• Element memory FPGA vs point FIFO

  What is the difference between the use of a FPGA memory element () and an element of FIFO of FPGA ()?

  I am looking to unload data so quickly that possible between a host application and a target FPGA VI, but these two options seem to be sometimes used in the LabVIEW help documents and white papers.  I understand the DMA from the computer point of view works and I would use this approach because it is the fastest (I need a very fast data acquisition system).

  No one knows what what are the specific difference between these, and (especially), which will be quicker for entire U8 transfer data?

  They are both created by click with the right button on the FPGA target:

  

  

  Thanks in advance for any help!

  To transfer data from the FPGA to the host, a FIFO DMA is your only option. Blocks are only to transfer data between the loops in the FPGA. A part of memory is not shared between the host and the FPGA.

  A FIFO DMA is implemented by memory allocation on the FPGA and the facilitator. The DMA logic automatically moves data between them, but there are two distinct categories of memory, one on the host and the other on the FPGA.

  For communication between the loops on the FPGA (without involving the host), the most important difference is a FIFO, as its name suggests, first-in-first-out, while a block of memory is addressable. There are also differences in how they can be used to transfer data between the different areas of the clock loops, as described in the help. If you have a question about a specific help section, please quote or link to the part you find confusing.

• multiple choice with partial credit question, I have 10 responses only 6 are correct.  How to assign 10 points for each of the six correct answers for a total of 60 points setting?

  How can I assign partial credit so that for each possible answer 6 out of 10 each correct answer gets 10 points each, with a possible total score of 60 points quiz?

  To Captivate 7, please go to the Quizzing workspace. You will have the properties and properties Quiz Panel visible. I will now repeat the workflow, I explained briefly for CP7:

  • Check the partial score in the Quiz properties and also multiple responses.
  • Indicate the correct answers on the stage
  • Select the first correct answer on the stage text caption and indicate its score (10pts) in the properties panel, not in the Quiz properties!
  • Repeat the same for each correct answer
  • Check the total score in the properties of the Quiz Panel: should now be 60pts to the full question.

  None of the quiz system variables can be changed, they are read-only. System variables in Captivate 6 - Captivate blog explains the system variables for 6 categories, there are a few changes in 7: new features of Captivate 7.01 - Captivate blog but the Quiz category is always read-only.

• Point Set size dynamically the value of the corresponding select list

  Hi friends,
  
  Few days, before I learned a concept of change the size of the item dynamically according to the value of the selection using Jari list. I missed to ask him something (such as an extension of it).
  
  This is the thread
  
  {: identifier of the thread = 2282838}
  
  He produced the wonderful example below
  
  http://actionet.homelinux.net/htmldb/f?p=100:214:7956651650754287:NO:_
  
  Was that I missed in it, it possible to change the label of the element according to the selection list.
  
  According to the example, jari has limited the size of the element according to the selection list. Suppose that in this example if I select "China", im getting elements of different size and "India" means im get point of different size. But the labels of all the four elements are the same as
  
  attribute < li > 1
  attribute < li > 2
  attribute < li > 3
  attribute < li > 4
  
  As an extension, I need like assume that 'China' means that the label of the columns must be
  
  < Li > State
  < li > address
  < li > pincode
  < li > district
  
  If "India" is the label of the four elements must be
  
  < li > customers
  < Li > operators
  < li > units
  < li > provinces
  
  It is possible to generate different labels for the different size points, according to the value of the selection list. Since there are only four elements present in the database table.
  
  Brgds,
  Mini

  Hello

  Alter the table where you have point sizes and add the ITEM_LABEL column.
  Fill the column with the values you need for labels.
  Add the new column for the application process

  DECLARE
    l_sql VARCHAR2(32700);
  BEGIN
  
    l_sql := '
      SELECT item_name,
        item_size,
        item_label
      FROM demo_item_dyn_size
      WHERE lov_value = :P214_COUNTRY'
      ;
     APEX_UTIL.JSON_FROM_SQL(l_sql);
  
  EXCEPTION WHEN OTHERS THEN
    HTP.PRN('{"row":[]}');
  END ;
  

  And change something like JavaScript

• Point set Label above point on the form?

  My apologies if this has been listed here. I could not find with the research I've done.
  
