• Is there a maximum size or the limit of text file during storage and data transfer?

  HI -.

  We used WriteExtFile and AppendExtFile to store data in a CSV text file in a data folder in the same location as the executable files of Authorware.

  WriteExtFile ("data\\"^"Variable_Names.txt", Survey_Variable_Names)

  AppendExtFile ("data\\Survey_DATA.txt", Survey_Data)

  As a general rule, we always put our executable files on the hard disk of the computer (c) due to some issues we had with an incompatible network drive in the past.  Have the files on the C: drive, eliminated any network problem.  Our data has accumulated would be always stored on the C: drive as well.

  Now, we need to store a backup copy of the data on a server, on the C: drive.

  My question is: is there is a maximum file size that can be "read in" and then "written" using Authorware?

  My thought was to use ReadExtFile to read the content of the 'Survey_DATA.txt' file and use WriteExtFile to write these same data on a drive on the network, by adding the date and time at the end of the name of the file as a backup file.

  I used this logic, which is working to write on the "P": network drive

  WriteExtFile ("P:\\Survey_Project\\BackupData\\DATA_BACKUP_"^Backup_Date^"_"^Backup_Time^".txt", Survey_Backup_Data)

  Of course, the size of the original text on the C: drive file will continue to grow because "AppendExtFile" is used to add the data of every investigation file in the data file (CSV, each record on its own line).  If the size of the file we will read again (ReadExtFile) will also continue to grow.

  Is there a limit to what we can read in and then write back?

  Thank you!

  My apologies, it has been a few years...

  CopyFile is a function that you can load the WinAPI.u32

  Once loaded, use it like this

  Success: = CopyFile (FileLocation ^ "Sourcefile.txt",)

  Destination ^ "DestinationFilename.txt") "

  Remember that you must include WinAPI.u32 with your packed files.

• My WD drive bowed and data transfer is now very slow

  My WD drive fell to the floor once and now when I copy data from the PC to the hard drive, it is very very slow, it gives a minute to copy a file, then 30 minutes then again 40 sec and then another 5 minutes.

  In addition to the guidance of the spirit, I would say that you should not use the disc for something important until you sort.

• PXI data transfer between OTN and FPGA

  Hello

  I have a DAQ card in my PXI and a FPGA 7813R map.

  The problem is that I send sample waaveforms of the data acquisition card to the FPGA card (which only has digital i/o) to launch my control on the FPGA. When I generate a sine wave of 50 Hz in the OTR to simulate a measured signal and send it to the FPGA through the controls in the Panel before (http://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgaconcepts/pfi_data_transfer/) the signal happens on the fpga is much slower than 50 Hz indicating this folding is (it takes too much time to send the data). I tried to use this method of data transfer because my control requires only the more recent data, but it also has a phase lock loop that requires the data arriving at least resemble the original signal. Another criterion is that the control to data more up-to-date as possible. I know there is another option of the use of DMA FIFO, but I use it because I thought it would take more time to send the data, because each value must be sent.

  My questions are:

  I go about it the correct way? I know that there is the FPGA cards with analog inputs. I buy one it is because I have a large amount of differential analog inputs (20 +)

  Is there a quick way to transfer data to the FPGA. (I have converted all the FXP data before writing to the FPGA)

  Hi Jagwa,

  You should not have to synchronize the RTOS loop that written information and the FPGA VI which is read.  Instead, you can simply use a FIFO.  In RT, you can write all the data points for the FIFO, and then you can extract them one at a time on the FPGA VI and use them as needed to control functions.  In this way, the only time you need to worry about stopwatch the FPGA VI to get out the data to mimic 50 Hz.

  Kind regards

• FPGA block memory and Timing FIFO

  Hello

  I am trying to access the data of the memory block and a FIFO, both having an equal number of elements.

  I'm trying to access the data must be coordinated with the waveform of a block of Xilinx, I use to deal with the elements of the FIFO and the memory block.

  My block of Xilinx has a 3 clock offset cycle and one without a clock cycle lag, which can lead to my use of knots of late.
  My question is, the output of an element of a FIFO occur in a clock or a clock set cycle? Also, I am aware that there is a delay of the output clock cycle
  block of memory to hold data into account initial reading, which will lead to my choice of offset of 3 clock cycle. Just a handful to decide how much to delay the nodes to use.

