• Get a hardware trigger on the regeneration of the buffer

  Hi all

  Is there a simple way to get a hardware trigger when AO regenerates a buffer for continuous generation?

  I use NI PCI-6733.

  Thank you

  Michael

  Hi Michael,

  I think it would be the easiest way to use your meter to generate a pulse train that uses the sample AO as its source clock. If you know the number of samples that are in your FIFO, you can specify how many samples to make this high pulse and how to make it low so that the total adds to the top to be equal the number of samples you have in your buffer. Here's a good intro bit to generate a train of pulses with a meter. You can also consult the user manual to the 6733 for more information on the functioning of your meter.

• Trigger on the first attempt

   I'd like some help / advice on my LabView program (attached) please. In the VI, the MyVoltageTask_1 is configured as a voltage signal corresponding to a pressure change inside an enclosed cylinder. The signal is transmitted to the BNC 2110 DAQ board / PCI 6133 DAQ card via a differential pressure transducer. 
  
  Ideally, the program should trigger as soon as I let air into the cylinder and start acquiring data, and stop as soon as its done. However, LabView does not trigger when I let the air into the  cylinder on the first attempt, but if I exhaust the air and let it in again a second time, the program triggers and I can see a graph of the pressure trace. Please let me know if there is something I should / could change in the program to have the program trigger on the first attempt. Thanks!
  

  Have you try to change the slope falling upward? I begin to take a look at shipping the first examples. "" "Open Finder for example of OR and go to hardware input and output" DAQmx "analog measures" voltage. Take a look to the example called "Acq Cont & chart voltage-Int Clk - Analog Start.vi ' I contains the basic structure of what you're trying to reach.

• How to generate a trigger when the arbitrary

  Hi all

  I have a digital output pci card 6534 and an analog output pci card 6723.

  I would like to generate a material long pulse sequence timed. The 6534 has 32 MB memory on board, so it is good to do a long sequence. The 6723 will run out of memory if started at the same time. I would therefore trigger the 6723 at a later date. The boards are connected with rtsi.

  I see 3 ways to do (well that I know how to do, but the first two would be more elegant):

  (1) generate a sequence of digital pulses on ports (i.e. how that), then convert a line of port online rtsi (don't know how to)?

  (2) generate a trigger to the arbitrary point on the rtsi lines (don't know how to)?

  Go 3) with 1) physically connecting a port to a line PFI on the analog card.

  I have not found a way to send a trigger at some arbitrary point with the RTSI. Instead of this I went with solution 3) and related digital outputs analog card PFI channels.

• DAQ trigger on-the-fly reconfiguration

  Hello

  What is the correct way to reconfigure a data acquisition on the fly?

  Every 100 s I'm doing a 2000 point 4-channel triggered acquisition (sampling rate 50000)

  As a function of household, that I also want to monitor the voltage of one of the channels so that every 2 s, I do a single-point acquisition no trigger.

  Since I don't have access to a piece of the DAQ hardware, that I have to share channels between the two tasks of reconfiguration on the fly.

  (the program is too big / complex to post sorry)

  Initialize channels and relaxation (happens once at the beginning of the program):

  

  Get data every 100 s:

  

  Each 2 s get one sample of multichannel without triggering then restore the trigger:

  

  Please could someone explain when I have to use the 'task to start', 'stop task' and 'commit' aid is rather vague and unfortunately I find myself 'hacking' until it works, which is not the way I like to work! I use a USB-6211.

  The above program works OK, but has an intermittent (approx. every 10mins) error on the 'shutdown task"before returning to the trigger. (memory, the description was 'Task not over data acquisition')

  Thank you

  Simply set up once and just start and stop the job.

• The original loop iteration after receiving the trigger of the PXI-6652 pulse

  Hello world

  I apologize if this has been answered somewhere else, but I'm having a hard time finding examples and tired after a long day of work.

  in any case, I use a PXI chassis with a PXI-7854R FPGA Board and module synchronization PXI-6652.  I have the FPGA biphasic pulses being generated at 8 analog channels.  I want to be able to do is to send a trigger (say at 1 Hz) for the PXI-6652, which begins at the exit of the biphasic pulse on the FPGA.  I'm running the FPGA through a host program as the variables on biphasic wave will change based on the current experience.

  So, in short, I was wondering how to generate a trigger of the PXI-6652 pulse and then use this trigger in a host of VI to start an iteration of a loop.  It seems simple enough, so any help would be appreciated.

  Thank you, and I can post the code tomorrow if necessary.

  To answer your second question, Yes, the driver NOR-SYNC 3.3 is available for download and use with LabVIEW 2011.

  As far as use the PXI-6652 to start the acquisition on an FPGA VI, we have enough good examples provided with LabVIEW that will show you how to proceed.  To actually generate a trigger with NO-Sync, there are several examples in the Finder for example of NOR (help > find examples) which send a trigger one of the PFI lines to be used with the other modules.  You can search for OR Sync and they all appear here.  You need this driver installed first before you see anything, however.

  Also, if you look through the viewfinder of the example under Hardware Input and Output > R Series > FPGA Fundamentals > triggers and guard dog, you will find an example of triggering good enough it for use in your FPGA code.

  This example uses NO-Sync to trigger a device of the M series, which is not relevant to what you are doing (he uses DAQmx), but there is a very good example of generation OR-Sync trigger here who I think can help.

• input analog trigger on the door of the meter to measure the frequency of generation

  Hello

  I want to measure a frequency on the analog input, but it doesn't seem to work.

  I'm trying to work with DAQmx with the use of the ansi c standard.

  The first step, I've done was acquiring information on the analog input. With the use of a simulated device, it shows a sine wave on the entry.

  My next step is to generate a trigger for the meter signal, but this doesn't seem to work.

