• Binary indicator for digital output device

  This probably simple question for most people, but there is always a first time to do a new thing/thing we have ever done.

  I NI 9472, which is a digital device of the supply, I have no problem to control using LABView to produce the result (line 00000000).  I would also like to have some information on the computer screen using the LED matrix.  I am able to create a binary table indicator, but fail to connect the decimal point of entry to the binary table.

  Please help/provide a few tips, it is appreciated.

• Strange question, while calling the DeviceInfo.getBatteryStatus () function

  I don't know when and how I can post pictures on this forum...

  OK, I guess that this must be a bug in the system, because when I call getBatteryStatus function without USB connection I receive a normal status, however, when connecting to a USB device (include AC, external and computer) I received only a State, 5, an odd number value!

  I need your help, so! ~

  See the API:
  Returns:
  Combination of masks BSTAT_xxx of this class.

  The returned value is a binary indicator pattern. 5 would mean "4 is true, also applies to 1.
  If you need more information about this mechanism, you can google binary indicator.

• How to test the weather device is roaming or not?

  Hi, we have a requriement that we check the weather, that the device is roaming or don't use not rim api.

  so any body can help me please in this area, which has the code to know weather device is roaming or not using not rim api?

  You should check the bitmask returned by RadioInfo.getState (). For example, in this way:

  boolean isRoaming = (0 != (RadioInfo.getState() & RadioInfo.NETWORK_SERVICE_ROAMING));
  

  In addition, pay attenation that are NETWORK_SERVICE_ROAMING and NETWORK_SERVICE_ROAMING_OFF_CAMPUS. I don't know what is the difference and if one of them is what you need. All that I know is the way how to check the binary indicator.

• Use the indicator binary enum in the public Service but allow several indicators

  Hello

  I have a few clusters that contain enums where the user can select a value among many others. However, sometimes these enumerations are binary indicators and I want the user to be able to select more than one indicator at the same time, which will then be DSB. What I usually do is to have a table with the data type as enum, and I simply OR all the elements in the array.

  I was wondering if anyone has a better suggestion how to do that?

  Thank you

  M

  Use a listbox control, and then leave several items to select.  It returns an array containing the indexes of all selected items.  You can use it to find the values of mean to you every element of another table.  Or if the order of the elements in the array is just right, you can make a 2 ^ math function table and add the resulting table.

  

• How the names of variables and units used in the binary output file

  My colleague will give me LabView generated from the binary files (*.dat). There are more than 60 variables (columns) in the binary output file. I need to know the names of variables and units, which I think he has already configured in LabView. Is there a way for him to produce a file that contains the name of the variable and unity, so that I'll know what contains the binary file? It can create an equivalent ASCII file with a header indicating the name of the variable, but it does not list the units of each variable.

  As you can tell I'm not a user of LabView, so I apologize if this question makes no sense.

  Hi KE,.

  an ASCII (probably the csv format) file is just text - and contains all data (intentially) written to. There is no special function to include units or whatever!

  Your colleague must save the information it records the names and values in the same way...

  (When writing to text files, it could use WriteTextFile, FormatIntoFile, WriteToSpreadsheetFile, WriteBinaryFile even could serve...)

• best method to transmit the PPM (servo control) in series-wireless transmitter? (how to combine binary + whole in a single series byte)

  I'm pulling my hair out here... I hope someone can help to guide me in the right direction.  I'm just learning binary and hex, so please forgive me (and correct me!) if I say something wrong.  I have to give credit when it is deserved, because I use info from a post on theautochannel.com to drive this development.

  I try to control a small indoor RC helicopter using LabVIEW and a USB joystick.  I communicate with a transmitter wireless via rs232 (TTL converted), the Protocol is 125000, 8n1. Each image is 14 bytes 2 bytes of header.  I would like to transmit data PPM (pulse position modulation) which is actually just a 10bits (1024 possible measures) range that dictates the position of the servo, for each channel.

  Byte 3 & 4 are channel 1, byte 5 and 6 are channels 2, 7 & 8 CH 3,... and so on until the bytes 13 & 14 which is CH 6.

  Each pair of bytes begins with "00" (binary).

