• How to randomly choose excellent data using labview.

  A very good day to all. I am currently working on a system that will be selecting whole number of together generated at random in number. If this is not possible, I would like to the system to be able to select the number of the set of numbers that have already been generated randomly from excel. kindly help me with the solution. To get clear, assuming I put numbers 1 to 10, I want a labview setup that will recover these numbers one after the other or with replacement without excel or auto generated. I know it's possible in matlab, but would prefer if possible labview.  Thank you

  More, otherwise all of the languages that I ran across were a rand() function returns a random number between 0 and 1.  Get some other range belongs to the programmer.  The usual method is to multiply by the beach, you need and add an offset to adjust the average.  For example, if you need a random number between 200 and 300, the formula can present themselves as "rand () * 100 + 200". "   If you need an integer, you can use the round function (who, it will remain as a float with no decimal pportion) or conversion (all).    All this is feasible and direct in LabVIEW.  Take a look: http://digital.ni.com/public.nsf/allkb/FCCDCD678EEF3A9186256D7B008054F5

• reading data in labview to accdb file

  Hello.

  All I want to do is to read the data into a file (MS Access 2007 and later) .accdb and be able to use these data in labview. It's just a table with a group of numbers. I know how with excel but I'm getting confused with MS acess. I'm trying to play with LabSQL right now but still get confused.

  Help, please!

  Thank you.

  What are you specifically confused about? Before using LabSQL, I suggest that you find a good tutorial on the SQL language. Database Toolbox of OR can also be used. It hides some of the complexity of the SQL for beginners.

• Graph of the Excel data with overlay of dynamic data acquisition

  Hi all

  I was next to the forum of Labview for about a year, it's the same with my programming so I'm a little rusty. I don't have someone code this for me, but just a quick plan high level to point me in the right direction.  I am able to work through the tutorials Excel etc.

  Task 1: Basically, I have a set of data Excel (2 to 6 columns of figures, not the time) I want to read in Labview and throw in a XY graph as the base model that remains visible all the time.  This data set is quite long, length vs. size (length is 100km, 1 m intervals). I essentially want a scroll X graph to display all of the data.

  Task 2: Acquire a direct serial data string which will be superimposed on the graph of task 1 model. Acquired essentially data comparing data in real time to previously.

  In the past, I made the simple projects with Excel data reading and also the reading of data in series.  What I'm not clear on is how to create the (static) graph with Excel data model while superimposing live data as it comes.  It is the basis of an annual check of the investigation process.

  Advice on the process would be appreciated so I'll be working through the nuts and bolts.

  Cheers for any help,
  Wes

  If you are worried that your data sets is too large, then run a test with simulated data to see how LV takes it. You might be surprised. In all cases, you should be aware that the chart control will need to redraw it with any changes you do anyway, and as far as I know, having a large amount of data is the main thing that can make a slow chart control. If you find that you have too much data, you might need to decimate it you based on how much you zoom before putting it in the graph.

• Data of runtime of overlay on top of excellent data

  Hi all

  I have data from Excel I want to plot them on a graph in LabView, while the data collection program, I would like to overlay the current data on the Excel data as a Visual top to ensure that the test runs well.

  Does anyone know where is an example of one such vi maybe?  Maybe you can give me some advice on how to do this?

  Thanks for any help,

  Hello

  If I did not have a maximum number of iterations, I would use a while loop instead. Otherwise, if there is a maximum number of iterations, a stop point can be added to a loop on the right by clicking on the edge of the loop and the conditional terminal option selection.

• you want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. A

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

  

• How to view graphical waveform Excel data

  I have a file .csv with 4 data column.  I found something for another thread that allows me to display data from an Excel file in a table.  I have a problem with the following:

  (1) I need to display column data 4 but I can't seem to find a way to add other elements to the Invoke node so I'm stuck with power display only 2 columns of data.

  (2) why can't take my output and put it in a table, and then view it on a waveform graph?

  Please take a look at the attached VI.  I took notes in the block diagram.  When I try to join the Excel data to a chart, it indicates that the source type is a string, while the sink type is double.  How can this be when the Excel file has only whole?

  Help, please.

  Thank you.

  
  

• Dashboard of data for LabVIEW with ad-hoc wifi?

  Hello

  We have a laptop and we run a LabView control and acquisition of data on this subject program. We would like to have access to some of the values of the "indicators through an android tablet, so during an operation manual tap on our facilities, we could see remotely what happens with some measured values in our application LabView.

  The ethernet port is not available on this laptop, it is used for a sensor. It has wifi and bluetooth adapter. What would be the easiest solution to access the LabView app on this laptop from the Android device by using the "dashboard of data for LabView" android app? For security reasons, this laptop can't access internet, but of course, we could all just put a near wireless router (and not connect to the internet), and the laptop computer and the android Tablet access the same wifi network. I guess it should work, Yes?

  Or is it possible to make a connection to wifi ad-hoc between the laptop and the Tablet and use the DataDashboard? Anyone has any experience with such a solution?

  Last question: or what a Bluetooth connection? Might work?

  Thanks a lot for the tips!

  Kind regards

  Hi man,

  I recommend you connect your tablet as you described.

  I don't think that it is possible to use the Bluetooth with the application of the dashboard of data for Android. I can't find any information on Bluetooth, only for the WiFi.

  Rather than trying to create an Access database, I have simply included a blank database with the installation.  Open, build the tables as required (as your example shows), and then copy (using the copy of the palette of Advanced File i/o) whenever you need it.  Your program will need to know where it is, therefore, store the connection information in a configuration file (as already mentioned) is a possibility.

  Here's how to use a connection string to open a database:

  

• Data for LabView - Motorolla RAZR dashboard

  When view LabView, the Android Market data dashboard tells me, 'your device is not compatible with this item."

  I have a Motorola RAZR.  Any suggestions?

  Hello duane,.

  At that time, dashboard of data for LabVIEW is available on shelves.  In addition to the Apple iPad and iPad 2, Android tablets only under 2.3 or later are supported.  To support the Tablet 7 '' Android, we had to make some design changes.  It should be even more changes due to the small size of a phone.  We might consider a version for phones based on the popularity of the application on each platform and the information received in return.  For more information, see the product page or the LabVIEW Web Interface Builder and data dashboard discussion forum.

• How to import a table of excel data in my site with DW CC?

  Hello!

  Im trying to insert a table of Excel data in my site, but when I do, the information are delivered with a large number of dirty codes making my Dreamweaver CC accident...

  I'm using File - Import - tabular data.

  Thank you

  Maria

  If you get a lot of formatting and garbage of Excel who causes an accident, you can first save your file as a delimited file and which allows to import into Dreamweaver using the same steps as import it tabular data.  These files are much cleaner and easier to import.
