• How to implement the wafer map using LabVIEW?

  Hello LabVIEW Masters!

  I have a project which includes control and searching for information on a PROBER. One of the difficulties I have now is how to implement a WAFER card using LabVIEW. According to the requirements of my client, the element of pads varies between 6 k and 23 k. I guess that do everything (a = a ctl/indicator led) will be a hell of a task, especially on how to effectively manipulate each elements. Does anyone have a better idea on the way whose that?

  Please, I seriously need your help...

  Thank you and best regards,

  Hi Dennis,

  This wafer GerdW post card appears to me as a sort of histogram (for example http://www.ni.com/white-paper/4158/en#toc3);

  Altenbach post well this example that shows how to use a plot of intensity to create a 2d histogram:

• How to control the mouse cursor using EEG signals

  Hello world

  I am doing a project of cursor control using EEG signals. The idea is to find a way to all signals in a specific period of time in order to find the signal Ridge. Then, the highlight will be a parameter to control the position of a cursor.

  Can someone tell me the function that allows you to control the mouse cursor?

  I also found an old topic asking about it (http://forums.ni.com/t5/LabVIEW/Moving-Mouse-using-Labview/td-p/1285842) and I run an example of this link ( smercurio_fc) program. My cursor is stuck in the upper left corner of the screen, I can't control it again. Can you tell me how to run this program and to use the windows API?

  Thank you in advance.

  Sorry, but I can't do it for you.

  As I advised, you should take the free online tutorials. You clearly lacks the basic concepts of LabVIEW, as data flow.

  Things more: in your real applicaton does not use DAQ Assistant, screw Express are generally not optimal for data acquisition. It is safer and better use good DAQmx live. What is the equipment you use? Sampling rate, etc.?

  Why do you need to read data files? For testing? I thought that you will acquire data active, right? In your VI generate you some signals and write in a data file. Is this also for testing?

  There are several constructs in your VI which simply don't make sense.

  So again, I really suggest to go through online Core1-2 teaching material, which is accessible if you are a student, or if you have shared services provider license... It will really help.

• How to control 2 motor epos using microcontroller 50/5

  Hello. I did a program of integrated epos of labVIEW for control 1 motor epos. I make the program using the sub - vi from labVIEW epos data, but I don't know how to control 1 motor. Can anyone help me or tell me how to control 2 motors or wad is necessary? Thanks for your help :-D

  Hi Spydi,

  I don't think you need the CANopen library since you already use the instrument EPOS Driver.

  Currently using a NI-CAN device to connect your controller? This is a device for both engines I think?

  We are not very familiar with this set of drivers because it is not created by NOR, but I think all you have to do is to change the axis of entry to determine which engine is controlled.

  So probably your first engine corresponds to the axis 0 (default value in the example program), then your second engine corresponds to the axis 1. When you want to send commands to the different engines, set the ID of node/keyhandle axis accordingly.

  I hope this helps.

  Best regards

• How to interface a simple way using LabVIEW 2009 simulink model and SIT?

  Hello

  I finally found a way to use a template simulink with LabVIEW and the Toolbox to SIT, but I'm not satisfied.

  If you have any suggestions, the link of resource that I missed, please do not hesitate to answer

  Note that I do not know much about simulink, so that is my question seems stupid, let me know what

  Software configuration

  OS: Windows (not an RT target)

  LabVIEW 2009

  SIT 2009

  question 1: interfacing the model DLL (mapping considerations) with a driver VI

  We have created a model of DLL by using the 'Workshop in real time' tab in simulink.

  In LabVIEW, launch us the tool 'SIT connection manager' and try to use the DLL with a driver VI by mapping the e/s model for screw/lights orders.

  The fact is that I fail to connect to my controls/indicators VI/o model because they do not appear in the mapping dialog box.

  The simulink single objects that I managed to map are "constant" and "test points" while I need to edit the template simulink itself (example below)

  

  Are in e/s model, not considered as part of the parameters of the model? (this could make sense because the mapping says in fact that it operates on "model parameters")

  Is it possible to link the IO model VI commands/lights?

  Note:

  -the "configure HW i/o mapping" dialog box allows me to map model e/s with e/s HW...

