• Fortunately the cRIO merger two time real screws: analog and digital output

  Howdy,

  I need help with a cRIO code.  The purpose of the code is to acquire an analog input from the NI 9234 c series module and be able to send a "signal of pulse" digital camera (first low for some time, t1, then high for some time, t2) from a NI9401.  Separately, I wrote the code to perform both tasks.  However, when I add the code of RT digital output pulse pulses to analog input RT code, the DMA FIFO overflows because of the way that my digital pulse output code works.  Currently, there are two reasons which overflows of the FIFO:

  1. The digital output code is pending for a while loop (pending "Send Pulse" become a true), the loop I can't empty the buffer FIFO
  2. The FIFO is not enough, quickly emptied depending on how long the pulse (t1 and t2) times are.  The way I keep the pin high or low for a defined period of time is by issuing a sleep command, which blocks the loop I empty the FIFO.  (Is there a "best" way to sleep?)

  I have attached photos of my codes FPGA and RT.  Please give me a suggestion on how to marry my two loops of RT for the use of happy resources!  Thank you.

  I found a quick way to solve this problem.  I moved the timing of the Digital pulse on the FPGA.  So whenever I have a Boolean value, the FPGA generates a waveform with the settings I put (a pulse in my case).  This works because the FPGA loops run in parallel, I think.  That's why, when I run a pending order in the loop of FPGA digital output, it does not prevent the FPGA of analog input loop to run.  I have attached a picture of the code.

• Get information about the physical location (serial) Visa (slot) in PXI time real (Pharlab)

  Hello

  I PXI system with controller time real (OS Pharlab) and many maps series (about 6 cards).

  The maps in the series are two different models, which each contain several (8431/8 and 8421/8) serial ports.

  And the COM Port enumeration mix and I would like to know the link between COM numbering where it is linked.

  I have already dealt with a few methods:

  1. I've tried using the node property of Visa but he cannot know which card port COM belong

  2. I tried to use the Configuration Library system and don't manage to get general information of the card and not what ports have this card.

  3 try to fill you with the VisaConf.ini, but discovers that ASRL and COM Auto-enumeration is the same.

  4. I tried to look in NISerial.ini, NISerial.dbs and NOR - RT.ini and did not find any help here.

  Application engineer or support suggest to look in the registry of the operating system Pharlab because it is windows based and material information must be stored in the registry

  Further explanation on the problem of PXI enumeration:

  PXI produce enumeration auto for the ports series (COM3, COM4, COM5...) according to the card slot, but when there is a mix of the two models of the system would then list a model (8431) from 3 to 50 (6 cards and 8 ports) and the other model (8421) 51 to 98. so if I have 8421 in 2 and 8431 slot number in the slot number 3 it would list 2nd slot COM59 to COM68 and 3rd slot COM11 to COM19.

  Why not just use NOR-MAX to manually configure the ports?

  The system is essential and can not be stopped for a long time and he operated by people who are not very technical, so the customer who wishes to be able to exchange business cards without futher configuration.

• Time real ADC/DAC for SMPS by using Labview and USB

  Hi all

  I asked the Sales Department of this same question, so here's a two-pronged approach:

  I am reserching a control algorithm for power switching, and so far, its performance simulations seem to be good.  Now, the goal is to implement the circuit from the experimental data.

  I've seen several NI USB DAQ boxes that seem to have the performance, I'm looking for (for example, the box USB-6211 a sampling rate and resolution I need).

  The control algorithm uses the following mathematical functions: add/sub/mult/div/exhibitor and derivative/integral.

  My question is this: is "strong enough" Labview take four-channel data 250Ksps, crunches the numbers in an equation and spits out the answer to an analogue on the channel, while time REAL?  I'm looking for a rate of analog output of ~ 100 kHz.

  Thank you for any suggestions you have!

  -Rick

  Hey,.

  So if you were trying just to perform an input or output, then the box USB-6211 would certainly be able to treat it as the machine clock could manage the inputs/outputs, no software. However, what you are wanting to do, basically a feedback system, he will have to avoid (at least to a USB device) because you need to be able to specify Active which is the output. So, for this reason alone and the fact that you want out of 100 kHz, this device and the USB devices in general will be not an option any what software you use, LabVIEW or otherwise. On another note, you want to make sounds more like live update, not in real time, which is more on the jitter. Bottom line, for these kinds of requirements, you might need to move to an FPGA card, something like the NI PCIe-7841R would work. It's more expensive, but for your needs, FPGA will be the only option and it comes down to the latency of the bus, but also the response time of software. With FPGA, as shown in the first scheme of the following document, you basically close your software through hardware loop.

• Real-time target - change IP and shared network varables

  Hello

  I create an application for the system in time real (Compact RIO).

  All data between the (current running on a windows PC-based) GUI and the real time system - is transferred via shared network variables.

  Shared variables are hosted on the target.

  I attributed the static IP address to the real-time target.

  Now for the question:

  After the deployment of the application in real time on the Rio target compact

  If I change the IP address of the target: how the shared variables 'know' to connect to the target?

