• More questions about custom asynchronous device

  I am trying to create a custom asynchronous device for VeriStand and have the following questions:

  (a) at what rate entered in the course of analysis and data channel pushed into the FIFO of the custom device entry? The scanning speed depends on if the input channel is mapped to a control of workspace object or if it is mapped to an output of the simulation model (.dll file)?

  (b) at what rate the VI real-time asynchronous custome device running? Is it at the same rate as the primary control loop rate? Can I change the rate of implementation of a custom device and how?

  (c) I have a quad-core PXI time real platform. How can I connect the device customized to a specific processor, like what you do with a simulation model (.dll file) in the definition of system file?

  Thank you in advance.

  Data FIFO

  The rate at which data are pumped on your meter is static and has nothing to do with the question of whether the workspace is connected, or if a model is mapped to one of your channels. By default, data are pushed in input of your Custom FIFO each iteration of the loop of primary control. If the FIFO is full, the oldest data packet is crushed. In addition, by default, outings THAT FIFO is controlled ever iteration of the loop of primary control. You can, however, use the NI VeriStand - Set custom decimation of device to mark a property on your customized device that will tell the system its decimation expected in the. If you set a decimation of 10, for example, the primary control loop will be send every 10 iterations of new data and check for new data out FIFO only every 10 iterations. This can help reduce the load of the processor in your system if you do not need updates that often.

  Similarly, you can use the NI VeriStand - Set of deep FIFO to control the depths of the FIFO of your entries and exits FIFO respectively. By default, both have depth 1.

  Delivery rate

  The rate at which your custom device runs depends on how set you up. You can for example, having your Custom asynchronous device uses its own schedule and run at a pace totally independent of the system. Your VI could have regular while loop with a 10ms timer, for example, or it could be based off some hardware device timing.

  Alternatively, you can choose yourself closely synchronize with the primary control loop. This by registering using a property that your Custom device has a timed loop that will use the clock of the device. The unit's clock is a source of synchronization that is checked each iteration of the loop of primary regulation after Custom peripheral FIFO have been updated. You sign up for this simply by calling the NI VeriStand - Set loop property Type specifying Timed loop to loop type and use peripheral clock be true. Then, as the VI model, thread just the clock of the camera in your calendar input source for the timed loop. If you have specified a decimation factor, as mentioned above, you should probably also to use this factor as your dt. This means that if you have a decimation of 10, you only run your timed loop 10 all the graduations of the source of synchronization clock of the device.

  Another simple way to synchronize closely with the primary control with a few problems loop is simply base your timing off the coast of the availability of new data in your entries or exits FIFO. To do this, you can simply use regularly to loop and then just wire - 1 for FIFO wait times. Then your custom device will run as soon as the data are produced and consumed by the system.

  Specification of a processor

  There is no property integrated for the allocation of the processor, but it will be very easy for you to implement yourself. You can specify the processor to run on in the Explorer system by creating a custom using NI VeriStand - property set the property of the element. For example, you could define a property of I32 entitled 'Treatment', with-2 meaning auto-affectation and any non-negative value indicating an index of specific processor. Set this property in one of your device in System Explorer configuration pages and then read the property in VI of pilot in the engine using NI VeriStand - get the property of the element. Then just wire up the value of the property at the entrance of affinity processor on your timed loop. However, you should always check that this processor is on target. Otherwise the timed loop will report an error and abort. It's exactly what we do for models in-house.

• Custom output device

  Hello

  Is it possible to create a custom "output device" in addition to the "Blackmagic" and "Firewire" those?

  If possible, how? There are some examples of project?

  Thank you.

  Hi Philippe_138! Welcome to the forum!

  Yes it is possible,

  the Basic sample you plugin on is called 'EMP' (external monitor preview).

• How can I remove a device synchronization to death?

  I would like to delete a device dead of Firefox Sync. How does this work?

  Hi bucmic04,
  For the moment, the device can be removed remotely. However, to remove the authentication on the device, modify the synchronization password.

  Keep in mind before you do, keep a local copy of your profile in order to preserve the locally synced data.

• Device synchronization

  I'm not the synchronization of devices, but I received an alert that a device is synchronize my account. How to identify this device?

  HI Anuck,
  There are two things that can be done:

  1. Go on behalf of synchronization on your Firefox browser and click on "manage...". »
  2. To disconnect unwanted devices, change the password. However, this will remove all devices from the account.

  Also to note that if there is an account in this preference on: preferences #sync an account is in fact attached.

• iTunes is not my playlist of device synchronization

  Hello

  I can't synchronize my playlist of the device after the upgrade of my iTunes to 12.4.2.4. Also, I recently upgraded my 5s to 9.3.3. Since then my device playlist will appear whenever I try to add a track on my device. I am able to view my playlist in iTunes, but when I add a new track he is inviting to create a new playlist and not to go for my playlist of existing device.

