LabView Embedded edition + Blackfin

Hello! My aim is to use LabView to generate applications and get C code as output, which I can alter before downloading to a Blackfin. It appears that the Blackfin Test addon, which I have on LabView 8, can only control Visual DSP++ and is not for developing applications; for one, I cannot see any special Blackfin Instrument Panel, as is claimed on the ADI website, where they use LabView embedded edition. Also, instrument drivers are not available for Blackfins, as such.
I want to know whether the full Blackfin instrument set is available for the standard LabView as well, or is it exclusively for the Embedded edition.
Thanks.
Kumar

For now, the BlackFin module only works with the special LabVIEW 7.1 Embedded edition.

Embedded labview module and blackfin 533

I need some advice for Embedded labview program integrated with Blackfin 533 Processor. The purpose is to input a value from a GUI in labview and store in a port/location in the blackfin board. Then, upon knowing this location, i can extract the value and use it in my main program in visualDSP.
Anyone know how to integrate them together as well as identifying where the value is stored in the blackfin? Im using blackfin 533 with Ez-Kit lite.
thanks

Just to be clear: The version of VisualDSP++ you need is not just VisualDSP++4.0, but VisualDSP++ 4.0 for LabVIEW Embedded. It is a special version created especially for use with LabVIEW Embedded. Go to the Help>About window in VDSP and verify that this is the product name. The evaluation version should not matter as long as the evaluation period has not expired.

LabView Embedded for BF537 and FGPA EZ-Extender

Hello,
I would like to know is it possible programming FGPA EZ-EXTENDER by usign LabView Embedded module - now we have BF-537 EZ-KIT and it works perfect, but now we woluld like to order FGPA Extender (or Bluettoth), but I have to know can I create programs for this module in LabView
Best regards,
Pawel Blaszczyk

Hi
Unfortunatelly, this daughter card is not supported neither by LV Embedded for Blackfin nor by LV FPGA. So you have to use the standard method of working with it, as described in VisualDSP++ documentation.
If you want to have similar functionality directly from LabVIEW (embedded system with FPGA), consider CompacRIO or SingleboardRIO.

LabView Embedded and Colinux

I am going to try to get LabView embedded to run with ucLinux on a blackfin BF537 EZKit. In doing my initial reading, it seems like the ADI toolchain is tested in Colinux but not in cygwin so I was wondering if anyone out there has tried running Colinux with LabView embedded and if so, how did it go. I don't know if it will really make a difference, but i guess Colinux is more than just an emulator, it is actually a second kernel that runs in paralell with windows so I am not sure how this will affect the whole process. I am new to the whole world of embedded programming andI am just trying to assemble as much information as I can before I launch into this to keep myself from wasting time on setups that aren't going to work. Thanks for the info.

Hi James,
I'm not aware of anyone running CoLinux with LabVIEW Embedded, though that certainly doesn't preclude the possibility of it working. At the moment, we have an entire LabVIEW module prebuilt for working with the VDK operating system on the Blackfin EZ-Kits, but we don't have a pre-built uclinux target available. If you're using the Embedded Development Module (and not the Embedded Module for Blackfin Processors), then we can make this happen by porting LV Embedded to a new uclinux target. As part of this process, you'll need to script the build toolchain to communicate from Windows to the build tools located on your Colinux virtual machine. One way that might work for you is to automate SSHing into the linux VM, sending it the file to compile, invoke your build tools, then send the result files back to LabVIEW on the Windows side.

Calling C libraries in labview embedded for ARM

Hello,
I wish to use the library
functions written by Luminary micro for their cortex-m3
controllers. If i wish to use these libraries written in C language in
Labview, what i should do? There are large number of libraries
available in their websites, if used in labview embedded, would be very helpfull and make programming very easy. If any one has implemented these libraries
in labview please write to me.
Nabhiraj

You can use the Call Library Function node.
study here and here
Start your work. Post if you stuck up anywhere. People here will help you a lot.
All the Best.

On how many computer can i install labview student edition?

I intend to purchase labview student edition in a near future, and i was wondering on how many computer may i install it. All for personnal use. I currently have 2 desktop, and one laptop. But I will soon get a surface 2 pro and my laptop start to be old so I will also replace it soon, and I was wondering if I could get the student version work on all those.

If you are a student, you can get a renewable 6 month license for free here. no need to purchase anything.
As for the number of computers you can install it, you need to read the Software Agreement. Look for section G(1). The software can be installed on up to three computers but can be used only on a single computer at any given time. If you get a new computer, just deactivate on the computer to be retired and activate on the new computer.

BOE XI R1 & CE10 Embedded Edition on same server OK?

We're (still) on BOE XI R1 and a vendor claims that their app can't use that RAS but instead requires the Crystal Enterprise v10 Embedded Edition.
(...this next ? may be a separate question altogether...)
Can you install multiple RAS servers on the same server?
Thanks!

