Labview NXT 2013

In the 2013 version of Labview for NXT some of the vi's such as Steering On no longer work with our NXT lego brick and motors. In addtion the motor Drive Distance Vi that turns a motor a specified distance works unpredictably. Are these Vis not working for anyone else?
Finally, is there a way to calibrate the Polysensor when used for Light Sensing? In a previous version of Labview there was a Calibrate Vi that could nicely be used to calibrate the light sensor for the old NXT_LightSensor vi . This calibrate vi does not work with the Polysensor configured for use with the Light Sensor. Without being able to calibrate the Polysensor the contrast is limited to output values of about 40 to 60 instead of 0 to 100.
This semester my students were highly frustrated with the performance of the 2013 Labview for NXT vis. As stated above several didn't work at all and some worked in highly unpredictable ways. Are there bugs in the Labview for NXT 2013 module or is Labview for NXT now optimized for the EV3? If this is the case will I have to replace all 46 of my NXT bricks with EV3's if I want to continue to program them with Labview?

Assuming it is optimized for the EV3, which I would expect is a good guess, why would you need to upgrade anything? The easiest fix would be to revert back to the software that was working well for you. It'd also be the cheapest solution.

LabVIEW NXT toolkit and Vista

Hi All,
This is not a burning problem, but have folks tried out the NXT toolkit with Vista? I've installed Vista Business Edition under our MSDNAA license on a development machine to start slogging through compatability issues with our current suite of software, and it appears the LabVIEW NXT toolkit may be an early casualty.
The toolkit installs fine under Vista BusEd, but the NXT console application crashes when I try to run it from the LabVIEW IDE menu.
Any thoughts/experiences with this?
Best regards,
-Bill =]

Hi Joel,
Thanks for your reply. The specifics of my development system are below:
OS: Windows Vista Business
Proc: Intel Pentium 4 CPU 2.80 GHZ
RAM: 1014 MB
Type: 32-bit OS
I chose to use the Vista UPGRADE of WinXPsp2 rather than a wipe and clean install. Before upgrading the OS I removed all previous versions of LabVIEW (7.1 and 8.0) and also removed the Mindstorms NXT-G system.
After the OS upgrade to 32-bit VistaBusEd, I installed LabVIEW 8.20, then Mindstorms NXT-G, several LabVIEW Toolkits and finally the LabVIEW NXT Toolkit.
When I try to load LabVIEW code that uses (for example) the sendDirectCommand.vi from the FantomSDK, I get the following block diagram error:
"Call Library Function Node 'fantom.dll:nFANTOM100_iNXT_sendDirectCommand': function not found in library
Details: The function name specified for this node cannot be found in the library. Right-click the Call Library Function node and select Configure, then choose the correct function name.
When I follow the Details procedure, I specify the exact location of the fantom.dll, select nFANTOM100_iNXT_sendDirectCommand from the Function name dropdown listbox, the Thread is set to Reentrant and the Calling convention is set to "C".........after closing the dialog I get:
Error loading "C:\.....path.....\fantom.dll".
A dynamic link library (DLL) initialization routine failed.
Also, when I create a blank vi and drop a function from the LabVIEW NXT toolkit, such as NXTToolkit.DC.FindNXT.vi on the block diagram, I imediately get the following similar error:
Error loading "fantom.dll".
A dynamic line library (DLL) initialization routine failed.
Does this help?
Many thanks,
-Bill =]
p.s. - BTW, the Minstorms NXT-G system works as expected under the 32-bit VistaBusEd using both USB and Bluetooth.....so I guess VistaBusEd is able to intialize and communicate through the fantom.dll when used by NXT-G.

Count number pixcel labview vision 2013

hi gays
i need your help i want to count number of pixel with template in labview vison 2013
thanks
Solved!
Go to Solution.

Try the VI IMAQ Count Objects 2 in the Vision And Motion>Machine Vision>Count and Measure Objects palette.
If that does not do exactly what you want, you can still choose to migrate the VBAI inspection to LabVIEW (Tools>>Migrate Inspection to LabVIEW from VBAI) and look at the code generated. It will produce exactly the same results as in VBAI. The only thing is that the code generated is complex.
Hope this helps.