  I don't see how it is possible to connect the trigger on the entrance to the analog meter.

  For the creation of the analog input and relaxation, I use the following code:

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
  DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","",DAQmx_Val_Cfg_Default,-3.0,3.0,DAQmx_Val_Volts,NULL));
  DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"",10000.0,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,1000));

  DAQmxErrChk (DAQmxCfgAnlgEdgeStartTrig (taskHandle, "Dev1/ai0 ', DAQmx_Val_RisingSlope, 0 '"));

  For the creation of the meter, I use the following code:

  DAQmxErrChk (DAQmxCreateCIFreqChan (taskHandle1, "Dev1/ctr1", "", 1 January 2000, DAQmx_Val_Hz, DAQmx_Val_Rising, DAQmx_Val_LowFreq1Ctr, 1, 4, "");)

  I hope someone could give me a hint.

  I also tried the examples that come with DAQmx but well I know this are only examples to counter with the help of the digital inputs.

  Thanks in advance.

  Hello

  You must use the exit event of comparison at the entrance of the meter. Change this property after the configuration string function.

  DAQmxSetChanAttribute (taskHandle1, "", DAQmx_CI_Freq_Term, Dev1/AnalogComparisonEvent);

  Kind regards

• Non riesco a generare I trigger by the journal tables

  Buonasera,

  utilizzavo tables version 4.1.1 di Data model e riuscivo a generare I trigger by the newspaper, pero utilizzava sempre he nome di table "emp2."

  Nelle note della versione 4.1.2 release it era scritto che he bug era stato solved, pero adesso non riesco più a generare I trigger by the journal tables.

  You can help?

  Grazie

  Davide

  Hello Davide,.

  you are able to run the generation of 'test' as he explained here Oracle SQL Developer Data Modeler 4.1 user - defined DDL generation using transformation scripts

  Do you have a location in "preferences > Data Modeler"-"types of default system directory" - If there is a defined directory it can DM puts the script from that directory - scripts are in the file - dr_custom_scripts.xml. "»

  If you have not changed the scripts distributed with Data Modeler (or add new ones) so you can copy this file in the directory datamodeler\datamodeler\types of DM 4.1.2 installation to the directory defined in the preferences.

  In fact the problem in 4.1.1 DM was in the script itself always putting this 'EMP2' name in the definition of the trigger - line 66 should be modified in order to obtain valid results:

  old line 66:

  "WE DELETE emp2 for each line \n" +

  new line 66:

  "WE DELETE" + lname + ' for each line \n"+"

• How to hide the trigger on the top layer

  Hello

  can someone help me with this problem?

  Each icon is a trigger in the other layer.

  When I clicked on the icon, it will display the target (white box), but somehow the other icon is always on display.

  I tried to move the layer to the trigger, but it cannot be moved anywhere on the layer.

  I thought to create another separate page for each icon, but it will not reach the design I wanted.

  Can someone help me how to get the icon disappear please?

  Check the options in the widget settings. If it is enabled, clear the triggers on the top .

• Population of trigger of the field dependent on the loading of the page

  Hello

  I use JDeveloper 12 c. I have a text with a LOV entry field and the output text field which depends on the input box. I created these in the view entity such that when I change the value of the entry in the field (directly or indirectly), he correctly fills the field of dependent result. Note that the input field is linked to the data, but the result field is not (it is a transient field). So that everything works correctly.

  When I load the page fragment, the data are filled in the field as expected. But I would also field dependent for automatically filled with the appropriate value based on the value in the input field. I've tried to set 'auto-submit' on the entry field and a PPR trigger on the output field, but it was not effective. Is there a setting that can allow to do it automatically? Or do I need to use code in a backing bean? And if so, examples of code would be great.

  Thank you.

  As first, write continuation method in the Java ViewRowImpl class:

  /**
   @param lbdName - List Of Values Name you attached to the attribute
   @param attrName -LOV attribute name whose value you want to return from method
   @param arr - LOV's key attributes values
  */
  protected Object getLovAttribute(String lbdName, String attrName, Object[] arr){
      Object result = null;
      ListBindingDef lbd = getViewDef().findListBindingDef(lbdName);
      if (lbd != null) {
          Key keyForLovVO = new Key(arr);
          Row lovRow = getListBindingRSI(lbd).getRow(keyForLovVO);
          if (lovRow != null)
              result = lovRow.getAttribute(attrName);
      }
      return result;
  }
  

  Then, change getter transitional attribute, in the following way:

  public String getTransAttr() {
      if (getAttributeInternal(TRANS_ATTR) == null) {
          // check to see if databound attribute (where is LOV attached) have value, and if so, get appropriate value from LOV row
          if (getDataBoundAttribute() != null)
              return (String)getLovAttribute("_List_Of_Values_Name", "LOV_attribute_you_want", new Object[]{getDataBoundAttribute()});
      }
      return (String) getAttributeInternal(TRANS_ATTR);
  }
  

  Of course, change over the method to return the appropriate type and ajdust databound attribute accessor Get etc...

• Manager not an event trigger in the field display name of the user registration form

• Is it possible to a thumbnail of the slide show as a trigger of the composition of the layer so they both can be clicked on at the same time?

  I have a thumbnail of a slideshow in layers under a trigger of a composition. I have the opacity of the thumbnail defined at 0% so it looks nice and clean. I wish it works so that a user can click on the trigger and the tile at the same time. Is it possible through coding? Adobe told me that Muse can do by nature.

  Thank you!

  Conor

  No, it is not possible to click on two things at once. Custom javascript using you could trigger two events with a single click but with HTML/CSS, you can trigger only one.

• What is the right way to compare, synonym, trigger and the Type using DBMS_METADATA_DIFF?
