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...

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..

How do I convert the ASCII character % which is 25h to a hex number. I've tried using the scan value VI but get a zero in the value field.

You can use String to Byte Array for this.

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:

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.

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.

Does anyone have any ideas. I did see a similar post which recommended setting
the weblogic.webservice.i18n.charset="UTF-8" system property, however I already
had this set and it makes no difference.
Anyones help would be much appreciated.
Cheers
Andy

Hi Andy,
The weblogic.webservice.i18n.charset is valid for both WLS v7 & v8. The
API using the BindingInfo class is for WLS v8.
I've attached a simple method (there are many ways to do this) that you
can call to print out the hex values in your stream to help troubleshoot
the problem. If you could create a small reproducer for our support
team, that would be a big help.
Thanks,
Bruce

I am using WLS 7 sp2. I had already set the weblogic.webservice.i18n.charset system

is a valid feature of wls7.
The docs you pointed out mention using the BindingInfo class on the client, but
again I think this is wls8 class, and isn't included in wls7.
Any further advice/assistence would be much appreciated.
Cheers

Hi Andy,
The error text says it; the US-ASCII character is invalid. You might
look over the information about character sets and encoding in the docs
[1]. Did you try setting the weblogic.webservice.i18n.charset="UTF-8"
property on the server side? Java character encoding is a one of the
engineering wonders of the world :-)
What version of WLS?
Thanks,
Bruce

Does anyone have any ideas. I did see a similar post which recommendedsetting
the weblogic.webservice.i18n.charset="UTF-8" system property, howeverI already
had this set and it makes no difference.
Anyones help would be much appreciated.

What about fixing the encoding problem instead? If chars get
lost during
such a transfer
document->script->database->script->browser it's always
an encoding problem somewhere down the road.
The recommendation these days is to use UTF-8, which avoids
most of
these old problems. You just have to make sure that your
documents are
properly stored as UTF-8 in the database and delivered as
such to the
script and the browser, then you don't have to worry about
special chars
anymore.
That's just the general idea. I can't be more specific, since
I don't
know your conversion script or the database structure.

[Solved] no non-ASCII character input in rxvt-unicode

Hello everyone,
For some days now, I can't write any non-ASCII characters any more in rxvt-unicode and rxvt-unicode-patched. Unfortunately, downgrading the rxvt-unicode package doesn't seem to help. To have at least a temporary solution, I'd like to know at least which packages I could try to downgrade as well. Any ideas, anyone?
greez,

When I try to type a non-ASCII-character I get nothing at all. This happens with my custom keyboard layout (modified programmer dvorak) and in some layouts I already tried (us: altgr-intl, ch, de and fr)
When I paste a non-ASCII characters in rxvt-unicode I get
maxmin ~ $ ?
This happens only on my x86_64 desktop which is more up to date than my i686 laptop. (I'm afraid now to do any updates.)
EDIT: I'm sorry, I don't know what you mean with locale settings. What do you mean with that?
EDIT2: Maybe just typing locale in the terminal is what you mean:
maxmin ~ $ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
With other terminal emulators I get sometimes also nothing and sometimes right displayed but wrong interpreted character in vim. I didn't take notes while doing that but I'll try again if needed.

ALV Grid bug when dealing with non-ASCII character

Dear all,
I have a requirement to display user's remarks on ALV. The data element of the remarks column is TEXT200. I know that each column in an ALV Grid can display at most 128 characters. Since my SAP is an Unicode system, I expect that each column in my ALV Grid can display 128 Chinese characters, too. However, the ALV Grid only display 42 Chinese characters at most. Is this a bug in ALV Grid? How can I fix it?
I did a small experiment. The results are listed below. My version is Net Weaver 7.01. The results show that the bug does not exist in ALV List. However, my user prefers ALV Grid, which is more beautiful and elegant.
Type of ALV
Max number of
ASCII character
in an ALV column
Max number of
non-ASCII character
in an ALV column
REUSE_ALV_GRID_DISPLAY
128
42 Chinese characters
CL_SALV_TABLE
128
42 Chinese characters
CL_GUI_ALV_GRID
128
42 Chinese characters
REUSE_ALV_LIST_DISPLAY
132
132 Chinese characters
If you encounter the bug, please post your solution. Thanks a lot.

