• String hexadecimal "Hex Ascii" string!

  I'm having a mental block and wonder if anyone can help!

  I'm a device reading series and return a hexadecimal string. I need to view this hexadecimal string to the operator within a context area (PDA). The Message box will obviously contain normal text with the annex at the bottom HEX code.

  When I run the code for the pop up box shows the message readable for the user, but the returned HEX string appears in the appropriatte of ascii characters (because the pop-up displays a normal string).

  My question is, how to make a hexadecimal string appear in an indicator to display normal, 'same' string as it appears in its Hex display indicator:

  0x0A1C - hex display should appear as 0A1C in the channel display indicator.

  Thanks in advance

• String hexadecimal display indicator limit bytes per line

  Hey,.

  I was wondering if there is a way to limit the amount of bytes per line in a string indicator which is in Hex display mode.  I can read 50 bytes using VISA and I would look at a series of 50 bytes each on a new line.  I tried just to resize the indicator, but I have found that if the 50 bytes have a lot of great characters such as C and D, then it will spill over to the next line and become a mess to look at.

  I suggest to use a fixed width, like Courier New font. Thus, for 50 characters, it will always be the same length on the indicator.

• Transform a string that displays hex data in normal format, in a string that has the same data in hexadecimal format

  I have a string of arbitrary length - say, 1AB1C0 - normal format. I would like to have a function that takes this string in and generates the same accurate, but in hexadecimal characters. If the entry will read 1AB1C0 in the normal string format, and the output will read 1AB1C0 as a hexadecimal string.

  I'm doing this because I found that the terminal works better if I send the bytes string hexadecimal vs as an array of U8. Furthermore, I handle a lot of byte stream in my program and I find the chain tools less cumbersome to use against the array of bytes to analysis of analysis tools - however, they operate only on strings as they appear in normal mode. So I have reasons in different parts of my program to have the channel under conditions normal vs formats hexadecimal; but I can't understand anyway elegant remotely to cast from one to the other.

  Well, you must sweep the bytes of the string formatting hexagonal two at a time for a digital U8 and then cast to a string. There are several ways to do it, here are the two possibilities. (Sure to use the correct representation as Mkae labels).

• How to convert the binary value to a binary string in labview?

  Hi all

  I need to convert the binary value to a binary string. We have decimal or hexadecimal or octal number to decimal string, hexadecimal and octal string

  Hi pgm, use the function 'Format to a string. See the attached example. "%b" is the binary number in number in string format specifier.

• sum of series control is not not to

  I'll put up a VI to communicate with a device of air data. It communicates via RS - 232 with a string output that contains all data relevant, followed by a checksum, carriage return and line feed. An example of the output string is lower.

  094904104 111115, 0000.00 + 00.00, + 00.00, + 00106, 100051, 0100051, 33

  The documentation for the device has this to say on the calculation of the checksum. "The calculation of the checksum includes all characters and spaces except the return trolley/line flow of the characters and the checksum itself." The way I decided to calculate the checksum was to convert the output of a byte array and islolate string the first 69 bytes, i.e. all characters up to the amount of control (including the space that precedes) and then add the elements of the array.  It does not get me a checksum that matches reported. I don't know if I make a mistake in how I am to convert the string, or if the checksum calculation is more complicated. It's my first real attempt of serial communication so I hope I'm just a stupid mistake.  I'm guessing there are a few nuances about how one calculates a checksum that I must be missing.

  I have attached a simple vi takes the message string, which makes my calculation of checksum on it.

  His is a checksum XOR 1 byte as I suspected. The 33 is in HEXADECIMAL (decimal 51).

  The beauty of this method is a simple device as a microcontroller can:

  (1) receive the entire string, including the XOR checksum.

  (2) XOR all bytes set, including the checksum.

  (3) check that this calculation = 0

  If it is equal to zero the package is good for nothing function XOR with himself = 0.

  On a side note, LRC plans like this can have several incorrect bits and still generate the correct checksum, so CRSC is generally better, but in any case, LRC is better than nothing.

• Hexadecimal string to numeric value

  Hello

  I have a really (I think) a fundamental problem of trying to convert between a hexadecimal number to a 'digital constant' value so I can calculate certain things.

  The situation is: I'm able, a VISA series, a distance of an ultrasonic sensor reading. His current reading in an "indicator of string" ordinary put to a hexadecimal display. About 50 cm from distance with the ultrasonic at a wall sensor, I can measure "0032" as my display hex - what is optimal, 32 in hexadecimal is 50.

  However, my problem is, how do I now go to the conversion of this 0032 in hexadecimal in a usable digital/decimal numbers?

  Thanks heaps for you help.

• Conversion to hexadecimal string

  Hello world

  I'm using Labview 2012 and receive data on my serial port which I want to convert a hexadecimal string. I have attached a VI that only allows me to convert the first part of the string, but not the rest.

