• How to scan a 32-bit unsigned integer to a string?

  I'm trying to analyze a 32-bit unsigned integer to a string value.  I tried to change the format from %d to %u string with no luck.  Maintaining the function return 0x7FFFFFFF (2147483647) when salvation bit is set.

  Can we define the format string such as LabView will show a 32-bit unsigned integer value?

  Thanks for your help,

  Phil

  No, use of %d. If you read these numbers in the %x, they will overflow. In addition, you must connect a constant of diagram U32 'default value' "channel scan" entry, otherwise you get I32, which is inusfficient for your data.

• Re: to turn on the 8 LEDS in binary (base2) of the integer representation unsigned 8-bit. Please help on this! Thnx!

  Hello

  I am a newbie to LabVIEW.Currently I do a few peoblems design for my assignment.

  One of the question that I have right now is to create a façade which has 8 LED indicators and vertical slider control that is an 8-bit unsigned integer. The problem is to turn the 8 LEDs in a binary (base2) representation for the number in the cursor.

  Would be easier to make your Boolean an array, return control a U8 and use the Boolean table number.

• Sending of LabVIEW 8-bit unsigned integers

  Hello

  I send a bytestream of the pixel values in LabVIEW to a C program through TCP connection. I was wondering if this code really sends uint8 data or not, because when I read the data with a console in C application, 3/4 values are zero, as shown in the image below:

  

  and then, when I pass the Boolean expression to send a 32-bit unsigned integer values, only 1/4 values are values null instead. This block is really send uint8 values? :

  

  The VI is uploadet.

  In fact, you always sending 32 bits, because your cast to this type 8-bit data (see red dots).

  You perform the conversion to string within the structure of the case, something like this:

• How to convert an image to grayscale 8 bits unsigned 2D table

  Hello.

  The "Color Utilities' Vision Development Modulde function contains the ColorImageToArray IMAQ, who only has the 32-bit unsigned integer as output values. Y at - it an option to reach a value of the integer not signed 8 bit at the exit?

  Please check this box. what you did is not correct (according to me).

  -Please use formulations appropriate for the types of images

  32-bit color

  8-bit gray

  -Intype casting you use RGB (U32) conversion, Image type should be grey it according to your requirement. If the image is in color, why do you need cast once again he in RGB?

  -After plan color extraction, it is no more color(32bit) of image. There is no point in using image color table. use IMAQ image for table instead.

• c ++ array of unsigned char dll

  Hi TestStand users, maybe someone already had this problem and can help me ;-)

  I'm trying to get an unsigned char out of my dll table...

  my function looks like this:

  typedef unsigned char _U_BYTE;    / * 8-bit unsigned integer data type * /.

  typedef unsigned long _U_DWORD;    / * 32 bits unsigned integer data type * /.

  _BOOL Function1(  _U_DWORD *udwMCM, _U_DWORD *udwSCM, _U_BYTE *ubyINFSEL, _U_BYTE *aubyINFDATA[10], _U_BYTE *ubyEC )
  {...
    gstorm_sCMD_0A_ACK_t *CMD_0A_ACK = (gstorm_sCMD_0A_ACK_t*)ReceiveItem->aubyTelegram;
    *udwMCM = _ean_fSwap4Byte(CMD_0A_ACK->udwMCM, _ean_Unknown);
    *udwSCM = _ean_fSwap4Byte(CMD_0A_ACK->udwSCM, _ean_Unknown);
    *aubyINFDATA = CMD_0A_ACK->aubyINFDATA;
    *ubyINFSEL = CMD_0A_ACK->ubyINFSEL;
    *ubyEC = gstorm_eEC_No_Error
  }
  

  My IDL:

  [entry("")] _BOOL Function1(  [in, out] _U_DWORD *udwMCM, [in, out] _U_DWORD *udwSCM, [in, out] gstorm_eINFSEL_t *eINFSEL, [out] _U_BYTE *aubyINFDATA[10], [out] gstorm_eEC_t *eEC );
  

  In Teststand brings up the following warning:

  «.. . using types not recognized by TestStand.

  «.. . aubyINFDATA is a type not supported. "

  Do I have to use a different data type in IDL? As a LPSTR for strings (const char *)?

  BTW. : I'm using VC ++ and TestStand 2012

  I think about my programming skills!

