• SoftMotion cRIO - how to read the position of a host from a sample of the expedition?

  When you open the examples provided with NI SoftMotion, generally there are two loops. The main loop and a loop that contains the following message:

  "The position of reading and tracing normally would be on the host by reading data from the target.  This is done in this example for simplicity. »

  Then, we advise on the Panel before you go to ni.com/info/f/ and enter the info code nismex for more information on the use of this example in a system of real movement.

  My question may seem obvious, but how "read the position on the host by reading data from the target?

  I tried to use the block function NOR SoftMotion read inside a VI on the host, of course, it does not, because the resource is on target.

  Should I leave the second loop inside the VI running system cRIO and just no conspiracy, but subscribe to a shared variable? I see that you can do a right click on the function block and select if you want output to be a shared variable. Or this second loop is supposed to be removed from the VI running on the target RT? How reads the position then?

  To see an example of what I mean, open this example: C:\Program NIUninstaller Instruments\LabVIEW 2009\examples\Motion\FunctionBlocks\Axis Straight Line Move\Axis right Line.lvproj

  Concerning priority and when you call the motion function blocks:

  The NI SoftMotion engine for cRIO uses a background 'pilot' that runs in phase of analysis on the CompactRIO system engine.  This provides the required sync and sync for motion runs correctly.  This 'pilot' motion function blocks, simply send asynchronous commands.  You can consider them as an API to the engine of control of movement control.  You are not required to synchronize the function of movement of the scanning engine blocks or even to perform at a highest priority.  However, you will probably choose to run these a higher priority or in a loop timed for reasons of prioritization of execution.  For more details on the NI SoftMotion architecture and recommendations on how to build movement on CompactRIO systems discover the CompactRIO (http://www.ni.com/compactriodevguide/) Developer Guide.  It has been updated in December 2009 and Chapter 5 now has much on the order of movement on CompactRIO complete with examples of projects.

• How to draw a straight line and write on areas colored with Photoshop?

  I need to be able to draw a straight line and write about areas that I colored. I could do in PhotoStudio, but I don't know how to do in Photoshop.

  Use layers.  Text for writing on areas layers.  They can be changed.  You can change the text, font, size, color, Position, fusion and opacity and a layer style can be added.

  To draw the limes add a blank layer.  Select a brush and the color.  Left-click on one end of the line you want to draw. So without and the button to move the cursor to the other end of the line and press SHIFT + left.  Photoshop will draw the straight line between the two points that you clicked on.

  

• VISA, read and write checks are block after there is no more lines to read

  Hi all

  I am developing a communication continuum between a microcontroller Arduino Uno and LabView. The issue I'm having is to 'Write' and even 'Stop' controls are block once all the initial reading lines are read in. I'm pretty sure that this is because the reading line prevents the complete completetion of the while loop, suspending all the loop until it indicates something else. I tried a number of Boolean operations and I can't work around the problem. The code itself needs a way to detect has nothing to read and ignore the read statement and continue a loop until the user activates the "write" command and writes something. The read command would have would be to read and wait again for user input.

  Any suggestions and help would be great! Thank you!

  * Note that I was using labview for all of 2 weeks. I'm getting used to it but I'm not a pro for sure.

  Also, I would like to give credit to physicslight @ https://physicslight.wordpress.com/2014/07/14/arduino-labview-serial-write-read/ for provide an arduino auto detect sub vi for easy then to initialize the VISA controls

  Seems I solved my problem. Using the Instr:Bytes function of the Port, the reading error is fixed. Addition of a few cases to see entry written and that it is received and a delay just incase seems to have fixed my code! If anyone has a similar question see my attached code

• Director of Windows: I have a song that lasts 3 minutes and when I imported into windows movie maker, it appeared that a straight line and said that the song is only 1 second! I need help!

  My song appears like 1 seconds for a long time even if it is actually 3 minutes long and it plays very well. When I place it in the Audio section / music he appears just as a straight line...

• When you use the "Fill & sign PDF" feature, is there a way to stretch to resize the text box, to an area of the page... rather than through a long straight line...?

  When you use the "Fill & sign PDF" feature, is there a way to stretch to resize the text box on a specific area of the page... instead of the text box is in a long straight line...? I do not see there is an option or the ability to do so, just want to confirm.

  Improving the management of multiple line text fields is in our plans, but for now, you need to add manual carriage return (Enter).

