to be compared with the information that reads one-piece 620K consume dry 4858.
  It is necessary to note that writing in the trace file leads to loss of time only when it is caused between measure of elapsed time from a visit to the database. But even if the write operation is due to the outside to measure the time of the call for a database (for example, information about a call, as FETCH #) it can be inside some call parent and will be included in the duration of the call of the mother.
  If you are interested in the details of this process, I prepare an article on this topic in my blog.

  I would therefore recommend to reproduce a similar load without follow-up.

• Stuck "waiting for the printer to be available."

  After initially looking at it's going to print, the printer dialog box displays "waiting for printer to be available" and it's there (even if the printer - inkjet HP series C3800 - is ready).

  Here is what I tried:

  Using the HP utility software on the same computer, I am able to successfully print a test page, which rules out a problem with the printer and its connection to the computer.

  Printing worked normally before moving on to the Sierra. I tried resetting the printing system and add new printer (Sierra recognizes very well). I also tried to run in case disk utility have a permissions problem.

  I'm stumped at this point. Help much appreciated.

• Hi8 thru cam HDV into FCP 7: waiting for timecode

  Hello

  I have a bunch of Hi8 tapes I want to capture on the drive by running through Sony CCD-TR400 on the Canon HV - 20 MBPro & FCP 7.

  I can see the execution in the window capture, but when I hit capture now it gets no further than "Waiting for time code."

  I guess the Hi8 analog, but hoped the Canon with its AV > DV option would treat his way through.

  Any ideas?

  Is the only way to do this would save on tape dv on Canon HV-20 and then capture the disk?

  The best

  Elmer

  Hi8 uses only consumer re-writable (CCFC) timecode that is not readable by the PCF.  In the FCP capture settings, set "Device Control" device not controllable and then use Capture now capture rather than in batches.

• "waiting for encrypted google" does not allow me to open a Web site

  When I try to open lifenews.com, which I visited many times, there is a message saying left down "waiting for encrypted google." I don't even use google chrome? I don't know where to go to get rid of it, I don't want nothing blocked unless I specifically ask to be blocked. I did the research, said it's a blur, said another security settings to uncheck the ssl2 and ssl3. Nothing works. Can someone tell me please how to remove this thing waiting for encrypted google.

  You said blur, which is an add-on. Use the blur, or any extension of similar content filtering? If you think one of them might be the problem, you can test Firefox Safe mode. It is a standard diagnostic tool to disable extensions, hardware acceleration, and a few other advanced features of Firefox.

  Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Any improvement?

• Extend my extreme network with another extreme - waiting for internet access

  Hello - I have a new generation Airport Extreme (let's call it Extreme1) connected to a Comcast modem and it works very well. The extreme will be the router that the modem has no router function. I'm trying to expand my network to another room with another extreme (let's call it Extreme2). I have a connection cable between two rooms. Extreme1 has an ethernet cable from one of its LAN ports connected on port WAN Extreme2. When I try to create a new network with Extreme2 (in aid of the same name, passwords, etc.) it does not work. He was suspended at the end when he is looking for a connection ("Waiting for internet access")-I did the following things based on what I read here:

  1. Changed IPv6 link local parameters
  2. Tried the whole upward on my Macbook and tried on my iphone
  3. The Wan first and then tried to change the configuration after you done for Extreme2 by creating a network
  4. Tried to create a network with Extreme2 connected directly to the modem
  5. Extreme2 factory reset after every attepmt

  And nothing works. Kicker is, I also have a reasonably new airport express and the same thing happens to her as well.

  Do I need to adjust some parameters of network that I'm not aware of? Is it possible that my LAN ports are disabled on Extreme2? It is brand new.

  Thanks for any help.

  Have you used the Apple Setup Assistant?  If you did, it had notified you that the extreme second was being configured "add using Ethernet. The wizard will automatically configure the second airport with the appropriate settings for you.  All you have to do is enter a name of device for the second AirPort Extreme.

  Here I'm assuming that you reset the second extreme to parameters by default until you set it up again and that your second Extreme is the current version of the "tower" or that of previous versions "flat or square.

  The example below shows an AirPort Express as the device which is the extension of the network, but you will see the name of your network and AirPort Extreme on your configuration screen.

  Post back if you need some tips on using the "Wizard" for your configuration.
