• Writing Javascript vs C++ application logic functions

  Hi guys, new on Cascades here

  Example tl; Dr. waterfalls written app analysis functions of RSS in C++. The same functions can also be done in QML with Javascript itself.

  My question is, how do these two functions in C++ and Javascript compare in terms of performance? It will be wiser to write the logic of the application in C++ for the best performance?

  Thank you

  Jonathan

  Welcome on the support forums.

  Code c ++ will always have the possibility of better performance.
  personally, I had the experience that the logic of the qml/js implementation is possible, but more difficult to debug. It is sometimes easier to write well, so it's a business to another decision.
  I usually make more sense of the application in c + c++ / Qt and the UI in QML

• Logic function triggered by entering the framework returned error #1009

  I have five boxes to click on a screen (buttons with an area of key but no picture).  If a user clicks on a box for the first time, a graphic tick appears and a variable is set to True.  If the user clicks on the box again once the tick disappears and the variable is set to false.

  When the user clicks the next button the next slide will vary according to which the variables are set to True.

  That's all works fine, but if I go forward and then back to my frame, the ticks disappear.  I tried to create a new function to run as soon as I returned to the image, check if the variables are set to True or False and show appropriate ticks.  It works and there is no error when I run at the beginning of the film.  But when I click on the next button to leave the framework (framework 5) I get a lot of messages like this:

  TypeError: Error #1009: cannot access a property or method of a null object reference.

  Here is the corresponding code on picture 5:

  I worked there.

  I looked at http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/Event.html #ENTER_FRAME , who said that "this event has a"capture phase"nor a"bubble phase", which means that event listeners must be added directly to all targets potential, if the target is on the display list or not.

  So what I did is to change the event listener to say "box1Tick.addEventListener (Event.ENTER_FRAME, ticksInBoxes);".  Add this reference to one of the boxes used in the service was enough to get rid of the error message, even if the way in which the function ran did not this specific box visible.

• Button as a switch with logic gates.

  Hello, I am a student using LabVIEW 2012 as a FRC competitor, and I have a question/request to anyone who wants to.

  I can't find a non-buggy solution to get a button to work exactly like a switch. Either the solution train, or doesn't connect.

  I tried D type Flip Flop of all kinds, and! Q can not connect to D in LabVIEW (LabVIEW pulls the errors of "more than one data source", so a lot of logic functions that is available with other solutions, do not work on LabVIEW)

  NAND gate-types have been so tried, no dice.

  So if someone would like to help me, that's what I'm looking for:

  When the button is clicked, it sends a real constant function until the button is clicked again.

  -I can't use anything that messes with functions if the button is pressed.

  -J' I just need a simple on/off switch, nothing that goes 'around' from what currently exists and actually a buggy solution. It should be a kind of good way to do it.

  -An attachment of a VI would be nice, and what goes where.

  Thank you

  
  

• Transient analysis fails: Timestep too small

  I use Multisim 10.1 to assemble logic gates of transistors for an undergrad Electrical engineering class. Part of the specification is that doors should drive a 1 or 8 pF capacitor at the output in the 1nsec voltage. (I think that the circuit, which I've made available is the version 8pF).

  "Circuits work very well when I test for logical functionality with a frequency of input measured in seconds, but when I try to measure the time of release of a Ghz entry, the transient analysis invariably fails with a ' no time too small" error.

  I looked through the site or all kinds of possible fixes (adjustment of the values of the relative and absolute error, etc...), but no luck.

  for example, the project in question are: http://dl.dropbox.com/u/4286123/callforhelp.zip

  I would appreciate any advice, anyone can give me to help get the circuit able to run a transient analysis of higher frequency.

  Thank you!

  Student in EE, CSULB

  Hi Brian,.

  I took a glance at your circuit and it seemed that your cmos_andx8_timing_test_circuit.ms10 file generates errors of convergence. I did the following two changes in the settings of your transient simulation and circuit simulated very well:

  1. Scan options > SPICE Options > Use Defaults Multisim
  2. Crawl settings > settings > no time maximum (TMAX) = 1e-13 s

  As a general rule, you want to set the TMAX parameter to be substantially less than the smallest feature of your signal. In your case, the smaller is the rise in V1 (1ps) time. If possible, try to simulate with slower rise/fall times and slew rates. It is much easier for Multisim to converge semiconductor solutions if these settings were larger. I guess you do not have the luxury here, but if you were to just test the behavior of your circuit, it would be desirable.

  Hope that helped.

• management studio 2010 measurment PID control?

  Hello my friends.

  I am a .NET developer. I am new NI Measurment Studio 2010.

  as you know LabView has a PID and fuzzy Logic toolbox. now my question is this:

  measurment studio 2010 supports the PID?

  I mean how can we use the PID and fuzzy logic function and/or .NET 2008 libraries (if Possible)?

