Conversion HEXA vers ASCII

Bonjour,
Je n'ai trouvé aucun outil Labview ni aucun post traitant de ce problème:
Convertir du ASCII en hexa n'est pas un problème, mais je ne parviens pas à faire l'inverse.
J'ai par exemple une constante chaîne de valeur 3C
Je souhaite la traiter pour obtenir une variable chaîne de valeur < qui est son equivalent en ASCII
Mon VI ne se résume bien évidemment pas à cela mais le principe sur lequel je bloque est rigoureusement celui ci.
Les valeur que je suis susceptible de convertir sont comprises entre 30 et 3F.
Je peux traiter ceci cas par cas mais ça me paraît inutilement lourd.
Y a-t-il un outil qui m'aurait echappé ?
Une méthode particulière que je ne connais pas ?
Merci d'avance

logique que tu ai 030D, tu converti une tableau d'octet, dois je te rappeler qu'un octet prend toujours 2 digits en Hexa, Puisqu’un digit par quartet.
c'est a toi d'extraire les données que tu veux (1quartet) de chaque octet, et de les lier 2 à 2 pour en fair des octets et ainsi pouvoir les lire via la chaine.
je rajouterais que labview et un peu lourd pour ce genre de traitement si facilement faisable en C.
mais je te l'ai quand meme fais (une bonne demi-heure de perdue!)
t'aurais pu chercher quand meme
je crois que tu vas devoir me mettre 5 etoiles, car la je bosse pour toi.

Convert hexa to ascii

Hi,
i converted this trame "444C4D535F436F6D6D616E6420313520C101C10046000060030AFF040016000A" to ASCII but i can't
found the right conversion in which i must found a special caracter like Â,Â,¬,...
What is the best way to convert a hex to ascii?
Thx for your help.

ASCII encodes 128 well-defined characters in 7 bit integers, see here, the Angstrom symbol and many other symbols do not belong to this code...
Also, this is a forum about CVI, not about learning coding in C, so you should add some question specific to CVI
Searching for strtol may be rewarding...

Hex to ascii

Now if i convert hex to ASCII and then back to HEX will the data be same.
youll say yes.I know.this holds good if the data is char or string
my question is what if double,int,float are converted to hex format and then converted to ASCII format and then back to hex format.
will the data be same.HELP
kudos welcome
Solved!
Go to Solution.

Please explain what you mean, because there are many ways to go from numeric to string.
The terms HEX and ASCII have no meaning unless you explain exactly what you are trying to do.
If you take a numeric (DBL, I32, U8, CXT, etc), you can represent it as a string using typecast or flatten to string, and the information will be retained bit by bit. If you later unflatten or typecast it back, nothing is lost.
Here, the resulting string is typically to readable, unless the string is displayed in hex format.
If you talk about formatting, you might lose a lot of information irreversibly. You can only format integers to hex format. If you format a DBL to a decimal string representation, you need to ensure that you show enough decimal digits. Even if you do, there will be small differences due to the inability to fully represent certain fractions in the other numeric system (binary vs. decimal). A formatted string is typically readable directly.
Please provide more information!

Help with binary to decimal, binary to hex, and hex to ascii or ascii to hex program

I decided to do a program that will do binary to decimal, binary to hex, and hex to ascii for a project related to a java programming course, which only needs to perform features from chapters 1-6 and 8 of Tony Gaddis's book. The functions work fine as their own main programs out side of this combined effort, so can anyone help me determine why I get the following 41 errrors saying: class, interface, or enum expected as well as any other errors that may show up afterwards because I'm stumped. My flowcharts, which have to be revised after discovering that my previous function were logically incorrect after running them in their own main are attached below as the spec sheet.
My code is as follows and I hope you don't mind the commented lines of unused code because I'm not sure where I want things and what I want at the moment:

