• 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

  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.

• The list of custom device alias

  Hi all

  I'm trying to retrieve the list of aliases of a custom device and generate a file containing the list of aliases and the reference of the chain. I wanted to do before the depoyment of my device custom (for example, during the initialization stage). I have tried different means:

  (1) from the driver of the RT, I get the reference of the target and navigate the tree of thr to get the aliases Section. The problem is, apparently, that you can not get the aliases section. When I call get target Ref, I received the mention of the controller, and then I managed to get the parent (targets)... but I can't get the root node, and then get the alias Section...

  (2) after that that I wanted to use the API to run. I opened a connection to the workspace, call the list of aliases to Vi... But the problem is when I'm in the my custom device initialization stage, it is not started yet, so it returns an error and that you can not deploy

  (3) my last idea was to use the systemDefinitionAPI. But I don't know how to get the path to the custom device system definition file...

  I think that I have run out of idea... If anyone has a suggestion...

  There is a function on the system definition API you can call directly to translate a reference device custom in the definition corresponding system API node type. This type of node, you can navigate to the root and then find all defined aliases.

  The class is called NodeIDUtil. See the example below. Note there is also some other functions to translate the reference point in node types more specific, as a custom device, channels, etc., waveforms. For example, recorded in 2012.

• Custom device error VeriStand-307603: no specified main page?

  I get the 307603 error when I try to add a custom device, I developed a VeriStand project on a client computer.  The message error window States:

  «Error 307603 occurred at Custom Devices Storage.lvlib:Initialize New Custom Device.vi > Custom Devices Main Page Data.vi Storage.lvlib:Get.»

  Possible reasons: NI VeriStand: the required custom device doesn't have a specified master page. Contact the creator of custom feature to correct the error. »

  I get this error when you add the device custom VeriStand on my development computer; only on the client computer.  I tried to copy the custom device built on top of the client computer and the custom device of source based on the customer's computer.  I also have three other devices custom that I developed that work fine on the same computer, so I don't know why it does not work.  I checked the specification of the build configuration to ensure that the VI home page is included in the source files, and to generate test preview shows only the custom device LLB and the XML from the file in the build directory, as expected.  The XML file is also oriented the correct path for the homepage VI and the GUID in the XML is the GUID file matches in overall search GUID variable.  I can't think of anything to check.

  Development computer:

  Windows 7, 64-bit

  LabVIEW 2011 SP1

  VeriStand 2011 SP1

  The client computer:

  Windows XP SP3, 32-bit

  LabVIEW 2011 SP1

  VeriStand 2011 SP1

  Everybody knows such a question or give me additional troubleshooting tips?

  I got it to work, but I don't know exactly what the problem was.  I made a copy of the part of the XML file that adds the device custom menu right-click and commented of the original, then edited the part I copied it to give the device custom a different name in the menu.  It worked fine on my development computer at the time I made the change, so I thought it was OK.  I just went and restored the file in the original version and now it works on my customer's computer.

• Rename a custom device

  Hi all

  I made a custom device that perform some operations with the associated DAQ card.

  In the Solution Explorer system Veristand, to manage several boards, it is possible to add multiple instances of it. The name of each instance must match the associated with a DAQ card, he is asked once and is never changes (in the camera custom XML file, I added the entry 'true').

  Demand for the name is made just after the addition of the instance in the tree Explorer (right click on the entry "Custom devices") system. In particular, the name is invited to call a VI that I put in the "Initialization.VI" of the library of device configuration custom. Unfortunately, this approach I am not able to change the name because ot the property of DisallowRenaming and an error is raised.

  How can I work around this problem? Is there an event as described in the "Custom Device" Guide (OnDelete, OnLoad,...) which can be pulled before the call of the "Initialization.VI", but after the addition of the instance in the system Explorer tree?

  Thank you

  aRCo

  I recommend to remove this label of your item custom main device. its best practice to rename the custom feature set.

  In addition, you can store the name of the physical device as a separate property rather than use the custom device node name.

  Finally, in 2012, we have added a "force rename" bool entry to the item to rename API to work around this problem.

• Satellite A100 CD/DVD drive is not listed in the BIOS or Device Manager

  1. the original drive does not work. After inserting a disc shines the light of the drive and it runs - but nothing else.
  A little investigation shows no optical drive listed in the BIOS or Device Manager (naturally).

  2. perhaps I would reinsert the disc, but I can't find any instructions on internet about this disc removal/replacement.
  Or in the operating manual.

  Can someone direct me to these instructions?

  Thank you very much

  S manual is not the same thing as maintenance manuals. Please note that this is not the same and the exact description on laptop procedure disassembly is only authorized service.

  Anyway, as far as I know the optical disk drive is fixed with a screw and it can be removed from the underside. The screw is placed near the cover of exact memory on the optical drive. Not on side cooling event, but on the other side.

  Be careful because everything you do is at your own risk.