LabVIEW Embedded - Performance Testing - Different Platforms

Hi all,
I've done some performance testing of LabVIEW on various microcontroller development boards (LabVIEW Embedded for ARM) as well as on a cRIO 9122 Real-time Controller (LabVIEW Real-time) and a Dell Optiplex 790 (LabVIEW desktop). You may find the results interesting. The full report is attached and the final page of the report is reproduced below.

Analysis
For microcontrollers, single loop programming can retain almost 100% of the processing power. Such programming would require that all I/O is non-blocking as well as use of interrupts. Multiple loop programming is not recommended, except for simple applications running at loop rates less than 200 Hz, since the vast majority of the processing power is taken by LabVIEW/OS overhead.
For cRIO, there is much more processing power available, however approximately 70 to 80% of it is lost to LabVIEW/OS overhead. The end result is that what can be achieved is limiting.
For the Desktop, we get the best of both worlds; extraordinary processing power and high efficiency.
Speculation on why LabVIEW Embedded for ARM and LabVIEW Real-time performance is so poor puts the blame on excessive context switch. Each context switch typically takes 150 to 200 machine cycles and these appear to be inserted for each loop iteration. This means that tight loops (fast with not much computation) consume enormous amounts of processing power. If this is the case, an option to force a context switch every Nth loop iteration would be useful.

LabVIEW Desktop has many attractive features. This explain why LabVIEW Desktop is so successful and is the vast majority of National Instruments’ software sales (and consequently results in the vast majority of hardware sales). It is National Instruments’ flagship product and is the precursor to the other LabVIEW offerings. The execution platform is powerful, available in various form factors from various sources and is competitively priced.
LabVIEW Real-time on a cRIO/sb-RIO is a lot less attractive. To make this platform attractive the execution platform cost needs to be vastly decreased while increasing the raw processing power. It would also be beneficial to examine why the LabVIEW/OS overhead is so high. A single plug-in board no larger than 75 x 50 mm (3” x 2”) with a single unit price under $180 would certainly make the sb-RIO a viable execution platform. The peripheral connectors would not be part of the board and would be accessible via a connector. A developer mother board could house the various connectors, but these are not needed when incorporated into the final product. The recently released Xilinx Zynq would be a great chip to use ($15 in volume, 2 x ARM Cortex A9 at 800 MHz (4,000 MIPS), FPGA fabric and lots more).
LabVIEW Embedded for ARM is very OEM friendly with development boards that are open source with circuit diagrams available. To make this platform attractive, new more capable Tier 1 boards will need to be introduced, mainly to counter the large LabVIEW/OS overhead. As before, these target boards would come from microcontroller manufacturers, thereby making them inexpensive and open source. It would also be beneficial to examine why the LabVIEW/OS overhead is so high. What is required now is another Tier 1 boards (eg. DK-LM3S9D96 (ARM Cortex M3 80 MHz/96 MIPS)). Further Tier 1 boards should be targeted every two years (eg. BeagleBoard-xM (ARM Cortex A8 1000 MHz/2000 MIPS board)) to keep LabVIEW Embedded for ARM relevant.

I've got to say though, it would really be good if NI could further develop the ARM embedded toolkit.
In the industry I'm in, and probably many others, control algorithm development and testing oocurs in labview. If you have a good LV developer or team, you'll end up with fairly solid, stable and tested code. But what happens now, once the concept is validated, is that all this is thrown away and the C programmers create the embedded code that will go into the real product.
The development cycle starts from scratch.
It would be amazing if you could strip down that code and deploy it onto ARM and expect it to not be too inefficient. Development costs and time to market go way down.. BUT, but especially in the industry I presently work in, the final product's COST is extremely important. (These being consumer products, chaper micro cheaper product) .
These concerns weight HEAVILY. I didn't get a warm fuzzy about the ARM toolkit for my application. I'm sure it's got its niches, but just imagine what could happen if some more work went into it to make it truly appealing to wider market...

LabVIEW Embedded - Support for device: NXP (ex. Philips) LPC2146 Microcontroller (ARM7)

Hi,
I would like to write some code in 'LabVIEW embedded' 8.5 for the NXP LPC2146 microcontroller (ARM7).
http://www.standardics.nxp.com/products/lpc2000/lpc214x/
The 2146 device is used within one of our main 'volume' products and I would like to write some special test code for the product in LV Embedded. I have the full NI development suite at 8.5 level.
The question is, does LV embedded suport this microcontroller fully?
I have found this info but still not sure: http://zone.ni.com/devzone/cda/tut/p/id/6207
Many thanks in antisipation of a reply.

