Increment and decrement with a Boolean value entered

Hello Experts Labview (and in fact life savers!)

I have a digital controller (button) in my VI, digital indicator, in addition to a Boolean of power input.

As an initial state, the digital display will contain a certain value (zero for example) and will only receive the variation in the button entry as long as the Boolean is true, and then add it to this initial value.

What is the change ? lets say that the button was on 8 before I touched the Boolean true, the value of the indicator is zero, and then I hit the Boolean true.

Now, when I move the button from 8 to 18 years (variation of + 10) , I want to receive the indicator + 10 and add it to the zero, now the result is 0 + 10 = 10

Now, the value is false, I move the button and nothing happens to the in the indicator 10.

Now, the Boolean value is true once again, let's say the button was about 4 at the time, I hit the Boolean true and it spend 4 to 1 (change-3) , the indicator value will now be 10 + (-3) = 7

I hope I explained the idea in a clear manner, I would be very grateful if someone could help me with this.

P.S. I have attached only the vi to illustrate the idea.

Thanks in advance

You care only remarks how the button changed.  Therefore, you must subtract the old value and the new value to get how to change the button.  Then add inside the structure of the case, this difference to your value that belongs in the registry to offset.

  • How to increment and decrement a counter with a single button

    Is there anyway you can increment and decrement a counter using only one button?

    I want this counter in place so that when I leave the stage and go back to it, the visibility of my button will remain the same because of being linked to the meter number.

    What would be the best way to implement that it doesn't work when I do it this way.

    function show_hide_MC(evt:MouseEvent):void {}

    MC.visible =! MC.visible;

    (Counter = 0) = (counter = 1);

    }

    btn.addEventListener (MouseEvent.CLICK, show_hide_MC);

    Thanks in advance!

    You can use a Boolean value (true/false) rather than a meter to keep track / affecting visibility.  You can use the counter simply to determine if you are starting the file or not.   When you click this button, you set the mc.visible property, and then assign the Boolean value of the visible property of the mc.

    var mcVisible:Boolean;    These two variables need to extend the length off the coast of the timeline
    var int count;

    if(Count == 0) {/ / you just started things so set up}
    mcVisible = mc.visible;
    Count += 1;
    } else {}
    MC.visible = mcVisible; you refer then set the visibility of the mc
    }

    function show_hide_MC(evt:MouseEvent):void {}
    MC.visible =! MC.visible; Toggle visibility
    mcVisible = mc.visible;    Remember how you left it
    }

    You can just use the number of establishments, incrementing every time that you click the button and using the module to determine if it has been clicked on an even number of times compared to an odd number of times, and then have a conditional that tests, which affects visibility... something like...

    var int count;           will start with a default value of 0

    We need to increase the length of the timeline

    If (count %2 == 0) {/ / this is the same value}
    MC. Visible = true;
    } else {/ / this is an odd value}
    MC. Visible = false;

    }

    function show_hide_MC(evt:MouseEvent):void {}
    MC.visible =! MC.visible; Toggle visibility
    Count += 1;

    }

  • Increment and decrement

    I want to do a simulation of increasing numbers and decrements up to a point. Let's say that I start with a constant of 10. I want to increment this 10 until it reaches 50. When he reached 50, I want to decrement, until the return to 10. And from there, it goes back to 50 and so on.

    I'm new to LabVIEW, and by looking at a few examples, I can do the part of the increment. However I can only stop the simulation when he reached 50, and it is not I want.

    Can someone help me with this?

