Convertir des caractere ASCII provenant d'un RS232 en Hexadecimal

Bonjour à tous
je recois via du RS232 des données en ASCII sur 27 octets
comment puis je convertir cette chaine ASCII en chaine hexa
exemple pour les caracteres ASCII suivant : (01// conversion hexa ==> 28 30 31 2F 2F
merci beaucoup, je galere vraiment (un .vi serait le bienvenu ! ;-)

Voila ton VI !
C'est du quasi ce que tu veux, sauf que je présente le code des caractères ASCII dans un tableau...
La fonction TypeCast te permet de passer d'un visualisation de donnée à une autre...

Lire des donées provenant d'un pic via une liaison RS232 et écrire dans un fichier xls

Bonjour à tous,
Le but de mon projet est de lire et d'enregistrer des données provenant d'un microcontroleur pic. En fait le pic enregistre des données et les stocke dans une mémoire flash. Ce que j'aimerais faire c'est récupérer les données stockées dans la mémoire, les afficher sur un graphe sous Labview et les enregistrer dans un fichier excel. La communication entre le pic et le pc se faisant par RS232.
Merci par avance pour vos suggestions.
Bien cordialement.
Philippe

Bonjour Philippe,
Ici tu es sur le forum en anglais. Essaie de poster en anglais
Sinon voici le forum francais où tu auras plus de chance que l'on te réponde.
Pour ce qui est de ton projet, je te conseille de regarder vers les fonctions VISA pour ce qui est de la communication RS232.
Il faut récuperer les données pour les mettres sous forme de tableau par exemple.
Pour l'affichage des valeurs et l'enregistrement en tableau se fait assez simplement. Il y a une fonction Write to a spreadsheet file (dans files I/O) qui permet d'écrire directement une tableau 1D ou 2D.

Instrument I/O Assistant:Convertir les commandes ASCII en numérique?

Bonjour à Tous,
Je suis à la recherche des exemples d'applications et des liens sur les assistants E/S d'instruments dans le but de développer un driver pour power supply Haut Voltage.
En effet ,dans le cadre de mon projet j'ai utilisé ces Assistants E/S directes pour communiquer (Commandes en ASCII ,Reponses en ASCII) avec des alimentations Haut Voltage de type MPS Spellman et le programme fonctionne très bien.
Pour la suite de mon travail je voudrai utilier des commandes Numériques (Décimal) sur la face avant du CODE VI standard obtenu après conversion et avoir des réponses en numérique pour l'exploitation (Ci joint le Code VI Réalisé)
EXP de commandes: stx 12 EN1 Y lf = ON ( Enable )
                                    stx 12 EN0 z lf = oFF (Disable)
                                    stx 12 V1=5 d lf : Pour appliquer 5Volt
,,,                               stx 12 V1=1000 X z lf : pour appliquer 1000 Volt
Je sais pas si des fonctions existent sous Labview ou il faut écrire un autre de programme de calcul? si quelqu'un a des remarques ou des suggestions à faire,,elles seront les bienvenues Merci à bientot.

Convert char to ascii code and vice versa

HI
Is there any function module to convert char to ascii code and vice versa.
Thanks in advance

Hi,
be careful if you have unicode running in your system. URL_ASCII_CODE_GET is platform-dependent so it will return the internal HERX representation of the character in your system - which is hopefully and in most cases ASCII.
Under unicode, we use double-byte characters here. I tried this function and the result CHAR_CODE is '00' regardless what character I specify for TRANS_CHAR. But the coding is so simple I corrected resultig in this sample code:
[P]
convert p_form to ASCII (internal) representation
DATA:
    l_ofs TYPE syfdpos,
    l_len TYPE sy-linsz,
    l_ascii TYPE i.
FIELD-SYMBOLS:
    <x> TYPE x.
l_len = STRLEN( p_ascii ).
DO l_len TIMES.
    l_ofs = sy-index - 1.
    ASSIGN p_ascii+l_ofs(1) TO <x> CASTING.
    l_ascii = <x>.
    WRITE: l_ascii.
ENDDO.
[/P]
Here, for each character of string p_ascii, the internal (ASCII) representation is determined and written to the output list.
Regards,
Clemens

