• How to implement point filters fixed for FPGA

  Hello!

  I am applying the bandpass filter Butterworth for FPGA.

  I managed to develop filters of fixed point that suits my needs, but I don't know how to implement on a table in a project after the FPGA code generation. I tried to understand it in the examples, but I was not very successful.

  My time to finish what runs, any help would be really appreciated...

  Any suggestions?... some examples?

  Thanks in advance

  I've already done that and solved the problem.

  In any case thank you and have a nice day

• How to implement the reading of data from a matte file on a cRIO?

  Hi all!

  I'm still not sure, it is plausible, but I'll ask rather before you begin complicating. So far, I found no useful information on reading in the data to a device of RT from a file (type of a simulation test - data is simulated).

  I have the MatLab plugin that allows the storage of data read a MAT file, which has a number of columns that represent the different signals and lines representing the samples at a time (depending on the time of the sample - sample every time has its own line of signal data).

  I have no idea how to implement this at cRIO.

  The idea is:

  I have some algorithms running on the controller of RIO in a timed loop. As the entries of these algorithms I need to access each of the values of columns in the row, which is the time of the sample (sort of a time series - without written actual times).

  I am fairly new to RT and LV development, so any help would be appreciated.

  Thank you

  Dear Luka!

  I think the reading of all the samples in a single channel is exactly what you need here, because reading the files may take some time and is not deterministic, so it is best to read all the data in memory (or if this is not feasible due to problems of size, fairly large pieces may be sufficient). The table read can be provided and then in the loop simulating outings, something like this:

  

  I used here separate channels so it's more graphic, but you can build all the channels in a 2D array and array index corresponding to the samples fom 1 who. You can also use for loops with indexing as tunnels are setup and then you won't need the index functions and the number of iterations is also set automatically, but you have to take care of synchronization settings.

• Difference between C/C++ Native Development & Cascades QT C++ development

  What is the difference betwwen development C/C++ native development & C++ QT Cascades.

  I assume you're referring to Kits SDKS listed on this page:

  https://developer.BlackBerry.com/DevZone/platforms/BB10

  C/C++ native Development Kit is everything you need to encode a native C/C++ application to run on the BlackBerry PlayBook and the next BlackBerry 10 devices. The API described should give you everything you need to develop all the components of your application, from the ground up. If you have an existing application, you can probably start here. This SDK is ideal for access to the low-level API.

  However, it does not come with a user interface toolkit. You have literally everything code yourself, or help existing libraries to the port for you. You probably don't want to do. Instead, you can watch the C + c++ / Qt Cascades Development kit. This SDK provides you with everything you need to develop an application for BlackBerry 10 devices to come. You can still access all the low-level APIs, if you need it, but because Qt adds so much and is so powerful, almost everything you need is probably already there.

  Basically, Qt will provide you with the API call and use in your application. These libraries are open source which have been reviewed for many years and will probably accomplish everything you need. Go further, Cascades is the toolkit of user interface of choice in the native development, as it offers UIS amazing, fluid and easy implementation in your application.

  Note that I never mentioned the PlayBook by discussing the C + c++ / Cascades of Qt kit. The PlayBook is not supported with native support for this mode of development, but it will come with 10 BlackBerry is released later this year.

  Basically, the native C/C++ SDK provides you with the nuts and bolts, you must develop an application from scratch. But why would you, when C + c++ / Qt Cascades Development kit includes many libraries for things you probably want to do.

  Unless you develop a game, a porting library, or the need to develop for the PlayBook today, using C + c++ / Qt Cascades development kit.

• How to listen to what Native Application opens

  Hello

  I'm sure it's pretty trivial, so I'm sorry that if it comes to an easy question, AS3 is far from my point hard.

  I had a peek here http://help.Adobe.com/en_US/FlashPlatform/reference/ActionScript/3/Flash/desktop/NativeApp lication.html but I'm not 100% sure class that will help me achieve what I want to do and how to implement this code.

  I want to just run a function when the native application opens again?

  If someone could help me or let me know if this is possible, it would be great.

  Thank you

  Alex

  Hi Alex!

  Use the Event.ACTIVATE in nativeApplication like this:

  NativeApplication.nativeApplication.addEventListener (Event.ACTIVATE, onActivate);

  function onActivate(e:Event):void {}

  What you want to do here

  }

  Have fun!

• How can implement you not with Tim Capsule and AirPort their simulation on the iMac?

  Hello

  How can implement you not with Time Capsule and AirPort their simulation on the iMac?

  I don't know what you're asking.

  AirPort Extreme is a wireless router.

  A Time Capsule airport is an AirPort Extreme with a built-in hard drive for data storage.

  An iMac is a Mac computer.

  An iMac is not a wireless router, so he is unable to perform the functions of a wireless router.

• 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,

  Dennis DG

  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:

  Learn how it works and try to adapt it to your specific task.

• How to implement Canopen on FPGA to run the engine using NOR-9881?

  Dear,

  Your support will be highly appreciated,

  There is only one available for NOR-9881 example.
   
