Hex values in byte

I need to encode a message string that consists of a byte array to be sent to a device.
Two of the items are numeric values that are to be represented as hex 0x00 - 0xFF.
This needs to be placed into a single byte.
My question is this, can I use a short for my numeric value and then cast that value to byte like this
short s = 200;
byte b = (byte)s;
With this fill the byte with the hex value 0xC8
If not, how can I do this?
Thanks

byte b = (byte)s;Yes and no. You'll get the byte 0xC8 into b that way, but its numerical value will be -56, not 200. Since you want an array of bytes, I assume this won't matter.
But why do you want to do it that way anyway? And why a short, not an int?
And by the way, 0xC8 is also a "numeric value".

  • How to sum space delimited hex values in a string, and do other stuff?

    Hello
    I am trying to write a Bourne shell script that takes a non-constant-length character string as input, converts each character to hexidecimal value, sums each value, takes the two's complement of the sum, logically ANDS it with FF, and if any of the resultant "nibbles" are a-f, print/save that nibble as A-F, for later display as a two-character-long character string
    For example, assume a variable (as in non-constant) length variable $A
    A="w04:0;2"
    the road that I started down was to define
    B=$( echo $A | od -An -t x1 -N"${#A}" )
    # for this example, $B=77 30 34 3a 30 3b 32
    It's the middle part where I need some magic. What I want to do is add the whitespace-delimited hex values of this string, for this example
    C=77+30+34+3a+30+3b+32
    so for this example, $C=1b2
    then take two's complement of $C; for this example, $TWOS_COMP=ffff ffff ffff ffe4e
    and logically AND it with FF; for this example, almost-final answer is 4e
    then save final result as uppercase character string variable (for this example, variable's contents would be 4E)
    Is what I'm trying to do intuitively obvious to any of you gurus out there, that could rattle off an answer? I'm okay with trashing my approach thus far and trying something totally different, within the constraint that it run inside a Bourne shell script.
    Thanx in advance, if anybody can help!

    I've made progress. I've converted each character of a non-constant-length string $A into a space-delimited string of hex values, added them up, and retained the least significant byte (i.e., the 8 least significant bits). Here's how:
    B=$( echo $A | od -An -t x1 -N"${#A}" )
    D=0
    for C in $B; do
      C=0x$C
      D=$(($D + $C))
    done
    D=$(($D & 16#FF))
    D=`echo "ibase=10;obase=16;$D" | bc`
    The missing piece now is how to take the two's complement of $D. Anybody out there with any ideas on how to handle the two's complement piece inside a Bourne shell?
    Thanx

  • READBINARY and HEX values.

    I have a small JPG that I've converted into a RAW RGB format.
    I've tried every combination of TOBASE64(), FORMATBASEN(), and
    TOSTRING() that I can think of but still can't read the values.
    For instance, if I open the .RAW file in PaintShop Pro, I can
    see that the first pixel at (1,1) has an RGB set of 84,82,73. If I
    open the JPG and look at the same pixel, the same RGB value of
    84,82,73 which is kind of brownish grey.
    If I open the .RAW is a hex editor, I can see the hex values
    as "84-82-73-82-88-79-8c",etc. So, I would like to use
    CFFILE/READBINARY to read the first set of RGB values. In reality,
    I would like to read all sets of RGB values, three at a time.
    How is this done?
    Gracias.

    Have you had a look at Christian Cantrell's method of
    Using
    ColdFusion to Write Out Binary Data. You could then just put
    the number of bytes in place of
    arrayLen(pic), remembering that one RGB set is 3 bytes.

  • Possible to supply a hex value to solid's color property?

    I know the AE Scripting Guide specifies that we have to supply an array of RGB values if we wish to change a solid's color property.  I'm just curious if it is possible to supply a hex value in lieu of an RGB array.  Does anybody have any experience with a work around?
    Thanks!

    Dan,
    Just wanted to add that I didn't realize your function assumed the hex color value would be passed in as `0xFFFFFF`.  My data was passed in as a string such as `FFFFFF`.  To fix, I just added one line:
    function hexToColor(theHex){
      theHex = parseInt(theHex,16);
      var r = theHex >> 16;
      var g = (theHex & 0x00ff00) >> 8;
      var b = theHex & 0xff;
      return [r/255,g/255,b/255];
    Thought this might help somebody who had the same data coming in question.  Thanks, again for the help.

