Delay in polling DIO

Hello

Im am voting a DIO used as a trigger. So basically when the digital line goes high (true - boolean), my program acquires some AIs and two measurements of pulse width using a meter. It seems that the counter displays an incorrect value for a reason any for the first measurement of pulse duration. Ive tried to measure separately - pulse width i.e. without vote the DI - and it works very well, but for some reason, when I asked the DI, he stops the calc of pulse to operate correctly

any ideas?

see you soon

Don

Hi Don,

It seems you could do arm beginning of trigger using a meter. Ni.com research for "outbreak of starting arms ' can be a good start to find more, but here are a few links as well."

  • entry of the FPGA 9402 trigger cRIO 9064 on DIO does not read

    Hello

    I have a cRIO 9064 using the Module C 9402 as a quick DIO in a SCTL. I use it in a (GPDD) digital delay pulse generator.

    I've successfully the GPDD, triggered by a square wave generated internal, clocked at 1 MHz.

    and I measure the pulse output perfect on an oscillascope.

    My implementation is actually a clone of in: http://www.ni.com/example/31131/en/

    However, when I try to trigger from an external 1 MHz, 6 Volt amplitude; duty_cycle 50%, square entering the DIO3 wave

    There is no trigger, as seen on the Ticks_Between_Trig - which should be around 40, when it is correct release.

    I used the method "Check status" to make sure that the 9402 is ready before the SCTL.

    (Note: although it is labled Mod3 in the screenshot, it is actaully Mod1 and it simple namign incompatibility - which, once set doesn't change anything.)

    I see not all digital HIGH when the input trigger control, what I do when you use the internal trigger.

    The LED flashes, quite often even if actually at 1 MHz.

    My question is what thing I must have the DIO 9402 read the input signal.

    I followed the instructions here:

    http://zone.NI.com/reference/en-XX/help/370984R-01/criodevicehelp/cRIO-9402/

    but maybe I missed something.

    Thank you

    Resolved,

    I had a bad input pulse generator which was flacky.

    When I check the amplitude of the pulses on an oscilascope but a day later, when I corrected my code to include the ready method of Module C.

    the amplitude of impulse was not working, but I've always tried to test with her.

    Finally I double checked on the oscillascope again the trigger signal to find not suffecient.

    Old eqiupment... then the warm-up does not.

  • Detection of changing DIO PCI-6035E

    CVI 8.1

    PCI-6035E

    Ex: ReadDigChan - ChangeDetectionEvent.c

    When I try either configure a DAQmx task in this application example or MAX

    I get this error:

    Error: Requested value is not supported for this property.

    Property: SampTimingType

    You asked: change Detection

    You can select: on request

    I am creating an application in which a task DAQmx monitors

    a single bit of DIO via an asynchronous callback function.

    Any ideas?

    -Chet

    Chet,

    Please post on the Forums of NOR. I was able to look into the problem you encounter and this is because the E series devices do not support ownership of change detection. If you simply try to monitor a bit, you will need to use polling to determine when the forest has changed and then perform an action, once you determine that the ILO has changed. Let me know if you have any other questions.

  • BlackBerry Z10 15 minute delay to receive email from GoDaddy IMAP?

    My Z10 seems only to check my account (GoDaddy) IMAP for new e-mails every 15 minutes. The account used to immediately download new emails when I got my 9780 last month.

    I know BB10 does not support the BIS, but he can still push. So what's happening? Why the delay now?

    Can I activate IMAP idle solve this problem? Anyone here experience with linking an IMAP of GoDaddy account for BB10 device and get email quickly (within 20 seconds)?

    BB10 suports push but only if the e-mail service provider allows. GoDaddy does not have push email POP or IMAP. GoDaddy has helped push only for its exchange e-mail servers.

    Therefore, it is necessary for the Z10 keep polling the server of mail at regular intervals. The interval can be defined as described in the previous post.

    In legacy devices, the BIS server used to make the terms of the vote and push e-mail each time that an email would happen. Here, push was possible on the servers who did not support push earlier.

    Implementation of Adobe to open the connection software has created more problems than it is worth. I use Photoshop, Bridge, first and every day hearing as part of the same project, all related. I thought I would put them in place to open the connection, to save time.

    However, the location of the Cache for all download and also the folder for my Google Backup Drive, on an external drive, and if it is not present when the software tries to open, things go haywire.

  • very long delay before printing

    My MacBook Pro is around the age of 18 months. It is updated at El Capitan.

    Maybe a week or two ago, my printer stopped printing normally. I bought the printer at the same time as the Mac. It's a HP Officejet 8610. It is connected with a time capsule wireless newish.

    When I select print, a normal icon on the dock. Opening it displays a message to printer, printer not connected. I fought with him for half an hour or more, then give up in disgust and head to do other things. When I return to my office, there is the impression.

    I deleted the printer in system preferences, then reinstalled. I have reset the airport utility. I turned the printer on and outside.

    I believe the delay between the choice of printing and when the printer starts his work about half an hour.

    Open system preferences > printers and Scanners and then select the print tab then check or right on the printer on the left then click: reset the printing system

    Then try to print.

  • There is Airfoil and Airport Express, latency/delay time?

