Convert hex (or byte?) duplicate

Hallo,

I'm contacting an instrument through VISA controls.

I'm getting a release in the hexagonal form combination of numbers and letters.

the thing is that, with all the formulas that I tried to convert it to a double I failed miserably.

The data card, you gave me, I thought that the following Hexagon should have the corresponding values:

C5D1 (2 octets)-> 26

THIS EF5D of CA (4-byte)-> 957

C4E2 (2bytes)-> 14

Instead, I get a very large number.

could you please tell me how to convert these duplicate?

Thank you in advance,

Thodoros

  • Easiest way to convert Hex in full

    This problem is mainly to do with a hexadecimal string of full conversion.  The device, connected via a series output in the format 0A 00 hex connection, when he looking at in hexadecimal.  The first two digits correspond to the data, the last two are attached to separate data points.  what I'm trying to do is the last 2 digits of raster off so a 2, 00 becomes 2A and 2 then convert to integer format (42).  I came up with a method to do this, but it's very messy and may result in data loss.  I enclose my vi (8.2).  The large integer being subtracted is a constant that keeps rising for reasons that I'm not aware of.

    Another issue which I am coding via is the fact that sometimes a byte slips by, manufacture of 2-00 become 00BB or something of this format.  Is there a way to parse the string, whether the first two digits or the last two digits are valid and then separate the valid string?  In this code, it would be necessary allow the value 0000 to read 0.

    If there is confusion, here are some examples of data inbound and output desired

    0100 - 1

    A 0, 00-10

    0005 5

    000-11

    etc.

    Since you read 2 bytes, looks like you should be dealing with a 16-bit number. Cataloged to U16 rather I32 like you do now. And all of this manipulation of strings give the impression that you have found a string of ASCII characters in the format like '0' 'A' '1' 'B' rather than a string of 2 bytes of ASCII characters 0 and 1 b. Then you can divide the number of U16 and take the higher order byte.

    I can't explain why you would be having a byte per except slip if she has something to do with all this manipulation of strings you're trying to do.  But if it happens again, and you know a byte for each other are always zero.  Just take the high byte and add it to the low byte.  Since one is zero, it has no effect on the other octets.

  • Convert Int to byte array.

    Hello

    I am trying to convert an int to an array of bytes and stumbled upon a solution. However, it is not appropriate for BB/J2ME.

    byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();
    
    for (byte b : bytes) {
       System.out.format("0x%x ", b);
    }
    

    I have converted into loop, but not an alternative to System.out.format () there is no J2ME.

    How can I convert my whole in byte array?

    Thank you.

    Hi guys, sorry for the delay in responding. Basically, I have to send my ACR122U an int on NFC. If int is more than 255 does not in a single byte then I have to represent in an array of bytes, right?

    I think RexDoug is correct also, I don't understand masking and stuff like that. It's something that I've always been conscious of good :/

    Thank you guys.

    Here's what I went with:

      public byte[] intToBytes(int value) {
    
             return new byte[] {
                        (byte) ((value >>> 24) & 0xff),
                        (byte) ((value >>> 16) & 0xff),
                        (byte) ((value >>> 8) & 0xff),
                        (byte) (value & 0xff),
                      };
        }

  • Convert InputStream into byte array

    Hey everybody,

    I really need help with this problem that I can not get rid! I am doing an application that loads an image saved on the BB device and sends it to a server, the problem is we can send only a byte [].

    So I try to apply the following method:

    -Loading the image via the FileConnection class

    -Open an InputStream from the FileConnection said

    -Convert an array of bytes as InputStream

    The code should look like this I guess:

    FileConnection file = (FileConnection) Connector.open ("Original_SealV.jpg");
    InputStream is = file.openInputStream ();

    Byte [] img = null;
    int temp = is.read ();
    {while(Temp>0)}

    Convert bytes here?

    }

    This is the last step I'm missing, I tried several methods, but could not run, so I beg for a bit of the collective wisdom of these forums...

    Could someone help me? I will not forget the congratulations!

    or you can always use the standard API

    Byte [] buf = IOUtilities.streamToBytes (stream);

  • How to convert a single byte in UTF8 characters

    Hello
    I have problem with the export of data to the file with UTF8 encoding.

