• How to save the data of different rates in a single VI?

  Hello

  I tried to acquire 2-channel measurement of voltage at 10 kHz and analyze data, finally to save the data to both 1 kHz and 1 Hz. What I did is this loop of producer/consumer use to do the work of recording at different rates. I have queued all the data in the main loop, and then removed the data and write it to the file in other loops. I added "wait = 1 ms' a consumer loop for recording data at 1 kHz (loop of fast logging) and added" wait = 1000ms' in another loop to get the slow 1 Hz (logging loop) data record.

  My problem is that the data record works fine in the case of 1 Hz, but it does not work for the case of 1 kHz. Although the time-out period defined as 1ms, the interval between two samples in the loop of fast data recording is about 100ms.  Subsequently, 1ms, 10ms, 100ms, 150ms tried in this loop to see what intervals are in these cases. I found that the intervals are same as assigned in the timeout greater than 100 ms, but if the time-out is set to 1ms or 10ms, the intervals are again around 100ms.

  My question is - why I can't reach data record 1 kHz using loop of consumers/producers, while the same way works for the case of 1 Hz?

  Thank you very much

  You are sampling at 10 kHz and you want to back up your data "as if you sampled at 1 kHz and 1 Hz", if I understand correctly.  I also understand that you use the design of producer/consumer model to help with this (a good idea).

  I'm assuming that the producer 'product' a segment of data at a time, to say the value of a second of data or a 2 x 10000 I16 (assuming a 16-bit integer A/D) table you put into a queue and wait for the consumer.

  If you have data at 10 kHz, how do you get representations to 1 kHz or 1 Hz?  There are (at least) two possibilities - average data over the interval of proper time, or (re) sample data.  The good thing is that you can handle the situation 1 kHz and 1 Hz, essentially at the same time and in the same processing loop.  I'll discuss the case 1 kHz - with the assumptions I made, the case of 1 Hz becomes almost trivial.  I'll discuss treatment also just one channel, as it is similarly almost trivial to go from 1 to N-channel.

  If you have 1 second of data sampled at 10 kHz, and will "reduce" 1 second of data sampled at 1 kHz.  Note that you have 10 samples for each data point that you want in the end.  The "Averaging" method said "Replace all 10 points in the average of these 10 points", while "resampling" method said "replace 10 points with, say, the first point, ignoring the others.  An easy way to do this is to use the Reshape feature to transform an array of 10 x 1000 elements of your array of 10000 items 1-D 2D.  Now, you can use a loop FOR an average of 10 items or simply extract the first.  [This is where almost everyone, including me, a mistake - when you put a 10 x 1000 2D array in a loop, you get 10 iterations of 1000 items and we want 1000 iterations of 10 items.]  Oops, what to do?  [Simple - converts 2D array before sending in the loop FOR.]

  So when you have processed your 10,000 points and got both 1000 samples "1 kHz" and 1 "1 Hz" sample, you write each of them in their respective folder and wait for the next item in the queue of the consumer.  Consumer focus on the queue loop, it will automatically 'block', waiting for the producer of the 'feed' some data.  Note that the producer generates data once per second, producing 10000 points for the consumer in the process, but the time to deal with these points and perform the required disk i/o should take only a few milliseconds (certainly not more than 100, even if writing to a floppy!), so you don't have much time to do other interesting things (such as display data).

• What format should my files?

  before that I am committed to the purchase of this product, if I want to take a pre-existing song and break up into individual instruments so I can manipulate them (as in a remix of an existing song to store some items, but change or add others), what format should my file?  is it important?  Thanks in advance for any help you can offer me.

  I think I might have exaggerated what I really want to do. I want essentially to take existing songs and making them flow with the same beat that underlies each of them in a scope, a trail mix of several pieces. I know I should be able to adjust the tempo/BPM so that they are consistent, too, right?

  So, if you think I'm capable of doing these two things with hearing, is there a certain file format that would be better than another?

  Yes, you can do mixdowns which do quite easily - it is just a matter of butting places them on a track and adjusting how they go through. It is Visual and intuitive to do. And yes there are tools to change the speed of tracks, although it should be a little more careful with this, that the people are often very sensitive to changes in the titles they already know. The good news is that a lot of titles that are suitable for this kind of treatment are consistent in the choice of tempos, but with all these things, experiment a little will get you quite a long way.

  As for the formula that you save the results in - it's actually not really a problem if you stick to the default values. The principle is quite simple; you mix the results down to the internal format of the hearing which is uncompressed wav files. Having done this, you can make a distribution of copy as an MP3 player if you want to. The reason to do it like that, is that whenever you create an MP3 file, you will lose information - in order to become an MP3 of an MP3 file is usually pretty bad news. And this also has implications for the way in which you build your tracks in the first place - try to not start with MP3s, but good CD imported directly or whatever. If you want to start with vinyl, then save as files wav, for exactly the same reason. Bottom line is that MP3 is a distribution format and not a production one!

• Save the data to the excel file

  Hello

  I make a program reads the value of the probe via serial port... but I don't know how I can record this data in excel file... I open the example in the labview example, but I don't want to like this... becaue I use a while loop in my program that cause opened "multi" excel file... . How can I solve this problem?

