How to read two counters and writing AO at the same time with 6024?

I use Labview to read two quadrature encoder outputs and I use the two
counters
of 6024E for this. I can read the encoders continuously. I also want to
send an
analog output with a period of 30 miliseconds
while the reading of encoders is continuouing at the background. How can I
do
this. I searched the NI discussion forums and found that my device have
only 1 DMA channel. Is it possible to overcome the problem using
interrupt??(set device information.vi) Is there any example code about this
problem?
Thanks a lot.."

Hi Ress,

    Is the iPad charged?  Plug it in with the charger/wall outlet for half an hour and try again to reboot by holding both the power and home buttons until the apple logo appears.

  • How do I make Organizer and Editor open at the same time?

    I'm new to PSE 10 and want to know how to make Organizer and Editor open at the same time. I can get the Organizer up, but have to pick out a photo and click on Fix: Full Photo Edit to get Editor to open. Is that the only way to do it?
    Thanks,
    K

    Create Desktop shortcuts for the Organizer and the Editor:
    The Editor's executable is:
    "C:\Program Files (x86)\Adobe\Photoshop Elements 10\PhotoshopElementsEditor.exe"
    The Organizer's executable is:
    "C:\Program Files (x86)\Adobe\Elements 10 Organizer\PhotoshopElementsOrganizer.exe"

  • Acquire Analog and Digital inputs at the same time with 6025E card

    I have 6025E DAQ card, all the analog channels are used
    up. There are several digital signals, such as flowmeter. Can I acquire both kinds of data at the same time with my 6025E card? Thanks for your help.

    I suggest you search the examples that ship with LV
    Digital
    Find Examples>>>Hardware Input and Output>>>Digital Input and Output>>>8255
    for doing each type of I/O seperately.
    When you have found two examples. Just try to run the two at the rate use need in your final app.
    Post follow-ups Q's here. I am not personally familiar with that deveice so I can not speak from experience.
    I would generally expect that if you sample rate is low (i.e. <10Hz) you maybe happy with the results. If you want to run faster or have the PC do something else at the same time, the timing of the signals form the DIO lines may be suspect.
    So...
    It depends.

  • How to print both letter and legal size docs at same time with two trays

    I have an HP Laser Jet P2055dn printer. How can I print both letter and legal docs at same time?

    Not quite sure what you mean by "print both letter and legal docs at same time".
    If you mean that sometimes you want to print a document on Letter size paper, and at other times you want to print a different document on Legal sized paper, then all that is neccessary is to ensure that:
    The printer knows what Paper Size (e.g. Letter or Legal) is present in each tray; on many LaserJet devices, the size is detected automaticaly by sensors in each tray (except for the drop-down tray), but some devices may require that you set the size via front panel menus, or (for network models) via the Embedded Web Server equivalent.
    You may also need to specify what Paper Type (e.g. Plain or Letterhead) is present in each tray, in order to distinguish between two or more trays which have the same paper size loaded.
    Within your appllcation / print preferences, ensure that you select the required combination of size and type for the document.
    But if you mean how do you print a document with some pages on one size of paper, and other pages on a different size, this may only be possible with bespoke applications and/or printer drivers.

  • How to listen to music and record sound at the same time

    I want to figure out a way to record sound and listen to my music at the same time. Most recording apps stop my music when it starts to record and I can't find an app that does both. Any ideas?

    Not possible since the iPod only has one audio processor.

  • How to check 6 digital signals change value at the same time with PCI-6229??

    I am using DAQ card PCI-6229.
    Channel 1 generate a digital signal.
    Channel 2,3,4,5,6,7 acquire digital signals.
    I want to check:
    1. Whether the rising edge of Channel 2,3,4,5,6,7 occures at the same time;
    2. The time delay from the rising edge of Channel 1 to the rising edge of Channel 2,3,4,5,6,7 is within a certain range.
    I know I can use counter to get the two edge seperation time delay. But I only have two counter, it is two time-consuming if I check one by one.
    I don't know how to check the rising edge of 6 different channels occure at the same time.
    Does anyone has any suggestions?
    Thanks

    Hello,
    You can use the DAQ card's digital input change detection circuitry to detect changes in the input, you can then use a counter to measure the relative time between samples. Please read Page 6-9 DI Change Detection Applications for more information. Let me know if this helps

  • Can I use Lightroom on my mac and my pc at the same time with only one subscription?