so can anyone help me determine why I get the following 41 errrors saying: class, interface, or enum expected as well as any other errors that may show up afterwards because I'm stumped.
Yes - YOU CAN!
My code is as follows and I hope you don't mind the commented lines of unused code because I'm not sure where I want things and what I want at the moment:
Excellent! Commenting out code is EXACTLY how you troubleshoot problems like yours.
Comment out sections of code until the problem goes away. Then start adding back ONE SECTION of code at a time until the problem occurs. When it does you have just FOUND the problem.
If you do that you wind up with code that looks like this:
import java.util.Scanner;
import java.io.*;
import java.lang.*;
public class BintoDectoHextoAscii {
      public static void main(String[] args)throws IOException      {
         Scanner input = new Scanner(System.in);
         System.out.println("Enter a binary number: ");
         String binary = input.nextLine(); // store input from user
              public static String BinaryToHexadecimal(String hex)     {     } // end function
Notice ANYTHING UNUSUAL?
You have a complete CLASS definition followed by a method definition.
Methods have to be INSIDE the class - you can NOT define methods on their own.
Write modular code.
Write EMPTY methods - just the method signature and maybe a RETURN NULL if you need to return something.
Then add calls to those empty methods.
When everything compiles and runs find you can start adding code to the methods ONE METHOD AT A TIME.
Test compile and run after you add the code for each method.

Binary/hex to ASCII character

I am trying to send 8bits to a microcontroller, who understands ASCII characters. I am having trouble finding out how to convert my 8bits, or hex values, to the corresponding ASCII character....
i.e. 01010101 binary = 55 hex = U char
See the attached file...
Attachments:
Bin2Hex.vi ‏64 KB

Graz, sorry i posted in the wrong forum at first, but thanks for replying.
I am able to check what the microcontroller recieves, by activating 8 LED's corresponding to the byte. When using the attached file: Basic Write 1, wverything works great. The LED's will represent the byte exactly, for example 01010101 when sending the string "U" and so on..
For my project i need to be able to specify 8 bits (or switches) individually, and send this to the microcontroller, in the manner of the attached file Bin2Hex...
I basically just need to combine these two in the correct manner... something im yet to achieve..

GUIA Conversion EBCDIC to ASCII

Dear Gurus!!
I'm needing a manual or guide of the conversión EBCDIC to ASCII in the V5R3M0 iSeries. i570.
Can you help me?
Best Regards.
Luis

Hi Morga,
it has nothing to do with the OS release. You can stay on EBCDIC because of that as you found out.
But:
All release newer than 4.6D are in ASCII and UNICODE ONLY!
=> If you want to upgrade to e.g. ECC 6.0, you MUST convert to ASCII first ...
hope this helps,

File content conversion : hexa decimal character value for tab

Experts,
I am working on a FCC for a tab delimited file. Can any one tell me what is the hexadecimal value of tab. I am using '0x09' but it is not recognizing this.
Can anyone help me out..
Thanks
Veeru

Hi Veeru,
> I am working on a FCC for a tab delimited file. Can any one tell me what is the hexadecimal value of tab. I am using '0x09' but it is not recognizing this.
Have a look at this bolg /people/shabarish.vijayakumar/blog/2005/08/17/nab-the-tab-file-adapter . You can try the 2nd method given in that. If that doesn't solve your issue, might be there is some other problem in the FCC configuration.

ascii type i.
ascii = hex.
write: / 'Hex:' x, 'Ascii: ' ascii.

ASCII to XML conversion

LS,
I've been asked to check whether OWB can be used as a conversion tool for ASCII into XML.
I've found some references of OWB being capable of reading XML sources, but haven't found concrete answers about XML output.
Is it possible to use OWB to access an ASCII flat file (as an external table for instance) and then map the read data to an XML output file?
Thanks, Patrick

Patrick,
There are no specific features for converting ASCII files into XML, but OWB could be used for this purpose since it does write to file targets. The mapping would read from the ascii file as a source (you could use external tables for this, for example), perform the logic inside the map (wrap data in XML tags, etc.) and then target the output file. You could even use DB tables as XML containers / staging areas.
Regards:
Igor