  In my data entry form, I want to put the labels of items entrable top of the fields. I looked at the label (optionally with help) model, but it looks like that just the label itself handles. I don't see a way to get to the #BODY # of the region (region without buttons or title) do it either.
  
  Are we stuck with having always our labels in column to the left of the items in a form?
  
  I hope not and knowing a minimum necessary?
  
  Thank you
  
  Stew

  For the element, set Begin on the new line = YES and start the new field = Yes

  Then to the label set "Horizonal/Vertical Alignment" 'at the top'.

  (It's in v4.0.1.)

• Point SET value with button redirect url

  Hi guys!
  
  I wonder how to value of the element with a value of another article
  
  I use this:
  
  JavaScript:popUp2('f?p=101:2:&session.:::P2_TEST:&P100_SEL_RECORD_LIST.',400,300)
  
  but it't does not not ;/
  
  With respect,

  JavaScript:popUp2 ('f? p = 101:2:'+ $v ('pInstance') +': P2_TEST:'+ Escape ($v ('P100_SEL_RECORD_LIST')) + ', 400, 300')

  You can avoid the app_id hardcode too (if it's the same application) using

  JavaScript:popUp2 ('f? p ='+ $v ('pFlowId') +': 2:'+ $v ('pInstance') +': P2_TEST:'+ Escape ($v ('P100_SEL_RECORD_LIST')) + ', 400, 300')

• Comparison of matrix FPGA by element wierdness

  I have an application where I am comparing limits to the input values of two strain (OR-9237) inside an FPGA cards making a conditioning of signals for a subsystem in a larger machine.

  Process boundaries are sent to RT as a table and compared to a table of "raw" data entry

  Data entry-

  

  Comparison of limit-

  

  I do one per element to the "GOLDEN table" and I realize that this may or may not be more effiecient as a comparison aggregates; However, the strange thing that happens is that the sixth element of the array to limit triggers a "load error" for the fifth element of the input array.

  I send you the limit directly from the RT - PS

  

  Note that the verified calculation by reading the value defined in the FPGA. This set and get here seem to line up. That is to say, if you set the element 3 MaxLoad % or LCNominal(mV/V), it is validated on the FPGAMaxLoad output. I wonder if this has anything to do with the implicit conversion between floating-point single point-to-point fixed?

  If someone has had this experience, I would be grateful feedback on what is happening.

  I really want to engage in the DMA channel as it is a very small set of six elements that one, it seems more kill to use a DMA channel just for this operation.

  Thank you

• You try to run the scan mode and mode interface fpga at the same time is causing errors

  I'm reading a 9236 9237 and a 9215 with the scanning engine and read from two 9211 modules with the fpga. It's because I need to acquire to 200 Hz with the 9236 9237 9215 but maximum rate of the scan engine is limited by the slower module in the system, which in this case is the max of 15 hz the 9211.

  So to use both interfaces (scan engine and fpga), I followed the percisely given in this article for instructions.

  1. the project has created and added the peripheral crio using the interface of the scan engine.

  2. Add the target fpga and drag and drop the 9211 inside modules

  3. has created the fpga in interface file with and compiled with no error.

  4. interfaced with the file fpga at almost exactly the way the sample project of "getting started with 9211' by using the engine of analysis in the interface with the other modules.

  5. after the errors to discover that I created a VI that tests for just the portion 9211 code (called "thermocouple FPGA method Test.vi")

  The data returned by the interface fpga was nothing else than zeros on all channels, even if thermocouples were hooked on some of them. (all zeros as entries in the convert temperature vi gives-410, 6160 degrees F, if you happen to have the material to try this.)

  I get the following error from the open fpga vi reference:

  code error-61141
  "Thermocouple method Test.vi FPGA.
  Activities FPGA:
  
  Open FPGA interface reference.
  Reserved outside LabVIEW FPGA:  turns The RIO Scan Interface.  You must set the mode Interface FPGA chassis in order to unlock the FPGA. »
  

  It's extremely frustrating, because as I explained, I've been very attentive not only follow the instructions for concurrent fpga and analysis but also to model my VI by the example of VI, even if only for the moment, just to try to work things out.

  Any help would be appreciated as I need to fix this for the further development and I am somehow in a lack of time. I opened a support ticket (reference #7256226), but the app engineer had no time to answer.

  This should not be the case.  9211 data will not update with each sweep, but you should be able to run the scan faster than 15 Hz without problem.  Do you have specific issues with this?