  It hit me like a hammer

  *aubyINFDATA = CMD_0A_ACK->aubyINFDATA;
  

  won't work for a copy of the table * damnidiot *.

  the solution:

  memcpy(*aubyINFDATA,CMD_0A_ACK->aubyINFDATA,sizeof(aubyINFDATA));
  

  also, I thought that each output in an IDL must be a pointer.

  The tables don't ;-), but if I wanted to I could use

  [out] _U_BYTE (*aubyINFDATA)[10]
  

  but

  [out] _U_BYTE aubyINFDATA [10]

  works great!

  At least my fault!

  Thanks for the help anyway!

• Function call that returns BOOLEAN

  Hello
  
  Could you suggest on below:
  
  21 d
  
  I call the existing function that returns a Boolean value (TRUE/FALSE), in my new code.
  part of the new code should run only when the output more is true.
  
  is logic below... right?
  
  XX_TND_OUT is the existing function
  =======================
  
  IF (in_prod_id) XX_TND_OUT = TRUE
  THEN
  .. . Run my code
  END IF;
  
  
  Thank you.

  Be Boolean you can directly compare the function

  IF XX_TND_OUT (in_prod_id)
  THEN
  ......execute my code
  END IF;
  

  That is to say:

  DECLARE
     FUNCTION iseven (num INTEGER)
        RETURN BOOLEAN
     IS
     BEGIN
        IF MOD (num, 2) = 0
        THEN
           RETURN TRUE;
        ELSE
           RETURN FALSE;
        END IF;
     END iseven;
  BEGIN
     FOR i IN 1 .. 10
     LOOP
        IF iseven (i)
        THEN
           DBMS_OUTPUT.put_line (i || ' is even');
        ELSE
           DBMS_OUTPUT.put_line (i || ' is odd');
        END IF;
     END LOOP;
  END;
  /
  
  1 is odd
  2 is even
  3 is odd
  4 is even
  5 is odd
  6 is even

• SQL type unrecognized: 'unsigned int' when I expand a table in Dreamweaver

  Dreamweaver warning message - "unrecognized sql type: 'int unsigned.
  
  This was happening in Dreamweaver MX and now in CS3. Pages using these tables are not to throw errors when I test them, but whenever I have to expand a table in Dreamweaver, I get these warning messages. Often, I get the same message several times and have to click OK every time before I can move forward. I had earlier OK the warning three times for a table that has a field of type integer and the two fields in total.
  
  Any help would be greatly appreciated.
  Thank you

  Yes, it's a bug.

• Best way to encode several digital inputs of choice / binary indicators

  Hello.

  I need some suggestions.

  We have several libraries API (to control our material) written in C and distributed as a dll.  For many of them, we have a library of LabVIEW VIs wrapping (using the call library function node).

  We have several functions in which the entry (in the original C library) is an unsigned integer, which is supposed to be several flags ORed together (each value one bit).

  I've seen more than one title, that this interface has been transferred to the wrapper live

  1 digital input.  User must understand and use it exactly like the C programmer

  2 try to make more enjoyable - an entry that is a table, which appears on the front panel, as a sort of list box multiple choice of entry (internally in the block diagram that is used to create the correct entry to the C function)

  I think there are others, but this is what I remember right now.  When I saw option number 2 (looking at the front) I thought it was much more enjoyable. clearer and more intuitive (the user can select choice named, no, not strange %valeurs hexa%, etc.).  However when I put on a block and tried to wire diagram, I had to provide an array of numbers; I had no idea what the values were supposed to be.  Option 2 seems so much better for a user interface, but for an API, I think it's actually worse.

  What do you see, if you were a programmer building my functions into your application?

  Thank you.

  Batya

  Since each value is a bit simple, I would say that the wrapper have Boolean values in the connector pane and convert it internally to the correct bit field. Another option is to use a cluster of Boolean, but which may be less friendly to the user of the API. I suggest you do this only if you have several options.

• Subvi in MUX 4 entry and PIN

  I have a problem with a LabVIEW 2009 issue:

  P4.3) create a Subvi than four multiplexed inputs to a single output. The Subvi should have four digital controls floating-point (labeled 1 thru In4), a digital indicator floating point (noted by outside), and a control unsigned integer 8 bit (denoted by Select). If the option = 1, then Out = In1; If the option = 2, then Out In2 =, if the option = 3, then Out = In3; If the option = 4, then Out = In4. (Tip: Select function programming VI > range of comparison may be useful.)