  PS: I'm using windows 7 on my laptop

  Thanks in advance,

  iTunes on my Mac is not synchronized songs or those playlists.  I came across this solution.    1. click on the little iPhone icon which is the upper-left hand corner of the iTunes window just below the volume slider.    2. now you should see, on the left side of the iTunes window, your iPhone on top with a list of (small fonts) 'Settings' which begins with the word 'Summary' 3.  Be sure to click on the word 'Synthesis' 4. To the right of this list, you should see gray boxes with the following 5 Options of backup iPhone.  In the Options box, be sure to UNCHECK "Sync only checked songs and videos" 6.  Now, back to the left menu and click on 'Music' 7.  You should see another screen (right) with the words "Sync music" in the Tope left 8. In the box below "sync music", click either 'library of music together' or 'selected, artists, albums and genres reading lists' I chose the option "selected playlists, artists, albums and genres."      After doing this, I was able to properly synchronize the songs and playlists.  Joe

• Synchronization with single device synchronization server

  Hello

  This must be a FAQ, but I'm not, so this is. How can I sync data from the server for synchronization to Mozilla to one device?

  The context is that I am currently running Ubuntu Linux USB on my computer at home, because the boot on this computer record has been corrupted, so I can't access Windows. I would like to download the synchronization (Favorites, passwords) data from the server to the copy of Linux in Firefox 25. However, all the help I can see refers to coupling devices. I see that I can create a recovery key if I don't have the camera with me, but there is a terrible warning in the dialogue of FF Sync key reset will erase all data synchronization. I don't have access to another machine to pair, as I work at home. I looked at the page 'How to manage my Firefox Sync account' (https://support.mozilla.org/en-US/kb/how-do-i-manage-my-firefox-sync-account) and have tried to follow the instructions, but again, I come to a dialogue with the terrible warning, and really, I don't want to lose all my data synchronization on the server.

  So, is it possible to sync between a computer and the synchronization server?

  Fred
  www.fredriley.org.UK

  Hello fred, you can connect only one device to your existing account synchronization when you have the username, password & the available existing recovery key - you can do so in Preferences > sync > set up sync > I have an account > I don't have the camera with me. so you would need to know the current recovery - don't reset as it will remove all current data on the server as noted in the warning messages.

  Another way to import your old data would be if you still have access to the file system of your windows machine. then you could import some files from your old profile windows in your current profile folder in order to restore some data like bookmarks, paswords, history, etc.: recovery of data from an old profile

• Custom refresh device channels instead of remove device

  One of the great pains that I have met is when you change i/o on a custom device, you must remove and re-add the device custom Veristand project for new channels in the project. This destroys all the channels linking and creates pain when changing custom devices of County canal.

  I've created a good work around. I have create a VI that sweeps the current channels in the Veristand project against the list of channels in the compiled custom device. I then delete the items that don't belong, and add channels that do not exist. The net result is that only the channels that have been deleted to create bad links (obviously) and all the old links remain intact.

  I then create a menu right click on the home page of the personal device that runs the VI I created.

  The end result is a function that works just like the button "Refresh" on a model.

  I found the information that told me my customized window should run on android as well, but I can't figure out how to attach it.

  I see that you need to use the dps online app Builder to create your app for android (https://appbuilder.digitalpublishing.acrobat.com/#/main) instead of the application builder standard dps.

  In this app generator, I don't see any location to attach my zip custom showcase.

• Custom Viewer no synchronization of the iPad

  I passed through the process of creating custom together Viewer all the way up to the application being placed in my iTunes library. The application is built with the correct .p12 certificate and mobile configuration files as well. The custom Viewer appears under iPad Apps in iTunes, if the icon is not the Adobe Content Viewer icon, it's just the standard application icon. When I sync my iPad, the synchronization process runs normally, but the application does not install on my iPad. Everything has been updated to the latest version. Anyone know what could go wrong?

  Ugh, I feel like a silly billy. So it turns out that iTunes will ask you to allow synchronization of App... learn something new right every day?

• My devices synchronize with iTunes

  I can't understand why my iPhone more than 6 will not synchronize with iTunes.  It has been synchronized last last month.  I am currently with all updates

  Maybe because you just upgraded to iOS 9.3.2 (or iTunes 12.4)?  Just a guess.  In any case, this can help:

• Not truly Plug & Play with the generated for custom USB device .inf file

  Hello

  We have developed an application that uses the library OR-VISA-in order to communicate with our USB device via RAW communication.