    Can any one have a idea what is goning wrong?

    All I want to know is how to use the RE class tocheck

    Correction:
    If the data is numeric, it can be matched using a hex,
    or octal representation for the regular

    matched with either of the following regexes (hex,

  • Converting a hex String to its corresponding hex value...?

    Yeah, I'm having quite a bit of fun guessing this one... :p
    I have a string of n characters and have used Integer.toHexString( ( int )str.charAt( i ) ) to convert each character to a string representing its hex value. Now I need to USE that value for bit-wise operations, like, say, applying the AND, OR, etc. operators...
    Example:
    hexvalue &= 0xC000FFFF; //the second value is the one extracted from the string;
    How can achieve this...? Any help is greatly appreciated... :}

    Since a Java char is numerically a Java short, you can apply bitwise operators to chars directly - the conversion to hex simply changes the way that the char is viewed; the result can also be viewed as a number in other bases.
    For instance, the char 'A' can be also be represented as any of the following values:
    binary - 1000001
    octal - 101
    decimal - 65
    hex - 41
    Likewise, 'Z' can also be viewed as
    binary - 1011010
    octal - 132
    decimal - 90
    hex - 5A
    "Anding" the letter 'A' with 'Z' ('A' & 'Z') or doing the same using any of the other representations will result in (binary 1000000, octal 100, decimal 64, or hex 40) - the bit pattern is the same, only the representation of the result varies.

  • Adobe Illustrator CC 2014 not allowing me to change colors by typing in a precise hex value.

    JWoo,
    What happens if you use the Web Safe RGB from the Color palette flyout and insert the values there?
    For failures in general, you may try the list.
    The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
    If possible/applicable, you should save curent artwork first, of course.
    1) Close down Illy and open again;
    2) Restart the computer (you may do that up to at least 5 times);
    3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
    4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
    5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
    Even more seriously, you may:
    6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

  • How to add HEX values in a Report.

    I have a special requirement. I need to add hex values in a report. To be specific, the special HEX characters: 0D 0A 0C 0C, has to be added to TOP of PAGE event.
    Drawing What I want will be something like that:
    CR/LF FF/FFABCDEFHGIJKLMNOZVCXC 
    This is a Report that has to be send to the spool. Once in the spool will be converted to TXT file. I created a small code using print control function but still It is doesn’t working.
    I defined a print control ZPAGE as ‘0D 0A 0C 0C’.
    Any idea how to do this?.
    ** This report doesn’t include the Top-of Page event.
    ** Example Report.
    REPORT  ZCAPRTHEX2 NO STANDARD PAGE HEADING.
    Data: String1(120) type c value 'ABCDEFHGIJKLMNOZVCXC'.
    WRITE : /.
    PRINT-CONTROL FUNCTION 'ZPAGE'.
    WRITE : string1.
    This is what I see in SP01 as HEX View
    ABCDEFHGIJKLMNO ZVCXC #ZPAGE

    If you download spool to file like that, you are still getting the spool in SAP format, it's not going to have the hex chars. You need to print the file by clicking on printer button. SAP generates file in printer readable format and send it to printer. I'm refering to that file.
    Ask your basis folks to write the spool output reqest file to a file instead of sending to the printer. Open that file in hex viewer.

  • How do I read a hex value and then convert to the binary equivalent?

    I am reading hex values from a register on my unit under test. I only want to monitor certain bits in the hex value to check a status. I have everything down to run the program except how to read my hex values in binary form. Any suggestions out there?

    If this is just a matter of display, then right click and choose "Format & Precision...". Beware, this works only with integer indicators (I8/16/32 and U8/16/32).
    If the problem is to extract a bit value in a specific position, then go to the "Advanced >> Data manipulation" sub-palette where are all bit manipulation functions (rotate, shift, split...).
    Don't forget either the logical functions (And, Or...) in the boolean sub-palette, where is also the "number to boolean array" function (to be used in conjunction with an index array node).
    Another option is to use string conversion functions, in the "String >> String/Number conversion" sub palette.
    Have a look to the attached image.
