• How can I navigate and play MP3 files from a USB stick using Labview 8.0?

  I am a tester to test the USB flash drives connected to the PC.

  I want to browse the file system & playback of audio files, files .jpeg etc in the USB. I have Labview 8.0. When I searched for some examples or screws which can detect the flash drive USB, cannot find a. So if you could point me in the right direction, I can find a solution to my problem.

  Thank you.

  You will probably find some specific examples for this.  A USB flash drive is mounted by the operating system and appears as a new memory storage device to all software on the PC, including LabVIEW.  You can certainly write a LabVIEW program to open the files on the key and the game/run their but I would create a VI who wrote the files on the stick then proofread and checked to find errors at the level of the ILO.  Don't forget that your operating system could do parity check under the hood that would make your test rather meaningless.

  BTW, memory test looking at pictures or listen to the MP3s would be useless of course.  A man cannot see or hear errors at the level of the ILO in a stream broadband.

• Not able to remove the USB stick while Labview is open

  For all the gurus.

  I'm using LabView 8.5 and made an Application that requires the user to download the data of the disc/USB. Then, when VI works user invited to select a. TXT from USB to download file. Here, the entire operation ends as desired. Only ONE PROBLEM I am facing is when download completed attempts to the user to 'remove the USB' where gives windows a warning saying USB is in use and cannot be deleted.

  This particular VI I use function of file dialog box to browse USB and let the user select a file. I even tried to use the function to open the file, but it gives same error.

  The only way I can pull out USB after the download is out of Labview which is not feasible for my application.

  is this a Bug in 8.5 or is there a different way to do it?

  Any help will be appreciated.

  Concerning

  You can call the Windows API SetCurrentDirectory function (see attachment), but if you follow the link you will see it warns about its use in multithreaded applications. I have no experience with it, so I can't comment.

• Do another counter for usb-6008 VI using Labview 8.5

  I want to create another counter for usb-6008 using Labview 8.5, it is necessary to calculate the two gears simultaneously.

  The best way to proceed is to use the meter.  The counter counts
  signals without having to interrupt the system or use the USB bus.
  When you ask the number of ticks that saw the meter, one
  request is thrown from the CPU to the USB line to the 6008, which then
  request counter "ticks how have you seen?  This number is
  returned on the USB bus, goes to the CPU and display on your
  screen.  Given that the DIO lines on the 6008 are software timed, it is
  no way to guarantee that the data back to the central unit is
  deterministic.  The conceptual difference between software-controlled
  DIO (that nondeterministically returns an entire stream) and a
  meter software-tick-application-controlled (which returns a unique number
  with the number of ticks) prevents us from using the DIO lines on the
  6008. the best way to count more edges is buying more 6008 s.
  Another possibility would be to buy a PCI card to counter such as
  the PCI-6602, who owns 8 counters. Most of the counters we offer in the
  USB form factor is 2 per device.

• How to program using Labview to an accelerometer

  Hello:

  I got an accelerometer which has digital I2C/SPI serial interface, so I bought a USB - I2C converter for data acquisition. I would like to know if I can use Labview to acquire data of com port and also program for the accelerometer to capture the data of the axis z. I have a box of white myDAQ NOR but SB. says that it is not an appropriate device to acquire before I2C/SPI signals. The datasheet of the accelerometer is in the accessory and the specification of the converter is this link: http://www.robot-electronics.co.uk/htm/usb_iss_tech.htm .

  I hope someone can solve the problem for me. It is best to use the software labview for me because most of my project work is based on that.

  Best regards

  The f

  Good and bad news.  You have an accelerometer that 'speaks' I2C or USB to I2C converter, so if you connect both of them, you can send 'orders' of your accelerometer easily of LabVIEW by using communication series live that's the good news.  The bad news is that it seems that you need to address your accelerometer using calls very low level, a work, I certainly don't want to face!  This crys on a 'pilot', a middle piece of equipment that does all the "hard work" to take a high level order ("Please tell me the acceleration") and he translates things your device includes (including the Setup program, records, calendar, packing and unpacking of the bits and bytes, etc.).

• What equipment I need another for the purposes of the on/off switch, adapt output voltage/current using labview program

  This is my first time to use labview, I want to use the program to control the DC power for the start/stop it or set the output to program automatically.

  Now I had the (supply) instrument, got a computer with labview. I know that I have to buy a GPIB cable, making a connection between the instrument and the computer. But I do not know what to buy? Cable GPIB or GPIB controller. Confused.

  Thank you

  A GPIB cable, by itself, will do nothing. You need a GPIB controller connected to your pc. With the NI USB-GPIB-HS controller, you can connect directly to a single instrument and no need for a separate cable. If you go with an internal controller to a pc (i.e. PCIe), you need a cable to connect the controller to the instrument.

  You can also check if the power supply has other options such as Ethernet or USB remote control.

• During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT.

  Hello

  During the installation of Windows 7 or 8.1 using a USB stick - get the message "cannot be installed, it is a GPT partition.

  I have 64 bit install discs for Win 7 and Win 8.1. These two install on my desktop in duel boot. I made a Flash DRIVE of each disk so I can install it more quickly.

  Problem: I get the cannot install because it is a GPT partition.

  Y at - there no way to make these 2 USB sticks work?

  Thank you, Brad

  Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

  Your computer does not have Microsoft's Downgrade rights and you must buy a copy of Windows 7 with a valid Microsoft COA and product key.

