MyRIO simple code compilation FPGA

Hello,
I am new to FPGA and I want to compile some simple code. I know that myRIO comes with default FPGA configuration so I want to create new one and compile it. Lets say that I want blinking LED. So I create new VI on FPGA and here is simple code:
then I add it to build and start compilation
As compilation goes it says that it will use 30% of FPGA resources:
Why is that? Whole compilation on cloud server takes more than 20 minutes. I have seen some example videos on CRio FPGA and that simple code should use no more than 2% of resources and shuld compile in 2 to 3 minutes.
What I am doing wrong?
Thanks in advice

Hey Pawhan11,
There are two main reasons for the FPGA resource consumption. First is that the FPGA on the myRIO (Zynq Z-7010) is relativly small compared to some other NI targets you may have used. The second reason that even a simple FPGA application takes ~20% of the FPGA fabric is because some of the FPGA fabric is already being used for other purposes. For example some NI Real-Time targets implement UARTs, RS232 or even ethernet in the FPGA to ensure consistency between devices.
Since myRIO is based on the Xilinx Zynq chip it uses a different toolchain than previous FPGA devices which may cause the difference in compile/synth times.

Simple code compiled in 1.6 but not in 1.5

Can any one tell me if this is bug in 1.5 or 1.6 ?
This code seems to me perfectly legal, but in 1.5 compiler issues an error, in 1.6 it does not.
Is any opened bug related to it so i can learn some more.
class TKey<T> {}
class TKeyWrapped<T, W extends Wrapper<T>> extends TKey<T> {}
public class AlonProblem<T extends Number> {
    public void test() {
        // this assignment cause the error
        TKeyWrapped<T, ? extends Wrapper<T>> resolved = getKey();
    protected TKeyWrapped<T, ? extends Wrapper<T>> getKey() {
        return null;
}The error is:

FYI, I just compiled this with 1.5.0_7. I get the same error from IDEA 5.2.1) (so presumably also from javac directly), but Eclipse 3.2.1 compiles it just fine.

Ask for help( simple code but wired error )!

The post I sent just now has some mistakes. This post is correct. My simple code is as follows:

The compiling error is:

I'm really sorry for being stupid. I'm just trying to understand what is going wrong. As soon as I get this sorted I can apply the principle to all other code I'm trying to write. I copied this code directly from my textbook used the SDK. Netbeans dosen't seem to like the way the textbook writes the code!

Erreur logiciel lors d'une compilation FPGA

Bonjour,
Suite à un bug durant la compilation FPGA, j'ai installer la derniere version de LabView avec la derniere version du NI-RIO, et effectivement le bug est parti !
Mais comme le bonheur ne dure qu'un temps, j'ai maintenant une erreur qui se produit lors de la compilation...
En cliquant sur le bouton "Détails" de la fenetre de compilation, le message suivant apparait :
Cette erreur peut elle etre due à mon code ou alors la raison est tout autre ?
Cordialement
Nathan

Downloading compiled FPGA bit file to target

Hello.
I'm trying to use multiple FPGA VIs in a same project, same target.
But, currently the Labview force me to re-compile when I want to run different FPGA VI in same project.
Even after compiling two FPGAs, the Labview program attempts to re-compile when I trying to run differnt FPGA VI.
So I refered http://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgahelp/compiling_fpga_vis_howto/ to download compiled FPGA bit file to the target to transit to another FPGA VI.
However, still the Labview program trying to re-compile the FPGA VI when I click RUN on the VI after downloading compiled VI to the flash of the target.
How can I solve this problem?
P.S.:
I checked off the option of the build specification that the FPGA VI does not automatically run when it is loaded to target and the target switch is on.

Are you sharing VIs between the two top-level VIs?
If they have any conditional disable structures with different settings then the sub-VIs will be marked as changed when opening the top-level VI for your second target.
Do you need to run the code in interactive mode or can you simply compile a bitfile and use that instead. That was the compilation requirement disappears.
I agree though that LVs rush to mark VIs as changed is a problem for interactive FPGA mode.
Shane.
Say hello to my little friend.

What's wrong with this simple code?

What's wrong with this simple code? Complier points out that
1. a '{' is expected at line6;
2. Statement expected at the line which PI is declared;
3. Type expected at "System.out.println("Demostrating PI");"
However, I can't figure out them. Please help. Thanks.
Here is the code:
import java.util.*;
public class DebugTwo3
// This class demonstrates some math methods
public static void main(String args[])
          public static final double PI = 3.14159;
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Change your code to this:
import java.util.*;
public class DebugTwo3
     public static final double PI = 3.14159;
     public static void main(String args[])
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Convert simple code from as2 to as3

Hello, i am looking for some help here for something simple (i think)
var txt:String = link1;
btn.onRelease = function():Void {
if( sample_id )
getURL("http://www.website.com/registration?partner_id=" + sample_id + "sampleURLCode", "_blank");
else
getURL("http://www.website.com/registration?sampleURLCode", "_blank");
Is there a way to make this simple code into AS3?