Problem convertting certain extended ascii characters

I'm having problems with the extended ascii characters in the range 128-159. I'm working with SQL server environment using java. I originally had problems with characters in the range 128-159 when I did a 'select char_col from my_table' I always get junk when I try to retreive it from the ResultSet using the code 'String str = rs.getString(1)'. For example char_col would have the ascii character (in hex) '0x83' but when I retrieved it from the database, my str equaled '0x192'. I'm aware there is a gap in the range 128-159 in ISO-8859-1 charset. I've tracked the problem to be a charset issue converting the extended ascii characters in ISO-8859-1 into java's unicode charset.
I looked on the forum and it said to try to specify the charset when I retreived it from the resultset so I did 'String str = new String(rs.getBytes(), "ISO-8859-1")' and it was able to read the characters 128-159 correctly except for five characters (129, 141, 143, 144, 157). These characters always returned the character 63 or 0x3f. Does anyone who what's happening here? How come these characters didn't work? Is there a workaround this? I need to use only use java and its default charsets and I don't want to switch to the windows Cp1252 charset cuz I'm using the java code in a unix environment as well.
thanks.

Normally your JDBC driver should understand the charset used in the database, and it should use that charset to produce a correct value for the result of getString(). However it does sometimes happen that the database is created by programs in some other language that ignore the database's charset and do their own encoding, bypassing the database's facilities. It is often difficult to deal with that problem, because the custodians of those other programs don't have a problem, everything is consistent for them, and they will not allow you to "repair" the database.
I don't mean to say that really is your problem, it is a possibility though. You are using an SQL Server JDBC driver, aren't you? Does its connection URL allow you to specify the charset? If so, try specifying that SQL-Latin1 thing and see if it works.

Two Spaces being converted to from ascii 32,32 to ascii 160,32

Two Spaces being converted to from ascii 32,32 to ascii 160,32 when the page is
loaded by the browser.
This problem is exhibited when viewing an address page in personal data that contains
two spaces in the address field. i.e.. APT102- 102 Elm St.
We put debug traces in to display the ascii character values of the spaces before
and after the record is brought up. This debug showed that the two spaces change
from
Before: space,space or ASCII(32),ASCII(32)
After: ASCII(160) ASCII(32)
This is causing the application to display a record change warning. This occurs
on IE 5.5, 6.0, Netscape 6, but DOES NOT occur using the Opera 6 browser. For
what it's worth, the database is Non-unicode.

How to convert tdms to ascii files?

Hello,
I need to convert *.tdms files to an ascii file. I have 16 channels and scalling coefficient information in the tdms file, With the TDMS-Image Viewer i can see the 1-D array waveform perfectly, but I cant write it to an ascii file. When I use a signalexpress.vi or the spreetsheat.vi for writing an LVM/ascii file, information gets lost. (Red symbol at INPUT!!!!)
Please answer me, because I dont have lots of experience with labview and an ascii file is more easier to handle for me! I found only export to matlab and exel, but i just want it in an ascii file. Reading the tdms and opening it is no problem, but connecting the right blocks to the 1D array waveform without dataloss doesnt work.
thank you for reading
danny

Thank you for reply,
i have the new version 8.5. With signalexpress.vis i can do asciis but the red symbol (at input) is there so i dont want to get information lost.
The tdms file has header information for scalling factors and unscalled data for 16 channels.
so because tdms files are faster for writing i want to convert them to ascii with a Convertion Vi, but it seems that with an express vi he stops because it cant handle handle with the headerinformation.
now i use the signalexess vi to write tdms data, before i did it manully by setting channel and group information.
Please tell me if the red symbol AT input of a Signalexpress VI does matter? its a 1D array wavefrom that goes in to the input.
thank you for this discussion, i hope that i dont need to use the matlab import option for tdms!!
greetings danny

Importing COBOL copybook into OSB & converting it to ASCII

Hi,
I want to import a COBOL copybook(.cpy/.copy file) into OSB.
Based on that copybook, there is an EBCDIC file which I want to convert into an ASCII file.
I used Format Builder to import the copybook, but it does not show any indication whether the copybook got imported or not.
Please help... this is urgent..

There was a problem with the copybook... so it was not imported.
The corrected copybook got imported perfectly.