  You can try making sure that the chassis is set to mode Interface FPGA and the setting is deployed.  I wrote that article that you referenced says will select the deploy option later and not explicitly speak to deploy the chassis later.  Run a VI with a reference open FPGA vi not automatically deploy chassis settings if you need to do it explicitly.  Try the following steps.

  1. right click on the frame element and select Properties.  Make sure that the Interface FPGA option button is selected. \

  2. right click on the frame element and select deploy.

  3. repeat your VI.

  The data returned by the interface fpga was nothing else than zeros on all channels, even if thermocouples were hooked on some of them. (all zeros as entries in the convert temperature vi gives-410, 6160 degrees F, if you happen to have the material to try this.)

  The likely cause of this error is that the setting of the FPGA Interface on the chassis has not been deployed.  If the chassis is still Mode Scan fixed personality bitfile will be loaded on startup and the FPGA will be locked.

  It's extremely frustrating, because as I explained, I've been very attentive not only follow the instructions for concurrent fpga and analysis but also to model my VI by the example of VI, even if only for the moment, just to try to work things out.

  I'm sorry that you have had difficulties.  Assuming that I'm wrong about the source of your problem, it seems we have to update less than Ko to include the deployment step.

• Several loops of RT; A single FPGA reference

  I have three loops using the same reference FPGA.

  Loop 1 - reads most of the data in the FPGA for display on the HMI

  Loop 2 - using the information made available to the loop 1 as well as some additional data that is read from the FPGA to perform the functions required by the HMI controls and writes for the FPGA.

  Loop 3 - uses data from Loop1 as well as additional data read the FPGA to run commands fuctions and wrote security for the FPGA.

  My questions are:

  The FPGA Refence points to a single memory block where all three loops are looking at the same data?

  I need on While loops shift registers to keep data updated correctly?

  I need to run the three sons reference FPGA close While loops to close the reference correctly?

  Yes.  N ° N °

  I assume you mean wire reference FPGA entering a node that reads the FPGA reference you speak or write in the Panel control or indicator that is part of the VI running on FPGA.

• FPGA - try to use the screw of the replication of RIO to replace going to reset the FPGA running

  Running LabVIEW 12.1

  We have an application that uses an FPGA that was compiled in Run to Reset (works on any reset or power on).  Sometimes we need to update the image on the RT and FPGA and I downloaded the NI RIO replication screw.

  The problem I have now is that when I got to download the bitfile on the Flash FPGA on the sbRIO9636, I get the following error:

  Error-61141

  Possible reasons:

  LabVIEW FPGA: The operation could not be performed because the FPGA is busy. Stop all activity on the FPGA before asking this operation. If the target is in the Interface of Scan program mode, put in FPGA Interface programming mode.

  My updater is stand alone EXE.  He isn't able to get a link to the FPGA, because we are not sure what Bitfile currently is on a particular system.  I tried using the open FPGA reference and load a VACUUM on the FPGA bitfile by setting the FPGA to RUN when he sound the FPGA VI of the Open reference - and it works for me to erase the bitfile.  It does not allow me to immediately after run the bitfile VI of replication of RIO download - even if I close and reset the FPGA before trying to download the Bitfile for the RIO Flash.

  I have to first delete the existing bitfile, then load a new?

  Well, I found what I consider as a workaround - but maybe it's required to do things - but it doesn't seem like it should be, since the RIO device Setup.exe is able to flash or clear the bitfile regardless of the State of the FPGA.

  What I've done is to define the FPGA to "do not load automatically on re" then call the RT Config screw system and order a restart of the system.  The RT operating system restarts and then restarts the RIO system and this ensures that the FPGA is not busy.  Then I'm able to erase them or write about a new bitfile for the RIO Flash and set the "Automatic loading on any Reset" Rio de JANEIRO and restart the system again.

  Our current situation, it will work.  Long time restarts do a bit of headache.

• GetCommand does not return my configuration of entry points?

  If I'm in a file of sequence of customer and I want to run dynamically my own configuration entry point in the process model which is the best way to do this?

