String ASCII to decimal string and its sum

Hi all

I am a beginner in Labview and this is my first post on the forum.

I get a package series "1200F" on a MCU COM port. These are all ASCII characters.

I want to convert all of these ASCII characters into decimal numbers and add their decimal values to get the sum. So I took the ASCII string in a table using "Array of strings of bytes" and then typecast this constant using type U8. I put this in a loop and collects the decimal value using the Array function build. So I "Add elements of an array" function to add these decimal values to get the sum.

The problem is that for the input string, I am able to get the sum of "1200" only. At the time wherever I type the last character ASCII F, the sum does not. I see that when the sum exceeds 255 it resets again from 0. I have attached the VI for reference.

Any help would be appreciated.

Convert 32 to avoid the limitation 255 of U8.

  • search string and convert whole real or 8-bit 32 bit

    I was hoping to get some advice on how I could search for the following string and convert it to a real number or an integer.  The following data is output as a device ascii characters and I would look for both in each line (starting with 7699,72 seconds in this case) and convert each one to a real number.  Furthermore, I would like to get the integer values in each row (0, but could be 1,2,10,12, etc.) and convert them to an 8-bit integer.  I think that using the template Match followed by analysis of chain would screw that I need, but am not sure how to match in each case. Thank you!!

  • Extract a string and the following string

    I need to extract a word JNF and its following, if the JNF Word is found in a string.  Could someone help me with this please?

    For example.  "Proudct has this 10 oz bottle JNF 15 content."

    Here, I want to just extract JNF 15

    Hello

    In my previous answer, I assumed that JNF should be a whole word, not only the last 3 characters of another word.  In other words, taking into account this string

    ABCJNF JNF CAT DOG

    you would like to "JNF DOG".

    If you want "JNF CAT", then do this way:

    REGEXP_SUBSTR (str

  • Write a string and an integer and a table all in the same file?

    Hello

    I am currently it several different types of values with LabView.

    I have a shot, a few numbers and several paintings.

    Thus, for example, I have a timestamp of the chain, several values of "integer" amplitude of the signal for example, RMS value, frequency and I have several paintings - table of signal, the FFT (PIC and location) values.

    Basically, I'm trying to find a way to write all the values in a single file. I can write all the individual types to separate files (so I can write the RMS, amplitude and frequency to a single file, some of the tables in the other)
    but is it possible to write a string and an integer and a table all in the same file?

    Pointers would be much appreciated,

    Thank you

    Your file will be all text... any format in a table of text, to build as a single table, "table chain worksheet", to write to the file.

    I would like to give you an excerpt, but I've not updated this machine yet.  It's a pretty boring delimiter, if you know what's good for you, you start to use commas, tabs or simple spaces (my order of preference).  It is far too easy start add or remove spaces and then you need to use more complex methods to obtain data from worksheet.

    Is it always NULL?

    SELECT SUBSTR (p_csa, 1, 4) INTO v_comp FROM DUAL;

    You don't need the double table much in PL/SQL. You can simply say

    v_comp := SUBSTR (p_csa, 1, 4);
    

    Almost all integrated single-row functions work in PL/SQL. (NVL2 is the only one I know who does not work in PL/SQL).

    SELECT SUBSTR (p_csa, 5.3) INTO v_csa_prefix FROM DUAL;
    SELECT SUBSTR (p_csa, 8, 4) INTO v_csa_type FROM DUAL;

    If you don't want space, then only concatenate all the spaces in the string before you write it and REPLACE allows you to delete all the spaces that have been copied from p_csa. For example:

    UTL_FILE.PUT_LINE ( fileidinvoice
                , REPLACE ( v_telco || v_comp
                                        || v_csa_prefix
                              || v_csa_type
                       , ' '
                       )
                );
    

    I guess you need the v_comp of separate variables, the v_csa_prefix and the v_csa_type for something.

    I hope that answers your question.

    check = false

    which_balloon.y = 350

    }

    When you set which_balloon to line 3 of your code, you set it to an empty string. This will type the variable as a string. The strings cannot have a property there.

    What you probably want to do is type your which_balloon to the same variable type as some one and two and three are.

  • Comparison between a static value type String and a type perhaps unrelated number

    Well I have another question of my book of text... so far I typed in exactly how they ask me to and even followed some screenshots of examples of theres. All me looks good, but of course, I'm the only one with an untrained eye.

    When I run this film I get a compiler error of: 1176 20 comparison between a static value type String and a type perhaps unrelated to line number

    Here is my code

    import flash.events.MouseEvent;

    Stop();
    var numberOfCookies:Number = 0;
    startBtn.addEventListener (MouseEvent.CLICK, getCookies);
    function getCookies(event:MouseEvent)
    {
    numberOfCookies = (Math.floor (Math.random () * (10)) + 1);
    var n: Number = 0;
    While (n < numberOfCookies)
    {
    var cookieInstance:cookieMC = new cookieMC;
    addChild (cookieInstance) .x = (Math.random () * 200) + 20, (cookieInstance) there (Math.random () * 150) = + 220;
    n ++ ;
    }
    }
    goBtn.addEventListener (MouseEvent.CLICK, checkNumberTyped);
    function checkNumberTyped(event:MouseEvent)
    {
    If (checkBox.text == numberOfCookies) //this is the line 20
    {
    gotoAndPlay (2);
    }
    on the other
    {
    gotoAndPlay (3);
    }
    }

    The error indicates well enough the problem... the compiler doesn't like to compare different types of things.  In your case, a type is a string, and the other type is a number.  If you need to force one of them to become another type, and you can go either way...

    If (checkBox.text is String (numberOfCookies))

    OR

    If ((checkBox.text) Number is numberOfCookies)

  • Adding items to the multicolumn listbox and its headers

    How can I addEMS in multicolumn listbox and its headers?

    I don't see changes in CS4 is how to change the number of columns and headers to display.

    Thank you.

    Hi kingkai101,

    To configure headers, the columnTitles of the list box Properties attribute value an array of strings. To add a line, use the add() method of the ListBox to add 'something' for the first column of the row value, then the following columns are set using the value of the text of the element table [] subitems.

    I have attached a sample script. Hope it is informative.

  • Is it possible to have a common accessible file location for the main application in the sandbox and its extension app plugin

    I'm trying to launch an app on the app store for mac. The bundle of the main application and everything inside it is on sandbox.

    The main application Bundle identifier is com.xxx.core.app . The identifier for the internal Plugin Finder Extension application Bundle is com.xxx.core.app.extensions .

    Now the problem is the extension inner finder is also available in sand and trying to read a file written by the main application.

    The main application writes the file location depending on mac OS X, for example temp/var/folder/jv11743453495593/T/com.xxx.core.app

    But the internal Plugins try to read/var/folder/jv11743453495593/T/com.xxx.core.app/extensions

    Because of the different bundle identifiers, they have different containers.

    Can someone let me know how to limit the same application and its plugins to the same folder location. Does perform a work around for this problem.

    Hello yuktikapahwa,

    See the Sandbox Apple Guide under the ApplicationDirectory group container

    You must create a group that your container can access. I'm not 100% certain that this will work with extensions of Finder, but it seems the most logical place to start.

  • I downloaded an application from my iphone and then deleted. Now when I open AppStore I purchased apps and its still there. How can I remove it from there though even I have no more app?

    The applications that you have downloaded will be available for re - download also a practice.

    Apps y cannot be removed, you can hide only.
