• Delay the time of flat sequence Structure?

  How to delay the moment of execution for flat sequence Structure?

  Your question is a little vague.

  You want to delay in a certain amount of time? Until something happens?

  You can add a primitive frame with a wait.

  It might be useful to you could reach a simplified example so that we can better see what you're doing.

• Broken in the case of dynamic sequences accelerated

  Hey, I use CC Pro first and After effects CC and upon activation of a dynamic link to images are accelerating in Premiere Pro to After Effects: the film maintains has increased the speed, it's apparently random cut short. For example: say I had a second 20 long clip in first pro and accelerated it 200%, bringing in only 10 seconds. If I had to make this video in After Effects, the created model correctly would be long, 10 seconds and images inside would play at the correct speed... but a nonspecific part of it simply wouldn't be here. As if the clip had not included the missing part at all. I tried nesting the sped of the images before you bring it to After Effects, but that does not make a difference. I would be happy to provide you with a video demo of the problem if need be.

  I also have this problem. It's just a lack of functionality in the body. Do not use dynamic link with images that contain speed changes, it is unable to properly translate AE speed controls. Link to images unmodified, then apply the effect of speed in AE as suggested J. Simon.

• Replace the flat sequence Structure?

  I read a bit in the forum and a lot of people discouraged to use the structures of the sequence. Here's the situation: I have a tick count at the beginning for the iteration (and another at the end). I want to force them to count before (and after) anything else. The code I'm working on leash all data through structures flat sequences that contain only tick counts. Is there a different way that you can do without the structures of the sequence?

  The recommendation not to use structures of sequence applies to most of the cases where people use.  State machines are the preferred (and best) method.  However, this does not mean that there is never a good use for a sequence structure.  In your case, when you both want something, it is perfectly acceptable.  An example is shown in the first snippet below.

  There is an alternative however.  You can use a timed loop to time your code.  Someone posted here once an example.  I forgot who he was and who puts in.  It went something like the snippet of the second.

  I would like to know why there is a difference in speed between these two methods:

  

• Turn off the LEDs in the structure of the case

  Hello

  I was wondering if someone could help me solve a problem in a software test bench that I am developing. I have attached some of my code in which the problem is visible. I have a business structure that is triggered by a 'push button '. I want the TEST that is currently RUNNING LED remain lit until the end of the execution of the case structure (condition true) then shuts down once it is completed. But the LED does not turn off and remains lit. Is that what I can do in the condition False to activate the LED is off when the code is not running. Please note that to run the program, you will need to "run continuously. I want until the led turns off after getting the 'result' so that the software operator can know that he is free to perform the next test. But now when the 'Start Test 2 "is executed after 'Start Test', the LED stays on.

  It might be a simple solution that I can be not familiar with, but forgive me, I am a new user of Labview and I could not find a solution to this online.

  Thank you.

• The speed of the flat sequence?

  Hello

  What I want to do: read a map OR 6 analog voltages and provide a few analog/digital outputs from another card of NEITHER.

  Here's what I do: I use the DAQ assistant to acquire 6 different analogue voltages on a simulated map of NI 9205. I tried to run at the same time all 6 data acquisition assistant acquires (which did not), but I read that since there is only a single clock on the map, so I can not use multiple acquires at the same time because of timing issues (right?). Then, I put my DAQ assistants in their own images in a flat sequence then they would be operated sequentially. This works fine, but each frame/acquire takes 1 second to complete. Which means that my program lasts 6 seconds to do everything acquires it, before my other code outside the plate sequence. Outside platform sequence are my trips (some digital and analog a bit on a slider). Because my flat sequence lasts 6 seconds to compete, my outputs are updated only once every the 6 seconds, where as before the flat sequence has been inserted that they have been updated little almost instantly.

  Here are the questions: can I do the flat sequence run faster? Or is there a way to simultaneously acquire several analog voltage using the DAQ assistant. I feel that I shouldn't need to the apartment of sequences, but do not know a better way to go about it.

  I hope that makes sense and I'm pretty new to labview so feel free to add many details.

  Thank you!

  PS: If you try my Vi, notice how slowly the 3 top entries in the page update, if I remove the huge flat sequence, they run very quickly and smoothly, which is what I would like.

  Instead of trying to run 6 assistants for the acquisition of data in parallel (or sequential), use one assistant DAQ who reads all channels simultaneously.

• How to control the execution of a sequence of flat have the Cancel button

  Hello
  I have a question for you guys.
  Suppose I want to write a program to control a set of materials by sending commands via a serial port
  In fact, he calls a 'round '. Because a series of specific commands will send via a serial port at once specific time. What I call one a time Cycle.
  Between each send command steps there is a delay (waiting in range of Timing). The joint part of my VI.