• Absolute error-70216 SoftMotion starting linear movement

  When I start an asynchronous linear movement to aid softmotion express straight absolute move, the VI throws sometimes mistake-70216 (within 24 hours, this will happen certainly but not very often) and won't start not when I activate the performance indicator (no doubt goes from false to true).  Therefore, I am still able to run other commands (for example, can make a Straight Line speed and a reference to move) but not absolute moving Straight Line.  I don't know how to recover if I take this error, the only way I found to get it back is to restart my application.

  I'm running on LabVIEW Softmotion 2015 2015, the VI runs on a three 9035 and driving 9505 modules using unrelated areas.

  Hi Omar,.

  It seems that this is the intended functionality.

• A better way to make a continuous read/write on a NOR-6008

  Hello

  I use a USB of NOR-6008 module and have a loop of the software configuration where I acquire analog signals, digital signals, then, then put a digital high or low and repeat. I use digital multiplex outside the material so that I can use 6 of the analog inputs to read 12 signals. The digital inputs that I have are connected to the buttons on a panel that are used for the entry instead of the screen of the computer of the user. My loop is also to build a buffer zone of all the signals on the analog and digital lines that I read in so I can on average and this process elsewhere in the program.

  The question that I am running is because this loop is very slow and on the final product is performed on a touch screen, XP Embedded PC and just this acquisition loop begins again as much CPU as the rest of my program. I would say that drops of loops on 4 or 5 cycles per second, which means that my update of 2 multiplex signals or longer than a second time. I would really like to better performance and does not use as much of my CPU resources.

  I use a way simple enough to make the loop of the acquisition, by setting the parameters I, reading, deleting the task, defining the parameters DI, read, erase the task and then by setting the parameters, write about it and delete the task, which gives a slight delay and repeat.

  Any thoughts on a better way to start the read/write that what I'm doing?

  I have attached the code examples in the loop of the acquisition that I use.

  Thank you!

  First of all, the best plan is to move the chain DAQmx before the loop to create and use a start DAQmx, then write in the loop, then clear once the loop ends.  This configuration must be done once, not every time you write the channel.  This should speed things up considerably.

• Acrobat DC light - how to highlight in a straight line...?

  Hi all -

  Our office has recently installed Acrobat DC and we are more familiar with it, as we will...

  For me, I get large scanned document files that I read, put highlight, redact, sometimes edit and comment.

  I am able to use the tool matches pretty easily, but is there a way to highlight a straight line, rather than having the jolt of a brand of hand my gaze of non-professional document?  The highlighter gives me a circle for a slider and he do not embrace the line of text at all.

  Any help is appreciated.

  Thank you

  Frank

  The highlighter tool only works on the text even, it is not a free-form tool. If it allows you to select no text or only moves when you move the mouse, then it is not nail tool you use, but something else.

• Help? the source volume is read-write and can not be disassembled...

  I use 10.11.5 on an iMac 21.5 ", end of 2009 and I want to restore the OS X 10.11.5 to HD on an external drive but I get this message" Source volume is read = write and cannot be disassembled, so it cannot be copied from block. "  I can find answers do not address El Capitan.  Help would be greatly appreciated.

  .. .Goldie

  You use disk utility's restore feature?

  If the HD has a recovery partition, you can make starting in place of the recovery.

  Or you can use SuperDuper! (the basic version is free and can copy the entire disk, the paid version allows "smart updates", which copies only files that are different, saving time) running on externally to perform the copy.

• Read/write port DAQmx questions

  Environment

  Windows XP SP3

  LabView 7.1

  NOR-DAQmx 8.7.1

  (2) PCI-DIO-96 cards

  I'm trying to move from the level of registry TDAQ programming DAQmx and give me an "intensive" in mx.  I'm not sure about a few things.

  I need to put in place 20 channels/tasks that will run a mix of single, large port (8-bit) bed and written.  Some will be handshaking (82 c 55 mode 1) and some no handshake (82 c 55 mode 0).

  The plan is to create all tasks during an initialization routine and save the names of global tasks.  I open the task after creation and use the globals during the main part of the program execution, when I make the reads/writes on the port.  The body can run for hours at a time.  When the main is closed, the stop routiine close all tasks to exit ahead.

  Regarding the task creation/destruction - is it safe to create tasks and leave them open, or should they be created and destroyed every time that a write is performed?

  Regarding the port reads/writes, I suppose that when a port single read/write is made, there is no established buffer.  Is this correct?  Specifically, if I use the method above and leave task open, is it possible saturation of buffer or something similar to happen?