  If it is not possible with measurment studio, how and where can I find that libraries (PID for .NET)?

  Thanks for any help...

  NOR have a PID for .NET library. If you have a license for the CVI and CVI PID Toolkit, you can call in these libraries you .NET app. Or you can do the same thing with LV by creating a .NET interop assembly.

• VI for 18-48 48-18 value flip

  Hello, I am looking for a sollution to my problem. I have a PID, and the output is 0 to 100%. The low position of the servo is 48, the highest position is 18. I would like to have a vi that corresponds to 0-100% to 48-18 range of values.

  So 0-> 48 100-> 18.  I'm using the PID to EGU percentage, but it is does not seem to work with low value high and 48 18.

  Or I need a vi that "flips" between 18-48--> 48-18.

  I guess that's an easy task for experienced users.

  He is a math problem.  You want a function f such that f (0) = 48, f (100) = 18.

  We will choose the easier logic function, a linear relationship, who says that f (x) can be written f(x) = mx + b.  We will replace in extreme conditions and see if we can determine m and b.

  f (0) = m * 0 + b = 48, b = 48

  f (100) = 100 m + b = 18, 100 m + 48 = 18, 100 m =-30, m = - 0.3

  It looks like f (x) = - 0.3 x + 48 should work, that is, if we set 0, we get 48 and if we put in 100, we get 18.

  Let's try with 0, 50, and 100.

  f (0) = 48 (it was easy and 'correct')

  f (50) = - 15 + 48 = 33 (OK, we knew that before)

  f (100) = - 30 + 48 = 18 (also "correct").

  If f (50) has a meaning?  50 is to halfway between 0 and 100, and 33 is located at between 48 and 18, then maybe it does.

  Now, write a LabVIEW Subvi that supports x (which should be between 0 and 100 - you might want to think about adding code to deal with numbers outside this range, either by throwing an error, 'compel' values in this range, or whatever you think is appropriate) and display the position of the Servo.

• What is the use of FPGAS and how it differs from the IO Modules

  Hi all

  Maybe it's a silly question for most of you.  But I have very less knowledge about the basic concepts of electronic (FPGA, real-time) to cRIOs. I know that FPGA

  can be used to generate circuits within the chip that helps by some logical functions.

  I've just started working in the cRIO.  My question is that we have Modules e/s making it outputs all the application entry.  So, what is the purpose of e/s in the FPGA.

  Lets consider that we entered for an application of RTD.  In this case the module NI 9217 itself exits 24 bits of data from the RTD measurement which may be the process of the LabVIEW VI.  What will be this FPGA between the i/o Modules and the processor will help in?  Also I want to know what type of communication is used to send data between the FPGA and host modules.

  Thanks in advance

  Ajay HI:

  Sorry, you do not have an answer to your original question. However, you are right about the benefits of the FPGA. You said, if you build pre-processing in the FPGA, you can unload a lot of potentially CPU calculations out of the host processor. In addition, the program running on the FPGA is highly deterministic and can run the code very quickly. So if you build a kind of guard or evanescent dog part of your application, the FPGA is a good place to put it.

  To answer your other questions, communication between the modules and the FPGA is generally above the SPI and the data can be transferred between the FPGA and host via DMA FIFO operating on the PCI bus or single point save access using read/write in the FPGA host Interface controls. You can also use interruptions in signal of disputes between the FPGA host.

  I hope this helps, but let us know if you have any other questions.

• question about firewire ieee 1394 via chip.

  I have a hp pavilion a705w, missing a chip called "via vt6307" I see online is for ieee 1394, if I use not any device with a firewire port to this computer if they have problems or be less safe, or that make a difference, the chip has disappeared from the motherboard.

  Hi vilig,

  It is a design of single chip with full "plug and play" capabilities for integration in PC systems and electronic public, equipped with an interface HCI open and logical functions initialization and bus arbitration.

  Flexibility
  Has 2 ports supporting transmission rates up to 400 Mbps, allowing the use of multiple devices broadband simultaneously.

  If the chip is placed on the motherboard, it would be preferable that you contact the manufacturer for help on this issue.

  3. we need extract the lines which the corresponding brand values have values of very high/low i.e. assume a number of specific role is there which have markings about 20-30 but in a subject, he got in circulation 80-90, even as there are a number of role, one subject, he got 10-20 While in the other topic, he got 70-80.

  Thank you very much for your answer.  As always, it is really useful.

  Yes Sir, that's correct.  We are the lines where the student is absent from more than one topic.

  > You have Roll No. 3 with no AB at all, still rule 1. States 'AB marks in 1.

  Roll No. 3 is necessary output because it has 4 brands in the 4th topic while he got good grades in other subjects.  So that's the big difference with other brands of subject.

  > That means 'large fluctuation '?  There is no logical function for 'high fluctuation.  It must be clearly defined.