Count pixels labview vision 2013

hi
i want to determined percentage of pixels in a region, like function count pixcels in NI Vision Builder AI but in labview vision 2013

Brad, thanks for the response. I don't have access to the code anymore, I was more just curious about it. One of my old coworkers has actualy been in contact with me recently because he's the one who inherited my code. I had to walk him through how I implemented the VBAI code in to the main application because he couldn't just change a few setting inputs. It was more of just a inconvenience.
I guess my suggestion for the future would be for an option to output the VBAI code as LabVIEW code without all of the subVI hierarchy for those who are used to just using the IMAQ VIs. Just a linear set of code that goes from the start to fnish of the VBAI diagram that I could manipulate the way I want would be nice.

Labview myRIO 2013 stopped working after product activation, system vi files not found, (Hex 0x8004041F)

Hello,
My Labview myRIO 2013 had been working while it was in its evaluation period. Recently, I activated Labview 2013 with a 6-month activation code. Now, if I try and create the standard myRIO tutorial starting project, when it tries to load "Main.vi", it stops and says:
Loading:
<vilib>:\myRio\Common\Instrument Driver Framework\myRio v1.0\myRIO v1.0 Reset FPGA.vi
Searching:
C:\Prog... \LabVIEW 2013\Targets\instr.lib
and it pops up a file browser dialog box.
I found the file in C:\Program Files (x86)\LabVIEW 2013\vi.lib\... , so I manually added that path to Labview's VI search paths, closed everything, and re-opened Main.vi .
After doing so, I can get Main.vi to load and display properly after taking it's dear sweet time to recursively search vi.lib\* for each vi file, but if I try to run it, I get a crytic and un-googlable error message:
NI System Configuration: (Hex 0x8004041F) The operation failed because of missing dependency items.
It gives no further information on what dependency items are missing.
Why did Labview work before? It had no problem finding dependency vi files before I activated the product. The "Getting Started" demo apps still work fine, reading accelerometer data and controlling the led's on the myRIO, so I know the myRIO itself is working, along with the USB connection.
One final note, the "Labview 2013 Real-Time Module" has not been activated. Could that be the problem?

Hi Mike,
That Hex error message only occured if I tried to run the VI by clicking on the little "run" button at the top left. Main.vi would open just fine, after locating all of the vi files.
So I seemed to have fixed my particular issue (for now)... I had noticed after I typed in my activation code that Labview was telling me that I had additional evaluation time available to me. I had been ignoring those messages because, 1. I had an activation code and therefore didn't need additional evaluation time, and 2. Labview was opening and appeared to be running just fine, whereas before I applied the activation code, Labview would not even start. So, towards the end of my adventure after I felt I had applied my forehead to my keyboard a sufficient amount, I finally said "Ok whatever, give me additional evaluation time", and voila, all of my previous issues disappeared. Vi files were being found normally as before, and I was no longer getting that Hex error when I hit the run button.
I'm not sure exactly what components I'm getting "additional evaluation time" for, but whatever component it is, it seems to have fixed my problems.
So anyway, thanks for the support! Hopefully this fixes my problem for good

LabVIEW Toolkit for LEGO MINDSTORMS NXT in Windows Vista

Anybody knows how install LabVIEW Toolkit for LEGO MINDSTORMS NXT with Windows Vista?. Installing it gives me an error that says 'The windows installer is corrupt. To attempt to resolve the issue, please register the engine by running regsvr32.exe on msi.dll'. But it doesn´t work.
Thanks in advance

The work around for this issue is to install each of the MSI files setup.exe calls when running the installer. I was able to reproduce this issue for the 1.0 toolkit I was unable to do so for the 2.0 toolkit. This being said the instructions bellow are for those of you who are running into this issue with the 2.0 toolkit.
Listed bellow are the MSIs you will need to run (shown here at their default location after the self extracting EXE has been run). You should run these MSI in the following order.
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\MetaUninstaller\MU\MetaUninstaller.msi
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\MDFSupport\MDF\MDFSupport.msi
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\MDFSupport\MDF\EULADepot.msi
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\LVLEGONXTTK\LVLEGONXTTK\LVLEGONXTTK.msi
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\LVLEGONXTTK_LV71\LVLEGONXTTK_LV71\LVLEGONXTTK_LV71.msi
C:\National Instruments Downloads\LabVIEW\7.1\LabVIEW NXT Toolkit\2.0\Products\NXT_Driver64\LegoMindstormsNXTdriver64.msi
A similar procedure can be used to install the 1.0 toolkit if need be. You can get the install order from the parts from the [Parts] section of the setup.ini.