  -Where can I find the entire control 8-bit unsigned?

  -How to do the desired function?

  -How the select function in the indication would be able to help at all?

  I do not fear responses that force me to think. I am trying to learn this stuff.

  Any help would be greatly appreciated. Thanks, Matt

  Make a comparison on the U8. The result of the comparison is a Boolean value. Wire output for Boolean input select.

• Unable to replicate the frations seconds when you read a timestamp to a binary file

  I use LabVIEW to collect packets of data structured in the following way:

  cluster containing:

  DT - single-precision floating-point number

  timestamp - initial period

  Table 2D-single - data

  Once all the data are collected table of clusters (above) is flattened to a string and written to a text file.

  I try to read binary data in another program under development in c#. I have no problem reading everything execpt the time stamp. It is my understanding that LabVIEW store timestamps as 2 unsigned 8-byte integer. The first integer is the whole number of seconds since January 1, 1904, 12: 00, and the second represents the fractional part of the seconds elapsed. However, when I read this information in and convert the binary into decimal, the whole number of seconds are correct, but the fractional part is not the same as that displayed by LabVIEW.

  Example:

  Hex stored in the binary file that represents the timestamp: 00000000CC48115A23CDE80000000000

  Time displayed in LabVIEW: 8:51:38.139 08/08/2012

  Timestamp converted an Extended floating-point number in labview: 3427275098.139861

  Timestamp binary converted into a decimal number to floating-point in c#: 3427275098.2579973248250806272

  Binary timestamp converted to a DateTime in c#: 8:51:38.257 08/08/2012

  Anyone know why there is a difference? What causes the difference?

  http://www.NI.com/white-paper/7900/en

  The least significant 64 bits should be interpreted as a 64-bit unsigned integer. It represents the number of 2-64 seconds after the whole seconds specified in the most significant 64-bits. Each tick of this integer represents 0.05421010862427522170... attoseconds.
  

  If we multiply the fractional part of the value (2579973248250806272) by 2^-64 so I think that you have the correct time stamp in C.

• Sort of a group of numbers

  Hi all

  I am reorganizing my digital signals by the presence of a front panel control that allows the user dynamically set the channel.

  On the front panel, I have composed a set of unsigned integer typedef.  I want to sort this cluster in numbers and be able to exploit the case of the label.

  I understand how to assemble digital waveforms with digital subset and add digital signals, but I do not know how to sort the data structure I created.

  I do not know there is an easy way to do this and she escapes just me.  I'm on the right track with my data structure?

  You can use a Cluster for the Array function to get an array of the values cluster.

  You can create a table 1 d of channels where you hardcode the labels.  (There should be ways to get programmatically the labels in a script, but I don't think it's worth the effort).

  If you bundle up your array of numbers with your array of strings so that you have an array of clusters (each element of the array is a grouping of the value and the string), you can then sort the table 1 d.

  Even simpler.  It is not necessary to get the names of the elements of script.  I've added an example VI.

• OR 9401 at starting out a value greater than 4 000 000 000

  I use DAQ Assistant to read linear a NI 9401 moving in a cDAQ 9178 chassis.  On a few occasions, when I load the VI and start logging from the front position there is no movement, the NI 9401 generates the values as high as 4,294,967,241.  He slowly counts down and then when there's actual movement, the 9401starts OR count the position of 0.  On other occasions, it starts normally from a position of 0.  No one knows what means this high value and why it's output?

  A number like who are close the possible extreme values for an I32. I suspect that your negative movement caused a reversal of meter that has been interpreted as a maximum or near maximum negative number.

  You are actually at the limit of 32 (32-bit unsigned integer).  If the movement back would result in turnover between 0 and 4294967295 and slowly down while moving backward.

• USB 6008 DAQ scaling

  Hello

  I use a USB-6008 to read signals from analog voltage to a device I built. The task is configured with a single reading finished with a range of + -10 volts. There is no scaling in the task or in the block diagram, but when I acquire data in a PDM file and view it, I get a load of PieceWisePolynomial scaling properties. I have attached the TDMS spectator to this post.

  Does anyone know where it comes from because I can't explain it.

  Thank you

  The data goes back as an unsigned integer between 0 and 32 k of the ADC on the 6008.

  The scale is to convert this unsignedInt to floating point value between-10 and 10.
