• LabVIEW USB-6366 sample 2 AI and encoder value triggered with X 1-Encoder (not with the sample clock) - need help, please

  Hello world

  After 10 years of LabVIEW experience I'm totally lost.

  It's my first project with DAQmx and I do not know how to handle.

  My configuration: Windows7. LabVIEW 2012 DevSuite; X Series USB-6366

  My goal: trigger value encoder and 2 inputs analog

  I would get a result for the value of the encoder and each of the two analog inputs for each change of the value of the encoder (not more! I do not want to sort a huge amount of data afterwards)

  I was able to configure it with the measurement and Automation Explorer, but have no idea how to do that in a LabVIEW configuration.

  Read all of the examples I could find the analog inputs and the encoder with SampleClock. This isn't what I'm looking for.

  I would be very happy if someone could guide me to my solution.

  I have attached the confiuration exported from the measurement and Automation Explorer.

  Thanks in advance, best regards,.

  You'll get there, but yes, the first exhibition to DAQmx is probably a little overwhelming.  A few other tips based on your screenshot (I'm on LV2010 & can't open the code).

  1. "allow buffer overwrites" is that a functional but description is not text.  It lies under the Read DAQmx property node and must be configured before starting the task.  Here is an excerpt:

  

  2. it is usually (but not always) an available timing system to be used for all HAVE channels in a task just by the material.  As a result, all channels to HAVE should be included in a single task.   You can do this easily in chaining your call 'DAQmx create Virtual Channel' twice the job output and input/output error.  Because the second call will receive a task refnum as input, it will configure the 2nd channel of AI to be part of the same task.

  (It is possible to specify just several channels in a single call, but separate calls gives you the ability to configure different setting on the scale or range of entry).

  3. the 'random', which IA task gave you the error is due to the lack of sequencing in your attempts to start tasks.  The question which is the fortunate success that happens to run first can (and does) vary from run to run.  By combining the two channels to HAVE in a single task, this problem will disappear, but you want to be sure that the tasks of the AI and the counter are started * before * any clock signals come to PFI8.

  4. "change detection" will be available for digital input assignments, not tasks of meter.  And it is also generally supported only for a digital port a-bit value.  Other ports then that support data acq clocked by the software on demand.  I guess one of these questions is the source of your error.

  On the boards of the M series that I used, change detection has been supported only on port 0 - I think that the same thing will be true for the X-series cards.  The following took place without error for me using a simulated X series device.  By selecting another port gave an error.

  

• Trying to simulate the device USB-6366 (without success)

  I read through the tutorials DAQmx and MAX about the simulation of the device, but I can't yet find a way to effectively simulate the acquisition and generation of a signal using a device USB-OR-6366.

  I am a (given at the entrance of this VI) signal using DAQmx Write and then use DAQmx Read to read the signal captured from the internal memory of the card (which has a buffer of 32 MS). To do this, I created a task with DAQmx I feed in the writing block.

  I know that the approach is most likely wrong, but I can't understand not just how to do this in a simple way and documentation of NOR is anything but simple. All I want is to

  (a) test using 2 digital inputs to capture this signal by the device and then read what she has gained from its internal buffer

  (b) send the same signal to 2 digital outputs the signal output again.

  See you soon

  Yes! the simulation is designed to allow you to write a program and check that it works theoretically even if you do not have the material physically available. It has no interface programming to influence on the what the reading functions will return simulated data. And write the function has no notable effect anywhere, working as a receiver of data in nirvana. It is always useful because you can test software without getting all kinds of errors on the non existing hardware access attempt, but it has its limits, of course. However, a programming interface for manipulating that which and how the data are simulated, while it would be a very interesting feature, is almost certainly to complicated not only to implement but also to use.

• The value of static output on PFI on USB 6366

  Hi all

  What I want to achieve is to save dedicated 8 DIO lines on dev USB6366 on port 0 for some specific application and use remaining 16 PFI lines control some external equipment.

  All I need is the ability to set some PFI line high/low within a reasonable time by command software (LabView, .net, C, whatever). No requirement special timing, just set some PFI lines high and LOW back switch after not less than 20 ms. These signals would be used to control an external logic; no significant current.

  The question:
  Is it possible to control the PFI lines in the way that I described on 6366 USB device?

  Manual for this device (or in fact, the family of devices) is a bit ambiguous on this subject.