When will LabVIEW Drop Support for the NXT?

We currently use LabVIEW to program LEGO NXT kits in our engineering courses. However, LEGO is phasing out the NXT within the next year or two. Does anyone know the LabVIEW/NXT life cycle plan, i.e., when will LabVIEW no longer support the NXT platform?

Hi Joel777,
NI doesn't currently have a definitive roadmap for future NXT support in LabVIEW, but I recommend you check out the community page for updated modules. I would also recommend adding any feedback you have regarding future releases to this page in the comments section and periodically checking this page for support updates.

I do know of this one software where you can simulate the NXT, but it might only be for NXT-G programs.
SimplySim at The NXT Step
Other than that I don't think there's any way.
As for the difference between the two, there's a whole ton. Those are two different programs with very different syntaxes. Lego NXT-G is the basic software that comes with the NXT kit. It's a very scaled down version of LabVIEW and is pretty nice. LabVIEW is much more advanced and you can do much more with it, but you are restricted to using the LabVIEW NXT Toolkit and the NXT's cababilities. (no float, only so much RAM, etc.). But you can still do a ton more with it. Yes, you can data log with LabVIEW in, like, many ways.
Hope that helps!

When replacing Labview 2013 with Labview 2014, do I firstly need to uninstall Labview 2013?

I have just recieved my latest version Labview 2014 CD.
When installing this new version, do I firstly need to uninstall previous Labview versions?

The reverse, however, is not true. Once you install one version of LabVIEW, you cannot install an older version without uninstalling everything and "starting over". Be warned ...
Not exactly true. You can install just an older version of LabVIEW. I have had LabVIEW 2012, 2013, and 2014 installed on a computer and then installed 8.2.1. It is all of the support drivers and what not that do not install side-by-side. So the real lesson here is that if you install an older version of LabVIEW, pray that your current drivers support that version of LabVIEW. You will need to reinstall the drivers to install the support for the older version of LabVIEW though. Installing just the support takes hardly any time.

Uninstall of LabVIEW Student Edition 2013 on Mac

I recently installed LabVIEW SE 2013 on MacOS 10.9.2. My goal is a working install of ROBOLAB for LabVIEW which is currently not working properly. My next idea is a complete uninstall and careful reinstall of required software.
The NI resources on the subject of uninstallation recommend using the uninstall.sh file on the install media to complete an uninstallation. My install media was a downloaded .mpkg file that includes neither an uninstall.sh file or an uninstall option in the installer. Any advice on how to proceed with a complete uninstall?
With the exception of the driver packages, can I assume that all the LabVIEW files end up in /Applications/National Instruments or are there other locations that end up with LabVIEW files in them?
Solved!
Go to Solution.

According to this KnowledgeBase article the Uninstall script should be in the Extras folder. I have attached the file from my LV 2013 for Mac disk.
There are quite a few files in Library/Application Support and Library/Receipts as well as Applications.

"Small Font" in LabVIEW 2013/2012 Icon Editor

Dear All:
I have encountered a strange thing recently while using icon editor in LabVIEW 2012 and 2013. I am accustomed to using "Small Font" when editting VI's icon in the Icon editor(LabVIEW 8.0,8.2,8.6,2011), but i found this font in LabVIEW 2012/2013 is different from the one in LabVIEW2011(or 8.6..), the details are as attached images. My question is how can I do to use "Small Font" as I did in LabVIEW 2011, and how to remove the color layers while editting text. any help will be great appreciated. Thanks very much. Hope your reply……

Then do the settings, choose right FONT (Small) and Font size (8 or 9)...!! By doing any changes in the settings, it will not modify any existing text..!!
But after making the changes in the Font setting, next time when you'll try to write any text, either on any of the four lines or by using the text tool, you'll see the text with changed font settings.
I am not allergic to Kudos, in fact I love Kudos.