  -The examples also use these "constant" and "test points".

  2nd question: use of direct screw SIT

  I tried to use the DLL directly with the screws SIT (code example below)

  This kind of code works well on another project (target of 8.0/RT LV) but not on the current project (LV 2009/Windows)

  The second stage of the model never ends:

  -0-index of the loop works as expected (model doing its job).

  -index of the loop 1 starts normally, but execution is stuck in the 'SIT scheduler.vi.

  Then I have no choice that to kill LabVIEW ("Reset screws" windows appear if I try to stop/close them).

  

  Is there a reason that I do not see what explains this behavior?

  Thanks for reading.

  Any help appreciated.

  Kind regards

  Hello

  I spent some time analyzing the VI driver as you suggested.

  Here are my findings.

  Question 1: the SIT connection manager does not pass to the model SW controls/indicators. Only, it allows the user map HW AIs/AOs.

  The only solution I found (to have a SW - for example a shared variable - object that is mapped to an input/output model) is to customize the VI driver that is scripted by the SIT Connection Manager ("_Baserate Loop.vi" in the flat sequence structure named "read code")

  Question 2: after spending some time in the VI driver, it seems that the VI to call right is not 'SIT scheduler.vi' but 'If SIT take model no time' (which uses the other as a Subvi)

  

  My conclusions are correct? If I use the API in the wrong way, please let me know.

  Kind regards

• 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

• How smooth a XY chart by using Labview 6i?

  Hello

  My main Vi captures the data that I sent to a XY graph

  

  I would like to smooth out the curve before and after ('not ok' on the photo) the main peak ('ok' on the photo)

  I looked for aboard or and have not found anything that I could use with Labview 6i

  Does anyone have a solution?

  Thanks in advance

  See attached simple vi with data and graphics

  There are several options:

  1. Use the filters in the range of Signal Processing to smooth the data.
  2. Fourier filtering techniques to smooth the data.  Fourier transformations are also in the range of Signal Processing.
  3. Use almost any technical standard smoothing.  To view the online version of the Numerical Recipes many methods.  You will need C in LabVIEW, but it's pretty easy.  Savitzky-Golay smoothing is especially good for this type of problem.

  You will need to convert your XY data to waveform to get one of these at work.  If you data are spaced regularly, it's pretty easy.  If they are not, you will need to make some kind of interpolation.  Or you can simply ignore the fact that you have unevenly sampled data, convert a waveform, smooth, then convert back.

  A word of warning.  The 'not OK' part of your waveform seems to have important characteristics.  Putting my hat physicist for a moment, are you sure you want these pics gone?  This is also true of the myriad of small peaks around the main one.  Be careful.  A better approach might be to eliminate differences in gain in order to have a flat bottom (1060nm region - 1080nm), and then try to model the peaks of interest.  You could also take multiple series of data and to get rid of some of your sounds, average your X-scale condition is stable.  But it really seems not to be much noise on these data.  Most seem to be important.

  No you can not grow directly in LabVIEW and deploy this program to the Board of Directors Zync. NOR has their own material base platform Zync (cRIO and myRIO) but the tools to target these tips are specific to the hardware implementation OR and will not work with other hardware. Develop an interface for another hardware platform is a lot of work and must be adapted for each unique flavor to a new hardware platform. And NEITHER does not support this for other devices.

  If your option will be to develop an application with the SDK Zync for Zync ARM controller and provide a form of communication interface (serial port, TCP/IP, or similar) to this application you can send commands to LabVIEW for your embedded application.

• With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable.

  With LabVIEW how to control an instrument with a RS232 output, using a USB RS232 converter cable, since I do not have rs232 ports. I have two instruments I want for the control in this way. One is a guarantee of strength Imada SPAS with RS232 output. The other is a micrometer Panasonic HL-G103-S-J laser sensor which is RS422. I have done significant programming LabVIEW using GPIB, but I have no experience with devices such as these. No matter what tutorial or examples would be greatly appreciated.

  Thank you.

  When you plug the USB-RS-232 converter, it installs a driver under Windows which makes it look like any other RS-232 port.  You may need to install the driver of everything that came on the CD with the converter.  It will get a Com as Com5 port number according to what is the next available number.