  TIA

  Charlie

  Regret - Yes, you said 7.1 - I can't keep back away, but here is a screenshot

  

  And - the task is saved outside of LabVIEW, so it's not really 'Open' or 'Closed', even when programmatically, create and destroy jobs.  Tasks exist or do not exist.  If they exist and have no errors, they can be run.

  Tampons are to move data to and from the device.  For static DIO, this isn't a problem.  You CAN run into problems with a task of acquiring buttons if it acquires data as soon as you read the data, but you can work around this by starting and stopping the task properly.

• In the target FPGA read/write control function?

  Hi people,

  I learn a lot from the sample project FPGA, including how you can easily retrieve and set controls and indicators in an FPGA using the read/write control function running in an RT target.

  However, I can't find a way to do something similar in a FPGA target.  I've been down this road before - that is, trying to move the data in/out a looping VI FPGA (void) to a (parent) FPGA VI - where my memory points to reach what I needed use.

  So I was happy to see the palette FPGA enabled me to drop the control functions to read/write on a FPGA vi target.  But alas there where tons of errors (not compatible son for target, etc.) and I guess now it's not possible.

  So, just to be sure, I'm not missing something, is there something like control functions to read/write to use in an FPGA for read/write in an another FPGA (looped)?

  In addition, why would I be able to read/write on a FPGA vi control functions if they are not supported?  (Sorry for the n00b question)

  Thank you

  Steve

  You're right that I don't have this knot in my palette.  However, I also do not seem to have a Refnum Occurrence in the palette is in the FPGA (see below), but I need to synchronize several loops of FPGA and added research using the textfield in the VI editor (and if compiles and runs).  So 6 months to Labview and I'm fuzzy on how the palette is restricted

  I don't know what you're trying to prove here. There is no control of refnum in search in your image. Occurrences are available in FPGA, and for control of refnum for one you just right click on a function of the instance and create a control. If you can create a valid thread of a certain type of data, then you can create a control or the indicator for it, regardless of the question to know if this type of control or indicator appears in the palettes. However, the functions that you can use in the block diagram are limited by what is available in the palettes.

  Regarding orders read/write for the FPGA/lights, I'm surprised that the infrastructure developed to allow read/write between RT and FPGA has not mobilized to allow read/write between FPGA and FPGA.  The elements of memory function, but they are less convenient.

  You may have noticed that you cannot compile the individual parts of an FPGA VI and combine them later; This is because when you compile an FPGA VI, all its subVIs are essentially merged to create a single block diagram (with additional logic if one not reentrant Subvi is used in multiple locations, this is why it is not recommended on FPGA). The subVIs no longer exist in the FPGA compiled; reading and writing a control on them would make no sense. If you want similar behavior, use global variables - but understand that global variables store values in FPGA logic resources. Using the elements of memory (or FIFO, which can also store in memory) leaves more fabric available FPGA logic by storing data in resources specially designed for this purpose.

• Frequency of calls to control for the FPGA read/write

  Hello

  I use a cRIO-9076 with a module NI 9476 DO spend some faucets. It is sometimes necessary for faucets with a pulse time down to a few ms of impulse.

  The FPGA VI Gets the power tap queries, executes a logic of security, and routes the numerical results for the exits. It gets applications power of the VI on RT target that uses the function ' Read/write FPGA control' interaction programming of the FPGA VI front. The loop on the RT runs with 1 kHz, no iteration is missed. That means, it should be possible to switch the valves with a resolution of 1 ms.

  What I see on an oscilloscope, is that the output digital are high for multiples of 50 ms, the system does not reach the valve for example 80 ms pulse or pulses shorter than Ms. 50 is a kind of limitation for calls of "FPGA read/write control"? I tried both options for arbitration, but it does not help.

  The best knowledge of the limiting cRIO/module/features or ideas? Thank you in advance.

• Can we read/write in native application of contact?

  Is it possible to read/write the native application of contact using the android runtime? The api says it succeeds, and if I dump the db slider in a newspaper, it shows the recording, but the native application of contact does not show recording.

  If I make a new record using the native application of contact and then launch the android application and empty the db again, it does not show the contact, I added, which makes me think that they are separated.

  Is it possible to read/write in the native application of contact? The Simulator says it of an Alpha, is this something that will work on a real device of BB 10?

  Hello

  Currently, we do not support the read/write in the Native contacts database. For android, you can add the phone number and e-mail to existiing contacts, but not create new ones.

  It is something we are looking to support in versions of features.

  Thank you
