• Schedule iteration five FOR lines inside a timed loop...

  Take a look at the attached code simply run five different but identical TO the lines inside a single loop timed.

  It is interesting to note the timings of each loop iteration FOR: 1,1,2,3,0 milliseconds. The most curious is the moment of the last loop, which for the most part indicates 0! Not only this, if you remove the fifth loop, the fourth a bed 0.

  I can't understand this behavior? Also if LV deals in parallel different loops why should there be a gradual increase in the synchronisation of successive loops?

  Thanks for any help.

  First, 0.2 ms is not statistically significant, you must increase the number of iterations by another factor of 10, at least.

  A quick loop uneducated wait FOR will grab the CPU for much more than one iteration, so regardless of the loop is first online will repel the other loops and run until LabVIEW decides to switch to another loop. The number of cores CPU do you have?

  You can force a release after each iteration by placing a 0ms wait inside each loop FOR. While all time will be significantly longer because of the overhead of increased switching, all loops will be now around the same time.

  You can also read this for more information.

  I don't know that anyone else can provide more details in the jargon of right. I don't know the correct terms for all this.

• Hi - I am trying to draw an irregular shape (series of straight lines) and fill it with the color... How can I do this?

  I need to draw a shape irregular, closed, which is a series of joined lines and fill it with the color, etc., I can only see square, polygon, etc...

  Any suggestions?

  You can set the polygon tool to 3 sides, or use the pen tool.

• VISA series Loopback speed and precision with double loops and a queue

  I'm working on a test of communication between 2 PCs. I test communication series RS-422 ports by using a simple loop. PC2 wrote continuous data at 38400 baud to PC1 (LabVIEW test code is here). PC1 reads the data and writes the data to the same port as soon as possible. PC2, reads the data and compares to what should be returned. I can get the highest speed is a speed of about 37300. Because it is continuous, finally that I get an error because the buffer overruns (read and write buffers are 65KO).

  It seems that VISA writing takes a lot longer than the VISA read. I do read/write asynchronous operations. I've read a fixed amount of data (1024 bytes) and then queued data to write in another loop. My timeout is set to 0.5 seconds, which is much time opf at 38400 baud (4800 bytes/second). I played a bit with these numbers, and they are the best I can get. If I increase the data read to 2 KB, the queue members increase. If I'm going too low, I start getting the data in the input buffer overrun.

  Anyone had experience with this type of test? The code is attached. Please take a look and see if I'm doing things correctly.

  I do not know if this explains a gap between what you expect and what you found in 0.8 seconds, but you have added another level of complication in using the digiboard.  You don't have a real serial port, but a simulated serial port which is hung at the end of a USB bus.  The digiboard software creates a virtual experiences, and so its driver software and firmware on the side of the Board of Directors of the USB bus must manage some translations to go a number of compote, transfer on the bus and decode the Compote number so that it knows which 8 physical ports that it must send the message to.  You can see delays in translation at each end so something in the USB itself Protocol where it needs group information.

  If you have another, a different brand of the serial ports, you can use, you might want to try one of these to see if you get similar or different results.  But I don't think it's a good idea to try to test the limits of a serial communication device using hardware that adds the other layers of the communication protocol and therefore complicated results.

• Series name is not in the series of the line chart that is created dynamically

  I created dynamically a chart series. This works well but the passage of the mouse on the data points shows only the x and the values, but not the name of the series, the legend shows a series of color boxes to match the lines, but no labels displayed for each colored area. Here is my code:

  linechart2.series = [];

  for(a = 0; a < allSettingsArray.length; a ++) {}

  CREATE SEVERAL VERTICAL AXIS

  var verticalAxis1:LinearAxis = new LinearAxis();

  var verticalAxisRenderer1:AxisRenderer = new AxisRenderer();

  verticalAxisRenderer1.axis = verticalAxis1;

  series: var LineSeries = new LineSeries();

  series.verticalAxis = verticalAxis1;

  series.yField = allSettingsArray [a];

  linechart2.series.push (series);

  }

  Each data point is defined in a loop like:

  temp ['gameNum'] = String (a);

  Str = String(attrVal[0]);

  Temp [str] = attrVal [1];

  Then added in the ArrayCollection collection:

  resultArrayColl.addItem (temp);

  Any suggestions, what I'm missing here?