  Byte 3 & 4 should look like "00 00 00 xx xx xx xx xx", where the first "00" is the header, then "00 00" is the identifier of the servo, and 'xx xx xx xx xx' represents the position of the servo. The identifier is actually integrated in the position of the servo, the bits serve a double purpose.

  That's why it all will look like this:

  CH 01:00 00 00 xx xx xx xx xx (position has a valid range from 0 - 1023)

  CH 02:00 00 01 xx xx xx xx xx (range 1024-2047)

  CH 03:00 00 10 xx xx xx xx xx (range 2048-3071)

  etc... If you convert the binary range, you can see how the second half of the bits ID servo are provided by the range of servo.

  I intend by entry VISA to send every byte to constitute the entire frame, and then I will pause ~ 10ms between frames. However, my question is how the hell should I code this? !!  I think I need to write, take 1 CH for example, bytes 3 and 4 together into a string and then split them back hand to be sent as two distinct bytes.  However, I do not know how to mix my header and the first two bits of my ID servo, which is binary '00 xx', with my servo position (which I know I can write in decimal form, as entry VISA will convert it in binary). Any thoughts on the best way to do so, given all this?

  An empty string character likens to a binary "0"?

  Has totally confused everyone?  I really hope not, but I'm pretty tired so let me know if I need to simplify my question.  I hope someone can enlighten me as to the best way to combine the binary constant w modification of decimals (or hex).  And if anyone has thoughts about a good way to organize my vi together, I understand that too!  Right now I'll just use the structures of sequence... I post my code but at the moment, there is not much to look at

  Thank you very much!!

  No, you do not confuse everyone, but I think you might have confused yourself.

  You basically need to do is to create the array of bytes that will be sent, and then use the array of bytes to a string, so you can send it to the serial port. The creation of the byte array can be done in several ways. You deal with 6 16-bit numbers, of which the lower 10 bits are the values of the position of the servo. I don't know what you want on the front panel to look like, but if you have 6 separate (one for each servo) controls with each set having a range of 0 to 1023 (for 10-bit), then you just have to OR each value based on the number of servo. Put all this in a table, add the bytes of the header and the array of bytes to a string allows to get a string that you can send via the serial port. You can also do this in a loop. Joined a VI to show the two concepts. You have not indicated what version of LabVIEW, is 8.2 you use.

• By the way the table of Clusters with binary strings via adapter LabVIEW

  I need to go through LabVIEW adapter table clusters containing binary strings.
  These data will be subsequently stored in the MySQL database.

  I need to force the option "Binary string" for the ValBinary element, even if my output array is empty.

  Is this possible?

  Used versions: TestStand 4.2.1 + LabVIEW 8.6.1

  Attached file: valbinary2.vi containing the clusters of test output array.

  Howdy Jean-Louis,

  My apologies, I'm not quite your question. You're right that LabVIEW does not know that a string is a binary star strong; LabVIEW, chain stores in a format of Pascal, looks like all the strands in the same way. Because TestStand stores strings in the C type format, on the other hand, the null (0x00) characters can be confusing when interpreting strings in TestStand as you learned to understand. That is of course why TestStand offers the feature to interpret strings as binary strings.

  As Sylvie refers to his post, to illustrate his point I created within TestSTand an array of the same type of data customized to store past out of your valbinary.vi of test data. Test patterns, I also edited the outputsome constant values to the cluster VI. (See the following screenshot). Note that the last string (named ValBinary) in the cluster contains a hexadecimal string with a null character that is inserted as the 3rd on-screen character (before the actual end of the string).

  

  Here is a screenshot of the created sequence file that calls the VI and then displays the number of items in the table from the VI to the user.  Note that the Locals.MyTestData table is empty before the execution of the sequence.

  

  Finally, as the execution of the sequence, I opened the Variables pane to view the contents of the Locals.MyTestData table. Here, I have confirmed that the "binary" string of LV was successfully passed in and stored by TestStand.

  

  Finally, the popup message in the second step of the sequence shows indeed a message indicating there were two elements in Locals.MyTestData.