  It is said it is possible to select 'direction' of each digital line but that's it. No more information. Only a manipulation of the port 0 (general purpose DIO) has its own section. PFI-Out is just mentioned. PFI - In is explained a bit more in detail, but also vaguely.

  P.S. I have no devices available now (I would have tested the ability to do what I described, if I had).

  Thanks for your time!

  Bebor,

  You should be able to use the 16 PFI lines as digital lines.  To change the status of the lines, you must create a task of digital output, the same as you would on the lines of port 0 (DAQmx manages the programming of the direction of line for you when you create a task).  Writing DAQmx can then update the status of the lines.

  These lines do not support the operation timed, so lines are updated when writing DAQmx is called.  Synchronization restrictions that are imposed should be dealt with by your software and will be limited to the accuracy of the software timers put at your disposal.

• Digital and analog generation and acquisition using USB-6251

  Hi all

  I have to actually synchronize a 6251, USB and USB 6366 Board. I have a vi, which is good that now I am able to use the 6366 as the master and as slave 6251, attached tie. The master generates a digital trigger for (generation synchronization) pulse and the acquisition of the signals on both cards, analog signal ramp and acquires signals. The slave acquires only a series of signals after outbreak.

  I want to have the 6251 as master and as slave 6366. The vi attached the other way around as I mentioned above. When I try to use the 6251 as the master, I get an error asking me to specify the clock source (I did the material and some changes in the program as well, as export properly 6251 at 6366 clock).

  Thank you

  SANJU

  Thanks for your reply jonathon,

  But in your code below, I coudnt get the Outpput internal PCI-6251/ctrl0...

  but I hardwaired the o/p (PFI 12) meter... .and generated a signal meter on this port, I used that as the clock...

  Thank you

• Reset the multifunction data acquisition?

  A call to 'DAQmx Reset Device.vi' resets all modes of hardware DAQ Multifunction or only those that are associated with the task that is connected to the entry? In other words, if the material includes analog outputs, analog and e/s digital, for example, the reset apply to all modes or only those that are associated with the task of entry? In this case, it's a USB-6366, but the question applies to any Multifunction DAQ.

  Thank you
  Don

  The whole device is reset to zero. Why do you need to reset?

• How to set system clock?

  Hello

  I am desiging a program LabVIEW which will measure data of an NI USB-6366, make some calculations and then copy the corresponding data.

  For the moment, I'm just doing will vary from data with a sampling rate of 20 kHz. I'm storing the data and the corresponding time (in milliseconds) in a table. I noticed she was taking about 5 to 30 ms to get some values. It is very slow for my project needs (I need a resolution of about 100 microseconds)

  Some info:

  -When you run the code, just all of the CPU resources are used)

  -Fastener is the vi

  -J' use:

  * Trial LabVIEW 2013 (32 bit)

  * Windows 7 Enterprise Edition (SP1) 64-bit

  * Intel Core i5 CPU to 2.40 GHz

  * 4 GB OF RAM

  Is there a way to set a faster system for execution of the program clock?

  Thank you

  I just got a PM from the OP ask for an example.

  In other words, there are two options:

  (a) stick with the DAQ assistant. Wire dynamic data for a graphic indicator directly or use the function "Of DDT" L'Express > range of Manipulation of the Signal. Configure it in order to extract a waveform to keep calendar of data acquisition information.

  (b) preferred recommendation: use the finder of the example to find examples of I, continued and finished. Open them and configure everything to your taste on the front panel and run the example (s). Look if it contains the information you are looking for. If it is like that, study of the code. If not, come back here and describe what functions these examples to your needs.

• USB disabled after the update of the Sierra (a short circuit and a work)

  Hi, when I bought my mbp 13 inches mid2012 (used, not new) I noticed that a USB port did not work. In the Yosemite sometimes I noticed that a USB port consumed too much energy and have been disabled. (I think because the usb port has been short-circuited. Year when it was time to update the mbp to El Capitan I had a few panic the kernel and the newspaper was shown as the last driver loaded the USB driver, so I kept the mbp with Yosemite. A few days ago, I updated for Sierra but only usb which used to work stopped working. It has enabled and turned on but Finder and disk utility does not see the drive. In an Apple dealer they said that could be established relationships with some oxide and next week will take it and see what the problem is.

  If there is someone with the same problems, please tell me what to do! I don't want to put in the trash my mac just for a flash drive... but I need!

