• Frequency of calls to control for the FPGA read/write

  Hello

  I use a cRIO-9076 with a module NI 9476 DO spend some faucets. It is sometimes necessary for faucets with a pulse time down to a few ms of impulse.

  The FPGA VI Gets the power tap queries, executes a logic of security, and routes the numerical results for the exits. It gets applications power of the VI on RT target that uses the function ' Read/write FPGA control' interaction programming of the FPGA VI front. The loop on the RT runs with 1 kHz, no iteration is missed. That means, it should be possible to switch the valves with a resolution of 1 ms.

  What I see on an oscilloscope, is that the output digital are high for multiples of 50 ms, the system does not reach the valve for example 80 ms pulse or pulses shorter than Ms. 50 is a kind of limitation for calls of "FPGA read/write control"? I tried both options for arbitration, but it does not help.

  The best knowledge of the limiting cRIO/module/features or ideas? Thank you in advance.

• Cannot access the card reader/writer internal Flash

  After a few updates, I can access is no longer any SD card inserted into the card reader/writer Flash. I tried to use the convenience store but just that said there is no problem found. When I insert the SD card, it appears in the 'control Panel\Hardware and Sound\Devices and printers' as ' Flash Card Reader/Writer "but I am not able to access the card.

  Hi Tim,.

  Was there a card player offered to you via Windows update driver update?

  -You see no drive letter assigned to the flash card while you see for readers in the window 'computer '?

  -What is the error you get when you go to the map?

  I suggest you try to change the drive letter assigned to the card and see if that helps.

  1 type diskmgmt.msc in the RUN prompt or in start search to open the computer management window.

  2. right click on the indicated card device and select "paths of access and change drive letter.

  3. click on change if there is an assigned drive letter, and then change to another letter. If this is not the case, click on add and select a drive letter.

  4 restart the computer so that the changes are applied and see if you are able to access the content in the map.

  For more information: http://windows.microsoft.com/en-in/windows7/change-add-or-remove-a-drive-letter

  Alternatively, you can try to uninstall and reinstall the drivers for the card and see if that makes a difference.

  Visit the website of your computer manufacturer to download and install the latest drivers.

• Difficulty using the binary read/write

  Hello

  The binary read/write function somehow not working properly in my application.

  I have one store a 2D strign binary array. When the user closes the application, the application stores the values in table in the Bin file.

  N when the application starts, it reads the file and displays its contents on the table.

  The system works well if the total size of the content is 3 bytes. But if the size of the content is greater than 3 bytes, the program simply returns a NULL value at first when I read the Bin file.

  How to save:

  Convert 2D in String table using "Flatten the string" fn and to save in a binary file.

  Procedure to read:

  read a binary file. convert the output string table 2D using 'string Unflatten ".

  I enclose my code here. PLS, have a look at it and let me know the cause of the problem.

  Ritesh

  I don't understand why you're flattening of a string, a 2D channels table. It's redundant. You seem to be also the substitution of the default big-endian to little endian byte order. You try to save it in a format suitable for other programs on other platforms?

  If this is not the case, all you have to do is:

• Can not open Illustrator CC 2015, read/write permissions error, but the permissions are set correctly.

  I can not open Illustrator because of this error.

  "To work properly, Adobe Illustrator requires permissions of folder preferences be"read-write..." »

  Link support on the error message suggests to change permissions to a file location that does not exist. All permissions are set to read-write, and no changes have been made since the upgrade to 2015.  Uninstalling and reinstalling did not work.  Very frustrating to pay for a product that I can't use.

  I solved the problem by resetting the permissions of my entire disk (apply to items included...). I still can't explain why it was necessary after the upgrade to 2015 from 2014 CC CC.

• A better way to make a continuous read/write on a NOR-6008

  Hello

  I use a USB of NOR-6008 module and have a loop of the software configuration where I acquire analog signals, digital signals, then, then put a digital high or low and repeat. I use digital multiplex outside the material so that I can use 6 of the analog inputs to read 12 signals. The digital inputs that I have are connected to the buttons on a panel that are used for the entry instead of the screen of the computer of the user. My loop is also to build a buffer zone of all the signals on the analog and digital lines that I read in so I can on average and this process elsewhere in the program.

