• How to convert the Ascii string containing hex to hex string info?

  Dear all,

  I am busy doing a control/reading program for pumps of ISCO.

  Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

  Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

  So to summarize:

  I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

  The VI is attached.

• Convert ASCII characters in hexadecimal equivalent code

  Hello

  I'm trying to convert special ascii characters that are read from a serial port, a type of data that I can handle. To create this scenario, create an empty string constant, then make a right click on it and change the type of "Hex". Now, enter a value in this document, said 287F. If you right-click again and change the "Normal" view, you should see this value "(", which are special ascii characters."

  What I'm trying to do is to convert the incoming data in a format where I can manipulate the data to read the binary equivalent of these data. For example, for incoming data of '287F', I want to be able to convert "0010 1000 0111 1111".

  I was not able to find any function that would transform this data type. I forget something that is very obvious? Or is it not possible to do in Labview. Please notify.

  Thanks in advance.

  If it is always exactly 2 bytes, catalogued at U16 and a format string as a binary file or set the display of the U16 in binary format.

  

• Convert double IEEE 754 (hex?) table

  Hello

  is there a built-in Labwindows to convert table of IEEE 754 double (or hexagonal?, I'm not sure)

  Like this:

  Double Hex table

  40 00 00 42 20

  40.5 00 00 42 22

  40.8. 33 33 42 23

  I thank you,

  (PS: the hexagonal arraies above are calc by Type-Casting in Labview)

  As far as I know, there is no built-in LabWindows function to do this, then you need to use what exists in C.  The two ways that I know is to use pointers to mount the pointer to the float value as a pointer to an unsigned int and then retrieve the value as such:

     float f = 40.0f;
      unsigned int u;
  
      u = *((unsigned int *)&f);
  

  The other way is to use trade unions, which could be more convienent if you do this a lot.

  union ex32
  {
      float fval;
      unsigned int uval;
  };
  
      float f = 40.0f;
      unsigned int u;
      union ex32 t;
  
      t.fval = f;
      u = t.uval;
  

• bt_gatt_write_value_noresp HowTo convert ascii uint8_t string *.

  my C knowledge is very poor and so I have a question.

  use case:

  Crystal APP

  connected to a custom equipment

  Find services and connect to services: OK

  Characteristics of the found Services

  Record the reading for the notification Service: OK - all notifications are coming through

  now, I also have to WRITE a feature using

  int bt_gatt_write_value_noresp(int instance, uint16_t handle, uint16_t offset, const uint8_t *data, int size)
  

  This is the command that I want to write to the device as a String:

  "$HTMEA, 1, 7 * 7F\r\n".

  How to convert this string ascii uint8_t *?

  and what is the length (size)?

  using the. toAscii() I take a ByteArray and there is a. constData() which gives me a char *- but it does not help.

  looked at BT THE Primer, examples of applications and blogs, but did not find an example where a QString will be converted and sent to the device.

  the other way back to recall notice where the uint8_t * was transformed into a QString, I found in the sample application and this heart rate monitor market.

  thx for help

  overdraft.

  First, I had to get the hexadecimal value of my request chain.

  QString theRequest = "$HTMEA,1,,7*7F\r\n";const int characteristicLen = theRequest.size();uint8_t *characteristicBuffer = (uint8_t *) alloca(characteristicLen + 1);QString theRequestAsHex = theRequest.toAscii().toHex();
  

  so I found some utilities BT THE sample applications to help me turn this into uint8_t *.

  Utilities::hexToIntArray(theRequestAsHex, characteristicBuffer);
  

  The following methods of the utility:

  const QString Utilities::HEX_CHARS = QString("0123456789ABCDEF");
  uint8_t Utilities::hexToInt(QChar c1, QChar c2) {
      c1 = c1.toUpper();
      c2 = c2.toUpper();
      uint8_t result = 0;
      result = HEX_CHARS.indexOf(c1) * 16;
      result = result + HEX_CHARS.indexOf(c2);
      return result;
  }
  void Utilities::hexToIntArray(QString hex_string, uint8_t* output) {
      const size_t numdigits = hex_string.length() / 2;
      for (size_t i = 0; i != numdigits; ++i) {
          output[i] = hexToInt(hex_string.at(2 * i), hex_string.at(2 * i + 1));
      }
  }

• hexadecimal to ascii convert function - I need null result for others

  Hello

  I have a coloumn which is vachar2 and it has numbers hexadecimal ascii codes together. I need to convert strings in ascii codes, but keep numbers.

  I can convert hex ascii as below

  Select utl_raw.cast_to_varchar2 (hextoraw ('4B414C414E42494C4749')) of double;

  Select utl_raw.cast_to_varchar2 (hextoraw (EXCHANGE_ID)) from myTable;

  results;

  --------

  

  Result has many characters that are corrupted due to the number who have coloumn. I only need the significant values like "Kalanbilgi" or "Arayanibil".

  Your rules, but this always guessing a bit, you can get on the right track. I thought that...

  • If the passed value contains one of the letters A through F, it must be hex and must be converted to ASCII.
  • If it contains an odd number of digits, it cannot be a string of two-digit hexadecimal codes, so it must be a number.
  • If the converted ascii text contains characters but letters and numbers, it is not valid, so it takes a number
  • Otherwise, it is an ASCII string.

