FPGA read/write does not not in cRIO-9073

Hello.

I'm stuck with a problem in the use of the FPGA Read/Write control please suggest a solution.

I use cRIO 9073 and I'm trying to place an order ON / OFF of GUI-> RT-> FPGA host. I use a shared variable of the network to transmit the control GUI form to host RT and I use read/write control to FPGA. I also put a Boolean flag in the FPGA VI to control if the control is transferred to the FPGA.

When I toggle the button in the GUI, I see the same change in the host of RT (shown as 16 probe in attachment 1). However the FPGA indicator (indicated as probe 19) remains the default false state. The FPGA VI is on attachment 2.

Thank you

Guilhem

Your FPGA only reads the control once before entering the loop.  If you want to read control permanently, you must put it inside the loop.

  • Reading TCP does not detect the network closed conncetion error (66)

    Hi dear all,

    Instead of LAN I use WIFI to connect PC and mobile. Read all communications and write operations are performing ok. But the only problem I am facing is that once I disconnect the network from a mobile phone connection my labview TCP read operation does not detect it and only timesout at the specified interval. Although for Bluetooth connection network if I disconnect mobile then BT read detects it as network conncetion closed in error by peer (66).

    Can someone help me on this.

    Thank you & best regards

    Zdzislaw qureshi

    Hi Zdzislaw,

    The behavior you're seeing is expected for TCP as the device will timeout while it is looking for the connection close the connection.  This Wikipedia article explains how TCP protocol works in relation to a handshaking procedure four lanes running in order to close a TCP connection.  I hope this helps!

  • County to return read VISA does not match number of bytes

    I encounter an error with a VISA reading.  I ask 8 bytes (in number of bytes), but get only 7 return (return number), which causes errors in my code downstream.  Curiously, the VISA Read block does not return an error.  Any ideas on how to debug this?

    Data sheet:

    LabVIEW RT 8.2

    VISA 4.3

    Series OR 3.3.0

    PXI-8431/4

    Parameters: 1843200 Baud, 8N1.

    Is VISA reading set to put an end to the reception of a termination character?  I think that it does not have the stop in the output string character, which could make your short back counter.

  • When I try to burn a music disc player is registered as a DATA reader and does not allow me to copy music files that I can play on an external source

    I have computer aGateway running Vista Home Edition and something happened with WIndows Media Player.   I have the DVD/RW internal drive and external DVD/RW as a player.  I use them mainly to copy music files and it has always worked fine until yesterday.

    When I try to burn a music disc, the player is registered as a DATA reader and does not allow me to copy music files that I can play on an external source (such as the CD or car drive).  Worked fine Saturday and had burned discs Saturday night recognizes the two drives as data drives.

    Is it something that needs to be reset or changed?

    In WMP, please click the button burn up and make sure that the Audio CD is selected. Then try burning the CD again, they now play on a standalone CD player too.

    I closed out of all tabs, went to "safari" in the top of the page, clicked on close safari.  I clicked on Go, and then click applications, then I found adobe down and clicked on it.  then he gave me a place to click on accept.  I hope it works!

    My (certainly old and slow) system made too the first time I opened 11 player, but he "thawed" after fifteen seconds, (an eternity in computing time, I know, but it has finally opened completely) what you see to the right is the "Tools" palette during initialization. That's exactly where mine would freeze at startup. Once he finally opened fully, I clicked on the "Tools" link at the top to close the Panel, and I opened and seen a document in this way and then closed reader. Now when I open the drive, the tool palette is not initialize and it opens immediately.

    Restart and prior to open what any else, open the drive. When you open it, DO NOT try to do anything with it until it fully opens, do not click on anything that it either, do not try to switch to another app give it time to open up completely and then click the tools link to close. Then open and view a document and close it. Close the player and reopen it. the tools Panel should stay closed and reader should open completely immediately.

  • Frequency of calls to control for the FPGA read/write

    Hello

    I use a cRIO-9076 with a module NI 9476 DO spend some faucets. It is sometimes necessary for faucets with a pulse time down to a few ms of impulse.

    The FPGA VI Gets the power tap queries, executes a logic of security, and routes the numerical results for the exits. It gets applications power of the VI on RT target that uses the function ' Read/write FPGA control' interaction programming of the FPGA VI front. The loop on the RT runs with 1 kHz, no iteration is missed. That means, it should be possible to switch the valves with a resolution of 1 ms.

    What I see on an oscilloscope, is that the output digital are high for multiples of 50 ms, the system does not reach the valve for example 80 ms pulse or pulses shorter than Ms. 50 is a kind of limitation for calls of "FPGA read/write control"? I tried both options for arbitration, but it does not help.

    The best knowledge of the limiting cRIO/module/features or ideas? Thank you in advance.

  • HP DVD Writer does not read or write DVD, but only the CD

    My HP DVD 1135t burner does not read or write DVD but only the CD. What is the problem? Please help me.

    CD/DVD players use different lasers for reading/writing DVD from the CD.  All indications would point to your laser DVD as having failed.  You could try to remove your drive and install it in another computer to see if the problem follows your player or your computer, but my bet is that the drive must be replaced.

    Hello

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are
    the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and
    the correct registry entries for your car.

    Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
    as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
    the parameters.

  • TECRA M9 card reader still does not not with Vista SP1

    Why Toshiba didn't supply of integrated drivers for the card reader M series for people who do not want to run the Toshiba version recompiled Vista, which allocate Inc. of the unwanted software like Norton to slow down the Vista system!

    Im running a clean install retail Vista x 86 with updates, but 1-2-4 & 8gig sd cards will not work!
    in Device Manager it says "the device cannot start code 10".

    IM also beta SP1 which will detect the SD card, however cannot you read/write on the SD card.
    An update of the factory of the SD card reader Vista is whats needed!

    Hello, Robert

    At first, I must say that you are completely mistaken.

    The first Toshiba does not force someone to use the recovery image only. You can install your own version of Vista at any time. I also installed Vista Ultimate on my laptop. I also installed the just necessary drivers, download page of tools and utilities following the Instructions of facilities of Toshiba document. I hope just do you the same thing.

    As you wrote that you are on the tests of SP1. I also believe that Toshiba is also on the tests because SP1 is still beta version and so far not implemented the recovery image. Up until Toshiba offers no support for SP1. I can imagine different things will not work properly and Toshiba that will probably correct with the new drivers for the problematic hardware components.

    In the end, I can say: you can use your own OS installation like me and thousands of other owners of Toshiba laptop.