  Hi Supermene,

  Thank you for using communities of Apple Support. Based on what you said, it appears as a USB device is not recognized in one of the USB ports. There are a few things that can cause this. I recommend you read these articles, which may be able to help solve the problem.

• New Audio USB Interface lose sound on El Capitan

  Hi all!

  A few weeks ago that I upgraded my MacBook Pro retina 15 "end 2013 to El Capitan, after that my USB Audio Interfaces (Focusrite Scarlett 2i4) and Safire 6 USB stopped working properly. Both work correctly when they are connected to an iMac 5K running the same operating system.

  I can listen to Audio for some time (about 10-2 Minutes, it is always different), when the Audio starts to crush und get outs, after a certain time there is only silence "click on" come out of the speakers.

  Heres an Audio file of the sound that results from: https://www.dropbox.com/s/5nb96bmdh47kmi2/20160923%20141619.m4a?dl=0

  I already tried to reinstall OS X (starting with CMD R and reinstall OS), reset PRAM and SMC. Nothing has changed the question. Any ideas where it comes from?

  Greetings

  Chris

  It is most likely a software conflict. Note the time at which audio is running out. Open the Console and look for accidents or mistakes at this time.

  The reason why it crashes on a mac, but not the others most likely is related to differences in software installed. Run Etrecheck on touch mac and post the report here.

• Crash when disconnecting USB connected to the Steinberg UR-22

  Updated for Sierra recently.

  When I unplug my Steinberg UR-22 by the USB port, the operating system crashes instantly and restarts.  EVERY TIME.

  I plug/unplug often and have never had this problem until the Sierra.  I use my Air for labor and for the game, so he forces me to move to and from the Office to Home Office... or around the House.

  Any suggestions?

  Thank you!

• USB charger - 29W C - compatibility with 12.9 "iPad Pro

  I'm looking for an answer as to if the USB - C 29W charger is compatible with the iPad to 12.9 "Pro. I know this question has been asked and answered by the communities in the past, but when I went to the Apple Store to buy the charger today, the staff told me that the charger could damage my battery over time. I then started a support chat session to confirm the answer and the representative said (and I quote) "If 2 people advised me not to do something, I would not even waste my time." We could care less if you want to damage your unit. »

  First of all, I never got a rude responses to Apple, so it was a surprise. Secondly, I really just trying to get an answer to the question. Can anyone (especially Apple) help out me? Thank you!

  If it is not in the specs of the iPad, you're crazy to use it. The Chargers are cheap, the iPad is not.

• Can I create a recovery bootable USB through disk utility?

  My HARD drive is dying, I can't access my Macintosh HD partition anymore and I can't reinstall OS because I SMART errors. Before the format and reinstall the attempt to load slow my computer, random errors, etc. So I definitely think that the HARD drive is near death. My plan is to replace my HDD for a Virgin SSD, I perform this task several times on computers of the victory but for MAC, I wonder how I will load the new OS. Can I make a bootable USB with the recovery partition, but on a USB key tools? Unofrtunately I have more available Mac to create the USB bootable through itunes.

  My computer is the MacBook Pro (13-inch mid 2010), I have also all original packaging somewhere, if there is a CD that I can use, I certainly can get too.

  Any advice?

  Thank you!

  Apple have this to do a USB installation...

  Create an installer for OS X - Apple support bootable

  Another option is to use the diskmakerx.com application

  You must have the OS installer downloaded to make these methods of work is probably not practice on your failed drive.

  Both of these options are to run a 'normal' operating system too. The recovery partition is not 'normal '.

  Another option is to use the Internet recovery mode if your Mac supports...

  Computers that can be upgraded to use OS X Internet Recovery - Apple Support

  On macOS recovery - Apple Support

  Use wired ethernet for best results, since it will download a bootable OS & then download the installer of the OS also.

  I suspect you have the update of the firmware installed to add this feature if it has been updated over the last 3 years

  You may be able to generate a score of alternative recovery to another disk (such as a USB key) If you want to just "compensation of base OS.

  OS X: on Recovery Disk Wizard - Apple Support

  A last solution would be to clone your drive failing on an external drive (or use the new SSD in a proper case). That can be done in the modes of recovery via disk utility. Basically, you use a feature to "restore" to clone one volume to another. (I don't see clear instructions for the moment so ask if you want to pursue this option).
