So, now that we've gotten that out of the way, you probably want ideas on how to make this work

I suggest that you need to get the image data out of memory and stream that across the network. You're going to need to convert the data to a string, and depending on the resolution and colour depth of your image, that could be a lot o' data and could take some time to get across the network. There's a VI floating around somewhere that convert the data to a jpg string with compression directly from an IMAQ reference - have a dig around on the net...

If you get stuck, post again - I'm a little flat-out at the moment, otherwise I'd try to dig up a solution for you...]]> Sat, 06 Sep 2008 23:58:46 -0500 crelf z3r0 c0o1 crelf USB webcam over LAN problem

Ok, here is what I have done.

I have successfully installed the IMAQUSB drivers and they are working great with my Logitech webcam. Now I have created two separate vis as a client and server to send the video input from the cam over LAN using UDP. I first tested the two programs on a same PC sending the data to localhost and its working great, the image is displayed and the indicator of bytes received is going up

as it should.

And now the problem:

The problem happened when I placed the two programs on separate pcs connected over LAN. On both pcs there is an identical set of software from LabView with the drivers running on XP Pro SP2. The two vis are working ok, the firs pc is sending the image and the second should display the image, but it doesn't

. The indicator for the bytes received on the second pc is going up indicating that the two vis are communicating but there is no picture. Also the probe at the UDP data output is indicating "image0" saying that the image is coming except the image display is not showing anything.

After this I tried to broadcast the image over lan and again the same thing, on the localhost there is an image and on the remote pc there is no image, but the number of bytes received is going up.

If anyone has any idea about this problem or has an example vi for transmitting webcam video over lan ill appreciate it

Thanks

QUOTE (HChandler @ Sep 5 2008, 08:58 AM) <{POST_SNAPBACK}>

Well. the part I'm mad at them for is not giving the developer more control of what gets linked to what.

You have all the control you need. But like Yair said, the problem stems (mostly) from the fact that LabVIEW can't simultaneously have 2 VIs in memory with the same (qualified) name. This takes some getting used to, but honestly, for the most part you're feeling helpless right now because you don't yet know how to use the tools that are in front of you. Everyone goes through that at some point, with every new language.

QUOTE

Admittedly, I'm a babe in the woods when it comes to LV development, and I should have laid a better foundation. Still, I would much rather deal with a Makefile than the interminable dialogs and "stuff being done because it was programmed that way by someone who's assumed (and you know what that means) that everyone is on the same page with regard to programming style.

And I would much rather deal with LabVIEW's project windows, VI hierarchy, and linking behaviors than cryptic Makefiles and 10 pages of compiler warnings/errors. It's all a function of what toolset you're used to working with, and the discomfort you feel when you move to a different workbench.

QUOTE

Or should I say styles. Like everything in labview, I've got a million ways to screw myself over. I've got the project, llbs, lvibs, all of that OO stuff, project folders (auto populating and virtual). I have very little determinism. Too much gets done for you, and in ways that you might not want to have happen.

Actually, it's generally very deterministic. Unless you're misusing the word?

That having been said, I can sympathize with you. LabVIEW is pretty aggressive about the way it tries to resolve subVI linkages, and even though the dialogs and warnings you get are a lot more helpful than they used to be (there was a time when there were no cross-linking messages -- it just happened invisibly!), as a novice user it's hard to understand when you've gotten yourself into a ditch until you've driven several miles in it.]]> Sat, 06 Sep 2008 15:08:59 -0500 Justin Goeres HChandler Justin Goeres <![CDATA[Setting up reusable vi's without crosslinking woes]]>

QUOTE (HChandler @ Sep 5 2008, 07:58 PM) <{POST_SNAPBACK}>

Why can't I turn off automatic linking!

Because a) the code has to be in memory to be compiled, b) it has to be loaded from somewhere and c) you can only have one VI in memory with a given name.

If you turned it off, LabVIEW would not be able to do its edit time compiling which it currently does and would be not be able to perform all kinds of optimizations it currently does. My understanding was the whole concept of libraries in LV 8.x was to avoid the cross linking problem.

QUOTE

Why can't I explicitly (and exclusively) specify what to link to and what to compile?

You sort of can. If you open a VI from disk and then open a hierarchy calling another VI with the same name your first VI will be loaded. Of course, the practicality of that for multiple VIs is limited.

Should NI have a dialog which will allow you to manually resolve cross linking issues across your entire hierarchy? Maybe, I don't know. You should submit a product suggestion in NI's product suggestion center.

