• With a sampling of the data with DAQMX, error-200279 occurs when making 2d array dbl

  Hello

  I did a system of simple analog voltage with DAQMX data acquisition.

  It is made for reading of capacitance, where output capacitance value out of a circuit in the periodic voltage signal.

  What I want is to get data from four capacitors simultaneously through four channels, using samples n n (dbl 2d).

  The structure of my VI is almost similar with examples of continuous sampling of voltage in LabView, with the exception of a few other calculations in the loop.

  And for the synchronization of the trigger, I've corrected the edge of release with the external signal from the capacitance reading circuit.

  Version no. 1 has a channel for data input voltage. Version n ° 2 has four channels for the input data.

  While ver.1 can get accurate reading of four capacitors circuit data each (a single channel at a time),.

  ver.2 acquires four channels of data, with a single thin data channel, all the others were wrong.

  I saw a 200279 error occur in the DAQMX read part 2d dbl, so I tried increasing the buffers by changing the sampling frequency or the number of samples, but it wasn't everything.

  I rose for most of the forums with the 200279 error, but the solution would not work on mine.

  Anyone can find the problem? I will attach my screws it may include a bit of Korean language, but most of them are in English, shouldn't be too hard to recognize. Sorry for the inconvenience.

  Oh I forgot, my DAQ is NI USB-6259, and it works in Win XP sp3 and LabView 8.6.

  Thank you.

  Hello Azurenight,

  The 6259 is a DAQ card of the M Series Multiplexed, which means that it is not possible to sample each signal at the same instant, rather the channels are all sent through the ADC even and must be sampled in order. More information on this can be found here:

  LabVIEW Help: Multiplexing compared with simultaneous sampling

  http://zone.NI.com/reference/en-XX/help/370466W-01/mxcncpts/multisimulsamp/

  It may still be possible to get the data you need with the card you have - could you give more information about the maximum eligible period between samples on different channels?

  If you require * real * simultaneous sampling, you will probably need different hardware.

  Kind regards

• Multitask with daqmx

  Hello

  I am currently working on a Senior design project where I have to measure rpm, torque, pressure and temperature.  I use strain gauges, pressure sensor and a Hall effect sensor, thermocouples for these readings.  A myDAQ collects readings rpm and pressure while a cDAQ collects couple and readings of the temperature with NI 9211 and NI 9237 modules.  I have created LabVIEW screws for each sensor and they work.  The problem I have is when I try to create a VI with DAQmx who reads all the values of these sensors simultaneously.  The VI I joined randomly displays one of the measures while other measures remain empty.  How can I change my VI so I can show all my readings at the same time?

  Yes.  Create multiple tasks, where all the strings that are common to a specific device are grouped in the same task.  Then go and run these tasks in parallel.  Do you need a precise synchronization between the tracks in the different devices?  If this isn't the case, then the method should work perfectly.  If you need a precise timing, things would get more complicated, but might not be impossible.

• Timing embedded with Daqmx on PCI-6132

  Hello

  My colleague and I are trying to make a program Labview which starts a timer when the first trigger (sensor) is struck and stop the timer when the second trigger (sensor) is reached in 2012. We currently have a program for her, but this program was not sufficiently precise. Also the current program is using the DAQ assistant, but we would like to replace with daqmx triggering. We have also tried to use the OnboardClock on the PCI-6132, but still could not do the work programme.

  Is there anyone who knows how to do this and could explain it?

  (In the attachment is the current program)

  Thanks in advance,

• How to associate the audio file with progress bar

  Hi all

  I have a case in which I need to associate an audio file with a progress bar. What I want to do is to able to read an audio file that will say "Started process..." "Continuous on" process ends and it is and must be synchronized with the progress bar. Is it possible to do so.

  Please let me know

  Thank you

  Ankit G

  Are you referring to a LabVIEW horizontal/vertical progress bar that basically an integer U8 constantly wrote in it? Is it in a loop as it fills?

  If so, there is a full range that allows you to listen to the signals. As you write the number of your progress at the helm, you can keep control of what the number is (structure of the event or case), and when it hits special values, you play special sounds. Here's a screenshot of this palette.

  

• How to acquire of various AI channels simultaneously with a different range for each of them?

  How to acquire of various AI channels simultaneously with a different range for each of them?

  In LabView, I found some examples but in C it is not seem to be any.

  Or you can add channels one by one with individual instructions: the follwing code compilation and runs without error on vitual DAQ hardware:

  ERR = DAQmxCreateTask ("", &taskH); ")
  
  ERR = DAQmxCreateAIVoltageChan (taskH, ' Dev1/ai0', 'AI0', DAQmx_Val_Cfg_Default,-5,0, 5.0, DAQmx_Val_Volts, "");
  
  ERR = DAQmxCreateAIVoltageChan (taskH, ' Dev1/ai1', 'AI1', DAQmx_Val_Cfg_Default,-10,0, 10.0, DAQmx_Val_Volts, "");
  
  DAQmxStartTask (taskH);
  
  ERR = DAQmxReadAnalogF64 (taskH, 5, 10.0, DAQmx_Val_GroupByChannel, val, 10, & read, 0);
  
  DAQmxClearTask (taskH);
  
  

• using male to 3 x female cable stereo Audio Splitter with audio output

  The HP Pavilion 22-h031ea all-in-one has an audio output on the back of the unit. Is this ok for this connect with a 6:1 with a male/3 female x audio cable with stereo Audio Splitter?

