• queues the IMAQ image data type

  I'm trying to run multiple queues in the same loop entering IMAQdx images from several cameras, and then save to AVI. After reading the site nor a little, I discovered that the reason why I get only the last image of each bucket, repeated on all frames in the AVI file, is that the IMAQ image data type stores only the memory location for the image, not the image itself data. However, I don't see a better solution for the queues of the actual image data. What conversion could be the fastest / are in charge of the processor the lowest?

  

  For each image you must initial Image space.

  You can use something like this:

  

  You need to add initialization camera (s) and AVI. You must add the multicamera feature. Stop recording is missing.

• Using film as a data type time codes?

  I work in the film, and I was hoping to use numbers to help me create quotes for a VFX project (based on cost per second). I tried to create a custom data type, and it works almost out of an important obstacle. -That, even if he is HOURS: MINUTES: seconds, DURING which it is not no matter what equivalent of FRAMES (which are usually 24, 25 or 30 depending on what video format you are working in).

  I use Adobe Premiere to export a list of lots of files under a CSV file, which are fine numbers. However, manipulate these data is - I would say - impossible without the support of the video time code. Anyone working on a solution for this? Or is there a suggestion feature to me link to forward this to the team of numbers?

  Thank you very much

  You can give your comments and suggestions to the numbers > provide comments numbers in your menu.

  But everything first, perhaps you could post more details of your problem, what your imported data looks like and what result you want.

  If the imported data includes a column for the frames I think you can convert that.  In all cases, the specifics would help.

• Work with the first HP data types?

  I'm trying to get a clear understanding of the data types of HP Premium so that I can better exploit feature internal rather than copy and paste, edit, or having to retype. However, I can't find a tutorial, guide to style "quick start" or comprehensive information on this subject anywhere. Finally, I would like to do things like the following:

  (NOTE: I only list these questions in order to better explain what I'm looking for.) "There ARE no need to answer.)

  • Pass a list of expressions (sometimes solve() returns a list) in a function such as unapply() and run it on each item, rather than interpret the list as parameters
  • Precede the value of formula 1, "Y =" and then save the result in V1
  • Understanding type (x), type (X) and ('X') - I understand that X is a floating point number; x and 'X' they return all two DOM_IDENT, but are in that they also treated the calls function?  Or 'X' becomes X and then treated as a float value?
  • Is there a better way than unapply(), to replace by X-> x to a function, a function of return?
  • For example if: F1 = X-> Sin (x)
  • NOT a function: the seizure of F1 (x) returns the expression: Sin (x)
  • IS a function: unapply entry (F1 (x), x) returns the function: x-> Sin (x)

  Is anyone know if such a guide or tutorial exist, and if so, could you please point me to it?

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.

• Custom data type

  We use a custom data type container and add variables to use in the sequence inhabitants.

  It seems that the field of the local variable names having to match domain names that they have seized originally in the custom data type container.

  We want to reuse the custom several times in the sequence container for data type and would like to have descriptive field names of their use, which changes throughout the sequence.

  Is it possible to just rename the names of the fields of a local variable is of the type, data type container custom, while maintaining the field names the original custom data type container?

  With the help of TestStand 2013

  Thank you

  Hi CC57,

  I also recommend trying a templateVariable. You can use this to create a container with a particular name that you can copy in various places in the variable pane and change the names of the properties of confined there.

  Thank you very much for your help!

  Buddhist salvation,

  It seems to me that you would be better to use "Linear Mapping" in the palette of ANALYSIS "Suitable curve", but you should be able to get your code works by passing the name of the channel in this second parameter instead of an empty string variable.  You would have noticed that if you had OPTION EXPLICIT the first line of your code - always a good idea.

• Added properties (Group and channel) are not a numeric data type.

  I use a use to add two groups and channel custom properties. The properties are text and digital, double and whole.

  When I create a request in the browser, I selects the custom using the drop-down list property, but has only the drop operator "=" or "<>". "" The property is displayed in the data portal is a number of float. I had this problem when I was adding properties custom by using a script. I then tried "Navigatorinstallation / my Index DataFinder/Reset/Reset", then repopulated my search box, using the use on my raw data files. At this point, all the properties of my have only the "=" or "<>" choice of operator in the query.