    I want to be able to direct the output of my iMac "end 2014' 5K (10.11.6) on my stereo system (ParaSound P3/A23) using AirFoil 5 with Airport Extreme > Airport Express."

    But the audio output should be "real time." in other words, no delay or latency at all. Both are in the same room!

    I use notation software (Sibelius) and need to hear what I write immediately. Unlike streaming where I think there is an acceptable delay (2 seconds?) for the buffering?

    Is this possible please?

    If it isn't with AirFoil, any advice on how welcome :-)

    I want to be able to direct the output of my iMac "end 2014' 5K (10.11.6) on my stereo system (ParaSound P3/A23) using AirFoil 5 with Airport Extreme > Airport Express."

    With AirPlay (or Bluetooth), there will always be a form of delay or latency with streaming audio.

    In this scenario, an audio stream (on AirPlay) will go first to your iMac to AirPort Extreme and AirPort Express Terminal.

    To help understand why there will be delays, let's look at high-level "behind the scenes" about how works AirPlay:

    For the AirPort Express (AX), audio input is provided mainly by iTunes. Of course, it can also get feedback from other sources as you know, as of Rogue Amoeba's Airfoil.

    For streaming, iTunes or wing does most of the work. What is app reads audio content standard (AAC, MP3, audio books, Internet music streams, etc., it decompresses these file formats and creates what is essentially a raw, uncompressed audio stream.) This stream is compressed using Lossless Compression of Apple (via a QuickTime codec), encrypted with AES 128 bits and then listened (airplay) with an AXE. The stream is buffered for about 2 seconds until the stream is sent. The AX deciphers the flow, decodes and exports in a digital or analog PCM (using a built-in DAC) flows to its audio analog-to-digital versatile optical port.

    So, with the above, you can see that the tone does not simply move source to the destination without much more things. You will not be able to entirely eliminate the delay. Sorry!

  • Office 2013 on Win7 using bootcamp has delay time

    I use Win 7 teacher on a piece of Macbook Air 2014 with bootcamp 5 and MS Office 2013. Up to 4 weeks everything works well, and the performance was great. And then I got the delay time:

    -Closing remarks is the longest in about 4-5 sec

    -editig one Excel cell and switch to another will cost about 4 to 5 sec

    - and so on

    Thanks to this performance, it is horrible to work. I have also removed Office and install it again without any result.

    Anyone have some advice for me? Is there some patches in which software never cause this?

    Or am I alone with this?

    THX in advance

    Frank

    Your is no longer in a Mac environment, if this side of "windows" because you're not virtualize, you run Windows as a complete solution for Windows. OS X doesn't play not any part of your experience. Windows as OS X should be updated with patches and update securities, the latter is the only support Windows offers for Version 7, it is out of development and was removed by Microsoft for more than a year. All compatibility fixes should come from Microsoft, see microsoft.com for the availability of these.

    Outside the correction and the issues pourraient be caused by:

    Disk fragmentation that is common in windows. (However it is not under OS X, don't defrag on Mac, OS updates will do everything if it you better than anything you can buy)

    hard disk-ragmenting https://support.Microsoft.com/en-us/help/17126/Windows-7-improve-performance-def

    Font management (again, on the side of 'Windows', your OS X fonts do not play in this)

    3rd party Windows applications, such as anti-virus and the litany of bloatware inherent with Windows. Windows has a startup mode for troubleshooting.

    https://support.Microsoft.com/en-us/help/17419/Windows-7-Advanced-startup-option s-safe-mode

  • Follow-up of applications for security delays

    When you use the private mode on http://www.lensbest.de/ with activated protection of follow-up, most of the requests are delayed by 1 to 2 seconds. Loading animation is not present in this time interval. For example, the links in the menu and in the footer are affected by the problem.
    If I disable the protection followed in the address bar, the delay goes away.

    I found the problem in Firefox 42. Firefox to reset to the default values and creating a new profile didn't help.

    I can do something on the server to resolve this problem?

  • Is currently plagued by the same problems as a Firefox verion it is - delayed tab swtiching paint, etc. of Thunderbird?

    You know, sometimes I'll go to the Lightning Calendar tab and he painted nothing, but I'll move my mouse and to color elements such as the individual calendar days. Very weird, but I know that Firefox has recently set it exactly the same problem of what they see as a 'condition' (see bugzilla #1067470)

    I have the "TT DeepDark" theme but I have confirmed that the problem is still present on the default theme as well.

    (Delayed) Update: looks like to me that this has been resolved in silence with the version 38.1.0, released July 9, 2015. Initially, I thought it was a question of OC with my gpu, but after additional testing, which was not the case.

  • Internet access with delay on safari

    I use a connection high speed fiber optic. My network is configured as below, located in a two-storey house. The apple express is on the 2nd level:

    For some reason any the everytime I open a Web page, it opens with a delay - i.e. After you press ENTER, it puts on hold for 10 to 15 seconds and then the page will open. This only happens if I open the page first time in a session. If I close and open the same page after a few minutes, it opens instantly, but if I open the next day, then again to delay. This only happens on the Imac connected on 2nd level. MacBook connected via the wireless at level 1, no problem.

    I tried to solve the problems, but no effect.

    -changed the DNS setting, after looking for a closer and faster server.

    -reset the apple express.

    any ideas, on how I can remedy this. Thank you
