• How to compress the data in binary file?

  See some games compressed into bin files and a program to extract these files, I don't know how to compress the game binary form files. I'm not a programmer not so no knowledge of coding, if you can tell me a software suitable for this sick work be grateful.

  I want to compress my games strongly and I noticed this binary format a high compression rate, so I want to compress my files in binary format using a program and extract them easily when necessary.

  Hello

  It doesn't really matter for good compression which is the output format, what matters is the method of compression used to compress.

  I tried some of them and the best compression I've seen is called LZMA2, it practically reduces a file size at least 10 times.

  What you can do to use this compression method is to download and install 7zip free http://www.7-zip.org/

  try to compress the original file (use to create the binary file with the extension BIN) with LZMA2 METHOD ULTRA (it's what we call in 7zip) and then compare the output with the binary size and you should see it is almost the same if they aren't better...

  How ever compression takes awhile.

  That depends on your definition of 'easy '...

  The HTML5 File interface can be used to access date in browsers supportthe file was last modified.

  1. Add a hidden page that contains the file download point (P6_FILE_DATE in this example).

  2. create a dynamic action of change on the file upload question (P6_FILE):

  Event: Change

  Selection type: Agenda

  Region:

  Real Actions

  Action: Run the JavaScript Code

  Fire on Page load: NO.

  Code

  console.log('Get file modification date:')
  var fileItem = $x('P6_FILE');
  if (window.File) {
    if (fileItem.files.length > 0) {
      var file = fileItem.files[0];
      if (typeof file.lastModifiedDate !== 'undefined') {
        console.log('...lastModifiedDate for file \"' + file.name + '\": ' + file.lastModifiedDate);
        apex.item('P6_FILE_DATE').setValue(file.lastModifiedDate);
      }
      else {
        console.log('...browser does not support the HTML5 File lastModifiedDate property.');
      }
    }
  }
  else {
    console.log('...browser does not support the HTML5 File interface.');
  }
  

  If the browser has support for the File interface and lastModifiedDate property, the date, the file was last modified will be presented in the P6_FILE_DATE article in the form:

• 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.

• Help! Trying to write an array to a file without having to rewrite the old data each time.

  Hey everybody,

  I have a vi that takes a 2D array and writes to an xml file. The purpose for this is to characterize the pathloss through a matrix dowkey 10 x 10 to different frequencies. I use this program to create a table of correspondence for the switching matrix, so when I make one of my tests I can get an accurate measurment. The problem with this is that I take data points about 299 by combination of matrix switches leading me to data more than 32000 points in the lookup table. I use xml because each data point requires a header so I can analyze via the table of correspondence with another of my vi when I need that pathloss. What I'm trying to fix, is that when my vi wrote in a file at a time to save memory space, he wrote a single Bay. When writing, it rewrites the old data, and then the new data. As the number of points of data increase so does the time of latency of writing in the file. At the time wherever I am finished, it takes about five hours to completely write to the file. Does anyone know how to write about writing to a file without having to rewrite all the old data? Attached, it's my vi to write to the file, my vi for research in the file and an example of one of my tables in research.

  Thank you

In the file I would write are values of x and y of my points of data in two columns, however, the data is in a table and the data of x consists of 3 pieces of information: an initial x, x incremented value and the number of points in my sample of data. How would I go about this?

  The number of points is redundant, because it will be the same as the 'other' in the table.

• Writing data to the file when the trigger is activated?

  Hi all

  I'm quite new in lab mode, and I find it difficult to find a solution to this problem quite simple. I installed a gauge on a tank, and each time, he reached the limit of overflow of the VI should write all data to a file. I implemented my data tables, but I am struggling to find a way to have the VI writing the data when the specific trigger (the tank overflow) occurs. I'm sure the solution is quite simple, but was faced with this during a few days now so I decided to ask for help.

• How can I write snapshot of my data to the file measured every 5 seconds

  Hello

  I try to take a snapshot of my stream once every 5 seconds and write it to a. File LVM. I have problems with the VI "write to a measurement file. The pace at which it writes data to the file seems to be dictated by the 'Samples to Read' parameter in the DAQ assistant. I tried placing the VI 'Write in a file measure' within a business structure and the launch of the structure to deal with a "time up" VI. As a result only in a delay of 5 seconds before the insiders 'Write in a file as' VI. Once the VI 'Write in a file as' is launched, it starts writing at 20 x per second. Is there a way to change it or dictate how fast the exicutes VI 'Write in a file measure'?

  My reason for slowing down the write speed are, 1) reduce space occupied by my data file. (2) reduce the cycles of CPU use and disk access.

  The reason why I can't increase the value of 'Samples to Read' in the DAQ Assistant (to match my requirement to write data), it's that my VI will start to Miss events and triggers.

  I don't know I can't be the only person who needs high-frequency data acquisition and low-frequency writing data on the disk? However, I see a straight road to key in before that.

  The equipment I use is a NI USB DAQ 6008, data acquisition analog voltage to 100 Hz.