  It seems that my properties are digital in the data portal, but the the query string of the browser.

  Thanks in advance,

  Hi Bill,

  You don't have to delete the files.  Choose the NAVIGATOR menu "settings > My DataFinder > reset... '. "can clilck on the UPPER part of the two buttons, one called"reset the index.  Which will remove all records in database and re-index all of your data files.  If you one of these properties have already optimized, set their State not optimized before resetting the index, otherwise the optimized property data types will persist.

  If this does not help, then the problem could be in the use that you use.

• Get the Data Type of queue

  I'm working my way through my first vi producer consumer and I have two questions.

  1 I am the queue data x, y samples acceleration waveform type z. The code snippet shows how to set the data type in the queue to get. It is rather ugly and disturbing, even if it seems to work.  Is there a way more elegant and beautiful to set the data type?

  2. the sampling frequency of the accelerometer is 5120 Hz.  The DAQmx Read buffer is 1024 length samples.  Therefore, it takes 200 [ms] to fill the buffer.  I put the metronome 100 [MS] to ensure that the producer is not without samples.  This means that the loop While producer will spend much of its time waiting.  Right?  Given the wait cost anything?

  In ProducerConsumerExample.vi of LabVIEW, the sampling frequency is 10000.  The size of the read buffer is 1000.  And the metronome is set to 100 [ms].  The sampling frequency of the device comes from the hardware device in the cDAQ.  100 [ms] interval comes from the PC.  It will not be a mismatch?  I would like to understand this before I put my metronome to 200 [ms].

  Then, can shed you some light on the behavior of the loop while you mentioned is not a metronome that is is punctuated by DAQmx? I think it would do a lot of rotation.

  It is not spinning as he waits inside the DAQmx Read for samples N must be obtained.  This isn't a request for data.  It takes time to collect these samples.  That length of time depends on your sampling rate and how many samples you request.  So because he is waiting inside the DAQmx Read, there is no need to add an additional wait.  Let the DAQmx Read limit the rate of the loop.

  It's actually like the loop of consumer for the consumer to the producer.  Playback of the queue will limit the rate at which that loop runs.  It should therefore no waiting.

• DLL custom data type

  I try to use a DLL in LabView that talks about an acquisition card. One of the functions requires a custom data type (MID2250_MDConfig_t) that LabView does not support by default. It is defined in the C header file as follows:

  typedef struct
  {
  int CoordsX;
  int CoordsY;
  } MID2250_PointCorrds_t;

  typedef struct
  {
  MID2250_PointCorrds_t ULPoint [4];
  MID2250_PointCorrds_t BRPoint [4];
  unsigned short u32SADThresholdValues [4];
  unsigned short u32MVThresholdValues [4];
  unsigned short u32SensitivityValues [4];
  } MID2250_MDConfig_t;

  Is there a way I can integrate this data type in LabView correctly. I saw people talking about wrapper dll on this forum but I'm a bit confused as to who. Can I create a similar cluster in LabView and pass it to the function using "node of the library call?

  Since the tables are all fixed size (and not huge), they really are inline in the structure. This means that you can simulate a cluster containing many elements inside because it is the elements of the array. The first Point of the UL would be a cluster containing 4 cluster with each two int32 in it. Ditto for the second element. The third is a cluster with 4 uInt32 and so on.

  Then configure the setting to adjust the type and thread this cluster, and voila.

• Problem of XML data type

  I am trying to unflatten data from an xml file but my entry type for the type on the unflatten my guess isn't valid, and I get error 1106.

  Is attached, the file xml and VI

  XML file is in text loading constraints

  Your cluster of data type does not match your XML file. Fixed VI (LV version 2013) is attached. However, the file you posted seems to be a single element, not the entire file, so I can't verify that it works.

  If you have a previous version of LabVIEW, the cluster lacked a time stamp and had a cluster at the end which should be a string.

  Double post here.