    I varchar2 columns in the database with NLS_CHARACTERSET = EE8ISO8859P2 (Czech Republic) and I need to export the columns in the file with UTF8 encoding.

    So I need to make a single byte FOR byte conversion multi.

    I tried sql CONVERT (CONVERT ('my_char', 'UTF8') command) in the forms, but without effect. The encoding of the file created is UTF8, but the characters are corupted.

    Registry settings on my client is NLS_LANG = REPUBLIC of AMERICAN_CZECH. EE8MSWIN1250

    Could you tell me some thing how to export data from the column with characters on a single byte of file with UTF8 encoding?

    I use Text_io package to write in the shapefile.

    Thank you

    my last try so if you can afford an empty space in your output file in the fist line. I tested hv it works

    create a foo.txt with empty space and then add the file as a normal procedure or try to re - open the file later and replace the space in the first row using SUBSTR etc etc.

    TEXT_IO has very limited functionality try to package DDE it might solve your problem

    Good luck

  • Problems converting hex to int for the color to the graphics paint method Blackberry 6, 7

    I have to analyze the hexadecimal value say #a9a9a9 of the JSON parser and save to DB.
    In my application, this hexadecimal value must be extracted and converted to color for the color of text using the method of graph paint.

    Used to record in DB data type is string. But I am facing problem when trying to convert the hexadecimal string
    in full. Get exception hexadecimal number value being greater.

    Please help me!

    If your string contains "#a9a9a9", then you should skip the "#".  Thus, the code you need is probably something like:

    Integer.parseInt (hexstr.substring (1), 16);

    I am sure that it doesn't have to be top of the case, but if they always give a problem and you confirm that you are passing in 'a9a9a9', then you might consider making capital letters.

  • Convert Hex Hex display to normal display appears no zeros

    Hi all

    I try to combine a Normal hexagonal display channel indicator

    To do this, I formatted the hexagon in a format where it looks like the hexagon starting again but can enter the normal display string

    for example.

    I start by 00040040

    When I try to put it in my Normal display string I get 40040.

    I added a VI with an explanation and an example - it will be much easier to understand if you have a look at that.

    You can use the method createBitmapFromBytes of the Bitmap class to convert an array of bytes to a Bitmap image. If you know that the image will be in PNG format you can even use createBitmapFromPNG

  • How to effectively change decimal numbers hexadecimal bytes streaming?

    Technical support,

    There is an instrument connected to a serial port on my computer which is streaming 25 bytes of hexadecimal data every second.  After changing the display for "Display Hex" mode, I can now see the hexadecimal bytes instead of Laura.  I use the "Hexadecimal string to number" vi with marginal success.  I mean, that (1) I can't convert the entire hex string at all, and (2) when you use "String subset" to analyze different hexadecimal bytes I'm able periodically to convert a hexadecimal byte to a whole number.  I tried the suggestion of molded type indicated in a previous post on this subject without change of achievement, although I do not quite understand how it works (how to set correctly the type?).  Do I need a buffer to convert continuous hexagonal data streaming?

    I would send my vi, but it is quite simple.  25 bytes of hex data in every second (1 second buffer), Index 0, default U32, sent to an indicator.  At this point, all I want to do is see my data.  I'm using LabView 8.5.1.  Please indicate if I should provide more information.  Thank you.

    If your data looks correct when you set the display string for hex, the 'hexadecimal string to the number"is NOT the right tool (it hexadecimal sat in the format of strings containing ASCII characters 0...) F only). You have a binary string so labeled is the right tool. If you want the first 4 bytes as U32, simply create you a diagram representation U32 constant (the value is irrelevant) and connect to the entrance of type type conversion. The output will be a single wire digital U32 containing the desired output.

    What is in the rest of the string? It cannot be U32 except if there are a few characters to terminate employment. Want to see one of the remaining data? In this case, you will need to tell us the structure.

    So please create a flag for the string of your own, run the VI it contains data, then convert the flag to a constant of diagram (right click on Terminal... change to constant: this way to see what you actually). Now, save the VI and attach it here. Tell us what value you expect. (Things could be a little more complicated if you have BOM with the little rule).

    I have a don't know what you mean by "continuous" data. How much history you want to keep? You want to stream to disk? If you just want to see recent history data, connect to an array whose length desired history.
