• help the guitar hero automated using labview

  Hi, Im working on my final project for a class e and Im making a guitar hero automated using labVIEW and vision builder. I already have all the buttons and the strum bar, but I need help with the whammy bar. My problem is that it should only work on the notes which take more time with a single click, I think I should add some time delay (or something like that) so if the camera sees the note more times the amount of time its will send a signal to the solenoid to continue to press the whammy in intermittent form bar (I think I need a square to wave this) part).

  I'd really appreciate if someone can help me or show me an example implementation of the part.

  Here is a video of a similar project without the whammy bar

  Edit: Im using a NOR-cDAQ 9472 module for output on a digital OR cDAQ 9171 chasis USB

  Thank you

  Dear Javier,

  It sounds like a cool project work.

  Why not try wiring of the output of the shared in a shift register variable to retain the previous values and compare the old with the new value using a door and.  You can connect to a wait function in your loop and wire abour 100ms, normal human reaction time, while is the button held for two cycles this triggers your whammy bar.

  I hope this helps.

  Kind regards

• extraction of volume changes to generate data automation

  I have two tracks. One is punchier it's synth strings all

  I can extract the hard-hitting track volume level changes to generate data automation?

  I would reverse the Automation data and apply it to the second track.

  The effect I'm trying to achieve with each beat of a drum, for example, the volume of the synth breaks down.

  Is there another way to do this?

  Looks like a great app for a compressor.

  Install the compressor on the synth channel online and have the input of the side chain linked to your drum channel. Adjust the parameters of the compressor (threshold, attack, release, ratio) of taste.

• Automing instruments LabVIEW without using specific and coding drivers for each instrument?

  Hello

  I'm new to programming in labVIEW, but I had a few questions about its use in automation and remote controlling several instruments.

  It is an ideal software for automation of various instruments remote control/test. Assuming that I have several different companies spectrum analyzers, I understand that labVIEW drivers of instruments or special VI who would control these instruments. But if I wanted that all these spectrum analyzers to say, to display on another computer using the remote control, but I wanted to use the same program for effeciency, is it possible to do so universally for all instruments using labVIEW? Or do I have to adapt this program for each instrument to instrument drivers cause?

  If labVIEW can do that, is - anyone had good success for such scenarios in other programming languages?

  Thanks in advance for your help.

  Look for the Abstraction Layer material (that you can implement with LabVIEW, even if it's a slightly advanced topic).

  The idea of having a specific Test and be able to enforce it against different Instruments, decided at run time, is the kind of situation that LabVIEW and use of HALs was designed to facilitate.

  The concept is to 'Levels of Abstraction'.  When you create a test, you can design it for an abstract Framistan, since all the Framistans are supposed to be able to measure Vorbels in the range of 0 to 100, so you just plug a generator of Vorbel to generate Vorbels in a certain sequence of Test (linear, random, quickly, slowly, pulsatile, continuous, you decide), measure your Abstract Framistan records readings and compare with the results you expect write the results in a nice report.

  Of course, Framistat of OR uses Ethernet as the means of communication, while HP uses a serial port (depending on the model, series settings can change) and uses of the Intel one. DLL to communicate with the low-level API.  So you also need to develop, for each specific instrument, an "interface" between its API and the Framistan abstract (not everyone uses Vorbels as the input unit, for example).

  So the good news is that it can be done, the bad news is that one of the best ways of handling this type of question on the programming is to use OOP (OOP).  A number of languages (LabVIEW, C++, JAVA) support OOP, but LabVIEW might have the advantage when it comes to interact with the material.

  I you are looking for Hardware Abstraction Layer?  Add LabVIEW to the search query and you should find some nice presentations by Elijah Kerry...

• We can implement random generator lv in hardware?

  Salvation or

  I've been using the lv randomly in my project and now I want to set up my project in hardware

  can I implement this Randomizer LV in the material?

  If not then why?

