• What type of support for labview usb protocols?

  Hello guys I want to connect a device to your pc via a usb port and I want to use labview to analyze the data.

  But first of all, I would like to know what usb protocols support for labview.

  USB, USB CDC and other TMC?

  I ve read labview recognizes a raw device to the usb, but what is? Is it VI to read and send data, or I have to do? If these VI exists, they do the handshake? flow control?

  Thank you.

  Please read the chips and have a look at the USB specification (it is linked to in the nuggets).

  TMC, CDC, MAss Storage are all built on the basic USB protocols.

  LabVIEW has no built-in support for one of these classes of devices except Test and measurement.

• 1208fs for labview 10 usb connection problems

  Hello
  I'm relatively new to Labview and just improved labview 10. I used 6.1 before and had no problems using my mcc Board of 1208fs USB to run experiences before. I tried to connect even to labview 10 on my new computer, and the only thing that will connect to the instacal is. Ive plugged throu instacal, but is not visible in the list of I/O that selects the channel to use. Any help would be appreciated.

  By the way, my os is windows xp

  Andrew,

  MCC daq devices have a different set of drivers for LabVIEW 8.2.1 LV versions and newer.  See http://www.mccdaq.com/daq-software/universal-library-extensions-lv.aspx this is ULx.

  I have one of the devices USB-1208 and discovered very recently this issue when I wanted to use it in a LV 8.5 application I wrote.  The new driver is actually nicer and DAQmx drivers a little resembles the way you use them.  While the former pilots of the Universal Library for older versions of LabVIEW looked like using traditional DAQ hardware drivers of OR.

  I can see the MCC card detected in the software InstalCal of MCC supported. I installed the latest version of the CMC the CMC site software.

  As far as I know, you will not be able to see physical computer as in MAX.

  From the file of help from MAX: "Measurement & Automation explore (MAX) allows to access your National
  Instruments of devices and systems. "that is material MCC is not a feature of National Instruments.

  Why not stick with the InstaCal software and the MCC screws provided?

• Whith USB Device error: "Windows cannot verify the digital signature for the drivers required for this device...". (Code 52) »

  Original title: open usb drivers problem

  My Dell laptop stops working with USB storage drivers. The removable driver icon is displayed in the devices window and printers with a yellow triangle around!
  I've tried different USB drivers and the problem persists. I tried troubleshooting, and it does not help.
  In the Properties window, I get the following message:

  "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52) »

  I don't remember making any hardware/software changes and do not know how to solve the problem.

  You are welcome.

  Something seems not quite right so contact the store can be a good idea.

  Back to the initial problem as I understand it, is that when you insert an external drive, you get the error 'code 52?

• How can I read/write from/to a USB in LabVIEW

  I read through a number of tutorials and help information, but I can't seem to find a way to do it.

  I created a driver for LabVIEW to recognize the USB and I can find it using the 'VISA Interactive Control', but which is as far as I can get.

  How can I simply write a small file on the USB key and read the same file back? I'm just trying to make the verification tests.

  (via LV2009)

  Thank you

  I don't understand why you're messing around with VISA. When a USB drive is connected to a pc, normal windows driver will be appear as an extra disk and you can write and read it with the regular file IO functions. He has held several positions on the detection of the indicator of new road.

• E/s digital USB-6008 changes when the system starts

  I was intending to use the USB-6008 housing in a critical application in which the digital I/o lines are used to trigger relays.  The relay should activate when I ask them programmatically.  Otherwise, they must remain open.  The problem is that during a reboot of the operating system, the e/s digital USB-6008 go up and down several times - opening and closing my relay.  It is not acceptable for my application.

  Is it possible to prevent the lines to reach logical high except if ordered to do so?

  There is no way to set the startup on the 6008 States.

  As the system USB boot devices and turns on power to the computer and off the power to the USB ports, on the DIO lines go up and down several times.

  You will need to put a logic of material extra, just after data acquisition to ensure that potentially dangerous output combinations cannot affect the relay and the elements they control.

• can I create a DLL file for labview that has DLL library with inside?

  Hello everyone,

  I am developing an application for the cards PCI devicenet in labview (beginner to labview) environment.  Is there a DLL file for the PCI card from the provider. But it's too complicated for a beginner to call each function in the DLL of labview. Therefore, I'm trying to re - use a VC ++ program (working properly) that calls some sellers DLL library functions.    To do this, I created the DLL file which includes all headers and libraries the provider DLL, as indicated in the attached figure. But I couln can't see the effect on the device. is it possible to create a DLL file for labview that has DLL library with inside? If this is not the case, how can I implement the program shown in figure?

  I would like to wish a huge as to advance.

  It is not something I have a lot of experience in so I don't know all the details of the restrictions or requirements etc - but it is certainly possible to create wrappers for the dll and then use them in LabVIEW - this is sometimes necessary to convert some native types/data structures in C/C++ into something that you can switch to your other DLL LabVIEW.

• Why the basis of NOR-DAQmx for LabVIEW options are grayed out using a custom installation (with Action: Skip)?

  I try to install NOR-DAQmx Base 3.7.0 LabVIEW 2013 (LV is installed). When I try to install Standard, it does not settle for LabVIEW (only the tools common and C and USB), but gives a successful installation message.

  

  When I try to custom installation, all the "...". for LabVIEW 20XX"options are unchecked, dimmed and Action says 'Skip '.

  

  I try this on a 2011 MacBook Air 11 '' running OS 10.9. LabVIEW works very well.

  Thanks for your suggestions.

• 610n seeing key USB - drive 1 TB Western Digital USB router plugged

  I just bought a router 610N and everything works with wireless PC and internet connections, etc. I upgraded the firmware to 1.00.03 B15 hoping that would solve my problem, but did not. I hooked a 1 TB Western Digital USB to the USB port on the router. Small bright for the USB light on the router, however, in the storage of Setup tab web to the router it shows no available drive. How can I set up and access the USB? I want to be able to share with all readers the PC connect to the router. Help, please. Thanks in advance.

  I called linksys support. They had updated me the firmware to the latest firmware version 2.0 even if my hardware version 1.0 and everything works like a charm now. Later, I'll update the firmware with version 2.0. They said the only difference between the hardware version 1.0 and 2.0 is the power switch - 1.0 is not a power switch top and 2.0 - should unplug the router for ver 1.0 to be put off.

• Windows cannot verify the digital signature for the drivers required for this device

  I get this error from a specialized device that uses a usb/network card connection built-in.  It is with windows 7 Home premium.  Now I know that the source of the driver.  It is the latest driver and labeled for use with Vista.  I need to override this security check, so I can use this equipment.  It is an integral part with me a living. It is likely absolutrly nothing wrong with the driver.  I downloaded from many sites without modification.  This equipment worked well under Vista.

  Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)

  I found the answer by looking for other sites, it's probably here somewhere as well.  Restart the computer.  During restart, press "F8".  Select Disable Driver Signature Enforcement in the start menu.  This fixed the problem of driver in my case.
