Passing a Boolean true that once a loop

Hello world

I'm pretty new to LabView and worked on a project that uses it. I met a problem in one part of my code. I have a graph of wave form that reads tensions since a data acquisition card and I find the rising edge of it. When the edge flushing occurs, it produces a Boolean true am I on a case structure to trigger another event. The problem is the waveform data collection is in a time loop, because I think it takes to continue to accumulate data, it sends continuously the Boolean true until it is no longer on the front. I just want to send a boolean true when it hits the rising and wait until it hits again, because it's a sine wave.

I apologize that I don't have code to post right now, but any ideas or diagrams would be very appreciated!

Do not reinvent the wheel.  Just use the Boolean crossing PtByPt VI.  The output of your rising edge comparison goes into this VI and you specify "fake-real" sense.  The output will be TRUE on the first sample of your forehead.

  • pass the Boolean parameter?

    I need to pass a Boolean (true/false) for a full load, so I can shrink down tons of codes.

    But it's not working.

    How should the code look like?

    function myLoad() {}

    load codes

    var pass: Boolean = new Boolean (true);

    myLoader.contentLoaderInfo.addEventListener (Event.COMPLETE, function(e:Event) {loadComplete (e, col)});

    }

    function loadComplete(e:Event,_pass:Boolean):void {}

    If (pass = true) {}

    trace ("doing something");

    } ElseIf (pass = false) {}

    trace ("do something else");

    }

    }

    I don't know about the passage of the arguments by the listeners, but as far as contingency go, '=' is not what you want to use... "is" is for comparison.  And if you test the Boolean values you do not need to write the comparison...

    {if (Pass)}

    } else {}

    }

    And as I said, I know not for the passage of the arguments through designations of listener function, so if you've had success before, then very well.  I was led to believe that it's more complicated a case to solve.  Without knowing how, while it might involve more lines of code, I would use the conditional test to assign the listener rather than deciding which code to use the function loadComplete.  So I would like to use one of the two headphones and one of two complete functions through the...

  • Using a value Boolean true to increment a counter

    Hello world

    I would like to make a simple counter that waits just until a value Boolean true is passed and account 1, then wait until it happened again and goes up to 2 and so on. Just a single increment each time a real rose. I'm sure it's pretty simple, but I had no luck so far.

    Who does not resemble a need for a secondary loop.  You can add code to this loop to analyze the data.  If you do the calculations to determine a true, you already do the job.  Instead of going out a real, just increment a value of a shift register it.  Saves the hassle of sending one real constant for another loop for updating a shift register.  Do not create excess code just to have more code.

    Is it possible to do a button of Boolean true/false to require two mouse clicks to pass. We want this feature to avoid accidentally clicking on a button that opens or closes a valve?

    @Ian: while I think the general idea is very interesting, I don't like that calendar is encapsulated in the Subvi. While it is not hogging the CPU (which is good), it might give wrong impressions to new developers (no waiting obvious funktion in the loop).

    @OP: if it was only a double click to check, you could do something like in the attachment.

    I currently have two Boolean inputs that I would use to select a structure of business cases. I would like to have the four cases, each depends on the two Boolean true/false question. If variable Boolean 1 = true, then case 1 must be used, if Boolean 2 = true, case 2 is to be used, etc.

    Try something like the joint.

  • Values in the array of Booleans to dictate the output to be Boolean False or Boolean True

    I have a pretty simple question that I have a problem to solve.

    I'm looking to enter a Boolean array for a sub - vi that will take this table and dictate a single boolean output Boolean false or Boolean True.

    For example, the table will be table boolean 1 d, with a depth of 2 index values.

    -If the two index values are wrong then the sub - vi will kick for a False value.

    -If the two index values are true then the sub - vi will kick on a True value.

    -If an index value is True then the sub - vi will kick a True value.

    Any ideas?

    Thank you.