  I was wondering how I can integrate a Cancel button which is able to act in any image of the flat sequence Structure?
  As you can see it is not everything in loops to have the best control of the program because I want to run commands in the series only once.
  Where to put the button 'Cancel' in frames?
  I want to show a confirmation message when the user clicked the Cancel button, and if the answer was 'YES' LabvIEW stops running flat sequence Structure and of the specific procedure to cancel (which is not included in above VI) takes place. Otherwise (by clicking 'NO') program continues to run...

  Note that home is just a simple version of what I intend to

  For example in some frames, it will be a while loop and so on...

  But there will be only on flat sequence at all

  Excuse me for my bad English

  Hi mostafi,.

  General answer: convert your flat sequence in a correct state machine States!

  Now, you can check your "Cancel" button after each State is treated...

• How to stop a flat sequence (or timed sequence) which is inside a loop for

  The problem is this, I have a loop that repeats 10 times and inside this loop, I have a flat sequence (or timed sequence) with four images, each of this chassis to evaluate a different condition of a vector that I introduce.

  What I woud like for example is:

  I'm a fifth County of the loop for and in the case that part 2 does not meet the condition, the sequence of dish (or timed sequence) stops and starts the loop again but this time for the number of number 6.

  I would appreciate your response.

  You can't stop a sequence structure.  This is how they are made.

  What you should consider to get rid fo structures sequence and to change a state machine architecture.  There are many examples in LabVIEW, as well as on the Forums.  The big advantage of the state machine is that at the end of each State, it examines the conditions and determines which State then run. And that is exactly the description of the problem you are experiencing.

• Front Panel does not (exactly 2 even while in flat sequence loop)? LabVIEW BUG?

  Hello world

  I have two while loop with exactly the same code and a user in each loop event structure,

  They both make the same thing which is too run until IMAQ image control (one line) click on a recording.

  I used a flat sequence to manage the order of execution.

  The problem is when I use only one single loop (put another in a diagram to disable) the façade answer perfectly and the program does what it should, but when I activate the two loops stuck in case of timeout...

  I do not understand what is happening that I can't do any activity of façade that would be registered, enclosed is a copy of the VI (you need NIVision run the vi).

  Any idea? Is this a bug or did I do something wrong?

  Thank you very much

  Best regards

  This isn't a bug, but the expected behavior. You cannot sequence structures event like this, they both need to be ready to react. Use a single event structure and a state machine architecture. You have about 4 copies of basically the same code of event management. Try to combine everything in one!

  What happens in your case?

  Answer: The two structures event will begin immediately queues of events, but the second event structure cannot respond to them because it is inaccessible due to data flow. In addition, the second structure of the event is set to "lock the front panel until the end of the event. Given that the event cannot end as explained above, the façade is locked up forever.

• Scripts (connect a Terminal to a flat sequence Structure)

  (script)

  Is it possible to connect a terminal to a flat Structure of the sequence?  (in my case, with a single frame)

  but the main question is... Why the flat sequence structure does not inherit from node?
  Why the developers chose this?
  What is the main idea of this choice?

  Flat sequence Structure introduced in LabVIEW 7.0, provides a semantic schema object that no other object has. It is a structure of multi-frame (like a case structure or a stacked sequence), but it is the only structure where data can be wired between frames through normal tunnels. It is the only structure which may have tunnels in places other than its external borders. It is the only structure that can have subdiagrams of different sizes in different positions. It also introduces scenarios of strange wiring that you won't find elsewhere:

  

  At the same time that the flat Structure of the sequence was introduced, there was enough of these bizarre scenarios with scripts (which was an internal feature NOR at the time), it was easier on the developer to make his own script class to try to find a way to support it under an existing class. We had no idea that script would become a public service someday, so the burden was relatively low and limited within the walls of NOR. Looking back, there have been enough problems with the FlatSequence class in the script than most of us agree that it would be better to have it in class Node (or more precisely, the class MultiFrameStructure) from the beginning.

• Switch timer within the structure of the case?

  Hello

  I am relatively new to LabVIEW, hoping someone can help me with something that I am trying to solve. I am working on a system for the acquisition of data for a formula SAE car and try to design a VI that will be time how long it takes for the car complete the trial of acceleration of 75 m. The timer will be actvated in now the pedal for 5 seconds and save time for the file when 75 m is complete.

  I've set up a business structure that works in the following order.

  1: Check the brake pressure (if threshold, go to 2)

  2: how long the brake was pressed for time. (If more than 5 seconds switch to 3. If the brake is provided within this period, date back to 1)

  3 whether the movement of the wheel (wheel strats move, go to 4, otherwise, keep control)

  4. begin to measure speed and distance. (once reached, proceed to 5)

  5. replace all over again, save the file (then return to 1)

  I'm pretty happy with everything but part 2. I tried a timer pending within a sequence of flat, check that the pressure is fine, but pedal pulses rather that now he can active it, and using a true/false with the same function case structure waiting does not like LabVIEW bed not true/false value, once within the structure of the case.

  I would be grateful if someone could point me in the right direction!