  This sequence has been able to run successfully even without manually specifying a size of Locals.MyTestData beforehand. TestStand dynamically allocated the necessary elements to store the results of test valbinary.vi.

• Error 116 when a string of binary file reading

  I try to use the 'writing on a binary' and "binary file reading" pair of VI to write a string to a binary file and read it again.  The file is created successfully and a hex editor confirms that the file contains what is expected (a header + chain).  However, when I try to read the string back once again, I received an error 116: "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data.»  A quirk I found though, is that if I put "endianness" to "Big-Endian, network order", the error disappears when I use "native, welcome the order" (my original setting) or "little-endian" error occurs.  Did I miss something in the documentation indicating that you can use big endian order when writing of strings, I do something wrong, or is this a bug in Labview?  Because the program that it will be used for is to write large networks, in addition to channels, I would like to be able to stick to the 'native' setting for speed purposes and must not mix "endianness".

  I have attached a VI of example that illustrates this problem.

  I'm using Labview 8.5 on Windows XP SP2.

  Thank you

  Kevin

  Hello

  Please contact National Instruments!  I checked the behavior that you have met and agree that it is a bug, it has been reported to R & D (CAR # 130314) for further investigation.  As you have already understood possible workaround is to use the Big-Endian parameter.  Also, I am enclosing another example that converts the string to a binary array before writing to the file, and then converts to a string according to the playback of the file.  Please let me know if you have any questions after looking at this example though and I'll be happy to help you!  Thank you very much for the comments!

• write waveform in binary

  Hello!!

  I'm trying to store a waveform in a binary file.  I use a labview 'write in the binary file' example as a guide.  My waveform is a waveform that simulated the LabVIEW express menu "waveform simulation."  Well, if I put a graphical indicator, I can see the waveform.  But when I draw a binary file, a very bad image in the form of wave.  Please, see the attachment.  I use the theorem of Nyquist, who say that the sampling rate needs to be 4 times the frequency.

  Please, if anyone knows, post it.

• Binary reading

  Hello world

  I read so many lines and topics related to this BinaryRead I wonder how could I not make it work properly.

  Shrtly I have a LXI instrument I used via TCPIP interface. The LXI instrument is called hollow driver an IVI - COM who use NI-VISA COM.

  SCPI sending back answers without problem. The problem start when I need to read a block of IEEE of the VXI instrument. My driver is based on VISA-COM library and implemented a few interfaces formatted as IFormattedIO488, IMessage, but no ISerial that I don't need to use the interface series. The binary response from the instrument is: #41200ABCDABCDXXXXXXXXXX0AXXXXXXXXX which is made of 1200 bytes representing 300 float numbers.

  To avoid getting the Stop 0x0A character which is part of the binary data stream, I turn off the character of endpoint using the IMessage interface and by setting TerminationCharacterEnabled = FALSE.

  When I read the bit stream of the ReadIEEEBlock is always stop playback at character 0x0A anything.

  I read al of the places in this forum that read binary stream properly by any instrument requires two parameters not only one that I have just mentioned.

  The first, I'm able to control is on EnableTerminationCharacter to FALSE.

  The NDDN is the VI_ATTR_ASRL_END_IN attribute that could be put in a pit ISerial interface only and I couldn't access this interface of my IVI - COM driver.

  As we do not expect to use the interface series with our instruments of TCP/IP what other options I have to allow reading full of the binary stream of bytes, even when a 0x0A is inside.

  Our IVI - COM drivers are written in C++ and use NI-VISA version is 4.4.1.

  Last resort I tried to change the character of endpoints via interface IMessage for TerminationCharacter = 0 x 00 (NULL), but the ReadIEEEBlock always stops the character 0x0A?

  Binary reading is performed inside the IVI - COM driver and if successful the full range of float data points is passed a potential customer request inside a SAFEARRAY * pData object passed as parameter to a public service of the IVI - COM. The problem is that I couldn't read to pass beyond hollow character 0x0A VISACOM interface.