  The question that I am running is because this loop is very slow and on the final product is performed on a touch screen, XP Embedded PC and just this acquisition loop begins again as much CPU as the rest of my program. I would say that drops of loops on 4 or 5 cycles per second, which means that my update of 2 multiplex signals or longer than a second time. I would really like to better performance and does not use as much of my CPU resources.

  I use a way simple enough to make the loop of the acquisition, by setting the parameters I, reading, deleting the task, defining the parameters DI, read, erase the task and then by setting the parameters, write about it and delete the task, which gives a slight delay and repeat.

  Any thoughts on a better way to start the read/write that what I'm doing?

  I have attached the code examples in the loop of the acquisition that I use.

  Thank you!

  First of all, the best plan is to move the chain DAQmx before the loop to create and use a start DAQmx, then write in the loop, then clear once the loop ends.  This configuration must be done once, not every time you write the channel.  This should speed things up considerably.

• Effective use of the FPGA read/write

  I am writing an application for a CompactRIO real-time and I am looking for ways to simplify my code and reduce the CPU usage. I use FPGA to do much CAN e-mail and signal processing, then I have a VI running on the real-time processor that reads values in the FPGA, does some processing and outputs data in the FPGA. My code running on real-time parallel uses several loops running in a master/slave architecture. A single loop reads all necessary information in the FPGA in indicators and writes the values of the controls in the FPGA. The other loops read entries and manipulate the outputs via local variables.

  My question if it would be more effective to get rid of the loop which is dedicated to the communication of FPGA and has of each loop to read and write directly on the FPGA. If I use a reference block FPGA open and use the reference of the output in several loops, each read/write operation block others until it's over? Each output is changed only in one place in the code, but there are several entries that are used by multiple loops. It is even more effective for each loop of read/write for the FPGA on request? How will this affect determinism?

  Thank you

  Jon

  Jon,

  Read/write controls is not deterministic, but I think that your previous method should work just fine, as long as you have that unique writers. If you have multiple writers, you start affected by race conditions.

  I don't think you will see a significant improvement in the performance/CPU in the alternative method. You would see big performance gains if your master loop reads more slowly indeed, but it's always a compromise.

• Extension to make the file read-only accessible in writing

  I found an extension for Jdeveloper make a file read-only available in writing. I followed him to the page:
  
  http://www.Oracle.com/ocom/groups/public/@OTN/documents/WEBCONTENT/130355.XML#file.writable
  
  who has a download link to:
  
  http://www.myjavaserver.com/~rajvissa/writable.10.1.3.zip
  
  The file has not been found. Anyone know where I can get this?
  
  Thank you

  I assume that the server is offline.
  Are you sure you want to use an extension for jdev 10.1.3?
  If you are using a version of jdev other then 10.3.1 this extension does not work.

  You can easily this archive by using the tool external jdev and add a command shell with the file selected as a parameter...

• Need a bit of help with the string read/write DLL

  I have a DLL that communicates via RS232 with some instruments.

  From 2 numbers (parameter number and a number of processes) the DLL will communicate and extract the values.

  I managed to put in place the DLL to get words, characters, long and floats (single precision).

  Now, it is the documentation that accompanies it for strings:

  

  ReadString asks the DLL to get the data of the instrument, if succesfull I have others on call GetString to get the string memory.

  I have a few questions:

  -The values of her star (*) are pointers; As I understand it that it points to a place of memory where the value is stored, is - that correct?

  -How do I know if I pass the value to the DLL, or read? For example with GetString Im not sure if

  I should pass the length of the string to the DLL or if it is read

  -How to get the character returned in a string; IM assuming I need to find somewhere a byte array.

  Now I can also write strings:

  

  As a matter of f:

  -Should I add NULL at the end of the string, or labview does by default?