  Mention displayName for the lineSeries.

• Series multi graphic line you are ordering

  I have a line chart with two series and I have a problem of sorting when the data in the second series are not within the limits of the first.

  For example, the blue line represents the series with the smallest value of sequence (10) in this case.

  The red line is the second series with 20 sequence, but the final two points a rendering on the far right, when really belong it to the far left, before the first blue point data - because they are in August 2014.

  

  The problem is compounded when the series is backwards. Note the dates on the x-axis.

  

  The two SQL order by the date value.

  The only mention on the forums I've found is the following, without result

  Bar stacked with several series chart kind Question

  (Note that long lines are through ignore_missing)

  It comes to 4.2.0 but happy to reproduce on apex.oracle.com if you want to play.

  See you soon,.

  Scott

  The solution is to ensure that the first series of the chart contains the range minimum or maximum of the x axis, while the y-axis is null values or zero.

  

  It turns out that the application already had a bunch of NULL values in the blue series to ensure the good spacing in red, otherwise, time scale is all wrong as months as may-2015 are ignored in the plot.

  The query initially ignored these first four blue spots from scratch. Now they are restored, the corresponding red data points can be plotted at the same time.

• How to dynamically display a series in a line chart

  Hello people!

  I have a page with a defined single chart area.  Graphic region contains about a dozen series and all the pretty lines displayed on the pages as you want... it's just that the return of the data process is a bit long.  Even if I know that I can create a view materialized to solve the speed problem what I would really like to do is find a way as my client could really turn the individual series on and outside.

  I wonder if it's possible and if it how can I do?

  Happy trails all... and thank you!

  CJ

  Hi CJ,

  How to approach is to have an area of filter with checkboxes:

  Item1 box [1] Item2 Chceckbox2 Item2 Checkbox3 [X]]

  You could some default to Yes then in the series in the chart add something like [code]: P1_ITEM = "Y" [/ code] and have a dynamic action on change that refreshes your chart when a checkbox is changed

  This is a very basic example, you can take it to another level by allowing your users save the default series, they always want to see at a table, and then have an exists query something like:

  [code] select 1 from my_table where username =: APP_USER and series1 = "Y"; [/ code]

• Why do not perform proxy &amp; line input on a loop?

  Thank you.

  A substitution variable is something that SQL * more (or whatever until you use) replace before sending the block PL/SQL (or SQL) to the database. SQL * Plus has no idea that your substitution variable is inside a PL/SQL block and still less that it's inside a loop. He will never ask a value once and then it will send the block to the database where the PL/SQL is executed to process.

• Implement the LIN Protocol: USB-8476

  Hello

  I have a new project that is to contact a product incorporating the LIN bus. I need to create a program that sends data to the product and receives the response. I thought to use the cable USB LIN or (USB-8476) to perform this function. I've not found a good explanation or examples on the use of this cable and the API that I used. Is there someone who has tested such things? Can you help me to clarify ideas (examples, API, document).

  Thank you

  Hello fishingman.

  For CVI examples that use a LINEN I would recommend navigation examples C:\Users\Public\Documents\National Instruments\NI-CAN\Examples\Borland C\LIN.  Note that this the the installation location on my Windows 7 computer.  It may be in a different location on XP.

  For documentation on the API and implementation of FLAX, I would recommend looking at the user manual CAN which you can access here.

• My automatic doc Photosmart 7525 bin puts a series of long lines on printed copies

  I only get bad copies, no error message

  Copies, copy glass do not have lines

  A ran print and Scan with no luck

  If you get lines in copies by the ADF, but not by the dish, then probably the ADF glass is dirty.