Time comparision of ASCII conversion VS Unicode conversion

In general how does the runtime of a Unicode conversion compare to that of the ASCII conversion? For example, you perform the Unicode conversion on the same hardware on which you completed the ASCII conversion. The ASCII conversion takes 20 hours. Does the Unicode conversion take a similiar time?
thanx
Mark

Hi Mark,
first an answer, that comes only now, because my user was somehow locked or whatever ...
How long does it take compared to the ASCII CPC ?
As you are a latin-1 customer I guess, you could make use of the InPlace version in both attempts.
The InPlace Unicode CPC Export will take 6-7h or the time of the Ascii Export if this was longer. The reload will take about 3h only.
The major problem is on some other edge:
The combined upgrade only works fine if you run all the scans and this will take several days ... even when they are "pretty useless" in your case. Therefore, I would recommend an ECC6 upgrade without unicode and then the unicode conversion directly afterwards - in a short special technique, that I used several times already.
If it is "just" from 4.6C ASCII to ECC 6.0 Unicode, the week will be fully sufficient including all backups - which can sometimes run in parallel. (at least with my ideas)
I did something like that from 4.6B ASCII to ecc5 Unicode on one weekend from friday evening until sunday afternoon. (for sure, depending on the systemsize)

String to Packed ASCII conversion

Hi,
Can anyone provide any examples or Algorithm to convert 'ASCII' to 'Packed ASCII'
Packed ASCII format is used in HART protocol
Thanks.

Hi,
Packed ASCII is noting but a data compression technique.
HART makes limited use of data compression in the form of Packed ASCII. Normally, there are 256 possible ASCII characters, so that a full byte is needed to represent a character. Packed ASCII is a subset of full ASCII and uses only 64 of the 256 possible characters. These 64 characters are the capitalized alphabet, numbers 0 through 9, and a few punctuation marks. Many HART parameters need only this limited ASCII set, which means that data can be compressed to 3/4 of normal. This improves transmission speed, especially if the textual parameter being communicated is a large one.
    Since only full bytes can be transmitted, the 3/4 compression is fully realized only when the number of uncompressed bytes is a multiple of 4. Any fractional part requires a whole byte. Thus, if U is the number of uncompressed bytes, and T the number of transmitted bytes; find T = (3*U)/4 and increase any fractional part to 1. As examples, U = 3, 7, 8, and 9 result in T = 3, 6, 6, and 7.
    The rule for converting from ASCII to Packed ASCII is just to remove bits 6 and 7 (two most significant). An example is the character "M". The full binary code to represent this is 0100,1101. The packed binary code is 00,1101. The rules for conversion from packed ASCII back to ASCII are (1) set bit 7 = 0 and (2) set bit 6 = complement of packed ASCII bit 5.
    Note that, with some exceptions, HART Slaves don't need to do the compression or know anything about the compression. They simply store and re-transmit the already compressed data. Again, this is an instance where the more difficult software is placed in the device (Master) that is more capable of dealing with it.

Hex code to ASCII

Hey all,
i'm programming a web application to take in an ASCII Art from a text field in a web page and store it in an sql database so that the application displays all
the arts in another web page.
however whenever someone types in: {
it gets converted to %7b...
thats not a big deal but when the other web page displays the collection of ascii arts it displays %7b instead of {.
so all i wanna do is to convert the %7b to { before displaying it..
kindly help..
i wanna make a procedure which takes in something like: Hello%7bJava%7b!
and converts it to: Hello{Java}!
Ps. it should work for all hex codes and not only for %7b
please not: i want to convert only hex code to ascii and not disturb any existing ascii..
i.e in Hello%7bJava%7b!
hello and java must be unaffected while %7b should be converted to {
in other words i wanna convert only hex to ascii and not affect ascii

however whenever someone types in: {
it gets converted to %7b...It gets converted to that by what? Your Java code? Java JDK classes? SQL?