  The screenshots below is from a laptop HP 15 t-j100... options and the configuration on your computer screens may differ.

  You will need to DISABLE "Secure Boot" and ENABLE "Legacy Support" in the "Configuration of the BIOS start-up secure" on the settings page similar to what is shown below, until you try to install Windows 7.

  

  After you save the changes, the computer will ask you to confirm the changes... Accept the changes by typing the four digit code and press the ENTER"" key.

  

  If you install Windows 7 from a USB and see a message of "load a driver - a required CD/DVD drive device is missing", it's because as 'System Configuration' > 'Config USB3.0 in pre-start' is set to 'Enabled '. This should be set to 'Auto '.

  

  In addition, as the factory hard drive is partitioned as TPG, you must start using the internal CD/DVD UEFI or UEFI-Key/key USB to install Windows on a GPT-partitioned disk. Turn on or restart the computer and press "F9" or "ESC", then "F9" when prompted. Select the source of boot UEFI you use and you press "ENTER".

  

  I suggest using Windows 7 SP1 for the best installation experience. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please note that some computers may not recognize a valid active UEFI USB Flash drive if it is formatted in NTFS and may require only a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installeror WiNToBootic. I like Rufus, because it contains options for 'Plan of GPT partition for UEFI computer' and 'FAT32'.

  If you have any other questions, feel free to ask.

• Time real ADC/DAC for SMPS by using Labview and USB

  Hi all

  I asked the Sales Department of this same question, so here's a two-pronged approach:

  I am reserching a control algorithm for power switching, and so far, its performance simulations seem to be good.  Now, the goal is to implement the circuit from the experimental data.

  I've seen several NI USB DAQ boxes that seem to have the performance, I'm looking for (for example, the box USB-6211 a sampling rate and resolution I need).

  The control algorithm uses the following mathematical functions: add/sub/mult/div/exhibitor and derivative/integral.

  My question is this: is "strong enough" Labview take four-channel data 250Ksps, crunches the numbers in an equation and spits out the answer to an analogue on the channel, while time REAL?  I'm looking for a rate of analog output of ~ 100 kHz.

  Thank you for any suggestions you have!

  -Rick

  Hey,.

  So if you were trying just to perform an input or output, then the box USB-6211 would certainly be able to treat it as the machine clock could manage the inputs/outputs, no software. However, what you are wanting to do, basically a feedback system, he will have to avoid (at least to a USB device) because you need to be able to specify Active which is the output. So, for this reason alone and the fact that you want out of 100 kHz, this device and the USB devices in general will be not an option any what software you use, LabVIEW or otherwise. On another note, you want to make sounds more like live update, not in real time, which is more on the jitter. Bottom line, for these kinds of requirements, you might need to move to an FPGA card, something like the NI PCIe-7841R would work. It's more expensive, but for your needs, FPGA will be the only option and it comes down to the latency of the bus, but also the response time of software. With FPGA, as shown in the first scheme of the following document, you basically close your software through hardware loop.

• Programming computer laptop Wifi using Labview

  Hi dear all, can someone guide me how can I program my laptop computer Wifi module to send and receive data through Labview programming. What tools or drivers should I me take his Express or other screws are visible in Labview. If possible, some codes an example or link to that knowledge base. This will help me understand the concepts of programming Wifi. Thanks Zdzislaw qureshi

  Hi dear Dennis Knutson,

  I tried screws from TCP/IP and to understand. But how can we make our PC Access point using Labview? Are there any specific screw init or some additional toolkit required to do this. Actually I want to PC to become the hot spot to be connected. My app will then scan him in serach and then sign in to do some data send and receive actions. You have little help for me in Labview.

  For the wifi connection, I need to use the method of connectivity to Microsoft. How can I do this by Labview. I understood how to put IP LAN to detect in Labview only once I'm connected to the other PC via LAN wireless and wireless.

  Thank you & best regards

• Existing communication usb - hid in labview c code using

  Hello

  I want to write a simple temperature using labview recorder and an external hardware that communicates via usb - hid. The external hardware uses an ATMEL 90USB162 µC and probes DS18B20.

  Link to the material:

  http://www.diamex.de/dxshop/USB-temperatur-sensor-Tester-fuer-DS18B20

  The source of a simple command line tool is available (see attachment), which reads the value of the temperature of the connected sensors.

  Is it possible to include this c code in the labview application to simplify the communication?

  Thank you very much and best regards,

  Michael

  Hello

  I stopped using the existing code and replace by http://ahidlib.com/index.php/ahid-dll-and-labview. This works very well for me.

• Garmin Vector pedals USB ANT + in LabVIEW

  Hello

  I would like to read the data of the vector Garmin pedals in LabView. For this, I would use the Ant + Garmin USB Stick.

  I read a lot of similar topics in the Forum. But there was no real solution. Is there someone who works in the same topic or someone who already has a solution?

  I also read on a Toolbox ANT +, but I don't know where I can find.

  Any idea would be appreciated.

  Thank you
  -BR

  Hi BR,

  I have a solution for this problem, as I am the developer of the tool that you mention.

  Communication with the pedals of Garmin Vector 2 using an ANTUSB-m is possible, we tested here at the office.

  Unfortunately our website is currently undergoing a large redevelopment so it's not complete with all the information, but you can check it out here. There is still a little work to do on the site, so please have some patience when looking for things.

  You can also find details on the Web site if you have any questions.

  See you soon,.