  Thank you

  Hi yytseng

  Yes, I can confirm that the bug is from VXI-11 implementation on instrument LXI himself. Until binary reading all of the previous answers have been terminated by LF (0x0A) character who has the character to end on the device_write function. The VXI-11 specifications are very bad when talking about terminator on device_write then talk to the END indicator on device_read which is not necessarily the same for device_write and device_read. I talked to the guys implementing LXI instruments VXI-11 module and the two agreed to a lack of clarity about the nature of writing and reading processed stop. Ultimately our instrument for reading binary is only the form #41200ABCDABCDXXXXXX format the only character of termination to set TermCharEnabled = TRUE and TermChar = 0x0A, who could be the interface IMessage hollow of the VISACOM interface.

  If the problem was not within the VISACOM, but inside the LXI, VXI instrument - 11 which has send the response of VISA as soon as detected a 0x0A byte value in the bit stream. Now after the BinaryRead change pass beyond 0x0A character but I find myself struggling to read in a ReadIEEEBlock appeal huge amount of float up to 100,000 points data, equivalent to 400,000 bytes for buffers used between instruments LXI and VISA are very small about 1 KB only.

  In any case the solution to my original question was the poor implementation of the VXI-11 instrument on the treatment of device_read termination characters

• convert the binary signal in numbers

  Hi all

  I searched and I can't find a simular solution to this issue, so I hope that somone can help me. It's probably pretty simple, but as I'm new to Labview, it takes time to get used to the programming language.

  I have a rotary switch with 16 positions made-to-measure. The valve has 5 inductive sensors, mounted on a turntable of the holes drilled for the positions.

  With 4 sensors, there is a binary code, created for 16 positions.

  v1 v2 v3 v4

  1 1 1 1 pos 1

  0 1 1 1 pos 2

  1 0 1 1 pos 3

  0 0 1 1 4 pos

  1 1 0 1 pos 5

  0 1 0 1 6 pos

  1 0 0 1 7 pos

  0 0 0 1 8 pos

  and so on...

  The fifth sensor is (1) when the water is rotating and (0) when the valve is in the position.

  What I build with LV is a surveillance system for this valve.

  How can I use the 5 digital inputs (simulated with Boolean switch) in labview and convert a digital indicator for the position of the valve?

  I hope someone can guide me in the right direction with this problem.

  Thank you.

  Here's a solution

• How to ensure that the binary file is stored in the location specified for my DLL files?

  I'm new to computers and has a Dell Inspiron 1545 laptop with a program in Windows Vista Home Premium on a 64-bit platform. I have a thread in my sidebar gadget new MSNBC and the dates for the stories are frozen in December of last year and does not update the current stories. I had no problem with this before and I haven't added or deleted programs because of this problem to the best of my knowledge. I got advice here on the checking of dll files and 4 of them come back with saying error messages and see that the binary is stored at the specified location for debug files. I searched for information help with this and I found a few tips that not saved and re-entered the files, I tried and different versions of the idea, at first it made no difference and then I redid it and it screwed up my weather gadgets so I redid it and they worked very well. I then tried on the DLLs for the MSNBC gadget, but it doesn't seem to change anything, although the gadget to power for the Dow Jones News feed is now screwed up. Is there a site I can go to what can explain the route of binary/specified path or debug file. Save/re seems to be the right path, it affects obviously the gadgets but not as I want, any help in this direction would be appreciated at. Meanwhile I'll go back and try again.

  Hi dumdeedumdum

  
  What are the files dll are facing problems with?

   

  You can perform a SFC scan and check if the problem is resolved.
  To Perform a Scan SFC -
  a. click Start, click programs, on Accessoriesprincipally made, right click guestand then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on Allow.
  b. type the following command and press ENTER:
  sfc/scannow
  A message appears indicating that "the system scan will start. Be patient because the scan can take some time.
  c. If all files require a SFC replace will replace them. You may be asked to insert your Win7 DVD for this process to continue.
  d. If everything is correct you should, after the scan, see the following message "resource protection Windows not found any breach of integrity".
  e. once the scan is finished, close the command prompt window, restart the computer and check.