• I have problems with of the Subvi after the use of customized device model

  I used to start my machine personalized customized device model and I got success in the deployment until I started to do more complicated the Subvi.   I am currently trying to convert low FPGA and high ticks to the duty cycle, but for some reason when I add it to the RT VI "Data read of HW" driver, it seems to cause a downtime... ideas? Is a circuit agree? I have added a time delay but I am still having problems. It is a device online, so I'm suspicious of it hogging resources, but am not sure.

  Attached images are meant to be read like this:

  1. the case of the RT pilot ReadDataFromHW

  2. it's the Subvi calling ToDutyCycle SIMStimPWMSubVI

  3 ShiftRegister.PNG is inside the Subvi.

  As a robotician I celebrate early and often (usually by a failure or two...), but it seems that the answer was to transform fundamentally the While loop for a loop with a count of 1 and then remove the additional elements to ensure that each shift register has that one and then right click on the shift registers and convert at the Feedback node...
  I was able to deploy to VeriStand as a custom device and it runs and calculates the factor of use with no problems. WOOHOO! Where - what is celebrate button!

• Read VeriStand channel from inside the custom device that are not part of the custom device?

  Is it possible to read VeriStand channels from within a custom device VeriStand (RT Driver) that are not part of this custom device?

  For example, suppose I want to be able to configure a channel in my custom device to always be twice the value of a string of material that my user selects (I know, better/more simple ways to do this, but this is just a simple example ).  Can I do this from the device custom without programmatically create a mapping of the system? (I've done this before and it is messy and VERY prone to error of the user).

  Thank you!

  good point

  the channel ID (U64s) are not the same in the engine config of vs. Instead, you must set 'references to dependent item' in the config and then get these references in the engine.

• Best way to pass the name of the e/s DAQmx channel Veristand 2011 Custom Device?

  I'm building a custom device that will run a DAQmx task on the target of RT.

  I use VS2011 and alsoSimple custom device tool, which, at this point I'm not sure if it can work under VS2011...

  I created the fine libraries and custom device (a PWM input called InputPWM) has added to the Explorer from the system.  Running it returns the following error when I deploy:

  -----------

  LabVIEW: Type VI reference is not part of connector of VI.
  =========================
  NEITHER VeriStand: Open VI reference in Custom Devices Storage.lvlib-> pen device reference (Interface HW) .vi-> Custom Devices Storage.lvlib:Initialize Device (Interface HW) .vi OR VeriStand Engine.lvlib:Initialize Inline Custom Devices.vi-> NI VeriStand Engine.lvlib:VeriStand Machine.vi engine-> Engine.vi NI VeriStand Engine.lvlib:VeriStand-> NI VeriStand Engine.lvlib:VeriStand .vi engine Wrapper (RT)
  c:\NI-rt\VeriStand\Custom Devices\InputPWM\InputPWM Engine.llb\InputPWM RT pilot VI.vi

  ----------------------

  On the console, it says that the error is 1026, LabVIEW: Refernece VI is not valid.

  I suspect that a potential problem is that I used a DAQmx e/s in the Configuration.ctl and the InputPWM RT pilot VI.vi in the framework can not deal with this type. So my questions:

  -What is the easiest way to pass the names of e/s to the custom device? For a quick test, I could go to hard code, but a more generic solution would also. Should be based on the address for the e/s MAX? Do I have to create the ctr under the DAQ hardware in VS?

  - or said by the way, is there a way to review these screw frame to see where the questions is, as you would with LV - RT?

  THX.

  L.

  If you use the tool of easy custom device, just put everything you need inside the cluster configuration data and these data will be in the home page of the custom (for the user to set) device and be available at runtime in the RT device custom code.

  You could have them type the name of the DAQ card and have an array of names for the channels to use. You then create the task running. or something like that. You like.

• Downloaded new itunes now iPod not recognized. Uninstalled and reinstalled. No sign of the driver on the list of devices iPod win 10. Tried the other fixes - what do I do now?

  With the help of Windows 10. Downloaded latest version of iTunes (should have been better). Now iPod Nano not recognized. Tried to uninstall and reinstall iTunes without result. Check the list of device driver - no sign of the iPod device driver. Read various tips listed here, but nothing seems to work. How can I get the driver?

  The 'driver' is here.  It is part of the installation of iTunes.  When you connect it, the iPod screen indicates it is connected, by showing 'do not disconnect' or 'Connected' or another indication that there is a data connection with the computer?  If it shows that the battery symbol, there may be another problem that requires no software and 'drivers '.

  If the iPod has a data connection (but he does not appear in iTunes), you can use the procedure to completely uninstall iTunes and associated software components.  Can you only uninstall iTunes.  It's the Apple procedure, listing the components uninstall and uninstall specific order

  I have not installed anything new, so I am confused as what to do :/

  Hello

  It looks like the driver for the touchpad stopped working.
  I have no idea why, but I recommend that you install the driver once more.

  Visit the page of the Toshiba UE driver.
  Select your notebook series and download the touchpad driver.
  Then unzip the driver package and install the driver.
  Reboot the laptop and test again.