Hi Andrew,
Using the LabVIEW Microprocessor SDK, you can "port" LabVIEW to build applications for any 32-bit microprocessor. The LabVIEW Microprocessor SDK Porting Guide describes the steps involved in the porting process.
The amount of effort involved depends on these factors:
How similar your target is to one of the example targets that are included in the LabVIEW Microprocessor SDK. As you can see in the article you linked, the SDK contains an example target with a Philips ARM and an eCos BSP. If your target is similar to this one (especially if the OS is the same), the porting process might take less than a week.
Familiarity with LabVIEW and embedded domain expertise. The porting process involves writing "plug-in" VIs in LabVIEW and building C run-time libraries for your target. However, once the porting process is complete, your target can be programmed solely in LabVIEW by someone with no embedded expertise whatsoever.
Target selection. We recommend a target have the following characteristics: 32-bit processor, OS/microkernel (not "bare metal"), and 256 KB RAM. Also, if you plan to make use of the LabVIEW Advanced Analysis libraries, a floating point unit is recommended.

It might help if you mentioned where this project is. Monthly "face to face" meeting is a little vague on an international forum.
I might ask what is to be accomplished in a "face to face" (presumably physically face to face) that can't, in this day and age, be accomplished with GoToMeeting, WebEx or Skype video meetings? I'm currently working on projects in Asia, Europe and Latin America, without having to leave my central location in N.America, except when I have to be present for actual hardware installation/commissioning. And even that has been reduced by Remote Desk Top, DameWare or some equivalent.

Upgrading from CR 10 Embedded Edition to Crystal Reports (server) xi

We recently upgraded from CR10 Embedded edition to Crystal Reports Server Xi. In our application the users access the reports via a web page (where they enter the paratemeters) and the report is displayed using the Crystal Reports viewer. The CR server xi was recently installed and all the SDK references have been as mentioned in this document: https://boc.sdn.sap.com/node/724. But now when the reports are accessed via the web page we are encountering the error 'All of your system's 0 Concurrent Access Licenses are in use at this time or your system's license key has expired. Try again later or contact your administrator to obtain additional licenses.---- Error code:-2147217397 Error code name:enterpriseLogonFailed'
Can anyone share your thoughts or provide suggestions?
Thanks,
in advance!

Hello SG,
A common issue that arises when migrating from Crystal Enterprise 10 Embedded to Crystal Reports Server XI applications that use the Report Application Server (RAS) SDK.
The RAS supports two modes of operation - "Unmanaged" and "Managed" reporting.
With CE10Embedded, you'd be using Unmanaged Reporting, where you'd copy the Crystal Report rpt file to the RAS server, and reference it by path when opening it in the ReportClientDocument class instance.
With Crystal Reports Server XI, you can use either Unmanaged Reporting, or Managed Reporting. Managed means you'd publish the rpt file to be "managed" by the CR Server Central Management Server (CMS). In code, you'd log onto the CR Server, retrieve the ReportAppFactory from the CMS, retrieve the report from the InfoStore, and pass it into the ReportAppFactory to create the ReportClientDocument.
I'm assuming you're still using "Unmanaged Reporting" with Crystal Reports Server.
If so, each report request will be authenticated in the CMS using the "Guest" account, and each request will use up a Concurrent Access License (CAL).
If you're getting the exception on the first report request, then that likely means you have the complimentary copy of CR Server XI, that comes with zero CALs and five Named User Licenses.
You won't be able to use unmanaged reporting with the complimentary version. You may want to modify your code to use managed reporting.
If you're getting the exception on the sixth or subsequent request, then that likely means you've purchased CR Server XI, and the base edition comes with 5 CALs.
If you contact sales, you can inform them of the number of users you have, and how frequently they request reports, and sales can recommend a license to match your requirements.
Sincerely,
Ted Ueda

Labview student edition

I recently bought labview student edition. How many computers will the license allow me to download to? I want to have it on my school and personal computer.

This is an excerpt from the general license file previously mentioned:
If the SOFTWARE is a student edition (including SOFTWARE acquired
pursuant to a student install option license), you must (i) be a Student or an Instructor; (ii) have acquired
a student edition license; (iii) only, if you are a Student, use the SOFTWARE for your personal
education purposes and not for any other purpose, including research, professional, commercial, or
industrial purposes; and (iv) only, if you are an Instructor, use the SOFTWARE for your preparation for
classroom or lab coursework and not for any other purpose, including use in a classroom or lab,
research, professional, commercial, or industrial purposes. The SOFTWARE may be installed on up to
three computers. However, only you may use or otherwise run the SOFTWARE, and the SOFTWARE
may not be run concurrently (i.e., it may only be launched on one computer at a time).
This agrees with what is mentioned in the README FIRST document for the LabVIEW Student Edition:
Installation is
restricted to your personally owned computer. http://www.ni.com/pdf/manuals/374075r.pdf