  If you look on the left side of the scanning area, then we'll see the small strip of glass used by the ADF on the Photosmart 7525. Clean this area using a lint and glass soft cleaner.

  Let me know if the lines disappeared.

• ÖAF - loop through a vo and get values of attribute associated with line

  HI people,

  I need code of the OPS to loop through a VO and retrieve the values of attribute associated with each line.

  I use following code in AM after - vo.invokeMethod ("initQuery", params, classes) - line.

  for (loop = 0 int; loop < vo.getRowCount (); loop ++) {}

  Line resultRow = vo.getCurrentRow ();

  If (resultRow! = null)

  System.out.println ("" + (String) resultRow.GetAttribute ("PARTYID"));

  }

  -resultRow - is done with the null value.

  Please share the code to achieve this.

  Thank you

  NGO

  You must call vo.next () to move to the next row, but this isn't a good method.

  You can browse the lines of the vo in two aspects.

  First one uses an iterator that is more reliable because it does not change the current line. You must create the java vo RowImpl file to do this.

  int fetchRowCount = vo.getFetchRowCount();
  voRowImpl row = null;
  if (fetchRowCount  > 0) {
      RowSetIterator iter = vo.createRowSetIterator("Iter");
          iter.setRangeStart(0);
          iter.setRangeSize(fetchBidderRowCount);
          for (int i = 0; i < fetchBidderRowCount; i++) {
              row = voRowImpl iter.getRowAtRangeIndex(i);
               //use RowImpl getters
               Number personId = row.getPersonId();
      }
      iter.closeRowSetIterator();
  }
  

  Second, one is your method proper form:

  for (Row row = rowsVo.first(); row != null; row = rowsVo.next()) {
       Number personId = (Number)row.getAttribute("PersonId");
  }
  

  Kind regards

• Access Protocol remote cRIO

  Currently I have a set-up that allows me to communicate my cRIO remotely using series and TCP/IP protocols with serial modems and wireless routers/bridges. I would like to be able to extend this network using a cellular modem. Is it possible to use my code TCP/IP functionality for communication via a cellular modem or do I need to use features of Service Web of LabVIEW?

  If this is possible using a Web Service, it is possible to have a real time application and a Web Service at the same time works as a starter on a cRIO app? I want the ability to actively pass the communication problems of network protocols.

  Thank you

  Matt

  Hello Matt,

  In General, the answer to your main question is Yes, you can use a cellular modem to the network at a cRIO.  Devices like the BlueTree BT-6600 and Sierra Airlink Raven X have been used in the past with cRIOs.  Using only the TCP/IP protocol with these modems, you must configure the modem to the port of the information forward for the cRIO based on IPv6 on the modem and the designation of the port.  TCP/IP in LabVIEW functions just these two pieces of information, that I could find some information on the use of cRIO and cell phones, but nothing specific about the installer or difficulties you might face.  This kind of network configuration is beyond the scope of what we support here at NOR, so unfortunately there is not much in our database on this subject.

  It should not be necessary to use a Web Service to connect via the modem that you configure ports TCP/IP and IPs correctly.  Web services use the HTTP protocol to transfer data via Ethernet or some physical network layer is in place.  Therefore, the web service is simply a wrapper of information that transmitting on the same lines of communication.  If you can not configure TCP/IP correctly, then web services can still run, but configuration ports and addresses IP is easier with TCP than web services.  In addition, you can run a real-time application and a web service with startup applications.  You could set up an application that includes the web interface screws or configure a web service which includes the action of applying background, but you can not have two startup applications.  If you have configured a real-time application that uses TCP/IP, you can configure a set of background code that uses HTTP instead.  This allows you to switch between protocols using a kind of input control, as a value Boolean network has published a shared variable, select in which case runs.  This implementation is highly dependent on what you're trying to accomplish.

  I hope you find some useful information.  Good luck with your application.