  You need to think about what you want to do, not how you want to do.  I'll make a few assumptions here - adopt to your notebook loads "real."

  I guess you want to take a series of readings from a device (sensor, serial port).  I suppose you take multiple readings, perhaps their display on a table or chart, for a certain period of time.  Once you have a set of data, you want to save all the data in an Excel file.

  If this scenario is correct, there are three distinct phases to this task - implemented the data collection (open the serial port, manage the interactions of the user according to the needs), data collection (and potentially produce tables or graphs) and save the data.  Note that only step 2, collect data, involves a repetitive action appropriate for a while loop.  Once you have all the data, you can then open an Excel report, use something like Excel table easy to put the Table in the report or chart Excel easy to put a chart in the report and save the report in evidence, save the report.

  If you are using a relatively recent version of LabVIEW (2010 or later), the new generation Excel report screws are pretty easy to use.

• Save the data in a horizentall

  Hello

  Any that offered little help on how to save the data in a portrait. As a result of my attachment all my datas saved az a tables!

  And also, I'll be glad if you told me that I can add text in front of my data as an outamaticlly to explain?

  Any suggestions would be greatly appreciated! Thank you very much!

  Sincerely,

  First convert your string numbers using decimal channel number.  Once your numbers have the appearance of a string, you can format the text with them.  If finally, you can use concatenate strings to concatenate (add all channels) your number in the string with another text format:

  

  This code would create the following string:

  

  Then, you can save your all channels on a line using the same method as above.

• How to save the data in a form called?

  Hi all.

  I have two froms.like FORM A and FORM b.

  I have a button on the FORM B.

  When I click on this button, FORM B and FORM data should be store in the database...

  I wrote something like this in the form B

  when_button_pressed->

  commit_form;

  go_form ("c\user\babu\FORM A.fmx");

  commit;

  Here, my problem is when I click on save button only saved FORM B, FORM A not memorizing the data in the database.

  Please help me and tell me where the error...

  Post edited by: N.B.Babu

  I guess that the modules form a calls B with OPEN_FORM module (..., SESSION), IE. Module B works in the new session of database

  (by the way, the database connection is the same, because the connection to a database can go several database sessions).

  Your code cannot save the data in the two sessions of database:

  commit_form; -This saves the data only from module B (because A module work in diferent database session).

  go_form ("c\user\babu\FORM A.fmx");  -Now you in module A.

  commit; -This has no effect, you are now on the module to a.

  Kind regards

  If you burn to a DVD disc in first items 10 and later versions, some choices are

  a. DVD-VIDEO standard screen or 4:3 16:9 on DVD disc

  Both will have the frame size of 720 x 480 pixels. But the big screen comes with a 16:9 flag that extends approximately 856/480 16:9 display video after encoding. The screening is not adjustable by the user... and you end up with the DVD-VIDEO format @ 29.97 images per second interlaced.

  b. format of the AVCHD on DVD

  Here is the video display 1920 x 1080. And, depending on the version, can be 29.97 images interlaced per second, or 23.976 progressive frames per second (if not just 29.97 images per second interlaced). Although you can generate some AVCHD DVD with a regular DVD burner, DVD AVCHD is in need of a blu - ray player that supports supported AVCHD DVD or one of these drives multimedia multi which is also.

  c. If the player allows... you can export your Timeline file saved on a USB Flash drive and then insert this USB Flash drive in the drive to get the reading of the file. On this route, you can set the Premiere Elements avancΘs to customize your choice of export preset.

  Please consult the bulletin and consider then, let us know if we have targeted your question. If this isn't the case, please give more details in the areas where we do not have.

• form created in the ES4 will not save the data entered in acrobat readerXI

  I created a big form in Live Cycle Designer ES4. If I save the form in pdf format and open it in Acrobat Reader XI I get the message that I can't save the data entered in the form only print it. All I want to do is to put the form on our web site for people to download, fill out, save, and send it to me. I consider another method that is if I distribute the form and take the distributed pdf and save it locally, when it is open in the player you get the Send button on the purple bar on the right side. This will confuse many of our users, so if there's a way to not have the submit button so that work, but how do I stop the send on the purple bar button?

  You must activate the reader of the form. You can do this in Acrobat 11 open the form in Acrobat and select: file > save as other > Reader Extended PDF > activate tools more

  11 reader can save non-active AcroForms (created in Acrobat Forms), but not the forms enabled for the XFA (forms created in LiveCycle Designer).

• Cannot save the data

  I get the message "Cannot save the data" every time I try to open a single file CPTX. other files work fine. When I open the file, it gives me that message box, I click ok and another box says "a fatal error has occurred and the application is being completed. "and Captivate closes.

  I cleared the cache. I also tried to find and rename the Preferences folder, but I don't see any preferences folder or file in the \AppData\Local\Adobe\Captivate 5.5\ folder. Any ideas on what I need to do to fix this?

  The preferences folder is the folder "Captivate 5.5' in your profile (users\\AppData\Local\Adobe directory.