  Does anyone know how to do this?

  PS: I don't want to have just the incator displayed in hexadecimal format, I really need to do a conversion of the string to be able to work around it after.

  Thank you.

  See that red dot on the number of function Hex String in the image of the code, which is your data gets blown into a U64 array.  Yuk.  Drag a loop around the spell function channel number and it is actually a little faster.  Goes against everything you think you know all LV, but it's one of those exceptions.

• concatenate a string in hexadecimal with ASCII string

  Hello

  I'm new to LabView and I am building an application that talks to a camera. I'm stuck on something that seems simple enough: I need to concatenate a constant string of hexadecimal values (040D 0002...) with an ASCII hexadecimal string (00D0A10F, for example), which is emerging from a block 'number in string Hex. ' The output must be a string of hexadecimal values (040D 0002 00D0A10F) and go to the camera, but the block CONCATENATE transforms the ASCII string in hexadecimal display too, so that each character is converted to two hexagonal symbols...

  I found a very old post where someone claims that they have found a solution; Unfortunately, it is not displayed...

  Does anyone have an idea, how to do?

  Thank you very much!

  Michal

  Hello

  Give it a try - it converts an ASCII hexadecimal characters in ascii character string.

  So, if you view the output as hex, she must concatenate correctly with your other data.

• Hexadecimal string to HEXADECIMAL number

  Hello Experts,

  I just stuck in a simple problem. in fact I'm having an array of string HEX I want to convert it to HEX number format, I am looking for this conversion. It's that simple, but I can't do this job. Please see the image to join for more understanding.

  

  Soon harry and thnaks in advance

  Harry,

  You can do this (and many other conversions from string to a number) with analysis of the chain. %x indicates LabView input data are hexagonal. There are also a lot of string functions to a number (for example ' in hexadecimal string to the number") which could be faster if you do this 100 000 times in loop, but analysis chain will solve 99% of your problems.

• concatenate a hexadecimal string

  I'm trying to communicate through a circulation bath series, but it requires that all orders as a hexadecimal string.  I generate a portion of the string as a constant, but I need to convert a decimal point and add it at the end of the string.  I can convert the decimal to hexadecimal very well, but when I concatenate the strings is not hex ASCII format.  I tried a number of different tracks but am not having success.  Any help out there?

  Too bad.  I have it.  Just need to convert in I16 then catalogued for hex.

• How to find the bytes in hexadecimal string start

  Hi, I'm a freshman for Labview.

  I want to find the beginning bytes in Hex string. For example, 12 1A 00 34 1A 01 23... How can I get my data of 3 bytes of the hexadecimal string which starts at 1 'a '?

  Thank you for your help.

  You will need to provide more information. You have a string that has values of bytes like this? In other words, you have the control/indicator string value "hex display mode", and that you have provided, that's what you have? Or, you have the string in normal view?

  If it is in hexadecimal display mode, then use one of the functions of the chain to get a subset of the string. Have you looked in the channel palette?

  If it is in normal display mode, then you must convert all 2 characters to hex values.

  To learn more about LabVIEW, it is recommended that you go through the tutorials and look over the material in tutorials the NI Developer Zone Learning Center , which provides links to other materials and other. You can also take a course online for free.

• Convert the string of 32 bits to a hexadecimal number of LV 7

  Hello!!

  I have a 32 bit string I need to convert a hexadecimal number, what program I can do?

  Can someone help me?

  Thank you

  Each character in a string is a BYTE.  So you tell each of these I8s are 0 or 1?  If this is the case, then why not just use Boolean values (TRUE or FALSE)?  An array of Boolean would do this very simple since you can simply use the primitive Boolean array of numbers to do the conversion for you.

• quick help hexadecimal string

  I know it must be very easy (or I guess, it should be), but here's my question:

  Side block diagram, how I translated the string so that it enters the right hex format, so when my rope is 0907 in hexadecimal, my light. Basically, I can't format the string to a 0907 of weird symbol that it is now. I know it has to do with the way in which the string is stored as a "normal string" vs "hexadecimal string", but could someone show me how to easily switch between the two on the side of block diagram? (on the VI side its as simple as right-clicking, but I was in trouble he is).

  Thank you - and have a nice weekend together.

  Your channel is actually two characters \09 tab and \07.

  Your structure case string should be "\09\07" will be converted to "\t\07".

• Hexadecimal number to hex string

  Dear moderators of Labview and experts.

  I'm looking for a simple tool, but could not know.

  Could you help me?

  I want to convert a hexadecimal string, Hex number unchanged.

  I mean digital Hex display shows E8 and I convert it to a string and I have Open indicator string Hex window and get the same answer E8.

  Someone knows how to do?

  I thank very you much in advance!

  cast will do what you want.

  

  (Make sure that digital is U8 and the string is defined to display hex.)