  Thank you

  Kevin

  get rid of the sequence, here your timer elapsed, also got rid of your case to check brake pressure, do not use ms of waiting for your timing of sequence...

  

• I just picked up a 12 inch I have pad PRO and bought a keyboard provided by Apple, however I find that the base remains unstable and keeps the hustle when you type, the seller it says it's a design flaw. Can someone tell me if this is the case?

  I just picked up a 12 inch I have pad PRO and bought a keyboard provided by Apple, however I find that the base remains unstable and keeps the hustle when you type, the seller it says it's a design flaw. Can someone tell me if this is the case?

  find it hard to imagine that Apple could sell these defective products.

  If the seller is an authorized Apple reseller, an independent company,

  You may need to ask you if you could see & try a different product sample

  because you might be looking at something that has a defect.

  {According to the related help page, Type position should be more

  stable to use. However if the keyboard is not flat, this sounds like default.}

  Sounds as if you're not at the official Apple Store (apple retailer)

  but, on the contrary, are somewhere else. Could you give more information?

  Some keyboard accessories are made by third party companies; so

  If the product has an Apple product model number, we note here.

  When considering the purchase of an accessory, it's a good idea to test

  and check in the store before you buy. An official Apple Store has

  a different return policy as an independent reseller of Apple.

  Don't know if I can be useful; These chat rooms are usually Apple

  users of products such as yourself, who have taken their unpaid time

  to see if they can help the other users of the product.

  Good luck...!

• Upgrading motherboard and CPU, can I keep the case?

  Hello

  He was considering upgrading my motherboard and processor in my Pavilion HPE h8-1020 with a motherboard ASUS Rampage Gene IV and a processor Intel Core i7-3960 x but I have two questions:

  (1) even if the mother is form Micro ATX factor, (supposed to be the same as the case form factor I've had with my h8-1020) will be the motherboard in the case so they still features with card readers, USB ports and LED?

  (2) Will Upgrading the major portions of my PC problems for the Original (Windows 7 64-bit) operating system that currently reside on my hard drive?

  I love the current aesthetics of my case and the system.  Hoping I can keep most of the features I currently have.  Thank you, your help will be greatly appreciated.

  Hello

  Look at models of bolt between two motherboards.  The i/o HP plate will not work with the ASUS card sort should use the i/o ASUS plate (hope it fits).  The ASUS Q-connector will help your with the front pin but write down it to the bottom of the function for each connector.

  Case diagrams should not be done.

• structure of flat sequence for benchmarking

  Hello

  Maybe this is very obvious, but I don't completely understand something with the sequence flat structures-FSS (I never use this structure by the way and I don't you not why they use it in this example).

  There's a doc OR online explaining some mistakes of rookie in LV:

  http://www.NI.com/newsletter/51735/en/

  The doc has described that the FSS is useful for benchmarking, the BD:

  

  My question: what if we put the number of cycles in a Subvi left and right and giving the exec. order with wires of the error? Or using a while loop that runs only once (with sons of error through)?

  These 3 different ways are the same?

  Yes, you can do all these things - I think that the only thing to keep in mind is that you do not want your benchmarking code to affect the speed of the code - otherwise, you'll get inaccurate results. If you use the while loop, you will need to do something to make sure your second number of cycles will run after your time loop - for example with FSS

  Flat sequence structure using is OK - it's overuse of it which is a common rookie mistake - trying to force things to run in a specific order (for example if from a text based on the sequential programming language) instead of understanding that this is done by data flow in LabVIEW.

  I think that the reason is simply because the number of cycles VI doesn't have an entry so you cannot apply data flow. It is common to have a Subvi, which encapsulates the number of cycles VI with error/output wire.

• Store/communicate IMAQ image (binary) between the structures of the case

  Hi all

  I am trying to build a VI for a controlled industrial vision system and it has 2 process: first an image of calibration comes a sequence of discrete of images. After that, the user can start and stop the continuous controlled process of machine vision. This process then uses the calibration image to remove some background objects etc..

  As the two processes cannot run at the same time, I programmed it as an event-driven state machine (following this tutorial: https://www.youtube.com/watch?v=RuIN31rSO2k) combined with continuous acquisition.

  My question is how to store and communicate the image of calibration between the structures of the case. It is basically a static image that is generated at the start of a race and then used once during the continuous control loop.

  Now, I tried storing in an IMAQ control with a local variable, but it does not work when I try to read the image. Preference image must be passed the bottom without any interference of the façade. I could probably make it work if I pass on the image in a table and then convert it back, but I want to avoid unnecessary conversions and understand how to manage the images correctly.

  Joined codeblock showing the part where I (attempt to) store the image and how the process of continuous measurement is connected (Yes, I know the live view is wired incorrectly in the scheme of the latter, it was a test to show a colleague).

  Thanks in advance for any help!

  Consider placing the image, the data record in a turn on your main WHILE loop.