    Hello everyone,
    for five months now I have a Creative Cloud subscription for Lightroom and Photoshop. Till now I was just using it on my PC. Now I've bought me a MAC and would like to install Lightroom on the MAC either. Do I need a second subscription for MAC or can I use my subscription on the MAC and PC simultaneously?
    thx for feedback

    If you are asking if you can be running the subscription software on the two machines at the same time, the answer to that is no.  Per your license you can only be using one of the installations at a given time.
    If you are asking if you can have the software installed and capable of being used on both machines then the answer is yes... you just cannot have both machines in use  running the subscription software at the same time.

  • How to use two different versions of Firefox at the same time on Snow Leopard?

    I recently upgraded to Firefox 4.0 on my 27" iMac running Snow Leopard 10.6.7.
    Previously, I was using Google's "Page Speed" along with Firebug in Firefox 3.6.15 to optimize images in my web pages, and to find other areas to optimize.
    Page Speed is not yet compatible with Firefox 4.0. I wrote to Google about this some time ago -- no answer yet.
    If I run Firefox 3.6.15 in order to use Page Speed, I run into a few problems afterward when I start using Firefox 4.0 again, since they both use the same "Firefox" folder in my "Application Support" folder.
    How can I set it up so that I can have two separate "Firefox" folders in my "Application Support" folder?
    Or is there an easier way to use two different versions of Firefox simultaneously, even if one has extensions and/or plug-ins installed which are not compatible with the other version?
    Thanks for a great browser!

    Please disregard my question. I just conducted more web search and learned how to use Firefox's profile manager in order to make a separate profile for Firefox 3.6.15.
    You can find instructions on this page:
    http://support.mozilla.com/en-US/kb/Managing%20profiles#os=mac&browser=fx35
    '''A small tip:'''
    If your Firefox app is named anything other than "Firefox" -- say for example "Firefox 3.6.15" -- when you follow the instructions at the above link, make sure you escape the blank space that is before the version number by adding a backward slash before it, when you type the command string in the Terminal. In other words, in that string, you should use this:
    Firefox\ 3.6.15
    I hope that helps someone.

  • I'd like to sync two videos and edit them at the same time, possible?

    I've recently recorded a conference speaker with a camera and a screen capture of his slides I'd like to import the two video files and sync them together (they received the same audio feed) then perform very basic edits of removing any intro before the speaker and the q&amp;a after his talk. Any tips on making this as easy as possible would be greatly appreciated. I need to have a copy of each video (headshot and screen capture) that is the same length.

  • How do I bounce audio and midi tracks at the same time to burn a CD?

    Hi there,
    I would like to bounce a song with both audio and midi tracks recorded in it onto a CD.
    Despite ensuring that I am doing a realtime bounce (not offline) I am only getting the audio tracks burnt onto the CD - the midi isn't getting bounced to the final output.
    This must be a stupid question, if someone would be so kind as to give me an obvious answer I would be most grateful.
    Thankin y'all
    amata

    Hi A,
    if you use the instrument (with logic virtual synths) tracks for midi,
    it will.
    BTW, why don't you do it offline?
    It will be so much faster.
    Kindly regards,
    Jorge

  • Bluetooth keyboard K810 and mouse T630 at the same time, repeating keys and mouse starts to stutter

    I use a Lenovo Thinkpad Tablet 2, Windows 8.1(core edition), x86 (32bit).
    If I pair a Bluetooth keyboard K810 and mouse T630 at the same time, with Wifi On, the keyboard starts repeating the keys and the mouse starts to stutter. Especially if WiFi is under load (when downloading something).
    This doesn’t happens if I pair only the keyboard, or if I pair mouse and keyboard with Wifi OFF.
    If I pair a Bluetooth keyboard and use a USB mouse with Wifi ON, everything works fine.
    If I pair a Bluetooth mouse and use a USB keyboard with Wifi ON, everything works fine.
    I think it is an issue with two Bluetooth devices paired at the same time with Wifi ON.
    So here is a summary:
    BT mouse and BT keyboard / Wifi ON ----> repeating chars and the mouse starts to stutter (bug)
    BT mouse and BT keyboard / Wifi OFF ----> works fine
    Only BT keyboard / Wifi ON ----> works fine
    Only BT mouse / Wifi ON ----> works fine
    USB mouse and BT keyboard / Wifi ON ----> works fine
    USB keyboard and BT mouse / Wifi ON ----> works fine
    Where is the problem? Is there any solution?
    Solved!
    Go to Solution.

    I have solved the problem. In the Wlan-Drives-Settings there is the "Bluetooth Collaboration" option. I put the value to "Disable" and now works everything like charm.