Maybe a dialog like that can be written today, but the first option I'm thinking of will not work, becuase LV will not let you open a reference to a VI on disk with the same name as a VI currently in memory. I believe there is a private method for replacing a VI with another in code, but I'm not sure how it would behave. The only solution might be to keep a list and then close the hierarchy, open the VIs in the list and then open the hierarchy again.

While that method is reasonably likely to work (at least in Windows), it fails to account for many corner cases (e.g. non-Windows OS, a VI in an LLB, a VI whose extension is .exe, etc.). A more robust way would be to do something like this:

QUOTE (Jon Sjöstedt @ Sep 3 2008, 03:39 AM) <{POST_SNAPBACK}>

Hello all!

In order to not jeopardize concurrent access to a file, I have made some tests with the "deny mode" wire to the "open file" vi. It seems to work (I am using lv 7.1.1 on Solaris). I do accesses from different hosts that map the same NFS partitions. Looking at the file properties during execution of the tests, no permissions are altered. Neither can I see that any kind of lock file is created. I have also noticed the the file is only locked for labview. I can access the file perfectly with emacs or cat.

My question is therefore: How is this "deny mode" functionality implemented in solaris? I dont want to break it unintentionally.

Not sure about Solaris really and Solaris in many ways is often a bit special. But on Linux it seems to be implemented by range locking the entire file.

I also had to do that to control a stepper motor to change wavelengths on a fluorometer, but I was using a DAQ card (USB-6009), not a PCI card. I don't know how to do it with a PCI card, but here's how to do it with a DAQ card. I'm not sure what your stepper motor inputs are, so you should first get the manual that tells you what each of the inputs do and what voltage they require. For instance, the machine I was using was very old, so we had to cut open the cable and trace each individual wire back to the input on the stepper motor. The manual told us what each pin did (e.g. change direction, step, etc.). The change direction and step should probably be digital inputs. For instance, on my stepper motor, each time you input 0V and then +5V, the motor would step.

Alright, so plug wires connecting the input pins to your stepper motor to the DAQ card. The DAQ card contains pins for digital i/o, analog output, and analog input. So for those inputs requiring digital signals (0/+5V), I plug it into those, and for those that require analog inputs, I wire it to the analog output of the DAQ card. From there, I controlled what I wrote to the inputs of the DAQ card using functions in the NI Measurements>>NI-DAQ MX subpalette. There's lots of examples installed in Labview relating to writing to a DAQ card.

Hopefully that helped a little bit,

TCP IPv6 Tools for LabVIEW Version 1.0.0

Mark E. Smith
Sandia National Laboratories
mesmith@sandia.gov

LabVIEW does not support IPv6 protocol (as of version 8.6) using the TCP/IP functions and there is no promised date for inclusion of IPv6 compatibility in an upcoming version. I have a project that requires IPv6 TCP communication so I requested that NI support my efforts which they graciously agreed to do. Christian Loew of NI created a proof-of-concept project using Microsoft Visual C++ to create a DLL that provided LabVIEW access (through a Call Library node) to Winsock 2.x. I have taken that proof-of-concept project and refined it into, as much as practical, a direct drop-in replacement for the TCP/IP functions in LabVIEW.

Features:

- Drop in replacement for native LabVIEW TCP/IP functions

- Supports IPv4 and IPv6

- Compiled and tested for LV version 8.5, 8.0, and 7.1

Limitations:

- Does not support name/service lookups – the user must supply a valid network address in dot-quad (IPv4) or colon-delimited hex (IPv6) – the loop back addresses of 127.0.0.1 and ::1 are acceptable

- Only supports the Standard and Immediate modes for the TCP Read function. The Buffered and CRLF modes could be added (I just have no present need)

- Windows only – uses the Winsock 2.x DLL. However, the only Winsock-specific functions called are WSAStartup (to initialize the DLL) and WSACleanup (to release resources). Everything else should be portable to a sockets implementation on Linux or MacOS (this is speculation only!) if anyone has a need.

This package includes:

The Winsock wrapper DLL (lvipv6comm.dll)

Example VIs – Data Client.vi and Data Server.vi are adaptations of the example VIs of the same name that ship with LabVIEW that use the IPv6 Tools instead of the native LabVIEW TCP/IP functions

For LabVIEW 8.0 and 8.5, a LabVIEW project exists (TCPIPv6.lvproj) and the TCP function VIs are in a LabVIEW library (TCPIPv6 Comm.lvlib). For LabVIEW 7.1, the TCP function VIs are in a single folder.

specific question:

i am using an airpcap packet sniffer where my c# app uses the airpcap.dll unmanaged driver to build the dllimport primarily for automated control of changing wifi sniffing channels from labview. although the data marshalling looks correct, i'm having problems with error code number 1172; System.AccessViolationException; attempted to read/write protected memory. this must be one of those times since i am accessing an unmanaged driver, i must reserve memory for the variables in c#.