It looks like limitation of ALV grid cell, which can contain up to 128 bytes in SAP gui.
Your unicode characters are probably 3 bytes each.
Check OSS Note 910300 for more detailed info.
EDIT: Note 1401711 seems to be a correction for your issue It allows to use 128 characters (even if they take more than 128 bytes).

Keystroke return and ASCII character 13 and 10 not working in

I have the following script to opens a web page of my internal telephone switch (all in the local network) and fill in the two fields that come up and needs filled out in order to log in.
tell application "Safari"
activate
open location "http://192.168.1.90/"
end tell
tell application "System Events"
delay 1
keystroke tab
delay 1
keystroke "" -- Note: Username goes here if one is wanted/needed
delay 1
keystroke "XYZ" -- Note: Password goes here if one is wanted/needed
delay 1
keystroke (ASCII character 13)
end tell
All works fine, it skips the first field (the login name is blank). Puts the password in the next field. However it refuses to activate the “log-in” button of the login window (the one that is blue and normally can be done with the enter key).
I tried:
keystroke (ASCII character 13)
keystroke (ASCII character 10)
keystroke return
keystroke enter
Non of them do the job.
Any suggestions please? Thanks.

Consider replacing ...
keystroke (ASCII character 13)
... with ...
tell document 1 to do JavaScript "document.myform.submit()"
... where 'myform' will have to be replaced with the forms' name.
To obtain the forms' name ...
01. Perform a right ('control' if single button mouse) button click on the form based web page. A contextual menu will appear.
02. Select the 'View Source' menu item. A new 'Safari' will appear with the title beginning with 'Source of ...'.
03. Look for a line similar to ...
<form name="myform" action="submit-form.php">
... Note, the name="myform". This is the forms' name. Whatever is between the name="" is what you need to substitute 'myform' with, in 'tell document 1 to do JavaScript "document.myform.submit()"'.
I entered ...
tell application "Safari" to tell document 1 to do JavaScript "document.myform.submit()"
... in 'Script Editor', and visited 'JavaScript Form Submit example'. When the AppleScript code was executed, the web page responded accordingly.
New test of code. With 'JavaScript Form Submit example' again displayed, the following code ...
set tValue to "ChangeAgent"
tell application "Safari"
tell document 1
do JavaScript ("myform.query.value=\"" & tValue & "\"")
do JavaScript "document.myform.submit()"
end tell
end tell
... was entered into 'Script Editor', and executed.
The results were as expected - the resultant web page reported ...
Great! The Form is Submitted Successfully!
Query:'ChangeAgent'
Back
... And, the code was condensed even further ...
set tValue to "ChangeAgent"
tell application "Safari" to tell document 1 to do JavaScript ("myform.query.value=\"" & tValue & "\"; document.myform.submit()")
... producing the desired results.

Unicode value of a non-ASCII character

Hi,
Suppose, the unicode value of the character ् is '\u094d'.
Is there any Java function which can get this unicode value of a non-ASCII character.
Like:
char c='्';
String s=convertToUnicode(c);
System.out.println("The unicode value is "+ s);
Output:
The unicode value is \u094d
Thanks in advance

I have tried with the parameter
c:\ javac -encoding utf8 filename.java
Still I am getting the same print i.e. \u3fIf it comes out as "\u3f" (instead of failing to compile or any other value), then your source code already contains the question mark. So you already saved it wrong and have to re-type it (at least the single character).

Then I studied one tutorial regarding this issue
http://vietunicode.sourceforge.net/howto/java/encoding.html
It says that we need to save the java file in UTF-8 format. I have explored most of the editors like netbean, eclipse, JCreator, etc... there is no option to save the java file in UTF-8 format.That's one way. But since that is so problematic (you'll have to remember/make sure to always save it that way and to compile it using the correct switch), the better solution by far is not to use any non-ASCII characters in your source code.
I already told you two possible ways to achieve that: unicode escapes or externalized strings.
Also read http://www.joelonsoftware.com/articles/Unicode.html (just because it's related, essential information and I just posted that link somewhere else).