  Please note that the following materials were properly connected:
  cRIO-9024, cRIO-9113, OR-9881 and motor Nanotec (SMCI36 against L2818L0604-T5X5), the following
  sites Web shows the engine Nanotec in details:
   
  http://us.Nanotec.com/products/660-L28-linear-actuators-with-trapezoid-spindle/
   
  http://us.Nanotec.com/products/1041-SMCI36-stepper-motor-and-BLDC-motor-position ing-control /
   
  The main problem is how to configure the inputs and outputs, where, in most examples, the entry and exit have been automatically
  configured.
   
  the following three examples and I wonder how to start:

  1 - example Nanotec: dependent VISA controls for data transfer
   
  http://us.Nanotec.com/support/application-notes/LabVIEW-example/
   
  2 - reference example CANopen for series C OR - 9853 Module CAN:
  the NOR-9853 has default Can0 which was used in the code

  http://zone.NI.com/DevZone/CDA/EPD/p/ID/6093
   
  3 - from finder labView example: search for 9881 then choose
  NOR - CANopen_cRIO.lvproj, which depended on SDO orders for transfer orders
   
  The attached picture shows that NEITHER-9881 can be seen, after compilation and
  loading the bitfile FPGA.
   
  Please, please advice me:
  1. how to start?
  2. how to create variables of entry for NI9881?
  3. how to implement CANopen mode FPGA? where there is no CANopen palette.

  Thanks in advance and

  Hello!

  From my understanding, the 9881 can be treated from the FPGA, but only from the application of the RT. I think that the point 3 of your post examples of the use of the module fine.

  Kind regards

• How to implement interfaces or inheritance in LabVIEW?

  Hi all

  I try to implement oriented OBJECT in my LabVIEW code and require heritage or just an interface (such as might be required in java).  I have a good knowledge of OOP is just how do me in LabVIEW, I'm curious.

  I'll try to stick with my own example for now, so that someone is able to tell me exactly how to implement this.

  in any case, I have two different DMM and each come with their own GPIB commands to get the measures and set the measurement configurations.  This seems to be a perfect example to learn how to use inheritance.  I figured out how to make a class for each DMM but was curious as to how I might be able to create a parent class for each of them because they both require the same fields in their configuration (AC/DC, Measurment Type, rank, address VISA).  I think that I could create a parent class with these fields, then the methods of use of these fields and have then child classes inherit fields and override the methods of the parent class so that depending on what the user selected DMM, it would be able to use the correct class to issue the right GPIB commands.

  If anyone can point me to a good example or explain how this could be implemented in labview that would be super.  I'm also browsing the forums LVOOP to LavaG trying to figure this out, thanks!

  Brent

  Brent,

  LabVIEW help contains a lot of detailed information on the use of classes.  I recommend reading through it, before we begin with OOP in LabVIEW.  In the content of the Help window tab, search for "Fundamentals > LabVIEW Object - Oriented Programming > How - to's»  There is an article entitled 'change the legacy of a LabVIEW class' that should be what you're looking for.

• How to implement the ScreenUiEngineAttachedListener Interface?

  How to implement the ScreenUiEngineAttachedListener Interface? It is somewhat a mystery reading through the API.

  I have a class that implements ScreenUiEngineAttachedListener:

  public class UiListener implements ScreenUiEngineAttachedListener {
    public void onScreenUiEngineAttached(Screen screen, boolean attached) {
    }
  }
  

  Then I have a class MyScreen which extends from screen and has two methods:

  public void addScreenUiEngineAttachedListener(ScreenUiEngineAttachedListener listener) {
    super.addScreenUiEngineAttachedListener(listener);
  }
  
  private void removeScreenUiEngineAttachedListener() {
  
  }
  

  • What is the correct positioning of everything?
  • Can I define an instance of UiListener and pass in the addScreenUiEngineAttachedListener?
  • How to remove UiListener in removeScreenUiEngineAttachedListener?

  You will need:

  • an instance of your UiListener - probably a static member inside your UiApplication;
  • a method that allows to retrieve the reference to this instance of UiListener;
  • a call in your constructor for the screen at addScreenUiEngineAttachedListener (yourApplication.getUiListener ()) or similar;
  • potentially a call within your onScreenUiEngineAttached (attached screen, boolean) routine, the branch (attachment is false) : screen.removeScreenUiEngineAttachedListener (this);

  However, all this is too much work for no gain. Just override protected void onUiEngineAttached (boolean attached) in your screen class and make your logic there - all members of your class are accessible and all the code is placed where it belongs.

• just to start native development - momentics ide or Visual Studio

  Outings to start to write some Aboriginal stunts based apps.  First off is always supported and strengthened Cascades / maintains. What development environment is best for Cascases / native development. I am very familiar with Android Studio, Eclipse and Visual Studio. Momentics still supported and that of using or moving to the Visual Studio plugin? Who has the best features in terms of aid to development for native applications and the productivity of developers?

  Thank you

  Brian

  Cascades is the library preferred for native development, then Yes, it is still maintained and will be for the foreseeable future. If you are familiar with eclipse you'll feel at home with Momentics, which is a custom eclipse build specfically for the development of Cascades/Native BB10. There is also a plugin for Visual Studio, but almost everyone posting here uses Momentics BB10 development.

  Personally, I much prefer Visual Studio, eclipse, I always felt suffers greatly from trying to be a Jack-of-all-trades and have been cooked over a long period of too many heads. Don't look under the hood of the eclipse unless you want to tear your hair into small pieces. That said, my first attempt to use the VS plugin didn't look good, and I quickly discovered there is not much here that can help you with it. I would recommend that you go the Momentics road despite its many flaws.