Convert String from ASCII to ANSI

Hi,
a command line instruction via LabVIEW function "System Exec.vi" retrieves me a string in ASCII format. Is there a function to convert string from ASCII to ANSII format? I use LabVIEW 8.5 German Installation.
Kind Regards

Hallo Christian,
AFAIK there is no such in function in LabView...
But you can:
- use "Search and replace string" to search for ASCII chars and replace them by their corresponding ANSI char, do this in a loop for all chars to be replaced (acceptable speed for small strings...)
- convert the string to an U8 array and use a lookup table to convert all bytes from ASCII to ANSI, convert back to string (may be faster for long strings...)

Comment convertir des fichiers Flash écrit en AS2 en html 5 avec Flash CC ?

Bonjour,
j'ai créé des présentations multimédias il y a quelques années en Flash en utilisant l'AS2 ces présentations sont constitués d'une multitude de fihiers swf qui se supperpose (loadmovie). Je dois aujourd'hui en faire une version html 5. J'utilise adobe CC et l'extension de Google Swiffy ne fonctionne pas sur cette version. Existe-t-il un moyen simple de convertir ces fichier écrits en AS2 en html5 ?
Merci d'avance de vos réponses.

I'm basically trying to do the same thing.
I have two swf files and I need these as flv files.
I looked for some freeware to convert swf files to flv. The only ones I've found so far leave a watermark on the flash video file. As I only have two files to convert (and this is probably a one-off occasion), I am loathe to spend a fortune to do this....
We have a graphic designer here at our company with Flash CS3. Is it possible to do it within Flash?... or is anyone happy to convert them for me if they have the tools and if I email them to you?
(Pour Isabelle en français): J'essaye fondamentalement de faire la même chose.
J'ai deux dossiers de swf et j'ai besoin de ces derniers comme dossiers de flv.
J'ai recherché du freeware pour convertir des dossiers de swf en flv. Les seuls j'ai trouvé jusqu'ici le congé un filigrane sur le dossier visuel instantané. Car j'ai seulement deux dossiers à convertir (et ceci est probablement une occasion unique), je suis déteste pour dépenser une fortune pour faire ceci….
Nous avons un concepteur ici à notre compagnie avec le flash CS3. Est-il possible de le faire dans le flash ? est-ce que… ou n'importe qui est heureux de les convertir pour moi s'ils ont les outils et si je te les envoie ?

Convert EBCDIC to ASCII

Hi all,
We are using XI 3.0 SP 10 and I have a scenario where I only need to retrieve a file (via FTP) and deliver it to a file share inhouse. There is no need for any mappings etc. But the file Iam retrieving is in EBCDIC and I would need to convert this into ASCII when delivering to fileshare. I have set up the communication channels and this works fine. But what would be the easiest way to convert the EBCDIC file to ASCII?
Regards,
Fredrik

Hi Fredrik,
There is an alternate way of acehiving the same using a java program in the operatingsystem command option of File adapter.
Steps:
1. Write a java program to read EBCDIC file and convert into ASCII file(Using codepages).
2.Create a jar for the above program and store it in a server directory.
3.Write one shell script/batch file call the java program and send command line parameters as filenames.
4.In XI File adapter -Operating system command use the Shellscript/Batch file name (Complete path)and give %F for filenames
Eg. /usr/sap/serverdir/convert.sh %F %F
For more details refer the following link:
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm">XI File adapter</a>

Convert unicode to ascii

I have a unicode like "100", which represents ASCII code: "d"
I can simply convert unicode to ascii code if using Visual Basic function: chr(); but how can I do the same job under cocoa ?
thank you.
G5 Mac OS X (10.4)

Well, if you wanted to create a single-character NSString from an integer value, you could do something like:
unichar oneChar = 100;
NSString *oneCharStr = [NSString stringWithCharacters:&oneChar length:1];
What are you trying to accomplish?

Convert char to ascii

Hello,
How can i convert a char to ascii, and ascii to char??
thanks,
Riss

its quite simle really.
// 199 is the ascii value for 'w';
char doubleU = 119;
System.out.println(doubleU);
//or
String doubleUString = "119";
doubleU = (char) Integer.valueOf(doubleUString).intValue();
System.out.println(doubleU);
//to get the ascii value of a letter
System.out.println(doubleU);
doubleUString = "w";
doubleU = doubleUString.charAt(0);
System.out.println(doubleU);
System.out.println((int) doubleU);