Hi, Apparantly that's because the 'link1' and 'sample_id' variables are not within the scope of the code you posted above, Perhaps you have defined them outside on a different frame or class. You can either define them with the same code like:
var sample_id:Number=1234; //Use your own variable type and value here
var link1:String = "your string or link URL here";
var txt:String = link1;
btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(e:MouseEvent)
if( sample_id )
      navigateToURL(new URLRequest("http://www.website.com/registration?sample_id=" + sample_id + "sampleURLCode"),"_blank");
else
      navigateToURL(new URLRequest("http://www.website.com/registration?sampleURLCode"),"_blank");
Or you can put a direct reference to your existing variable like (If your variables are defined on root/frame 1) :
var link1:String = "your string or link URL here";
var txt:String = MovieClip(this.root).link1;
btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(e:MouseEvent)
if( MovieClip(this.root).sample_id )
      navigateToURL(new URLRequest("http://www.website.com/registration?sample_id=" + sample_id + "sampleURLCode"),"_blank");
else
      navigateToURL(new URLRequest("http://www.website.com/registration?sampleURLCode"),"_blank");
try that, or you can share your .fla !

NI-Farm internal error - unable to compile FPGA VI

"An error occurred attempting to connect to this compile server.
Details:
NI-Farm Internal Error: Client received unexpected or bad data from the server."
The intermediate files are not generated, the error appears immediately after I select build from build specification, or after I click the run arrow.
I'm using local compile server.
The hardware I use: CompactRIO Evaluation Board - SbRIO9636, Laptop DELL, Intel core2 Duo, T5800, 2GHz, 3GB RAM, Windows 7 Ultimate 64bit, SP1.
Intermediate files CAN be generated w/o any issues, if I select from the menu. If I launch FPGA Compile Worker, a balloon message appears specifying that "FPGA compile worker is running" but after a few seconds, another message pops up: Multiple log on attempts have been unsuccessful - please see attached images.
At first I thought that my firewall(Comodo 6.3) is the reason for this, so I disabled it but nothing changed. Then I tried to repair LabVIEW FPGA, and XILINX tools with the firewall disabled but din not resolve the problem. I tried with both LabVIEW 2012 SP1 and 2013.
If you have any suggestions, please let me know! Thank you!

Solved!
Go to Solution.

Compile worker is set to local compile server. I could not start MAX 5.4 because of an Cmx exception, and after I upgraded MAX to 5.5, a missing dll error occurred. So long story short, I installed LabVIEW2013. Now MAX is working and I could generate a technical report. Only NI-RIO Server and NI License Server services were set on manual (or stopped?). I started both of them but still cannot compile FPGA vi.

Anyone have Simple Code to Play an .Flv file on a Website?

Hi,
Can someone please tell me how to make a web page play a .flv file.
Simple, basic code would do.
I have an .flv file uploaded on my website.
How do I get the Flash Player to play the file when someone visits the page?
Again, all I'm looking for is simple code.
Thanks,
Joe

add an flvplayback component to your swf. give it an instance name (say flv). then use:
flv.contentPath="yourflv.flv"; // for as2
flv.source="yourflv.flv"; // for as3

How can I allow user to customize the functionality of program at runtime? (not using runtime code compilation)

Using .NET Framework 4.0 what features are available that would allow to accomplish something very modular and user customizable, like depicted in this XML. Where I define specific base operations like Get() and Put() methods that operate on strings.
And allow the user to add and remove those or mix and match them in a way that they basically design their own run time functionality that suits them. So they just create their own 'Operation' and fill it with the operations they want to perform on some
incoming data type, in this case it is a string - with substring and insert methods.
EDIT - Assuming end user is non programmer and Dynamic Code compilation is not an option. I have an idea maybe using dynamic keyword, but not sure if it makes what i suggest possible.
<Operation Name="GetValues">
<Get id=123" FromIndex="2" ToIndex="23"/>
<Get id="234" FromIndex="3" ToIndex="5"/>
   <Output Path="C:\" Filename="testOut.txt" Append="true">
     <Format>
          <Result id="123"/> , <Result id="234"/>
     </Format>
   </Output>
</Operation>
<Operation Name="InsertValue">
<Put AtIndex="5">stringtoinsert</Put>
<Put AtIndex="36">anotherstringtoinsert</Put>
</Operation>

Hi sjs1978,
I am not familiar with dynamic code, and I made a research about it.
>> I'm aware of dynamic code compilation, but that requires user to input pieces of code.
Did you try to store the pieces of code into a file and call the code when the dynamic code compilation requires user to input code?
In addition, I found links about using code provider to compile a source file, and the links below might be useful to you.

Same float code compiled differently on different machines

Hi,
Scenario: same project build on different machines. and then both the application executed on
same machine .. giving slightly different results..(like 23.07499 to 23.07500)
project involves many float operations. project build on vs2013. c++
there is difference oberved in the final value of float calculations.. like 23.07499 to 23.07500
seems , Same float code compiled differently on different machines, any input
Regards,
james

>Scenario: same project build on different machines. and then both the application executed on same machine ..

Do you get consistent results with the same executable each time you
run it?
Assuming you do, and the only difference is the EXEs, what's the
difference between them - there must be something. Have a look at "How
to compare binary images of the same project builds"
https://support.microsoft.com/en-us/kb/164151/ and see if that sheds
any light onto the issue.