  I try to get the application manager through a step of the activex using Engine.GetInternalOption (InternalOption_ApplicationmManager), and then I choose the GetCommand with CommandKind_ConfigurationEntryPoints_Set method.  It will use only a clue to one of the entry points setting 3 by default (report, model Options, or Options of database Options).  If I try to make my own, it throws an index out of range.  It's position to James Grey here: http://forums.ni.com/t5/NI-TestStand/Calling-a-Configuration-Entry-Point-from-a-C-code-module/td-p/1... (I'm not in .NET well.  I just want to use activex steps in TS).  The default 3 those who work perfectly.  It's only when I try my own that I added.

  Any thoughts?

  When you run again you do execution of process template or a direct call to the sequence? If you make an execution of process model with a sequence of the client file and the specified model, it must call reminders. I don't know why the case of app Manager you try does not work. Maybe someone else can help with that. I wanted to just suggest the new approach of the execution because it looks simpler.

• synchronization sequence FPGA structure problem

  Hello

  I use a sequence structure in a VI on the FPGA to a cRIO-9073. The time of each sequence is active is determined the number of times defined by the user. In theory, each sequence should take the same amount of time, but when I check it with an oscilloscope is not the case. The signals produced do not have the same cycle. When the number of ticks is equal to 1 in the VI on the FPGA, I receive a frequency of 400 Hz, approximately to the blockwaves outputs. I expect it is much higher since the FPGA runs at a frequency of 40 MHz clock. Why the frequency of the signals so low and why isn't the market factor the same for all signals?

  Best regards

  Beurms Jasper

  Several of your synchronization on the FPGA screws are set in milliseconds, not ticks; in all cases but cases #2. I hope that this is the problem. Double-click the VI and change the setting. In fact, why have a timer to wait in any case? Just pull it outside the structure of the case and have 1 instance of the VI in the while loop. Also, whenever I see the files named * _ it probably means that you do not use the source code control. I would highly recommend.

• Error-50001 FPGA

  Hello.  My name is Jason. I'm working on what should be a very simple project to form a collaborator on the material OR that we work.

  I used this equipment in the past to remotely control a ranger xp.  I tried to use the exact configuration of the code... I'm not sure what I did wrong.

  Screenshots of the Project Explorer, and the screw runs on the PC, the cRIO FPGA have all set up and.

  The goal

  I want to be able to Flash an LED using the crio and control the speed of the flashing of a VI running on my PC.  The VI running on the PC has a slide to control the speed of blinking and a Boolean switch to activate and deactivate.  The VI on the cRIO multiply the speed by two and shows the State of the Boolean switch.  These values are passed to the FPGA VI which is supposed to turn off the led market and stop.

  The problem

  The PC code and cRIO seem to do exactly what I want to do.  Digital i/o does not value. There is no error coming out blocks of reference or FPGA read/write.

  I didn't know where to post this because I can't see the error is coming from. The only error I have found is when I right click on the program, I wrote and respected to run on the fpga and try to download it.  This error - 50001 and causes "an attribute whether explicit or implied is not relevant or is not relevant given the current state of the system. The operation could not be performed as indicated. »

  Hi jcoates,

  Please take a look at this knowledge base article: Why do I get error 50003 when you run an FPGA VI on my real-time controller?

  If this does not resolve the problem, you are able to get a simple FPGA VI, which does not interact with the LED work?

• How to control the speed of the pointer mouse on the login screen?

  How can I control the speed of the pointer mouse on the login screen?

  I put the speed of the pointer in a way at once two users accounts.

  I think that when I go to the login screen by using change user, the speed of the mouse pointer is the same as the user configured the pointer speed.  (I suspect it's the speed of the pointer to the user account that I'm spending.)  TO BE DETERMINED.  "But it doesn't matter, because they are the same).

  However, when I go to login screen using Log Off, the mouse whips autour at a very fast speed - much faster that the speed of the pointer set up users.

  [EDIT] It is also the speed of the mouse when you go to the login screen after you start the computer.

  It is disconcerting to the 87-year-old who uses the computer.  (Read: barely in computer science.)

  FYI, I don't have not noticed this until I went from a wired mouse to Dell for a Logitech wireless mouse.  (I have turned to bike computer.)

  Also, users configured users pointer speed is the 2nd from left to right, with improved set the pointer precision.

  I wrote:

  By examining the registry, I found that MouseSensitivity is set to 2 for two HKEY * users, but it has been set at 10 for the other four.

  The problem was solved by putting others 01:56 institutions.

  I have this will mark as answer unless someone offers a better solution soon, ideally one that doesn't require editing the registry.