  See you soon

  Hi RichieA

  If the function or if it is a FIFO, or a memory block is inside the recycled then timed loop function and of all that is on the inside must be executed in a heartbeat. Don't forget that when you compile you are actually programming and connect a gate array so when the compiler is running, it will try to create the FIFO or memory to be executed on a tick. If this is not possible, you should get an error in NI LabVIEW or in the compilation process. Here is a link with more information.

• FPGA: Vs timed loop Timer?

  Hello

  I would like to create a FPGA loop that runs at a fixed rate. Whatever if I use a timed loop structure or a timer loop express VI into a regular while loop? Under what circumstances should I choose one over the other?

  I understand that the timer loop approach can cause the code in the loop run twice before calendar is established (but this isn't a problem for me here). Are there other differences in the two approaches?

  Thanks in advance.

  JKSH wrote:

  But my question was about the differences between the use of "multi-cycle" Timed loops and VI express loop timer.

  In a targeted FPGA VI, all call loops are single cycle timed loops (SCTL).  This means that all the code in a SCTL must run in a clock cycle, so there are a few types of nodes cannot be used in such a loop.  In a used while loop with a timer, you can use a wider range of features, but the loop will generally run much more slowly.

• Slow data transfer between computer and HP Laser Jet 1320n

  I recently bought a laptop with windows 8.1 and successfully connected to 1320n times via LAN and wireless networks. Problem is when I try to print .pdf files, data transfer from my computer to the printer seems very slow and that's why it takes several minutes to print 10 pages. On the print window of my system, it tells me the data to transfer a file from pdf page 14 are about 75 MB.

  My questions are:

  1-is-normal this size of data?

  2. What can I do to increase the transfer speed?

  Thank you in advance.

  H.A.

  Thank you very much for the reply.

  I hae has solved the problem by installing the drivers that are on the product page (I was using the Windows drivers when I had the problem). Everything works as it should now.

• Card FPGA and data acquisition synchronization

  Hi, we are control and data acquisition of several hardware devices (including Photodetectors and translational stages). Until last week, we used all the controls and acquisition using a PCIe-7852R FPGA board. However, we decided to move the acquisition part to a PCIe 6363 DAQ card to improve the sharpness of the tension. During the test, I found that the internal clocks in the FPGA and the DAQ cards are slightly inconsistent (not just a phase delay, but a difference in the period).

  I know because I have generated a square wave (period = 20) using the FPGA and gains using the data acquisition card (at a rate of 200 kHz, that is, 1 taste every 5). I have observed acquired place shifts 5 every 5 seconds approximately. Such a change does not occur if the production and acquisition is done using the same Board. Therefore, the only explanation is that the data acquisition and FPGA cards clock frequencies are different. According to my calculations, the percentage difference between their time clock must be 5/5 s = 0.0001%.

  Therefore, I wonder if there is anyway to synchronize clocks between them. Or, is it possible that I can drive the FPGA clock-based DAQ hardware, or vice versa? Also, please let me know if there is something trivial as I fix.

  Thank you very much.

  Kind regards

  Hi Varun,

  my post was only one solution...

  Your data acquisition card may take an entry to control sampling of trigger. In this mode, samples draw on a rising edge of the external clock signal. As long as you stay within the limits of the DAQ (100 MHz for your card) material sampling works perfectly. There are even examples coming with LabVIEW explaining how to program your data acquisition card...

  This mode use you your FPGA as clock source sampling for data acquisition. Both will run on the FPGA clock in sync. When the FPGA is a bit out of 40 MHz, so it won't matter because both devices are triggered on the same clock signal...

• I need to use programming like ActionScript loop, trigger, and load the data in the movies.  I can do with AE?

  I have been producing auto generate and parameter based animations for an artist over the years using Flash.

  Like this: Zarah Hussain | Animation

  Someone asks now that we use After Effects, but I need to use programming like ActionScript loop, trigger and load data into the movies.

  I can do with AE?  We need the loading animation 3 data values that affect the colors in real time

  Is it: -.

  Flash = online and interactive

  AR = fixed and linear.

  Help!

  You cannot use AE for this kind of things. Outside very limited real-time EI functionality it has not yet officially a dynamic performance of preload beyond the evalFile() hack. None of this makes no sense at all.

  If you have any scripts or tools that analyze currently based on the name of the Cluster, it could be affected.