However, once in a while, the V200 board will disappear from MAX when we run the Resource manager. Then sometimes it will think it's made by another manufacture (AMP, Inc.) then will disappear on the next run of Resource Manager.

if you have a theory, does it fit the following definition of theory within a scientific sense? Or is it just conjuncture and speculation?

QUOTE (Wikipedia)

In science a theory is a testable model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise verified through empirical observation. For the scientist, "theory" is not in any way an antonym of "fact". For example, it is a fact that an apple dropped on earth has been observed to fall towards the center of the planet, and the theories commonly used to describe and explain this behavior are Newton's theory of universal gravitation (see also gravitation), and the general theory of relativity.

In common usage, the word theory is often used to signify a conjecture, an opinion, a speculation, or a hypothesis. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality. True descriptions of reality are more reflectively understood as statements which would be true independently of what people think about them.

A scientific theory must be falsifiable. There must be a defined set of circumstances which could be practically used to prove a theory false or true. What would this look like in your case?

When you get the path of a VI from within an EXE, the name of the EXE is treated as a folder. The EXE is basically just a glorified LLB.

You need to strip one extra level from the "this VI's Path" to get the containing folder after making an EXE. Pain in the rear I know, but once you know about it, you'll know in future.

The ideal candidate would be a self-starter who can be given a task & deadline, and independently develop an elegant solution with minimal supervision. An ability to rapidly learn/come up to speed as evidenced by knowledge of current technologies and skills is a big plus. This position involves creating real-world devices for the manufacturing environment, so the ability to "roll up one's sleeves" and actually take a concept through design, building, testing and convert it into a real-life functioning product is paramount. Very few jobs offer the ability to utilize such a broad range of skill sets simultaneously, and that is a major advantage to working at Tesla Motors, as it is never boring.

We are looking for someone with demonstrated experience to develop and maintain Manufacturing Test equipment software in LabVIEW and TestStand. You will help support the existing LabVIEW systems, refactoring code as necessary for improvements and maintainability as well as develop new software for new testers. New projects are expected to start with a Requirements Specification document, use source control (subversion), and set up code reviews with fellow LabVIEW programmers. No hacks allowed.

Units under test range from PCB assemblies to larger electronic and electromechanical system assemblies such as the Battery, Power Electronics Module, motor, vehicle electronics, or even the whole car. You will work with product design, design verification test, manufacturing, and manufacturing test engineers to gather requirements enabling you to design, develop, document, fabricate and deploy your test equipment. The test equipment often involves high voltages and/or currents, and must be safe and easy to operate. Multiple copies of each tester will be produced, so documentation and design for reproducibility and easy maintenance is a necessary habit. The test equipment can involve many channels of analog and digital I/O signals, custom interface electronics, cabling, rugged fixturing, robust packaging, and automation software that is operated by factory technicians in a 24/7 factory environment. Experience developing robust software is essential. GUIs must be easy to understand and behave as expected to untrained users.

Minimum Requirements:

B.S. or M.S. in Computer Science, Electrical Engineering or equivalent
Proven ability to collaborate on small technical teams
Expert skills with National Instruments LabVIEW (CLA or CLD certification a plus)
Demonstrated experience with GOOP and LVOOP
Demonstrated expertise developing coherent GUIs in LabVIEW
Experience with designing production test and test equipment control code
Knowledge of Design For Manufacturability & Design For Testability principles
Excellent communication and project documentation skills
Knowledge of New Product Introduction (NPI) and Product Lifecycle (PLC) processes

Experience with TestStand
Experience in .NET, Visual Basic, Visual C++/#

QUOTE (JiMM @ Sep 3 2008, 06:39 PM) <{POST_SNAPBACK}>

My kids rented Mario Kart wii last week, and it was really cool racing against people around the world. One of my kids spent hours trying to set a world record on one of the courses. That's one Christmas present picked out!