    Hi guys

    I m new in the Labview programming and I m working with the NXT module in Labview 2010, and I have a few problems, because I m used to programming in C

    LabView is a kind of diferent than C

    The thing is wath I want to do a speed controller using the NXT brick

    Using the left arrow key increases the speed and by using the arrow button to the right the speed will decrease

    I m usin the actuator connected to the PORT has the NXT brick,

    Thank you

    Diego

    There is a communication i2c vi on the NXTI/O: Advanced palette that allows you to read/write the i2c data. You can take a look at the sensor ultrasonic VI, or saw HiTechnic sensors for examples of the use of this vi. You also need to configure the sensor i2c use port. You can use the VI 'Port of sensor installation' also in the palette of the advances to set the port for Lowspeed9V / RawMode

  • Coordinate the functions of Boolean values by their name

    Hi all

    I have somewhat a challenge I appreciate some help with. I am trying to create a program that synchronizes the function of a group of Boolean values by their names. If the Boolean values are names bool 1_i, I want that they be synchronized such that when for example a bool 1(1)(a) is turned on, then all the other 1_i bool are replaced by the same State.  The value group Boolean bool 1_i will initially be in the same State, but I'm trying to get a program that allows them to work in parallel like this.  I was able to make a table of 16 by 128 to work like this, where every row has represented the bool j_i group where I = j = 128 and 16. Now, I want to have the same function as a stand-alone Boolean values that are not placed in a table the table function palette.  Indeed, I am trying to get an array of Boolean values without creating a Boolean matrix in the traditional sense of the term. It is because I want the position to each boolean standalone to change while maintaining is synchrony with other Boolean values bound to her by name.  Any help on this would be highly appreciated.

    Here are the screenshots of the code that I used the 16 y 128 table

  • arbitrary hotkey to toggle a Boolean value (or increment/decrement a digital)

    Is it possible to assign the space bar as a shortcut to toggle a Boolean value from one State to the other (i.e. after the tab using FP and affecting emphasis as boolean)? More generally, is it possible to assign any key as a shortcut to a Boolean value (or a digital for its actions to increment/decrement)?

    The Advanced > button Navigation... Panel does not provide this option that I see (LV 2009 SP1).

    Thank you

    X.

    You can't assign arbitrary key to this action. What you can do, instead, is to use a structure of the event to intercept a key event and react accordingly. See attached example (LV 8.2).

  • by using a structure of the event to restore a Boolean control with change in value for the menu ring

    I'm trying to get two Boolean buttons to reset when the value of a ring menu.  For this I use a structure of event defined to execute with a ring value change.  However I have another code that should be run while the structure of the event expected to change value.  I place my structure of the event inside the while loop buttons reset as expected but my other code is not run (except when the value of change). If I place it outside the loop the rest of functions code as expected, but the buttons do not reset.  Any help you offer is much appreciated.

  • Mr President, how can I enter two rows at the same time with different default values that only the first line to use see?

    Mr President.

    My worm jdev is 12.2.1

    How to enter two rows at the same time with different default values that only the first line to use see?

    Suppose I have a table with four fields as below

    "DEBIT" VARCHAR2(7) , 
      "DRNAME" VARCHAR2(50),
      "CREDIT" VARCHAR2(7) , 
      "CRNAME" VARCHAR2(50),
    

    Now I want that when I click on a button (create an insert) to create the first line with the default values below

    firstrow.png

    So if I click on the button and then validate the second row with different values is also inserted on commit.

    The value of the second row are like the picture below

    tworows.png

    But the second row should be invisible. It could be achieved by adding vc in the vo.

    The difficult part in my question is therefore, to add the second row with the new default values.

    Because I already added default values in the first row.

    Now how to add second time default values.

  • A global variable is adjustable, and a Boolean value in LV3.1.1?

    A global variable is adjustable, and a Boolean value in LV3.1.1? I can do in LV 8.0, but 3.1.1 I need because of instrument gives me the penalty.

    All suggestions from users for a long time?

    Well, I'm a long time user, but that will come back some time.

    A global variable is basically a VI without a block diagram, so you should be able to place a Boolean control on the global variable just as you would place a digital command. Boolean values are treated differently at the time, but it probably won't affect what you do. The prices you say you tried, you can't put a Boolean value controlling this? I honestly don't remember not that is the case, but if this is the case, you can still use the functional overall construction, which is what we did before global variables have been introduced.