  My procedure is now: read the input chain, reduce it to the size of the specified string (this is constant according to the setting of the instrument), converted to a byte array and replace the last element of the array with 0 (Null).

  However, the DLL entry expected a character, that I should get in the DLL?

  They can be pointers or buffers. Which of the two is ambiguous in the syntax of C. However, in your case I suppose that piMsgId and pcLen be a pointer to a unique value and pszDest a string buffer.

  -How do I know if I pass the value to the DLL, or read? For example with GetString Im not sure if

  I should pass the length of the string to the DLL or if it is read

  Description is not really clear however most of the C API require today the length of the allocated buffer at the entrance to make sure that they don't overrun the buffer length. They may or may not change this value before returning to indicate the amount of data they actually informed. The pcLen parameter passed by reference probably indicates that this function does this way.

  -How to get the character returned in a string; IM assuming I need to find somewhere a byte array.

  It is not necessary. You can simply set the parameter to a string and must be passed as a C string pointer. In LabVIEW 8.5 or more you can also configure to resize this string for the number of characters as indicates it a different setting of the library to compose the node (CLN), in this case your pcLen. 8.5 you can use a table to explicitedly initialization function create a table Bbyte of the length needed, convert the byte array to string and pass to the CLN parameter. LabVIEW will return automatically only the part of the string up to the NULL character if a CLN is configured as C string pointer

  Now I can also write strings:

  As a matter of f:

  -Should I add NULL at the end of the string, or labview does by default?

  No! If you configure the parameter is a string, passed as a string pointer C, LabVIEW will do it automatically for you.

  My procedure is now: read the input chain, reduce it to the size of the specified string (this is constant according to the setting of the instrument), converted to a byte array and replace the last element of the array with 0 (Null).

  However, the DLL entry expected a character, that I should get in the DLL?

• How to set the width of the column read/write rules?

  Hello specialists of the structure.

  I read a set of DITA files in a specific format to the FM model, and there is a detail that I can't work properly. It should be possible to set the width of the columns in a table, even if the DITA file does not include this information. But the developer Application Structure reference does not give information about what string to pass to the property of fm of column widths. Anyone out there experience in doing this?

  Thank you

  Jang

  I have it!

  Turned out to be simple, but the info was more or less hidden in the Dev Guide of Ref: I already had the line "property column widths fm is the value" but did not know the syntax for values. Turns out you need to delimit the values with spaces, not commas. The parser does not give ANY useful information, simply mentions "somewhere near syntax error" or completely ignores the values that you specify.

  This is how the rule for my properties DITA element works now:

  {'Properties' element

  is fm of table element;

  columns FM property value is "3".

  column and the width of the FM property value is "5cm 5cm 6 cm;

  }

  This works. I earn 10 points to answer my own question. :-)

• Make the form read-only if a field is filled

  Is there a way to do an entire form read-only if a certain text field is filled?  I know that adding a digital signature to a form field, increases the size of the screen, so I prefer not to add a digital signature field in my form.  However, I would like the feature that says after the form is signed, it is read-only.  I have added a text box to the form and tried to add a script that read: if (this.rawValue! = "") (this.access = "readOnly"), but it did not work.  Is there a way I can accomplish this without adding a signature to the form field?

  Hello

  It depends on where you have placed the script, probably the best place is the exit event.

  if (this.rawValue != null || this.rawValue != "")
  {
       this.access = "readOnly";
  }
  else
  {
       this.access = "open";
  }
  

  It blocks only the field that the script is inside.

  You should check the example of Paul LockAllFields, which contains a function in a script object. Whereas Paul calls it a click to a button event, you could call it the output of the particular text field event.

• Make the form read-only

  When I use PDF transformation, the fields that have been hidden in my form are now visible. How can I get an exact copy of the submitted form and do what he read-only?

  If I can save someone the time I spent struggling with this problem, I'll be happy. My script has been called on a change to a drop-down list event. I added the script to the initialize event of fall down as well and now it works perfectly. I tried to fix this in the orchestration, but the solution was in the designer.