I just bought Mario Kart Wii a few weeks ago. For anyone who was a world-class expert at Mario Kart for the N64, you may find some of the differences beween N64 and Wii to be a bit annoying. For example, you can lose powerups that you're holding onto if you fall off a ledge, get hit by an opponent with star power, etc. Also, power-sliding (now called 'mini-turbo') has lost a lot of its subtlety, which is a shame for those of us who perfected it on N64. They made the off-road areas (grass, mud, etc.) slow down your vehicle a LOT more than in N64...for example, there was a shortcut at the end of the DK Jungle route where you could bypass the inside cave by power sliding directly across the cave through the thicker dirt...this shortcut (and many others) has been neutered on the Wii. I believe they tried to compensate for this by making mushrooms give you a much bigger thrust...but since you can very easily lose mushrooms you've been saving, I don't think it's enough compensation.

All that being said, the game is still awesome. There are twice as many tracks on the Wii as for N64 (although many of the Wii tracks are retooled versions of Mario Kart tracks from SNES, GBA, N64, GameCube, etc.). The races also have 12 players now instead of 8. I really like the addition of racing bikes...in fact, my favorite vehicle in Mario Kart Wii is the Bullet Bike, which has a super-tight turning circle...very helpful on some of the very wind-y Wii courses.

Being able to play people online is a major plus. Unfortunately, all the badasses online already know all the super-fast shortcuts on all the routes, and I haven't taken the time to figure all of them out.

There are several ways to drive your vehicle. One is to hold the Wiimote sideways (or insert it into the 'wheel') and use the Wiimote like a steering wheel. Another is to hook up the Nunchuk and use its joystick. Still another is to use the Wii classic controller. I have tried all 3 methods, and I prefer the Nunchuk method, since the joystick makes it easiest to power slide. The classic controller provides a joystick, but the controller is kinda small, and my hands cramped up when I tried it.

So in conclusion, I would say that Mario Kart Wii is not *quite* as awesome as N64, but it's close (maybe my opinion on the Wii will become more favorable if I ever get as good at it as I was on N64). I never even played Kart on the GameCube because I heard from enough reputible sources that it was a waste of time.

If you had used the exact same name for the library and the VIs you would have no relinking issues.

I used to use the same name, but that's what led to all my headaches in the first place. However, based on your comments it looks like the root of my problem is not separating "dev code" and "production code."

I'll apologize now for the length of my posts. I need to make sure I fully understand how all this fits together.

Here's the workflow I've been using:

Open a project that contains my top level application. (In my case it is a .lvlib I will use with Test Stand rather than an executable.) The Toaster, I2C Interface, and I2C Slave class hierarchies I am developing in parallel are listed under Dependencies. All the code is located in my dev folders. Dev folders and classes have version numbers in the names.
When I find something that needs to be changed in my class hierarchy, I check out the code, make a change, and check it back in. In most cases I have all the calling vis loaded so unexpected broken links isn't an issue.

I do this partly because I (again) don't know a better way and partly because it seems like it will be easier to move the source code to other computers. For this application I'm developing on one computer and running the code on a second computer. When I need to test the code I just open up Beyond Compare and copy it over to the test station.

Here's the workflow I think you're describing. I'm thinking through this as I type it up so tell me where I go wrong:

Develop each of my classes independently, perhaps by creating a single project for each hierarchy. Dev folders and classes do NOT have version numbers as part of the name.
Build my hierarchies to some location other than my dev folders, such as user.lib. If I use a tool that appends a suffix to the class member names, the vis I'm using in my top level application won't interfere with the class members in my dev folders.
When I need to make a change to my classes, I do so in the dev folder. I close my top level project and rebuild the class hierarchy to user.lib. Any application that uses those classes automatically uses the most recent version.

If I need to make a change to a class that breaks backwards compatibility, but I also need to use the previous version in projects...

Use the same dev folder for v2.0 that I did for v1.x. This allows all the links to remain intact during dev.
In my Source Dist build specs, use a different suffix for v2.0 vis than I did for v1.x vis. This allows both versions to be on the palette and used in applications at the same time.
(Optional) Send the Source Dist to a separate folder in user.lib. The versions will have different names so it's not required, but nice to keep the code separated.
I can only have one version of the class in my dev folder at a time, so if I need to modify v1.x I check in v2.0 and check out v1.x.

Assuming I have all that correct, I have a couple questions. (Big surprise.)