  This is why we created an *.inf file using the driver Wizard. Once we plug-in the device for the first time, windows enumerates the device successfully and the 'Found new hardware' pop-up - window.

  We chose the .inf file that is created, and the device is properly installed.

  Our problem occurs when we plug one another device of the same type but with a different Serial-ID (which means that same VID, PID, only the ID for the USB - stick is different).

  For all devices with a Serial-ID, which has not been connected to windows, and yet, the "found new hardware" - window opens again so that you HAVE to choose the installation procedure. Despite the fact that the driver for this type of device was already installed, windows does not affect our driver .inf file to the device.

  If we chose, then in the "Found new hardware" procedure - the "Automatic Setup" window - the device is installed and can be used successfully.

  Of course, windows recognizes the right driver but does not automatically assign it without pop-up windows. We want to avoid the pop-up reapeating for each device.

  I did some research on this subject, and now I guess the problem is that the generated .inf file has no signature.

  Does anyone have experiences on this subject? Am I wrong? Does anyone have or had the same problem?

  All solutions next assign the same ID series for all devices?

  Here some quote the file setupapi.log (which seems to confirm my hypothesis):

  Hi Philip,

  Thanks a lot to post your question. I talked to our specialists in the United States on the signing of your created driver. You will find a brief description in the Readme of NI-VISA:

  "WHQL signature hardware USB.

  WHQL (Windows Hardware Quality Labs) sign your USB hardware using the driver NI-VISA for Windows XP / 2000, as part of this process it takes a PDB (program database) file to the underlying driver (NiViUsbK.sys).

  NiViUsbK.pdb is provided for this purpose. It is in \WinNT\NIvisa\USB. This is usually C:\VXIPNP\WinNT\NIvisa\USB. »

  To get it done, you must contact Microsoft. We are not allowed / able to sign your driver for you.

  Perhaps, the following link helps you: http://www.microsoft.com/whdc/winlogo/wlk/default.mspx

• Choose CPU Inline Custom Device

  Hello!

  I wonder if it is possible to assign a Custom inline device to a specific processor. I know it's possible to do a custom asynchronous device.

  I developed a custom device inline, calling an asynchronous vi. I can affect the heart for the asynchronous part, but how to choose the kernel for the part online?

  Thank you...

  Hello, I guess that the online part is executed from the thread VeriStand, then the kernel is involved by the call control loop and cannot be changed. But maybe I'm wrong?

• Customized for the RT FIFO device details

  Hello

  I have a few questions about the FIFO VeriStand in a custom device asyncrounous.

  I saw a post earlier where a - 1 to the function of reading of FIFO of RT for him to wait indefinitely for an item to enter the FIFO. This allows pseudo - synchronize the PCL with a device custom asyncrounous. I wonder if this causes the boundary wire custom sleep or it stay active and keep returning? Is it possible to change the polling to blocking?

  Another quick question, if I only want to write to the RT FIFO when the data has changed it will cause unforeseen problems? As the channels time or need to wake up or something? Certain conditions can only write channels once every 1000 iterations of the PCL and loop device custom.

  I know that I can not write the channels selected in a FIFO RT, but can I create multiple FIFOs in a custom device to actually do the same thing? I imagine then having the outputs 1, outputs etc 2 in VeriStand.

  Thank you

  B

  Hi B,

  If you look at the RT VI pilot generated from custom device model you will see exactly what is happening. If you set the time-out for the reading of FIFO-1 then the botton loop will be essentially suspended unless there are items to read in the FIFO. Meanwhile, the thread will always be active because the RT read that VI is querying data during the time specified in the timeout.  I don't think that there is a way to change the FIFO mode to blocking since the dismissal of the FIFO is spent Veristand engine to the RT VI driver.

  

  The PCL writes and reads data from and to asynchronous custom FIFO device at each step of the execution. In your custom device, you can configure to read and process data of the 1000th step. I don't see any problems with it.

  You can have a FIFO for input channels and a FIFO for the output channels. You can write to an output channel given by writing data in a function index element in the output array that is passed to the function RT FIFO Write.

• Multi-threaded custom device

  Is it possible to create a custom multithreaded device?  I want to create a client-server architecture, somewhat like the http://zone.ni.com/devzone/cda/tut/p/id/3098 example in a custom device.  The only difference would be that I would like to make the series of read/write in the high priority task.

  Thanks for the help!

  -Ryan

  Hi Ryan,

  This should be possible if you use a custom asynchronous device. The curls will then run in their own thread and do not affect the execution of the primary control loop. Make sure that there is enough time sleeping in your loop of high priority. Note, however, that put communication series in the loop of high priority will negatively affect your determinism.

  For more information on the Veristand engine and the custom device types you can choose one, please see the following:
