Can't see the terminal emulator port after all control with VISA

Hello

I created a LabVIEW VI to control cycle to PWM channels on a microcontroller FRDM KE02Z reports. The microcontroller, programmed in CodeWarrior, is set up to receive an an input of the terminal string and break it in two parts (the channel name and ratio), which are then applied to the PWM. The code works and I tested with the 2.9 Termite and a Logic Analyzer before ordering through LabVIEW. The problem I had, though, is that I have to completely close LabVIEW to see the port on the new Termite and vice versa.

Previously, I had problems with VI after I something else in it, even a VI almost identical, more open as he was using the same port. I get errors and be unable to get my VI to work again unless I restarted LabVIEW. I was able to fix by adding a VISA flush the IO buffer according to a discussion earlier (http://forums.ni.com/t5/LabVIEW/Timing-issues-with-Serial-Read-Write-can-t-achieve-terminal/m-p/2636... once the configuration of the Port series and at least now I can jump between the screws I am still unable to see the port jumps between LabVIEW and termite, unless I close one;) Close VISA and the closure of the VI are not enough, I must close LabVIEW himself. Is it possible to achieve only within the VI? For example using a VISA or VISA clear Flush at the end (after closing VISA)? If Yes, what is the difference/preference between them?

As I mentioned previously, the VI is functional, but I would like to know what is happening for future considerations. Would appreciate any advice.

Hope to hear from you,
Yusif Nurizade

You have not wired resource VISA through the stop event name so it doesn't close anything.

  • UCS C420M3 server with VIC 1225, can't see the ethernet LOM ports

    Hi Guyz,

    We have C420M3 server with VIC 1225 connected on PCIe slot, with fabric Interconnet.

    After you have installed the OS & drivers, vNIC created the VIC 1225 by the service profile appear, but 4 gig on server LOM ports do not appear.

    Any idea. ?

    Thank you

    If you incorporate your rack server to UCSM, you will be able to use the LOM ONLY ports for traffic of Mgmt, when you join the server mode to 'Dual Wire'.

    It is useless (unless you have one for a special reason, I do not intend at this very moment) to use ports LOM, once you entered the server, precisely because of the 1225 VIC is not a regular NIC card or a regular HBA, it is indeed a CNA (Converged Network Adapter), which essentially allows you to do in a map , what you would do with two (which means "what you would do with a NETWORK card and HBA separated')

    When you have a VIC card, you actually have the ability to create up to 256 virtual interfaces (this is the capacity of the equipment, always limited by the operating system, please keep this in mind), this is the reason why, after the server is integrated, entirely rely on the interfaces in the Service profile instead of the physical interfaces.

    Find more info here:

    http://www.Cisco.com/c/en/us/products/interfaces-modules/unified-computi...

    You have a specific reason to use the LOM ports rather than create 2 additional virtual interfaces in Server Service profile?

  • See the playback bar only after all the captions display?

    I'm trying to understand how I want my users to navigate, and thanks to the response of lilybiri on conditional actions, I am able to make the play bar jump up if users hit different buttons - thank you again.

    But here's what I don't know now.  I have another slide in which I want to have all the text and captions arrive on schedule (which follows the narration), but then not the pop play bar until all these were posted.

    In others, I understand the conditional action that will show the playback bar, but here I have nothing to attach a conditional action too.  I just want the PlayBar appears at the end of say 30 seconds, and let the user decide when they progress, but don't let them move forward before the entire displayed page.

    Note: The slide automatically suspended because I have a button that appears and allows them to view additional content, but I don't want that it is a mandatory button before seeing the play bar (if it is required, then I could use it as the action of condtional to shw the PlayBar)

    You need an event to trigger a tip action, and calendar is not an event.

    Why not to create another identical slide and have the playhead to move to this slide, after the first slide (with a chronology of 30secs) is over?

  • Can't see the iSCSI data warehouses after reboot

    I have 2 ESX 3.5.0 u3 hosts running on Dell PowerEdge 2950 servers and connect to a Dell PowerVault MD3000i. Recently, I upgraded the MD3000i gen.2 firmware, and after the upgrade, one of the MD3000i controllers began to experience extremely slow (3-4 MB/s) write to its LUNS assigned speed. Dell support reviewed my setup and said I have a configuration problem - all 4 of the MD3000i ports are on the same subnet, while according to them, they should be divided into two subnets. I have interruption scheduled for this Saturday, close all virtual machines, added an additional VMkernel port and a service console for the new subnet on each host, removed addresses for two of the ports of discovery dynamic and restarted the two hosts. When they restarted, I changed the IP address on a single port on each controller. The servers came, restored 4-port iSCSI sessions and can see two LUNS defined on the MD3000i, but cannot see data warehouses - it's like they went, and LUN are naked. Creating new data warehouse will wipe away their own, and while I have current backups, I would rather jump restore all this from scratch. Is there anything that can be done here?

    -Very well, could be a problem of will:

  • Wireless dead after reinstalling Windows. Device Manager can't see the map

    Hello

    I have a laptop model Lenovo 3000 N200 14W 0687.  It was teeming with virus so I wiped the hard drive and installed Windows XP Home Edition from scratch.  Now Device Manager can't see the wireless adapter and Wireless does not work.  I tried to download and install the Wireless driver on the Lenovo site (I don't have a disc of relocation); but I got errors.  Anyone know what could cause this and a fix?

    If you are interested, here are the details of what happened when I tried to download and install the drivers:

    Device Manager gives me the adapters three following network:
    Network adapter 1394
    Broadcom NetLink (TM) Fast Ethernet
    MAC bridge Miniport

    None of which resemble wireless cards. So I used the link http://consumersupport.lenovo.com/ot/en/DriversDownLoads/Drivers.htmlto try out. Enter my serial number L3X3516 took me to a support page client lenovo that says

    Total 13 drivers need to be repaired/upgraded, 9 drivers in need of repair, please click the "Download" button to begin to repair

    One of them was this:

    Intel (r) PRO/Wireless 3945ABG Network Connection

    I downloaded it and it says: 'the contents of this file cannot be unpacked. the executable file that you are trying to run has been damaged. You can get another copy of the file, verify its integrity, and then try again"

    So I used google to find this site:

    http://www.getpcmemory.com/drivers/download-Lenovo-3000-N200-type-0769-notebook-Windows-XP-Vista-DRI...

    who told me that my computer is a Lenovo 3000 n200 Type 0687.

    Using google once again, I found this page:

    http://www-307.IBM.com/PC/support/site.WSS/document.do?lndocid=MIGR-68011

    which was another version of the driver. So I downloaded and unpacked it. I then took a glance at the .txt guide provided with the driver. It is said:

    1. Start Windows XP and log on with administrative privileges.
    
    2. Double-click the driver package to extract it to your hard drive.
    
       The default location is C:\SWTOOLS\DRIVERS\WLLANINT
    
    3. Click Start, then click Run...
    
    4. Specify SETUP.EXE with the full path name where you extracted the
    
       package in step 2, and click OK.
    
       Example: C:\SWTOOLS\DRIVERS\WLLANINT\SETUP.EXE
    
    5. Follow the instructions on the screen to complete the installation.
    
    Unfortunately, there is no setup.exe file in the folder so this has failed.
    
    Regards,
