• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• How to save data quickly to the high sampling frequency

  Hi all

  I use a structure of producers and customers to measure and record the data. The sampling rate must be as high as 10 kHz. Given that so much data, it takes a long time before the data is saved. At first, I saved the data in an excel sheet. Then I tried to save it in binary, but it still takes a while to complete save. How can I make the time savings a short circuit?

  Thank you

  The best

  First we will make some corrections to your DAQmx code.  Since you are using continuous sampling, do NOT connect the samples per channel.  Which is actually limiting your buffer.  And there is really no need to define your buffer size either.  It is default to very big, so this isn't a problem as long as you read your data quite often.

  Now your data connection... You simply create a very wide range while acquiring data.  Then, you save the data.  It's actually not through the advantage of using the producer and the consumer.  You should save your data in the loop of the consumer.  It will be elinate need a lot of memory and you save the data to the file while you are buying.

  But, in this case, I say that the producer and the consumer is not even necessary.  Use the DAQmx Configure registration VI.  With this VI, you can tell DAQmx to disseminate all data directly in a PDM file.  You don't have to do anything.  It is by far the best way to save on your DAQ data.

• How to save data in the spred sheet file that is?

  Hello

  I want to save a table in the same spred sheet file I read my external device.

  here as an attachment, I enclose the vi.

  This is the example of data I want to save for example in the first column I want only numbers with no floating point.

  and remaining column is everdata, it should be the same.

  As an attachment, file name 11 is the same file that I want to, but I always get as file attachment 2,

  can you please guide me how can I get data that is displayed in the table of labview.

  Thank you much in advance.

  This code - using the Format to a string - creates a very similar to the log file output 11. You can write the string to a file with write a text file or write the string array with write to File.vi of the worksheet.  Write to File.vi of the worksheet internally converts an array of strings for what is in the string, and then wrote this text, so it makes more sense to use only write to text file. Write to Spreadsheet File.vi help will make additional copies of the data, which can become a problem if the dataset is large.

  Read the detailed help for Format string for more information on the available format codes.

• How to save data to excel, word, etc.

  I want to use the entry in the spreadsheet, but the format of the saved data cannot be opened directly in excel or word. Can I still use write on the worksheet or that I have to use other buttons. In fact, I don't know how to choose the format of the recorded data. Thanks for responding.

  ADrexelDragon wrote:

  The format of the Vi called write in spreadsheet records directly in a xls file.

  Not exactly. It stores data in an ASCII ' Tab/return' file (assuming that you do not change the separator). Means that the file can be opened by any text editor. Including Word and Excel.

  If you want to open the file directly with Excel (or Word) with a simple double click, then simply add .xls (or .doc) as the file name extension.

  If you use the .txt extension, there are chances that your case will be opened by Notepad.

  Nothing complicated!

• How to save data in labview 2009

  I need a botton or a way of access to record data. What I've done, is that it can record data, but each time after I execution of the program, it ejects a dialog box to save the data. What I want to do is using a botton that I can record data only if I want to save it. Meanwhile, in this program, I have to assign a path before you run if I want to save the data. Please answer this question for me.

  You really need to spend time first with the basic tutorials.

  Drop a while loop on a diagram. Place a case statement in the loop. Place a write to the spreadsheet within the real deal. Right-click on the terminal structure of the case selector (the '?'), and then select Create > control. Right-click on the terminal conditional lease and select Create from the loop > control.

  

• How to save data from the RT at base of remote Citadel using Citadel api writing

  I try to get a target RT to launch a VI when it is started, which acquires the data and sends them to a database of Citadel on a networked computer.

  I'm doing it with the Citadel write API, more precisely the functions in the DSC module; Open the trace and write trace close path.

  I have a project with the added goal of RT. I have a simple VI under job-generating data and sending it to the local database of the Citadel. This VI works very well and the data is written to the database. However, I have a similar VI under the RT target but open VI track is broken and the VI will not run. It seems that one of the subVIs in Open Trace VI is broken and will not run.

  I'm missing something here. Can someone help me understand this?

  The VI is probably not compatible with real-time, perhaps she calls a DLL or something. What you need to transfer data from RT on a Windows host computer and let that host the insertion in the Citadel.

• How to save data to the SAP database?

  Can someone tell me please how to warn of data to SAP databases?

  Thank you

  Hi AEK.

  Take a look at OSS 105047 - Support for Oracle in the SAP environment functions that you will find this under

  14

  Oracle Data Guard

  You can use "physical Standby". You cannot use "logical Standby". You are allowed to use Fast-Start Failover (FSFO) but the SAP is not supported. You can use Data Guard Broker. You can use the Maximum Performance Mode, maximum availability Mode and Mode of Maximum Protection. In the case of maximum availability and maximum Protection, you must pay attention to a fast in order to avoid network connection performance problems. Maximum protection causes the primary database to terminate in the event of problems in the database pending.

  And you will find the 2010 http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf Oracle white paper

• How to save data in mode 4 bits instead of U8

  Hello

  I use LabVIEW to acquire and record data through the meter timer PCI6602.

  My signals is really low while data can be expressed in 4-bit (0-15).

  I used the conversion in U8 and write using "write binary files.

  If it uses 1 byte for each data point, but I would like to reduce it to 4 bits (half bytes) for each data point.

  Can someone help me with this?

  I enclose my program for reference

  Hi TonP,

  at least on my computer with LV7 multiplying by 16 is faster than rotation of 4 bits