  There is no place in the GUI (running on windows PC based) I set the IP address of the target.

  So I change the IP Address of the target (and for the sake of argument if I change the IP address of the PC, but they are always on the same subnet) - how to 'know' how to connect?

  Looks like a basic question I am absolutely certain I'm missing something to understand shared variable...

  Thnaks

  Hello Hazkel,

  The IP address of your shared time variable real target is located in the *.aliases file when you create an executable file, you will need to change there.  See the example below:

  

• Create a subfolder of bookmark in time real bookmarking a page in a folder that I created for a registered earlier does not work

  Create a subfolder of bookmark in time real bookmarking a page in a folder of bookmarks, I created a saved bookmark previously does not work.

  Previously on a Windows XP computer, I could choose the "select" option and create a new folder under the folder I chose to put my new bookmark. "." On this computer, the 'new folder' option is not clickable.

  I thought about it. Thanks anyway.

• using the module time real Labview in RTAI

  Hi all

  I want to use the module time Labview in RTAI real for real time due to its open source applications and very good performance. is it possible to make this work?

  If this is the case, can anyone introduce a single study of case or something similar to this?

  I don't think it's possible for anyone outside of OR. LabVIEW Real-time supports this time only Windows as host and as a target only material of National Instruments with specifically targeted OSes or the Pharlap ETS system on x 86 systems with hardware specific enough. Using RTAI as target OS for LabVIEW Real-time applications requires first a few changes on the time plugin real LabVIEW to support this new platform.

  None of the files in time real LabVIEW also created for either platforms OR running VxWorks or OS Pharlap, Pharlap ETS system woud be able to be deployed to a system RTAI, because they are not compatible. In the first place, you'd have to port the bunch of shared libraries that make up the time target real system running LabVIEW on one of these goals to your RTAI system which is in fact a whole new platform of LabVIEW you can create with a little effort from the LabVIEW source code. It's not really impossible for OR as most of the code LabVIEW is written platform completely independently, but it would be a combination of the parameters compilation for course LabVIEW Real-time, with the settings to produce time targets real LabVIEW VxWorks with some additional settings of Linux. Yet, it would be by far not trivial and some parts are actually hardware specific drivers that must be worn too and limit the possibilities of what RTAI material could serve even further. In short not something that would make any commercial sense NC because they invest a lot of resources with no opportunity to sell additional hardware.

  And hell freezes over up front release of NI LabVIEW source code in any form which gives access not - OR used to it!

• Lack of time real plug-in

  I have a project in real time using a 9074 cRIO chassis. The project opens fine on my desktop but when I try to open it on my laptop, a yellow triangle with an exclamation mark inside appears at the level of the chassis and don't see anything below the level of the chassis. If I right click on it, it just says: "the plug-in for the selected item is not installed on your system or the plug-in has a license has expired. I have installed all these elements on this machine:

  NIRIO1310f1

  LV 2013 SP1

  SP1 FPGA development

  SP1 of development in real time

  NIDAQ1400f1

  Don't know what else I could possibly be missing, don't remember installing something more on my desk? No matter what project I try to open, any project won't let me in time real access below the chassis level. If anyone knows what I could miss I would appreciate the help. Or if you need more information.

  Thank you.

  I installed NIRIO14f1 and my phone seems to work again.

• Average displacement Subvi does not refresh the data in time real host VI

  Hello!

  I time real host VI that has evaluate the NI 9215 cRIO block data 9073. He takes analog data and calculates the phase shift. It works well with the connected equipment and displays the results. I need to get the moving average value of phase shift, so I add moving average Subvi, where main VI entries - new value (phase shift measured) and ms and output - average value of travel time. When I run real time host VI it gives me a single data and stop get new data from Subvi. It refreshes not even values measured in real time. So the problem somewhere in the accommodation, with sub - VI. How it can be solved? How can I get real host VI with the moving average value of Subvi update running time?

  Thank you.

  Your problem is that you have a loop that runs until you press the Stop button inside your Subvi.  If you try to use a Global Variable that is functional, you have a few things wrong.

  1. the loop should run only once.  A TRUE to the conditional stay Terminal wire.

  2. the shift register cannot be initialized.  That is how he can keep the old elements in a story.  Use a first call? with a case structure so that you only initialize the table of history inside the loop on the first time the VI is called.

  But if you really want to make your life easier, just use the PtByPt.vi mean.  NOR did all the work for you.

• In time real CRIO - writing a file on a PC hard drive

  Hi all

  I am developing and application with the following hardware features:

  Time real cRIO 9004 target device

  HAVE cRIO 9205

  AO cRIO-9263

  and the following programming features:

  I run an FPGA VI to establish PID control where the reference signal generated in the FPGA and the real is an acquired signal through the cRIO 9205.  I also find target FPGA FIFOs host in order to pass the data from the FPGA to the application of the RT.  The time real VI will run in the 9004 cRIO processor.  Now, with the data from the FIFO I would write a file (regardless of the extension), in order to do more tests.  I did it but I don't want to use the local memory of the RT, instead, there will be a PC (hard drive) where I can place the file in order to write it (with data).  I'm not able to do so, as 1) I don't know how to call the PC hard drive and 2) I don't know what communication protocol fits better I want to develop a device to Windows Welcome.