  • Elapsed time delay does that once in the state machine

    Hello.  I have problems using the delay to show the seconds remaining on an expectation not in a simple state machine.  I have a front panel countdown indicating the time remaining for the step.  I thought that the delay of elapsed time was the way to do.  The problem is the vi work correctly the first time.  But then after that the calendar does not seem to reset at the time I had put.  If I remove the delay and just stick a waiting time in the State, the vi is exhausted because I expect.  This is just to give the user an idea of the time remaining.  What I missing when using the passage of time, or it's just the wrong tool for the job?

    A small question, is that I would like to move the tasks, in this case the LED outside of the loop, so I don't have to repeat the code.  But when I tried moving them outside with only allow constants within the State, they do not work as I expected.  If you have tasks such as operating a set of Boolean values that you are used in several States, what is the the cleaner way to do it without repeating the code?

    Thanks for the help.

    See how it works for you.

  • It's true that I shouldn't update OS if I'm mid-FCP7 project?

    Hello!

    I'm working on a 2011 MacBook Pro 2.53 GHz Intel Core i5 with 4 GB 1067 MHz DDR3.

    I still have OS 10.7.5 and was told to update my OS in the middle of a very Long term documentary project which I hope at the end of this year. (I do not edit/rendering a lot on the laptop, just organize images to hand at the wide to a Publisher.) The laptop also has personal files, and even though I know I shouldn't do this, I'm stuck not being able to buy a new iMac because it would have the updated operating system, and as I understand it, I wouldn't be able to use FCP7).

    And Yes, I always use the FCP 7 and have already reduced sequences and have all the Organization of the project in FCP7.

    I know I'm running in trouble with the inability to upgrade, and as fast as I can go to the end, I want to be sure it's true that I can't upgrade my OS if I'm mid - FCP project. Anyone out there can confirm this?

    I need the hand out of a new editor who would like to update or change the editing systems, and I guess they will know more about all this... I just feel a little late and worried about the security and enforcement issues with always 10.7.5 and FCP 7.

    The operating system upgrade to another version can sometimes cause important disturbances, other times it works well and fine. Take a full bootable backup of your system to an external drive so you can cancel it if an upgrade problems. Time Machine backups are also useful, but they take longer to restore & are less convenient.

    If FCP 7 and your operating system works OK now I would leave him alone, the old adage applies - "If it's not broken, don't fix it."

    If you encounter other problems (such as inability to browse the sites you need because older browsers), then update, but don't forget that you have several days to investigate the fixation of what does not work.

    Security for your Mac can be better on a new OS, but simply by following best practices should enable 10.7 to stay quite safe for example browse to questionable sites with free software 'hacked', avoid to click on the links in the spam e-mail, do not install the software from random places you do not trust , stay out of other peoples wifi networks, use the Mac behind a router, use different passwords for everything...

    You should look at the apps rely you on and see if they work on the operating system you intend to upgrade to, look at this for reports from other users...

    http://roaringapps.com/

    Personally I don't never upgrades of the OS in the workplace that pays the bills or is critical in other ways.

    P.S. Please indicate what OS you plan to use and if you have already purchased on the App Store. Apple has removed the possibility of buying several older operating systems, so you will not be able to go for nothing, but the latest OS release. It is ins 't clear for me what model you have, use' Apple menu > about this Mac "to confirm that, to better help them."

    is it true that importation of the cam have been changed?

  • Is it true that I can not run more than 60 Hz on screen?

    Is it true that I can not run more than 60 Hz in 640 x 480 on my laptop with nvidia go 7600? or is there a driver for my lcd screen...?

    Why do you want to change the screen on the TFT screen refresh rate?
    LCD monitors do not suffer the same problems as their predecessors of the TRM and the refresh rate does not simply mean the same thing. LCD or TFT monitors will provide excellent quality and resolution at 60 Hz.
    Its response time, brightness of the Image and the Image contrast ratio the most important question for a TFT or LCD monitor.

    Operating systems set the different default refresh rate. Windows 95 and Windows 98 (se) together the highest refresh rate possible. Running Windows NT operating systems such as Windows 2000 and Windows XP descendants, however, by default the value of the for the 60 Hz refresh rate.