• RT PXI, ethernet data transfer

  I have a simple question, I just have to transfer data from my RT PXI system and get to my PC. That's all - I used the following code. Just by using this code, 50% of the resources are taken. Then I used shared variables to transfer dynamic data fromt channels (another question mark? if I have to do this) the system gives jittering... the trasfer is falling apart... After using 3 shared variables (published network) the system loses contact with the PXI as 100% CPU power is used in place... What is this RT PXI system? Need help

  I have also used method TCP IP... an exaple... can not transfer more than one channel... can someone send me or tell me what is the best method... want to see is the unit I tested is what gives an output or not go to a remote place... in the same network... at least in the same room and it connected directly to my PC now.

  Hi mbhatti2000,

  as I told you before: it's not maky any sense by using a loop timed in this example!

  Use a non timed loop instead, the timing will be done implicitly by the acquisition rate and configure the samples to read you.

  Before you start programming you become familiar with the principles of database aquisiton and real-time programming, you will find some useful links at the bottom of this thread. Have also a look at the examples that come with LabVIEW, there are also many examples to be found online.

  The screenshot below shows you a very basic example of continuous data acquisition where a shared variable is used to transfer data to the host.

  Also I would ask you to post your real code, as the screenshots do provide all of the necessary information.

• Time and date of the Iphone 6s set contacts automatically / backup

  Hi my name is Rebecca. Please be patient, this is a long story with a question to which Apple for a month and a half has not been able to solve. The end of February, I went to Sprint to upgrade my iphone 6 to a 6 s. (my 6 had no problem). The backup and restore to the other went off without a hitch. Two weeks having the phone, date and the value automatically switched to a GMT setting which is 4 hours ahead of New York. Assumption is that the phone has been deserted. I got a new phone and everything has been backed up and restored again. Less than two weeks later, the same goes for the 2nd iphone 6 s.  I went to Sprint and got a 3rd iphone 6 s. backup and restored all again. Less than a week later for the 4th time, the new iphone 6 s time and date switched to the time zone GMT 4 hours ahead of New York. At this point, I called Apple Tech support. A very nice tech Jason worked with me for 2 weeks to fix this. He sent Apple a 4th iphone 6s. We did a backup and when the new phone came in did us a restore. A few days later, the same problem. Apple accuses Sprint, Sprint complaint to Apple. At this point, Sprint said that my sim card was corrupted and he sent me a new. On the phone with Jason, we did a reset of the iphone 6s failing manufacturers. Removed the corrupted sim card and put in a new vacuum. Phone restarts and when you get to the Setup screen, it asks "set up as a new user or a user to return. Jason said as a new user.  I clicked on new user. Following her request for an apple ID. Jason said I should put in my existing apple id (although it has been activated on as a new user). At this point the phone wouldn't turn on. On the phone with Sprint. They did not understand as to why the phone would not activate. Jason suggested that I put my original sim card in (which was noted as corrupted), then the active phone. At this stage because I had not done a restore, the only information on my phone now an old backup who had my contacts and some of the notes, images etc. Jason said to do a restore after just 24 hours to be sure of the time and the date stay correct. Not happened. Less than 24 hours, the date and time that is set to automatic changed to the GMT time zone. Jason was out of suggestions. We left him there. I am very angry to pay more than $800 for an iphone that feature very very important does not work. On mine, I restored my phone and thought what I'd do. I then did a backup. I'll stop my icloud. I have reset my builders phone by default and when I went through the whole upward I plugged my phone in itunes and restored my phone from my computer backup. (Icloud is always OFF). Less than 24 hours later at the date and time in GMT area again. Once again, that I have a phone very very expensive with a feature that is vital for me, I can't use. Yes, I could turn the machine off, but I shouldn't do that. So here's my question: Iphone 6, I have not had any problems with my icloud or my sim card or the date and time. 6 s IPhone that I do. I got iphone 4 brand new 6s with the same problem. Is - that my sim card is corrupt and transfer information corrupt, though only it worked fine in my iphone 6? Second question: I don't want to sign up for a new apple id and start from scratch. This will screw up my gmail which is linked to the apple ID. How can I back up my contacts only on my computer and then be able to reset my phone manufacturers by default, then erase all information from my existing apple ID in order to use again, but only restore contacts which is the worst part of transfer phones. Apps and notes, photos and all the rest is not a problem to start from scratch, but contact is almost impossible to have to type each hand one by one. Please someone out there with a solution. Thank you in advance.

  Two recommendations.

  1 post this issue on your part on the iphone forum, to confirm the number two with someone else.

  Use iPhone

  2. you must stop working with Apple. Your iPhone download the signal giving them news of the time and origin of this signal
