How to replace the output buffer?

I'm a generation of finite signals 2 lanes on a0 and a1. I want to change one or the other of the waveforms at various times during the program and sometimes I have to be able to overwrite the contents of the buffer with a new set of data until the generation has run. Should be easy, but so far I have not figured out how do.

When I try, the first attempt to crush the buffer I get error-200547 occurred .vi DAQmx Write (analog 2D NChan DBL NSamp) that says full buffer, cannot write more data until the task has been executed.

How to clear the contents of the buffer or make it possible to replace the buffer?

I found the solution, systematically through the palette DAQmx looking probable functions.

Simply insert a DAQmx controls Task.vi before the write.vi DAQmx, with set to cancel the Action. You can write new data to the buffer.

I knew there must be possible!

  • How to clear the output buffer, possibly resize and burn again, before you begin the task of output

    I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

    I have an output buffer that I want to be able to (re) write to without starting the task output.

    More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

    In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

    The generation is not yet started, and not enough space is available in the buffer.

    Set a larger buffer, or start the generation before writing data more than content in the buffer.
    Property: DAQmx_Write_RelativeTo
    Value: DAQmx_Val_CurrWritePos
    Property: DAQmx_Write_Offset
    Corresponding value: 0
    Property: DAQmx_Buf_Output_BufSize
    Corresponding value: 92

    In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

    DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

    Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
    Task name: _unnamedTask<0>

    State code:-200547
    function DAQmxWriteAnalogF64

    I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

    Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

    Is it possible to "remake" the writing of output before you begin the task?

    Thank you

    Michael

    Today I have no material practical to validate, but try unreserving task before writing the new buffer:

    DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

    With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

    I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

    I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

    The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

    The procedure allows for the header and the data to separate files if necessary. Just by specifying the file name "header" will put the header and the data in a single file.

  • How to replace the contents of the settings/passwords backup server / current browser bookmarks?

    Classic scenario: after the bookmark long manual organization Firefox Sync adds trash of its server to my laptop or tablet.

    Where can I find how to replace the content of the backup of the server by settings/passwords / current browser bookmarks? Stupid me, I put a new synchronization and lost this ability.

    It is not recommended to go back to the old version of Sync

    The old version is removed he'll stop being available soon, it takes getting used to using the new version.

    IIRC, it is actually possible to force synchronization of the old working with Fx29 & Fx30 using an old profile or preferences of piracy, but I don't think I should encourage users to try this, but it would be better than using an older version of Firefox which is really bad. In fact using an old outdated version of Firefox is so bad, that it is customary to recommend using a browser on alternative day of someone else instead.

    Firefox ESR is aimed at corporate users, definitely, at the moment, it will use the synchronization of the former. Who will update soon to use synchronization well again, and this time, I guess the synchronization of the former will probably totally frowned upon for example are not available at all.

    It is possible to use the feedback system to leave a short comment on Sync. I would recommend this making, but at least to make very many people of spirit comments that I doubt will have no effect.

    Hello

    My laptop's dvd - rom drive is old and broken, now that I have here an other dvd - rom drive, but I don't know how to remove the old dvd - rom without removing all parts of my laptop. Is there some service manuals how to replace the dvd - rom drive?

    Hello

    I m not 100% sure on the CD/DVD drive replacement on this laptop, but I assume that the procedure is very similar to other portable players.
    For the most part the ODD is secured with the screw at the bottom of the unit.
    You will need to remove this screw to get out and to swap the drive.

    But be careful and don t there if you have no experience!
    Moreover, not all readers are compatible and supported in reason parameters master/slave/c-salt. If you n t know which drives are compatible you should ask the ASP in your country for advice!

    Hello

    the optical drive of my Qosmio G 50 does not work properly, it reads only some movie-DVD, but unfortunately not videogameDVDs at all, so I can't install any games.
    The guarantee is also outdated. So I wanted to ask if it is possible to change the disk myself, if it is then how I had to do and if by the laptop would be in
    risk to get damaged?

    I would be very grateful for each tip and all the help guys can give me!

    Best regards
    a.z.

    Hello

    In various cases the ODD replacement is very delicate.

    If you wish, you can consult this forum category.
    Here you will find some videos how to replace the ODD on the different laptop models:
    http://forums.computers.Toshiba-Europe.com/Forums/Forum.jspa?forumid=115

    This is also a nice Youtube Channel which provides the instructions how to replace the ODD:
    http://www.YouTube.com/user/toshibaeuropesupport

    But the ODD laser lens may be dirty. In my case I could solve similar problem, cleaning the lens of the laser by using a cotton ball and alcohol tip.
    But make sure that this!

    How to replace the hard drive in this notebook?

    Hello

    If I remember well HDD is under the optical media drive. Optical media drive is fixed with a screw that you see above the player. Remove the screw and remove the drive from the Bay.

    HARD drive is fixed, I think, 4 screws (probably black). When the screws are removed you can use two fingers to remove the HDD from the connector plug. I hope you now know how to put the new HARD drive.

    Hello

    Well, the replacement of HARD disk drive is very easy on the Tecra S1.
    At the bottom of the unit, you will find a cover that protects the HARD drive Bay.
    A screw covers. Remove it.
    Then, it should be possible to remove the HARD drive.

    The replacement of the screen is another matter. It is not easy to remove it. In this case I recommend to contact Toshiba service in your country for details.

    Hello!

    AFAIK, you must remove the keyboard first, before you can replace the CD/DVD drive. Remove the screws on the lower side, and then you can push the disc if you have replaced the keyboard.

    I need to replace the hard drive on my Toshiba Equium.
    Can someone tell me the procedure? I changed it once before, and I remember having to press one of the function keys when I turned on the laptop with the new hard drive installed.
    Should I have the recovery disk when the laptop is turned on with the new hard drive installed?

    Thank you very much

    Tim.

    Hey,.

    You should take a look in your user manual. Sometimes you will find a detailed how instruction replace the HARD disk, but it according to your laptop model.

    If you swapped the HARD drive, you need to reinstall Windows. Therefore, you can take the Toshiba Recovery disk that will restore the initial setup in a few minutes with all the drivers and tools. You only have to boot from that drive and that s all! :)