  Thank you so much for asking the question.  Fluctuation really means, if there is any subject whose marks are not in the range with another topic then this line is to have high/low difference.  For example in the other topic there are 30,35,40 brands exist but in 4th or any other he got say 3 or 5 or 0, then it is the line that have 'strong fluctuation' it please.

  I think it must be a column in the table that will contain a value from 0 to 9 for lines that have fluctuations.  Then it will be probably easier to select higher values of fluctuation; something like:

  Select * brand where fluctuations = 9; means here are the first few lines required, these lines have a difference higher for a topic to other brands of subject.

  Once again thank you Mr President.

  You have not yet responded to what 'large fluctuation' is.

  Computers do not work on subjectivity, they work on fixed logic.  Tell me that a student who scored 5 in a subject and 20 and 30 on two other subjects has strong fluctuation, but another person may say: "well, the marking is on 500, so 5, 20 and 30 are all a note very low and not really important fluctuation."  That is why we must be clear, what you mean by 'high fluctuation'.  As in my example, I specified it as the ratio between the minimum and maximum marks in less than 20%, but you have to tell us what the actual logic is desired; not a fluffy subjective idea.

  What are the changes from 0 to 9?

  Requirements must be clear in the calculation, not the ambiguous words.

  How about something based on average scores?

• Cannot move save as window in Acrobat ms

  Hello

  When I goto save a document in acrobat, there a small popup - when you say to save as and select the location to another folder, a windows Explorer window will open to allow you to choose where you want to save it - however that explore type popup fills the screen - the same screen the document adobe is behind.  I want to drag this window more so I don't have this problem.   The customer says that they want to be able to read the content of this document while typing the name of save it as if she doesn't have to keep swapping.

  
  This seems like a logical function to allow, but I can't understand how do.

  I applied the patches and repair adobe DC - the problem is still present.

• Local adjustments - mobile applications.

  I want to make local adjustments to photos from my iPad but it seems that global settings can be made in mobile Lightroom. Some healing/cloning in fix, but how can I make local adjustments exposure, highlight or contrast? Given the opportunity to use your finger as a brush, looks like a logical function but I don't see that it is available in any of my mobile apps Adobe CC. Signs would be appreciated.

  You cannot currently do adjustments local in LrMobile, although I would expect that adobe would work on this subject. However, there are other mobile applications of CC like Photoshop Fix or Photoshop Mix that can help you. I think that Fix may be the one to try first, but I've not used it much and there may be another application that does the job.

• Which cluster for the placement of DLR control VM?

  Intend to have 3 groups for a design of the NSX - calculation, cluster management (Infrastructure) and Edge? Cluster Edge willl have GSE and controllers.

  Who is the cluster recommended to place the DLR VM control, and what design considerations should be made?

  Thank you

  Ousmane

  The implementation of cluster is pretty much arbitrary as long as you have sufficient resources and groups necessary distributed port.  It would be wise to keep control of the DLR VM with the edges because it is a type of edge... Or it might be a good idea to move your DLR and the cluster in your cluster of right management controller, based on the logic function... that way the edge gateway data plane loads haveore has dedicated resources.

  With the placement of the bunch, his main concern should be the availability of resources to workloads in the cluster.  Secondarily, may give priority to the proximity of heavy workloads related? Other considerations are really just aesthetics.

  It is perhaps a good idea to examine the way which you cut the clusters.  What was your purpose behind this structure? Who is?

• Could not load any Windows OS on ESX 3.5

  Hello world

  I did some research on this one and I downloaded a ton of off-site Vmware site Web of LSI Logic SCSI driver, etc.  Right now, I'm to evaluate ESX 3.5 because I think currently for the virtual office road.  Now, I have installed a machine virtual Red Hat under ESX 3.5 and that works fine except that there is no network activity on the virtual machine itself (it's ok through).  The problem I have is when I try to load Windows (XP or Server 2003), I load the SCSI drivers and it detects the hard drive virtual and everything.  It creates the partition and format, and is preparing to copy files.  This is where the problem comes to the top.  I have read many other people have this same problem.  When he tries to copy the SCSI drivers, he says constantly, "can not copy the file.  I know that the diskette is inserted, I even used the image of diskette for BUSLOGIC which is integrated in the datastore of ESX 3.5.  I can NEVER get pass this point unless I have skip files, that is bad of course, because once it starts to load, I get a blue screen every time.  I saw the response of people saying just try this SCSI driver download and tried a ton.  I'm created flp files using WinImage and everything.  Virtual and real disks can all be corrupt because it does not load the driver in the first place (or so I wouldn't see the disc even perform a partition and format.  Anyone know why I can load but copy never works?  Any help is appreciated and thanks in advance.

  Another thing you could try is to make a NEW ISO with integrated drivers: http://www.nliteos.com/download.html
