What would be the effect of the adjustment of the depth of DMA FIFO before every read?

I'm using a PXI-7813R FPGA board using a 3rd party API. I had a few problems during playback. I looked in their API (LabVIEW) code and realized that they were in DMA FIFO depth before each reading of the FIFO. This apparently does not cause a failure of catastrphic issues I have observed are only transitional in nature.

What kind of problems, if everything can these operations cause or will be ignored because the FIFO is already running?

Thank you...

mgerceker,

According to the help file , that should be OK to do even though I could see it being a problem if it is not set correctly before performing an operation. What kind of symptoms do you observe?

Greetings from Austin,

  • What would cause the "from address" info (FA). some emails, downloading the pop3 server, will be replaced by an 'f' 'common '?

    I get multiple research work emails (E/JS) and ecommerce. Some of them have a "Correct".

    For some reason, however, some of the emails from other sources, downloading the verizon pop3, E/JS server are indicated (wrongly) as having the FA SMJAM-JAM above. This situation prevents my email filters to plug these emails to their appropriate mail folder.

    Hello

    If I understand your problem, I think it may have to do with the addresses stored in your address book. Thunderbird can display the name of your address book instead of the name of the post office, where corresponds to the e-mail address.

    Check your address books to see if you have a bad entry for mail addresses get listed wrong.

    Also check under Tools-> Options-> advanced-> reading & display if you have checked the option to see show it only the names of the people in my address book. If you uncheck this option, the name and the address must be...

  • What would cause the mouse to scroll slowly on Web pages, but normally on text documents?

    I have a strange problem. I have a Logitech M305 mouse on another machine which is too slow scrolling on Web pages. I ordered a new mouse, but today I noticed the old mouse normally scroll in text documents, even though the text document is displayed in Firefox (such as the "subject: config" page).

    Normally, a page will scroll 3 lines for each click of the mouse wheel.
    On Web pages, it changes and it takes 3 clicks of the mouse wheel to get the page to scroll.

    It is troubling to move the mouse wheel and don't have anything happen until the third click.

    So the question is, what would make the mouse wheel behave differently on the Web pages and pages of text, and how can I solve this problem?

    BTW, this is a clean install of Windows 7 64-bit. I use the same exact type of install now on another machine with a mouse Logitech M510 and normally scrolls on all pages.

    OK, a final report on this issue. Yesterday, before installing the new mouse M325, I decided to uninstall the Logitech SetPoint software. I wanted a new installation of the software for the mouse to go with the new mouse.

    To my surprise, after the set point has been uninstalled the old mouse M305 scroll normally on pages of text and Web pages. It seems that something mysterious happened in the relationship between Firefox and the original installation of set point. Firefox made some adjustments or updates of its own regarding record just as it does for modules, I saw it happen a couple of times before. /shrug

    New mouse + set works perfectly with FireFox now and the old mouse M305 + setpoint is now works well with an old laptop XP Pro, at least as long as the button pop-up gimpy holds.

    Solution, in this case: uninstall the Logitech SetPoint mouse software, and then reinstall a new copy of it.

  • IM using Windows XP Profesional, can I upgrade to Windows 7 and what would be the cost?

    upgrade windows xp to windows 7

    IM using windows xp profesional can I upgrade to windows 7 and what would be the cost? what I have to put all my files on an external drive then uninstall windows xp then put in windows 7 then put back my files? is that how its done? Thank you.

    First the cost, you must know if your hardware can support Windows 7

    In General win 7 should a minimum og 1 gig of ram (for 32 bit) or 2 for 64-bit, and it needs a video card 256 MB or greater.

    If your less and can not be updated it may be best to start thinking about a new computer.

    If the above is ok there are various offers for win 8, but make sure you buy form a reliable site of Ms.  There are a lot of current scams.

    Good luck

  • What would prevent the AS3 to work in another exemplary work...

    Flash CS5.5? I upgraded from Flash 8 to CS5.5 recently. I used Flash strictly for entertainment until recently so have not really tinkered with AS3 at all. I tried a few tutorials and got '1120-errors of unrecognized property' and assume that there is something wrong with my code or my settings. After uninstalling, reinstalling, fitness and try several examples of files that I found online, it is clear that the just AS3 function is not compatible with my computer. Animation functions work perfectly, but I can't get the debugger to connect and HAVE # refuses to acknowledge all instances on the stage (and, Yes, I triple checked the publication settings are set to do so.) Is this unusual? What would prevent the AS3 to work when everything else is perfect?

    Which would normally result in AS3 to no function is poorly coded in AS3.  A 1120 error may result from certain things, so if you can describe a design simplified something you create which presents the erro and show the encoder, it might be easier to spot if there is a problem with the coding.

  • What would be the best type of table/chart to use?

    I'm testing a grid tie inverter. To the side of the grid, I need to provide a table/chart, which has:

    X axis: fixed, from 00:00 (midnight) and ending at 23:59

    Y axis: last watts measurment purchase / sale

    The table/graph must be emptied at midnight every night

    Measurements are performed at intervals of 10 seconds.

    This program will be running continuously for long periods of time (months in a row)

    I'm leaning towards a xy chart because the program can be started and stopped at any time and it's the only way I can think of to make sure that the line of measurnents correctly on the X axis.

    But I'm afraid that, since all XY graph is held in RAM (each line has its own displacement register) and measurment taken at intervals of 10 seconds.

    Who's going to add up quickly as the days go by finally out of memory and crash.

    Also I can not know how to delete the chart every day to avoid said memory leak.

    To make matters worse I need also a same table/chart for the release of load, batteries and solar panels.

    Here is my grid purchase sub - vi that I call after each action is taken and a message of State output and graphics for the main program.

    I would follow the advice of Lynn and manage each day of data as a separate table of data.  So do not grow a value of several days of data in a single table.  Move to another storage such as file system and clear the table and start again at midnight.

    But I think what they XY graph is the best display for all the reasons you listed as discontinuous data.

    Yes I'm still with the XY graph as we are still in the first part of the development lifecycle and it is possible that the device could be stopped and started several times during the day and I don't want the graphics to get all out of whack.

    But looking at my sub - vi, it occurred to me to treat it as an engine of the action or functional global and put an initialization state it I can call at midnight to clear the shift registers.

    For what is to come back a day or more, maybe it's something that I have work later. Daily data are saved locally in a separate file and using the XLR8 tool I'll roll seven daily files in a weekly Excel workbook for later analysis.

  • What would be the Windows 7 Installer download file name?

    A couple of years ago, I bought Windows 7 to upgrade a Vista laptop.  It is a download purchase that I had to create an installation DVD of.  Long story short, I never put Windows 7 on the laptop.  I did the installation DVD is not found I want to update now.  Somewhere on my computer laptop is that file that I downloaded to create the Windows Installer DVD... but what the hell would be the name of the file?  I have my product code recorded in the receipt of e-mail from the purchase of Windows, but of course the download link for the file is now expired.  I can order a backup drive now that the download link has expired, but I prefer to find the file and do not have to wait for a disk to be shipped.

    Any help to know which files am I looking for?  I'm guessing that maybe it's a zip file?  My hard drive is full and I have no idea what file name, I should be looking.

    Thanks for any help.
