integer to hex string

Hello gentlemen,

I'm having this problem try to send a 18 bytes in HEXADECIMAL string according to my device using the TCP Write.vi request schema

As you can see in the attachments, if I use the string concatenation function and hardcode the 18 bytes as constant as HEX display, the message is valid and the device responds correctly.

The next step is to have F and 11 as user input bytes, so I replaced the two constants '14' and '15' with two digital inputs and using the hexadecimal string number I hooked up the output of the function F of Byte and byte 11.

The output of the number of hexadecimal string is correct as I enter the value 20 and function converts to 14 (hex) if I have an indicator of the value to the normal display.

If I change the indicator to display Hex then I get the ASCII representation of the value 20.

The problem is that if I connect the output of the number of hexadecimal string to the string to concatenate instead of the constant value 20 is represented as "3134" as ASCII.

How can I convert a value of 20, which is a hexagonal I32 14?

I've attached a few screenshots of the code working with constants and does not not with I32 conversation Hex.

As your values may go in a single byte, change your your two entries U8 or I8 data type.  After that, just use Type Cast to change these bytes to a string.

  • How to convert the Ascii string containing hex to hex string info?

    Dear all,

    I am busy doing a control/reading program for pumps of ISCO.

    Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

    Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

    So to summarize:

    I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

    Thank you and best regards,

    Simon

    Try the attached VI, I changed the lag that you used in the chain of research/split of 2 because you view the input as hex string, so when labview works on the rope he works on the ASCII representation of the string (which is a character), even if your display is in hexadecimal (two characters with an ascii character) so you only need to divide at an offset of 2 instead of 4. For example, direction = FFFF.

    It depends on type of exactly what you want in the end.  Do you want a channel which shows the 4 characters who are the hexadecimal number for the number you enter.  Or do you want a channel which has only 2 (1 for each byte) characters, but the indicator is formatted to display those hexadecimal display?

  • How to scan a 32-bit unsigned integer to a string?

    I'm trying to analyze a 32-bit unsigned integer to a string value.  I tried to change the format from %d to %u string with no luck.  Maintaining the function return 0x7FFFFFFF (2147483647) when salvation bit is set.

    Can we define the format string such as LabView will show a 32-bit unsigned integer value?

    Thanks for your help,

    Phil

    No, use of %d. If you read these numbers in the %x, they will overflow. In addition, you must connect a constant of diagram U32 'default value' "channel scan" entry, otherwise you get I32, which is inusfficient for your data.

  • Concatenate an integer to a string for?

    Hello

    I'm new to LabVIEW.

    For my internship, I GPIB hardware control and to take certain measures.

    I use the GPIB write VI which accepts a string for its data entry.

    The command I want to send is of the form: "apply 5, 1".

    I thought to concatenate a string ('Apply_"), an integer ('5'), a coma and space (" ", _") and the last integer ('1'), so that I can increment integers in a loop if necessary.

    However, the VI of string concatenate does not accept the whole entries.

    Also, I think I'm going hard on this topic (I thought adding integers as strings, but then I won't be able to increment them at each iteration).

    Can someone help me?

    Thank you very much

    Nicolas

    You can use the Format function in the chain.

  • ASCII to HEX Strings BIG string

    Hello guys,.

    I know that it is already a lot of posts on this issue, but I couldn't find exactly what I need and also could not manage to solve it myself...

    I need to convert a string with ASCII characters in a string that contains these characters in HEXADECIMAL representation.

    What I did:

    Apparently, it works very well, but only for a limited number of characters defined by the representation of the data of the constant 0 (U64). It allows me to convert that 8 ASCII characters, as you can see from the image below:

    So, it converted from 0 to 7, but not the other characters (8 and 9).

    Any ideas?

    Thanks in advance!

    What is the data type of the constant plugs into the cast.  My guess is that it is a U64.  So it will be cataloged only the first 8 bytes of your string to a number, then you do hex on these 8 numbers.

    Use the string to byte array.  Or you could also catalogued where an array of integers U8 is connected to the conversion function.

  • normal string to hex string

    Hi all

    This question has probably been asked before, but I can't seem to find a situation that quite matches the issue I am experiencing. I have a table that I flattened as a string of data, reverse order, take the first two elements, reverse the new order and feed the characters in a loop for. I want the string to hexadecimal, thus having FE0C (in hexadecimal) through the loop for, but when I select the execution I see that normal display characters cross instead. When I view my channel, I already have a right-click to display the hex that is correct. How to convert the normal string to a hexadecimal string?

    Thank you

    J

    You can use Type Cast to change into a U16 (since it is supposed to be 2 bytes) or the Unflatten of the chain.