Is it best to wrap a single class hierarchy in a project and distribute it as a whole rather than have each class in a project and distribute them individually? My gut says yes, but I need to ask anyway.
When developing my classes, should any vis that are not part of my class hierarchy be taken from user.lib? I'm specifically thinking about my Toaster child classes, which include (as opposed to inherits) the I2C Interface base class. I assume I should be using those versions from the palette as they will remain updated whenever I build the class source code.
If I want to update the Toaster child classes to use I2C Interface v2.0, I need manually update all the I2C Interface v1.x vis/controls/typedefs the Toaster child class uses, since the v2.0 vis have different filenames, correct?
On the other hand, the Toast Master class inherits from (as opposed to includes) the Toaster base class, meaning I should inherit from and use those Toaster vis in my dev folder rather than user.lib while developing the Toast Master class? Otherwise I'm developing a child class using a previous build of the Toaster class instead of the Toaster class currently being developed.
If another developer (hypothetical, as I'm currently the only developer here) needed to do some work on my top level application, what's the best way to make sure he also gets the correct versions of the classes in vi.lib?
What's the best way to change my class names and vi locations (to remove the version number from the directory name) without completely trashing the work I've done so far? (AQ did address changing the name below...)

I use this to read user-editable configuration files for my project. By using XML with a schema, I can control the format of the file and verify that it adheres to this format when reading it. This allows me to abort application startup with a meaningful error message if someone makes an invalid edit to the configuration file.

This is also a good primer on how to read XML files using .NET calls. I hope you find this useful.

I also suggest you read some of the tutorials on the net about XML and XSD (schema) to understand how to create and edit your own files. In addition, I recommend XMLSpy by Altova for working with XML and XSD files.

The _Web Document Tool.vi is password protected in 8.5. Are there other ways to access the private vi server call?

You could use scripting workbench.

I'm actually in a user group meeting at the moment and saw a demo that appears to use flex.
Let me see what I can glean from my NI rep...

Cool , any help would be greatly appreciated.........

I think I should add that I believe this happens after a crash. I keep getting this error I described elsewhere that implicates Visual C++ when I try to write to a TDMS file. LV crashes after that. Could that leave a process running?]]> Thu, 04 Sep 2008 07:40:30 -0500 george seifert george seifert george seifert <![CDATA[It's Not A...]]>

This must be a US thing because when I was in Canada my kids would call "Punch Buggy, can't call it back". Then of course punch your neighbor in the shoulder. Same idea different call out.

Here's the "official" rules.

Or else "Punch buggy! No punch back!". There must be many variations on the theme.

Were a lot of high level people before us, but they didn’t gave us such a theory they left us in the dark. If I knew my theory when I was 15 years old my life today would be different.

The IQ test is related to mind not to intelligence.

You can ask for presidents, politicians with the 'intelligence fully awake' in USA and maybe the rest of the world will follow(difficult to do it in these post communist countries).

I read all informations on atmel site but I am confused.atmel said we can run WIN CE on that evaluation board by downloading BSP through SAMBA program.on the other side I wrote asimple application program on labview and build a exe file as they said for PDA win CE .on that condition I want to know how can I run this exe file on the evaluation board?.how can I access to different ports , timers, interrupts,... of at91sam9260 through labview.I think labview has good capability for writing high level program. I want to make SNMP agent by this evaluation board and I dont like write aprogram by low level language such as asmbly or even C . I think labview is the best choice because I dont have enough time to study more detail. I would be appriciate you if you could help me am i right or not?,is it possible or not ?,is there any example similar to my projects?

thanks and best regards

QUOTE (Daklu @ Sep 3 2008, 09:45 PM) <{POST_SNAPBACK}>

My cross-linking issues occur in the dev environment. Those solutions seem to be geared towards building executables. Am I missing something?

Yes, you miss something.
You should consider your own used classes as products. So you have a development source which is source code controlled.
For usage in other projects you make source distributions. However you need to rename those to prevent cross linking between development code and production code. This can be done in various ways, if you use VIPM you should change the custom postfix to make use of hierarchies of classes (I have a serious doubt if VIPM can deal with hierarchies of classes). The only thing you have to do in your production project is build the class hierarchy. Now if you need a new version of your class you can build your class, install it and the next time you open up your production project the new version will be loaded. (Make sure the production class isn't loaded during this action).

Here's your definition of relinking:

QUOTE

This process is much more cumbersome if I'm upgrading a lvlib instead of a class. Since the library vis don't have a dynamic input like class vis, I have to go through and replace every single control/typedef and library vi with the correlating item from the new library version. (I've uttered many curses for Labview not having a more customizable dev environment. Would it be that hard to enable more hotkey options? Replace With...?)

If you had used the exact same name for the library and the VIs you would have no relinking issues.
