• 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 pictures from different files in the order in which I've rearranged?

  I moved pictures of several different files in a new folder.  How to save the in the new order, that I want what they?  They keep returning to their numerical order.

  The contents of the file can only be sorted by name, date of creation, file type or file size.  To put them in order, you need that you probably need to rename them.  Try adding 01 at the beginning of the name of the first file, 02 for the second, etc.   (If you have more than 100 then use 001, 002)

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• save data in binary file

  Hello

  I have 700 2D double table to save and I would save in 700 different .dat extension (binary) files. I know that I can save a table in a binary format, but using a dialog box that opens a window so that I can choose the file. Since there are 700 table I don't want to have to choose the right way every time.

  I use a dialog box create a folder where I want to save 700 files. For now I earn 700 tables in the text file of 700 different using the "write to the spreadsheet file" VI and I works well, but it creates text files...

  Is it possible to do the same thing but by memorizing the data in the binary file and without using a bow of dialogue for each file?

  Thanks in advance

• How to move data from flat file to the repository of execution

  Hi all
  
  We have 2 instances
  
  1. development - we are able to move the data from flat file to target the DB using scenario1.
  
  The files are in 04 who's ODI installation box
  
  
  2. enforcement Repo
  
  to scenario1 execution repo installed in ODI 07 which is ODI installation box
  but not able to move the data from flat file to target DB.
  
  We get an error - file not found.
  
  File is located in the box 04.
  
  My question is that what is the best process to make scenario1 course migrated to work.
  
  Appreciate your help.

  I wanted to say that in view of the dev and prod in the Prod repository agent is not a good idea.

  Ideally, in repo Prod, you must have prod 07 agent.

  In Dev Repo, you shouldn't have dev 04 agent

• 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.