  Simmo56, welcome to the forum.

  I am not sure it will work.  However, it will not hurt anything to try it.  If this does not work, you will not be able to have 6.1 sound.

• Is it time stamp with daqmx read

  Hi all

  Simple question.  I have currently not creating a task or starting a task, I simply create a channel and reading that chanel.

  It is...  Why I don't get a timestamp when you do and do I create a task to get one of this?

  There is a timestamp when you use the DAQ Assistant or when you choose to return a data type of waveform with DAQmx Read.

  You can't do a reading without a blemish. You don't have to create the task in MAX, however.

• time of release with daqmx

  Hello

  How can I set the time of liberation with DAQmx?

  In general, with a single DAQ hardware, the two signals are connected at the same time and the acquisition time is a function of the sampling frequency and number of samples read. For example, with a sampling rate of 1000 samples/s and 50 samples, the acquisition will be 50 msec. You then get a returned array if you wanted to watch a single signal by iteration of the while loop, it is simply a matter of indexing the specific channel to the table. You must set the mode of continuous sampling to avoid gaps and precise timing. Using two separate tasks and switching back and forth would add a lot of overhead to close/create tasks and you have little control over this period.

• 2009 with DAQmx Installer

  We distributed an integrated application that uses DAQmx 8.x and LabVIEW 8.6 for several years.  I'll call the application MyApp 2.8.  We are working on a new version that uses LV 2009 and DAQmx 9.x, which we will call 3.5 MyApp.  When build us and deploy a Setup program for MyApp 3.5, then try to use it on a computer that already has 2.8 installed MyApp, the installer complains about dependencies and said that the two DAQmx 8.x and MyApp 2.8 must be uninstalled first.  I spoke NOR cela briefly and told me that DAQmx 9 was a pretty radical overhaul that required this change.

  It's annoying and slow for us, but almost untenable for our customers.  First of all, MyApp MyApp 3.5 and 2.8 are compatible, and we prefer to leave MyApp 2.8 installed as a backup as people get used to 3.5.  If the customer needs:
  Uninstall MyApp 2.8

  Uninstall DAQmx 8.9

  Install MyApp 3.5 with DAQmx 9.0

  Reinstall 2.8 MyApp (as if they can still find the disc!)

  Far too many steps and complications.  In addition, it is not really necessary.  If the runtime for 2009 is already installed on the computer (for some reason any), you can simply copy the MyApp 3.5 on the computer and it will run with DAQmx 8.9.  But this only postpones the problem, because at some point the customer will upgrade once again, and we will have forgotten that they were installed with a workaround, and...

  The really frustrating part is setup for MyApp 3.5 refuses to install until MyApp 2.8 is uninstalled.   While we have proven that MyApp 2.8 will work very well with DAQmx 9.0.

  Is anyone else noticing this problem?  Has anyone found any better workaround?  Is the same problem when we jumped 2009 and returned with 2010 and the last DAQmx?

  Thank you

  DaveT

  DaveT,

  You're right - for this aspect of the problem - my proposed solution won't help. At the price of a larger Setup program, including the full version of DAQmx probably will give the upgrade experience you want. If the web download size is a concern, perhaps you could provide two builds of your product - with the acquisition of complete data (for those of you who have your old product) and with smaller data acquisition (for those who do a clean install)?

  In addition, certain registry keys to remove the dependency I guess hacking is sort of an option, but it probably isn't the type of solution you are looking for. (We are currently researching the addition of some extra features in the uninstall program OR allow without taking account of certain dependencies, but nothing is currently available).

  Kind regards

• HP Envy 23 - K030: Audio problems with HP envy 23-K030 and Windows 8.1

  I read all the discussions on audio problems with the IDT High Definition Audio Driver and Windows 8.1
  I get audio on my speakers ONLY and not the headset.
  I uninstalled rebooted and reinstalled the correct driver by this web site of HP support for my machine.
  no luck - same behavior.
  
  The only thing that worked was the IDT driver installation and Windows device driver high definition.
  The headphone jack are properly behaved and everything is ok worked.  However, I lose the audio Panel BEATS and the functions of the Board of Directors of IDT.   (superior quality sound-even with the built-in speakers).
  
  An interesting thing I noticed, when the Microsoft driver is used (and work) on the control panel for this device, it presents "the left panel making" when the configuration screen for the 'speakers '.  for the official driver of IDT, it shows 4 outlets - none of them say "left sidebar", there's rear panel and a plug of façade.    On the old driver that didn't work, he showed "right pane" and there is no control on the right panel.
  
  I think the pilot is simply wrong of this material. The driver is to look 10/2013-it is as if it were updated for this model ALL in ONE - only when it comes to use the headphone jack.
  
  Is there a better driver (I can't "find one beyond 6.10.6486.0 or 6.10.6491 - both had the same problem.)
  
  I do not use my time to often-rarely-last helmet I used them they have worked. Now, they are not - a few automatic updates upset the balance of the force.
  
  Any help would be appreciated. IF not - it is a problem that a person should study.
  

  Also it is reproducible. I have install generic Microsoft driver-headphone jack works and the sound Jack not pregnant, I re - install IDT player - his fate only speakers and not jack.

  I thought about it.