  Nobody helps me?

  Thank you very much

  Enrique

  The cRIO-9004 unfortunately has USB, so you can not write on a USB Flash drive (which would be my first suggestion).  If you want to store the data on the host PC, you will need to write a simple TCP/IP client/server to send data to the host through TCP so that the host can receive and save to disk.  Façade of the VI may seem as it is running on the PC, but it's actually just show you data be listened to the target (you are not allowed to piggy-back on this same Creek).

  There are several examples of TCP/IP client/server integrated into LabVIEW.

• Execution of several executables in time real (.rtexe)...

  For PXI (or any embedded controller OR) several executables in time real developed in LabVIEW (.rtexe files) can work simultaneously?

  I'm almost certain that the answer is 'No', because the whole point of a RTOS is the code to be "as deterministic as possible", with the Jig and schedule reduced by removing items (such as "interference of the BONE") out of control or understanding of the developer.

  Pouvez, however, write a single RT executable that loads into two routines that work "in parallel".  If you have a multi core processor, you could book separate processors for two routines that should improve their independence from each other.

  We met a slightly different variant of this issue during the migration of code LabVIEW 7 to a LabVIEW Project "oriented" development (introduced in LabVIEW 8.x).  We used to have several different programs of LabVIEW RT who has used a code different on the PXI - when we ran the host executable, it loaded and run the appropriate code of RT (recorded in a .llb).  This works well with executable RT.

  What we developed was a system where we have recorded each RT executable as a routine named separately ( not Startup.rtexe) and set them (initially) to run as a startup.  When the host code runs, it queries the PXI for the name of the startup routine, and if it is not 'just', change us it on the PXI and make the PXI to restart.

  [In fact, don't really do us this way, that 99% of the time, we always run the same executable RT.  What we did do was to write a separate "define RT Startup" routine that we almost never executed, unless we "know" we run an earlier version or something like that.  This, in turn, tells us that the PXI is configured to run and what executable RT can be defined as startup, then makes the changes, restarts the PXI and exit.  The 'rule' is that if you change the executable RT, don't forget to change the back when you're done.]

  best,

  In it's current state given after effects is mostly from the CPU then graphics cards make little difference in performance. Adobe usually (but there is no guarantee) announcement of updates at NAB tends in a few weeks, so I would hold off buying new hardware, including expensive equipment, until you see the new requirements and dates for new versions of output.

• Is it possible to get a panel of Photoshop to receive updates in time real color?

  Hello community CS SDK!

  I hope that I can tap into your knowledge of experts here because I'm not an expert (yet intellectually curious and always want to learn). I was able to build a few panels and write some scripts useful for Photoshop with success. But so far, I would not say that I did something too ambitious. Now, I'm ready take the next step.

  I am currently developing a Photoshop Panel that did some calculations and analysis between the foreground and background colors. But I need to find a way for my Panel to receive real-time updates of foreground and background colors, but I honestly don't know how or where start. Specifically, I would like as my Panel to receive this kind of events, so that I can update the value of the color associated from Photoshop:

  1. Foreground and background color change events to stay in harmony with the colors of foreground and background in Photoshop:
     
     
  2. Events associated with Photoshop color dialogue selector and how the Panel can get the 'new color' value (before the user clicks OK):
     
     
  3. The color that is under the mouse cursor (color in real time as can be seen in the DETAILS pane data):
     

  I thank you in advance for any help, you might be able to provide!

  What you have looks like a valid syntax.

  My guess is that by copying the code of the documentation, you copied the french quotation marks (http://en.wikipedia.org/wiki/Quotation_mark_glyphs) and the compiler will not like that. I manually replace all quotes and retype it to make sure they are all dumb quote.

• every time I erase content and settings on my iphone 6 after reset at the start of my phone and after crossing the screen as Hello > select language > Connect wifi > my iphone doesnot ask me activation lock even if my unit is also found on

  every time I erase content and settings on my iphone 6 after reset at the start of my phone and after crossing the screen as Hello > select language > wifi connection > my iphone doesnot ask me lock activation that says that your iphone is connected with the old apple ID, please enter the id and password

  I always reset on find my optional equipment please tell me how to activate locking activation so that whenever I have factory reset my phone with finding my camera so my phone always ask an old apple and password

  I do not understand your question, but let me go with what I believe. Looks like you entered in iCloud and erased all the content and settings on the iPhone, and once you go by assigning back up again, you do not see something that you expect to see, for example, a request for an Apple ID. When you go through the installation process to select the language, etc., it must, at some point, ask you to identify yourself with your Apple ID. are you not see this?

  It would be better if you try to describe exactly what you do again. Also, without the help of any sign of punctuation, it is difficult to track everything you ask. Try providing the steps of what you do, and then what you see when you get to the point that you believe that something is going wrong. You mention both an old and new Apple ID, which is rather confusing.