  Please I need some details if you can

  Best regards

  Magnin

  The random numbers function is not available on FPGA. Good algorithms for random generation numbers are complex. I guess that the LabVIEW function calls one or more functions in the operating system that are not available on FPGA. Also the output random number is a floating-point, which was not taken in charge on FPGA, until recently (and I do know that if it is fully supported now, I have not yet tried).

• Write orders for specific data channels in report output via script or generating an automated script...

  In my project, I need to do some calculations, and then get the data plotted in the given report model. I use an automated for this script. My script is doing all the calculations and then he did not select and drag and drop the selected channels on the report model. His recording of the report template is empty.

  I'm fighting to get the specific channels data plotted using the script. I need the selected channels appear on this report template and then get saved.

  Any help will be much appreciated. Thank you

  Hi LaxG,

  If your script creates calculated channels, then you know what you're naming them - why your presentation of the STATE could not contain references to these names channels already?  Is it a dynamic number of conditional curves to the results of the analysis, or perhaps a dynamic number of REPORT sheets?

  You can programmatically change the reference of string of existing curves or the columns of the table with a VBScript DIAdem.  You can also add a curved column or a table with a VBScript DIAdem.  But the more you can save in the TDR file, work less you programming, this is the best place to start.

• 6 error when generating an executable in Labview 2009

  Any ideas on what is happening here?

  Hi David,

  I built an executable with the VI, and I could not reproduce the problem.  Have you searched and found the VI in the specified directory?  A couple of things to try:

  -Use the LabVIEW 8.x file structure.  This lie in the advanced the Build menu.

  -Try and build an executable with just that VI.  Who will tell us if it is a symptom or a cause.

• Implementation of the circular buffer for LabVIEW 8.5

  Greetings,

  Several weeks ago, I downloaded the application of a circular buffer for LabVIEW 8.5 of ni.com. The current Web page is:

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/5883

  Unfortunately, this Web page has been updated since then and the files available for download (swcircularbuffer1.0.19.zip) are for LabVIEW 8.6.

  So my question is: where can I find the application of a circular buffer for LabVIEW 8.5?

  Thank you very much!

• implementation of a function of time transfer real Labview program

  Hello

  I want to spend my control signal U through the 146 function /(S+276) for U_filtered

  How do I?

  I tried a low-pass filter, but I have the same results in comparison with Matlab.

  I mean I want to have:

  U_filtered = 146 /(S+276) * U.

  I have attached a picture for the signal U (yellow) and U_filtered (pink) in Matlab.

  I want to use in a real-time application

  Thank you

  How you implement the function of transfer in labview?

  I think this should be a separate implementation and maybe you already do. So forgive me if this is something you already know.

  Please see http://en.wikipedia.org/wiki/Low-pass_filter#Discrete-time_realization for an excellent time discreet introduction, low-pass filters.

  Essentially, you have to implement a discrete equation to achieve this. Something like:

  y(k+1) = 0.53 * alpha * x (k) + (1-alpha) * y (k)

  where alpha is related to the low-pass frequency and the frequency of sampling by alpha = flp /(fs+flp), flp is the low frequency of success and fs is the sampling frequency.

  In your case, flp = 276 and fs, it's whatever you choose to implement: it is the speed at which your loop runs on the RT or the FPGA or whatever. If speed is not a problem, I recommend 5000 rad/s or above as a starting point.

  The factor of 0.53 above is just the gain of the filter described you 146/276.

• use excel to generate signals in labview

  Hello

  I have an a problem generating a signal in labview using excel and then he charted under the waveform.

  In excel file, I 2199 rows and 9 columns with the second time and I want to draw time against other columns except column 1. In the rows, I have the text first.

  Any help much appreciated.

  Thank you

  A simple thing you can do. Open the Excel file and save as delimited .txt file and use the reading of the spread sheet file to read the data and then remove the first line and convert DBL and then draw it.

  Good luck