  With this set of rules (add or change the way you want) we can do this:

  WITH testdata (val) AS

  (SELECT "905071917837" FROM DUAL UNION ALL

  SELECT "905394609716" FROM THE DUAL UNION ALL

  SELECT "905558434737" FROM THE DUAL UNION ALL

  SELECT "90555843473" FROM THE DUAL UNION ALL

  SELECT '4B414C414E42494C4749' FROM DUAL UNION ALL

  SELECT '2444' DOUBLE UNION ALL

  SELECT '41726179616E6942696C' OF THE DOUBLE

  )

  -End of the test data-

  SELECT the val

  CASE

  WHEN val! = TRANSLATE(val,'9ABCDEF','9') THEN ascii_val - contains the letters, must be hexagonal

  WHEN LENGTH (val) / 2! = TRUNC ((val) LENGTH / 2) THEN val - an odd number of characters, must be a number

  WHEN TRANSLATE (UPPER (ascii_val),'* ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 ',' *') only IS NOT NULL THEN val - ASCII contains illegal characters, should be in number

  Of OTHER ascii_val

  END val_out

  (SELECT TRIM (UPPER (val)) val,

  UTL_RAW. CAST_TO_VARCHAR2 (HEXTORAW (Val)) ascii_val

  OF testdata)

  Something like that should do the job (even if you have still some false positives), but the difficulty in the interest of your design, if you do not have to guess what the content of this average field in the future.

• How to convert an ASCII integer?

  Here I am trying to send the number 1000000 microcontroller by UART and I get the ASCII in labview. But I would get 1000000 exact in labview also. So I try to convert ASCII in full, but I'm unable to do so.

  Hello Marsu,

  Please don't feel bad. Smercurio and all the other experts try to make us do things on our own. This will make us experts in labview. This is why he told you to go through the tutorials. I've heard this type of advice (sometimes they scold us) so many times. Still Iam hearingit's our fault if we won't go through the tutorials properly. Don't get excited.

  In addition, the question is relatively clear formulated and almost makes me assume that the OP did not bother to look a solution himself. As the OP receives a string, it would be logical to look at the range of string for a function to do what he wants. And inside this palette, there are magically a range of Conversion/string number, that sounds almost like it could contain at least a function that could do the right thing. (In fact, it contains 3 that might work, but I don't know that the OP may find makes the most sense for his races).

• Hexadecimal number to hex string

  Dear moderators of Labview and experts.

  I'm looking for a simple tool, but could not know.

  Could you help me?

  I want to convert a hexadecimal string, Hex number unchanged.

  I mean digital Hex display shows E8 and I convert it to a string and I have Open indicator string Hex window and get the same answer E8.

  Someone knows how to do?

  I thank very you much in advance!

  cast will do what you want.

  

  (Make sure that digital is U8 and the string is defined to display hex.)

• ASCII to I16

  Hello

  I am reading data into a small robot and to convert data in a number of I - 16.   I have attached a photo of the piece of code which I am referring.  Often the numerical value of the returned ascii data is 255, which is not correct (I've been running tests so that I should get a small negative values).  It seems to be something wrong with this piece of code? (I checked the discussion forums and other links on ni.com and it seem to be correct..)

  In addition, if there is another way to convert ASCII into I-16 who works or which is easier, please let me know.

  Thank you!

  
  

• Display the exact string of the file as a hexadecimal display data

  I'll send control messages via a serial port, which are built in a series of bytes.  Currently, I have all these messages in an excel file which is 8 columns of 224 lines.  The messages are the exact hex display, I need for my program works.  To check my installation, I tested a few messages by manually typing in messages using a string constant and the value display hexadecimal and everything works well.  How can I get the strings in my file to be recognized as they use hexadecimal display.

  Thanks for your suggestions.

  So if I understand, you read an ASCII representation to hexadecimal format of the command strings.

  You must convert ASCII bytes, then the chain, in this way:

  

  The entrance on the left string must be read from your file, of course.

  Notice that the representation of the integer constant must be U8.

  You don't need the Trim function spaces if you are sure that the string does not contain additional characters beyond the last hexagonal number.

• A secret shared 20 bytes works with GBLink v4?

• Tecra M2 does not start - the power light AC blinking orange

  Someone at - it a list of codes for the Tecra M2 flash.
  My friend has a laptop that does not start at the top. the AC power LED flashes orange. a long, short, long, short, long, short, long, short.

  I checked the battery and reinstall the RAM.
  Any IDE?

  Hello

  I agree with go.
  The ASP would be able to tell what means error.

  Usually means short and 1 long: 0
  So the error must be: 1010 1010
  Due to the last significant bit (LSB), to be read by behind:
  So it now means: * 0101 0101 binary *-> it must be converted to hexadecimal-> * 55 Hex *.

  Then, you will get a hex code.
  But unfortunately, I m not very well which could mean this code

  So ask ASP for help!

• How to display data series changed after each step in labview gui, that is to say after the match point fantasy, after substring etc.

  Hi, I have a labview GUI that receives data serially through VISA and basically chops to the strings and realize games until I have values that I'm looking for. I have then convert Ascii string in decimal and feed the new values to a waveform. However, I discovered that some of the output values are incorrect. I checked this by pulling data through Realterm.

  Is it possible that I can see the modified data after each step in the user interface so that I can find where the problem is? I created indicators after each step, but they do not display data, I guess that its because the data is moving too quickly.

  I am very new to labview and struggled through every bit of this GUI, as none of you regular posters know. If you can suggest a solution, please know that I will probably ask more fundamental questions in order to implement your solution.

  I enclose my GUI with a screenshot of the same data through the Realterm. Basically any where you see xxxx TR TR or W xxxxW, know that it is the data between them is to say xxxx that corresponds to the data of interest. Everything else is ignored.

  I suspect that the problem lies in the string to decimal conversion and where 3 digit values increase to 4-digit values. That is, all values of less than 850 are correct but it is the maximum value is reached. My values are expected to reach 2500. Any help would be greatly appreciated.

  You have other debugging tools available to you.  You can use the run culminating to slow down the code and show you the data flowing from each wire.

  You can create a Subvi, which takes the data of each wire and written to a log file if you can review it later.

  You give not the screenshots to your message.
