• How to generate random curves under image control?

  Hello

  I'm still in the learning process LV my current objective is to have a circle drawn in the image optimization to move everything in the path of a curved line. The problem is that whenever I run the VI a new different trajectory is programatically created for my circle.

  I don't know how to approach this problem.

  A similar VI, I had the balls moving linearly, so I simply added a speed component to the component of the position of my balls. I initially use the same design here, but I can't devise a set of rules that would make the change in the result of the position on a trajectory of curved line. I think that generate a picture of the whole trajectory before each execution would probably work here, but I can't think a function do it either. Play with basic trig led sinusiodal or curved trajectory, but nothing really random out of period and amplitude.

  Ideally, I want as much possible variance in the path (ex: a function that could give me S, U-shaped, in the shape of spiral, loop, etc.) while maintaining control of certain parameters (length, position, max dX, etc..)

  Someone has an idea?

  Thank you!

  Looks like a random Walker.  One that I just did.  At each time point (0.1 seconds in this example), he took of the unit step in one direction, with the changing direction by a random amount within an angular range.  It can get pretty wild...

• How to generate an impulse to test short circuit in an inducer

  Hello

  IM new to labview and am in need of complete SURG - SURGE STRESS TEST

  This test is intended to detect a short tour inter by applying a number of high
  voltage pulses (or surge) for the selected winding.
  Each pulse should produce one sinusoidal transient that eventually decreases to zero.

  How to generate the impulse using labview.

  Hi Jessica,.

  Please see the "pulse pattern.vi" function--> pallets of signal processing signal generation.

  Otherwise, you can browse through examples of LabVIEW.

  Kind regards

• Problem call Matlab external function under Labview 7.1

  Hello

  I have the problem when I want to call my m.file function in the script Matlab under Labview 7.1, that labview does not seem to be able to find this external Matlab function. I searched this forum, someone talked about setting search path in the tool-> option-> Matlab search path, but it seems that it does not exist in the version 7.1.

  Is it possible to solve this problem in version 7.1 or update to the latest version, the only solution?

  Thank you

  Hello

  I think you're confusing the LabVIEW MathScript nodes and the MATLAB® script.  The MathScript node is introduced in LabVIEW 8.0 and the setting of path search that you speak to MathScript, reason why it does not exist in LabVIEW 7.1.  Look at the example of differential equation Lorenz for the MATLAB script node.  It shows how to set the path of research to be compared to the VI.  The example is found in the node of script examples\scriptnode\MATLAB - Lorenz Diff Eq.vi.

• How programmate a waveform arbitrary in LabView for an AFG3102C?

  I am trying to send a LASER pulse which is controlled by the CH1 of my signal generator. This is typically a 1us pulse, followed by a variable period (of 300ns to 10us) and then another pulse LASER to 1us.

  I don't see how I could program in LabView without using another program (i.e. Visual Basic).

  I'm using LabView 10.

  LabVIEW is capable uber; including in the instrument control.

  There is an instrument driver for the AFG3102 provided on the Web site of NOR. Download you and use the library of Virtual Instruments (VIs) comes with the LabVIEW environment. There are tutorials on how to do it. You can see the libraries supports GPIB/USB/Ethernet, so you must use one of these protocols to connect to your device, and then configure it within your own LabVIEW VI; You can reference the file 'Plug and Play' on the page driver instruments first to see how the device is controlled in LabVIEW for a sample application.

• How to avoid the launch of Labview VI when he invokes in Teststand environment?

  Hi, friends.

  I am a student of teststand. I wrote a few screws by Labview. Now, I want to invoke in teststand environment.

  But when I run the sequence. LabVIEW automatically launches.

  How to avoid the launch of Labview when I run the sequence?

  Thank you.

  LabVIEW programs require a runtime engine. Under the TestStand configuration drop-down, select adapters. You can change the LabVIEW adapter to select the runtime rather than the development system.

  This should prevent the main screen of LabVIEW to appear, but you will not be able to change your LabVIEW VIs while they run of TestStand using the runtime engine.

  The correct method by using the pump of the database or import/export or unload the data in CSV format for loading using SQL * Loader.

  Generate instructions insert with literals is very bad choices - the bind variable is missing. It will be quite slow because many other CPU cycles are spend on hard analysis. The shared pool will become fragmented. This can cause errors of memory for other applications when they attempt to analyze SQLs for cursors.

• How to generate XSD to the basic service in CC & B

  Anyone know how to generate XSD to the basic service in CC & B? Any suggestion would certainly help me. Thank you

  Take a look at the XAI best practices whitepaper that you can find on the Oracle Support under 942074.1

  Note that it is not recommended to use the schema editor to define the XSD for maintenance Object Services. Rather consider using Config tools.

• How to change the time timestamp labview at the UTC time

  Hello

  I have table of database in UTC time field.i select and insert data in the database table based on labview timestamp controll.

  example:

  Table:

  S:no U.name PWD Epoch (UTC 1970)

  1 1450422341 123 kumar

  mock 2 786 1450421623

  the era of labview is difference from UTC time. so ADD this second 2082844800 at the time of labview that it will work for selection quary but time insert is not a job.

  Here's how to convert a timestamp of LabVIEW to a timestamp of Excel (OLE).

  

  Red the explainiation down and I'm sure you can figure out how to change it to get the party time you need.

• How to completely uninstall a computer labview and avoid to occupy the license

  Hello

  Usually a labview can be installed on three computers. Now I already installed all and will install in another computer. So I need to uninstall one of the three and want to know how can I completely uninstall the labview. Thanks a lot for your help.

  Use License Manager TO deactivate the license.  Will release the database entry of NO, so that you are OK to activate the license even on a new machine (can't really uninstall LabVIEW - the absence of activated license will prevent the use).  As I remember reading the license agreement, you can do up to 4 times per year.

  If you do not have access to the old machine (that is, because it fell from the roof or something like that) call OR service and they can manually remove activation.

• is it possible to tell me how I can make program in labview that take black and with image pixels and give the coordinates of black or white pixels again to me.

  Hello everyone

  is it possible to tell me how I can make program in labview that take black and with image pixels and give the coordinates of black or white pixels again to me.

  It depends on the image and the module LabVIEW available to you. LabVIEW can open bitmap and png files and convert them into tables: if it's really a monochromatic (depth of 1 bit) you get a table 2D boolean, T for white, F for black. Just look at the index of the item to its details (don't forget that LabVIEW does not use the order of rows and columns, so you must transpose and reflect the table). If you have a 24 bit bitmap, the table will contain the color in hexadecimal synthesis (000000 for black, FFFFFF is white and so on); Yet once, you simply check if the element of the array correspond to your requirements and get its index.

  With the vision that you module con open other pictures and perform advanced on them without convert them into tables. Anyway, you can just type the extension of your image using LabVIEW and see what you get.

  Here is a code snippet to open a monochromatic image

  

• How to avoid the launch of Labview when called by Teststand VI

  Hi, friends.

  Thank you.

  I'm not sure that I follow what you're saying...  But it seems that when the VI is called, the LabVIEW Development software is started and you want to avoid this.

  If you create an executable file or a dll and that any call within TestStand, she should not call the development environment.  You must have the LabVIEW runtime engine installed on the target computer.

  For several years I used TestStand with LV, if my memory does not have to be precise.  I think that the above worked for me.  However, it seems that I remember something to have the LV code in debug mode, causing to open development environment... but it's a distant memory.    You do not use breakpoints where the LV VI is called, are you?