Identify InfoObjects that have a non-7-bit-US-ASCII character in key

Hello,
we plan to do a Unicode migration with our BW. SAP recommends, that in order to prevent problems during data extraction all keys of the characteristic InfoObjects should only contain 7-bit-US-ASCII characters.
But we have manually (by hazard) identified some master data records that contain some non-7-bit-US-ASCII characters (like for example "Ö" or "Ä").
We'd now like to check ALL characteristic InfoObjects regarding this issue.
Does anybody know about an ABAP-Report that would ease that task? Generally spoken, the programm should walk through the list of all characteristic InfoObjects and check for each one the master data table for "bad" keys (i. e. keys that contain a non-7-bit-US-ASCII character).
Thanks to any answers in advance!
Best regards,
Philipp

Remove non ascii character

i need a SQL or Procedure that will search non ascii character in data and update the data by removing it
Suppose there is table TABLE1 with Column NAME
it contain number of row and few has non ascii character eg 'CharacterÄr'
My sql or procedure should be able to search 'CharacterÄr' and update the row with 'Character'
i.e. removing the non ascii character 'Ä' from the data

Hi,
Okay, in that case:
SELECT str
,      REGEXP_REPLACE ( str
                      , '[^[:cntrl:] -~]'
                      )   AS new_str
FROM    table_x
or, to actually change the rows that contain the bad characters:
UPDATE table_x
SET     str = REGEXP_REPLACE ( str
                             , '[^[:cntrl:] -~]'
WHERE   REGEXP_LIKE ( str
                    , '[^[:cntrl:] -~]'

Ascii character 129 for newline in the text file

Hi there,
I have java program that makes JDBC connection and reads through a table, write a column in text file, after each column puts delimiter "|"and after each row prints in the next line.
This is the code below.
public void queryRecords() {
         Statement stmt           = null;
        ResultSet rset           = null;
        try {
              stmt = con.createStatement();
              int numRows = 0;
            File file           = new File("/tmp/temp.txt");
            FileWriter writer   = new FileWriter(file, false);
            BufferedWriter pw      = new BufferedWriter(writer);
            rset = stmt.executeQuery("SELECT * FROM mytable");
            ResultSetMetaData rsmd = rset.getMetaData();
            int colCount = rsmd.getColumnCount();
            while (rset.next()) {
                for (int i = 1;i <= colCount; i++) {
                    String st = rsmd.getColumnTypeName(i);
                    if (st.equals("DATE")) {
                        Date d1 = rset.getTimestamp(i);
                        pw.write(d1 + "|");
                    } else {
                        Object o1 = rset.getObject(i);
                        if (o1 != null) {
                            pw.write(o1 + DELIM);
                        } else {
                            pw.write(DELIM);
                pw.newLine();
            pw.close();
             rset.close();
             stmt.close();When i open this Temp.txt file in notepad i see ascii character 129 (rectangular box) instead of the new line. But when i print the file i have each row in a separate line.
Why could this be happening??
Please help...

hi,
Try PrintWriter instead :
File file = new File("D:/testing.txt");
        //FileWriter writer   = new FileWriter(file, false);
        //BufferedWriter pw      = new BufferedWriter(writer);
        PrintWriter pw = new PrintWriter(file);
        pw.print("aaa");
        pw.print("|");
        pw.print("aaa");
     public static void main(String[] args) throws Exception {
          File file = new File("/test/test.txt");
        //FileWriter writer   = new FileWriter(file, false);
        //BufferedWriter pw      = new BufferedWriter(writer);
        PrintWriter pw = new PrintWriter(file);
        pw.print("aaa");
        pw.print("|");
        pw.print("aaa");
        pw.print("|");
        pw.print("aaa");
        pw.println();
        pw.print("aaa");
        pw.print("|");
        pw.print("aaa");
        pw.print("|");
        pw.print("aaa");
        pw.close();
     }hth