• Lost data of binary message J2ME

  I have a MIDlet that works on other devices. To do this, an HTTP POST of binary data on my server.  It follows the Connector.open (normal), HttpConnection.setRequestMethod (), HttpConnection.setRequestProperty (), HttpConnection.openDataOutputStream (), DataOutputStream.write (), DataOutputStream.flush (), HttpConnection.getResponseCode (sequence).   When you run the app on the JDE/MDS, publication data do not appear on the server, even if I see that writing to output stream of the HTTP connection is executed; the newspaper of MDS, it says that the connection to the HTTP request entity section is empty:

  <2009-03-17 16:59:51.874="" pdt="">:[102]:::

  I tried both with the type of content set to "application/octet-stream" and jumped with no difference.  Are there restrictions on the type of content in a post from BlackBerry?  Is there something special about to do a HTTP POST of binary content on BlackBerry?  The content-length header would be necessary?  My apologies if I missed some already documented information.  I saw the other posts on an empty HTTP POST content, but none seems to match my case.  I was able to get HTTP GET, this is the display of binary data, with that I have problems.

  I use JDE 4.0.2 to target all MIDP 2.0 devices.

  I found what triggers this behavior in the simulators.  I had a bug in my code that caused it unwittingly (although permitted by the standard RFC 2616) write a HTTP header with an empty string for a value.  I would say only that it is triggered a bug in the device Simulator that then swallowed this header (which explains why the header was not the newspaper of MDS) and has failed on the output with the HTTP POST data stream.

  Looks like an abstraction of the code triggering the bug:

  // ...String locale = functionThatReturnsEmptyString();// ...HttpConnection hc = (HttpConnection)Connector.open(   "http://foo.com/bar", Connector.READ_WRITE, true );hc.setRequestMethod( HttpConnection.POST );hc.setRequestProperty( "User-Agent", "BlackBerry7290" );// Content-Language header value is empty string!// and apparently never makes it from device simulator to// MDS simulatorhc.setRequestProperty( "Content-Language", locale ); // ...byte[] ba = dataToPostViaHttp(); // my binary POST dataDataOutputStream dos = hc.openDataOutputStream();dos.write( ba, 0, ba.length );// data not truly flushed due to HTTP header with empty string for valuedos.flush(); int rc = hc.getResponseCode();DataInputStream dis = hc.openDataInputStream();// ...
  

  RFC 2616 at http://www.ietf.org/rfc/rfc2616.txt is clear enough that an empty value for a HTTP header is legal in HTTP:

  2 Notational Conventions and Generic Grammar
  
  2.1 Augmented BNF
  
     All of the mechanisms specified in this document are described in   both prose and an augmented Backus-Naur Form (BNF) similar to that   used by RFC 822 [9]. Implementors will need to be familiar with the   notation in order to understand this specification. The augmented BNF   includes the following constructs:
  
     ...
  
     *rule      The character "*" preceding an element indicates repetition. The      full form is "*element" indicating at least  and at most       occurrences of element. Default values are 0 and infinity so      that "*(element)" allows any number, including zero; "1*element"      requires at least one; and "1*2element" allows one or two.
  
     [rule]      Square brackets enclose optional elements; "[foo bar]" is      equivalent to "*1(foo bar)".
  
  ...
  
  4 HTTP Message
  
  4.1 Message Types
  
     HTTP messages consist of requests from client to server and responses   from server to client.
  
         HTTP-message   = Request | Response     ; HTTP/1.1 messages
  
  ...
  
          generic-message = start-line                          *(message-header CRLF)                          CRLF                          [ message-body ]        start-line      = Request-Line | Status-Line...
  
  4.2 Message Headers
  
     HTTP header fields, which include general-header (section 4.5),   request-header (section 5.3), response-header (section 6.2), and   entity-header (section 7.1) fields, follow the same generic format as   that given in Section 3.1 of RFC 822 [9]. Each header field consists   of a name followed by a colon (":") and the field value. ...
  
         message-header = field-name ":" [ field-value ]       field-name     = token       field-value    = *( field-content | LWS )       field-content  = 
  

  [Note that the 'value' field is explicitly as an option with the hooks in the production of "message header" and that the "*" notation is used in the production of "value field", indicating that it may be explicitly zero cases of 'field-content'.]

  So I have this part of my code working now, but I would say that this indicates a bug in the software of simulation and may be combined in the combined software as well (haven't tried).