  • Conversion number to a hex string

    Hello

    I want to send a command string hex to a device via the serial port. The chain includes a fixed part (address, function, register) and editable part (setpoint). The fixed part is a string constant hexa (0106 0022) the editable part is a number (1000) converted to string hex (03E8). Finally, the two are coding pour get the final string. The problem is that instead get: 0106 0022 03E8, I get: 0106 0022 3033 4538.

    After concatenates two strings, it seems that the second part is turned into ASCI.

    I can't find the solution!

    Thanks for your help.

    Sorry, I saved the vi in a different version.

  • Concatenate the hex strings

    In the attached example, VI is there a way to have the 1 b be represented as Hex instead of ASCii after the output string concatenation? Why function concatenate strings automatically converts the 1B in ASCII?

    Rather than convert the number to a string of ASCII characters, you should change the representation of the byte in a string. If you always want only a single byte, use the U8 instead of I32 data type. Convert an array of U8. Convert to string. Concatenate. Lynn

  • Concatenation of Hex and bites of ASCII to get a HEX string

    Hello

    I'm trying to concatenate a MODBUS Application Protocol header with a function code and data that I send over TCP/IP to a motor controller.  I am running problems when I try to read my code function and data length.  I use "string length" to read the order data that I am seized, that convert a hexadecimal number, and then that the concatenation with some strings constant hexadecimal display and my function code and data which is also in the hexadecimal display. When I concatenate the lines, the end message is incorrect because (I think) the length of string, I have read and converted to hex in ASCII text?

    Does this sound as if that was the problem, and if this is the case, can someone help me to fix? If this isn't the problem can someone help me understand what is?

    Thank you

    Ran,

    Converting to hex it will show as ascii, it is what it is, a human readable number represented in hexadecimal. What if all you want to do is add the gross value, then convert this to tank and add it. For example, if you have more bytes data then 16 then you will add two additional bytes to the end instead of one.

    What if all you try to do is add a vale bytes that represents the amount of data you send simply converted in a single tank and add, as shown above. Of course, this means that the length of string cannot be greater then 256.

    Even if you have less then 16 bytes of data to the hexadecimal value added at the end is only 1 tank so unless the receiver is supposed to read a hexadecimal value, it will be always wrong. For example, 1 in hexadecimal read like 49 gross.

    Hope this helps,

    RGS,

  • Conversion to Hex string to a hexadecimal string that can be converted into a floating number with comma

    Hi, could someone help me please. I've been racking my brains out for almost three hours trying to solve this problem by trying different things.

    I have a code that retrieves a string of a robot control. The string is in hexadecimal and represents the number 1.234567. The string itself is 3FF3C0C9539B8887

    If I make a cast on the channel that I have, it simply returns the value zero.

    If I delete the control string, change it to hex and manually type in 3FF3C0C9539B8887 (so Labview auto updates 3FF3 539B 8887 C0C9) I get the result I need.

    However I can't find a way to do this. My apologies, someone out there is probably shaking he leads to something that is relatively simple, but I'm kinda new to deal with hex.

    Code is attached below in LV8 (although I'm under LV2012)

    The for loop is not necessary if you limit to 64-bit.

  • Conversion Date to integer to the string

    So what I try to do is to convert the results of a query. What is happening is that my data when the month is displayed as an integer from 1 to 12. I want to convert these numbers to the string month as Jan, Feb, Mar, and so forth. I tried using the DateFormatter, but I'm guessing that this does not work because he does not like the format that comes to him in the data. It is easier to explain by looking at my code:

    Here is my function to manage the date:
    public void fnShowMonth(item:Object,column:DataGridColumn):String
    {
    Return dfShowMonth.format(item[column.dataField]);
    }


    Here's Date formatter:
    < mx:DateFormatter id = "dfShowMonth" formatString = "MMMM" / >

    Here are the data grid I use for output:
    < mx:DataGrid
    ID = "grid2".
    dataProvider = "{cfcOutput}".
    >
    < mx:columns >
    < mx:DataGridColumn dataField = "MONTHS TOTAL" / >
    < mx:DataGridColumn dataField = "Month1" labelFunction = "fnShowMonth" / >
    < mx:DataGridColumn dataField = "Year1" / >
    < / mx:columns >
    < / mx:DataGrid >


    I used this method to other areas, but not a particular date field format. All I really want to do is convert these output numbers in a month in text in my datagrid. Right now, it gives me just an empty column "month1. I can get the numbers when I remove the labelFunction. Any ideas what I need to do?

    It is rather in bad taste, but it works. You'll want to provide verification of limits

    public static var months: Array = ["Jan", "Feb", "Mar", "Apr", "Peut", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "December"];

    public void fnShowMonth(column:DataGridColumn):String
    {
    back month [column.dataField - 1];
    }
