• labVIEW Arduino interface

  Hey,.

  I've interfaced arduino and labVIEW 2012. I run the LIFA_Base file in the window of the arduino and then close it and run my program in labVIEW. whenever I have stop the labVIEW program and the next time I run the program in labVIEW, that it's not until I reupload the LIFA firmware. So, what is the solution such that I did not download the LIFA firmware every time.

  Good quick response.

  Rich.

  Rich,

  I think your code is good enough to read the data in series.

  Please check the attached sketch (which is the same as what you have downloaded to the arduino) also I join the LabVIEW VI to read data series.

  Please make sure that the COM port that you use for arduino should be the same for LabVIEW.

  Also close to the arduino.exe (the software through which you have downloaded the sketch.

  Then, run the supplied LabVIEW VI.

  Better use of the arduino with LabVIEW, you can find step by step here information

• you want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. A

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

• LabVIEW for control unlimited, a camera and a light meter (Minolta T - 10A)

  Hello world

  I'm totally new in the use of data acquisition software, but I found out, I use LabView for continuous measures (intervals of 15 min for 1 month or maybe more), the thing is that I need to get pictures simoultanously (Canon camera EOS) and illumination (in lux) device: Minolta T-10 a vision series T-10MA. My question is what software LabVIEW do I need to buy (or my institution actually) in order to get this. I look at the options of LabVIEW software and cannot understand what is needed. Subsequently, I guess that I need controllers for each of the devices (minolta and canon). Can you please tell me if this is possible and how to do it. I would really appreciate it.

  Steph.

  The following items are required: LabVIEW full, all drivers of devices (including DAQmx and pilots of the Vision) and the Acquisition of Vision software package.

  The Minolta luxometer has a connector for a PC and some communication software (which I did not inspect) which, I suppose, would allow you to take readings.  There is a comment about current if the USB cable is connected - I don't check if there is a power connector on the luxometer (since you will need to leave it plugged in for a month, the same problem with the camera).  As far as the camera is concerned, I don't know if it is controlled from a PC - my experience has been with (the size of 640 x 480 pixels) video cameras, which are probably controlled by LabVIEW.

  As for simultaneous readings, it is something that LabVIEW did pretty well.  I advise you to consult a professional if it's anything other than a school project, maybe even hire someone to work a few week of.

• LabVIEW for linux (Ubuntu 64-bit)

  University of Helsinki uses a centralized managed linux installation on all linux workstations.  The distribution is based on Ubuntu 9.10, and it is considering moving to 10.04 LTS.  Almost all of the facilities are 64-bit, only a few old machines (> 5 years of age) are still using 32-bit installation.

  In the Physics Department, there are about 500 machines and about 30% of those who are linux workstations.  We strive to get LabVIEW for Linux installed on our desktop, then run under Ubuntu 64-bit.

  1 problem (not a problem): For some strange reason, the installation media does not CD/DVD use normal files (iso9660) system, but the media is formatted with the file system "Mac OS X HDF +".  It works under linux, of course, but has been a source of mild confusion.  It would be wise to change the normal file system to the next version.

  2nd problem: The installation under Ubuntu does not work.  Namely:

  First I mount the media with the "mount-t hfsplus/dev/sr0/media/cdrom0" and try running the installation script
  CD/media/cdrom0/Linux/labview-2009
  sudo knew
  . / INSTALL

  Installation is not going smoothly.  According to the error message, the script is not found the library libbz2:

  / Media/cdrom0/Linux/LabVIEW-2009/bin/rpmq: error while loading shared libraries: libbz2.so.1: cannot open shared object file: no such file or directory

  However, the library is in standard place:
  $ ls/lib/libbz2 *.
  /lib/libbz2.so.1 /lib/libbz2.so.1.0 /lib/libbz2.so.1.0.4

  I know, "support of the distribution" list only include Mandriva, RedHat, and SUSE.  The version of LabVIEW is the latest version of the fall of 2009.  Does anyone have any ideas what to try next?

  see you soon,
  Pekko

• Which is better: Labview for everyone or learning with Labview?

  I am a novice user of Labview, but I went through essentially through the 6 hours on Web site tutorial for NOR and that I'm currently going through the massive list of examples included in Labview. I heard the two Labview for everyone and learning with Labview recommended texts. I'd rather pay one, unless I really should bring both eventually. Thoughts and opinions by comparing the two?

  The two books are very good.  If your just starting, go to Amazon, buy a copy used learning with LabView 8 or 9.  I got mine for $18 shipped.  You can download all the vi.  Can also buy LabView for everyone $61.  LabView for everyone covers almost everything on LabView and brings you to some more advanced things, but learning with LabView has been better for basic stuff.

• How programmate a waveform arbitrary in LabView for an AFG3102C?

  I am trying to send a LASER pulse which is controlled by the CH1 of my signal generator. This is typically a 1us pulse, followed by a variable period (of 300ns to 10us) and then another pulse LASER to 1us.

  I don't see how I could program in LabView without using another program (i.e. Visual Basic).

  I'm using LabView 10.

  LabVIEW is capable uber; including in the instrument control.

  There is an instrument driver for the AFG3102 provided on the Web site of NOR. Download you and use the library of Virtual Instruments (VIs) comes with the LabVIEW environment. There are tutorials on how to do it. You can see the libraries supports GPIB/USB/Ethernet, so you must use one of these protocols to connect to your device, and then configure it within your own LabVIEW VI; You can reference the file 'Plug and Play' on the page driver instruments first to see how the device is controlled in LabVIEW for a sample application.

• Cannot control the color sensor in LabView for Mindstorms

  Hello!  New here.

  I'm currently boning on LabView via 'LabView for Lego Mindstorms' for a possible job in the near future, and I encountered a problem from the beginning.

  I am programming my brick Lego of LabView to simply activate the color sensor which is quite easy: I'm building a while loop and inside I have a block of color sensor attached to a block of text that displays the light intensity of the probe in the text on the brick.  I compile and run the detector turns on and I can read the intensity constantly updated on the brick.  This part works fine.  I would now like to control the light sensor (that doubles as a light source with color LEDs) on the front of the LV Panel.  The book I'm using (LabView for Lego Minstorms) says I should block sensor on the entry "generate light' do right click and choose"Create--> Control"in the menu that appears.  A Boolean command button should appear connected to the sensor block in the block Panel and a push button should appear in the front panel.  This is not what is happening.  Here, the two things are different.

  (1) I have no port "generate light" click on right-click.  This is probably using a version more day of Mindstorms that uses of the book.  It's a matter of book/Mindstorms, which probably cannot be resolved here but I hope that the next issue of problems will make it irrelevant.

  (2) I right click and create the control, but rather than create a Boolean command button as the book predicts, it creates an icon "BrickReference.lvclass".  He connects very well with the light sensor and a corresponding block is created in the front panel, but it is a paper weight that I can tell.  I can't do anything with it.  There are no buttons to push, no slider, button, button radio etc and I can't seem to change into something that somehow work.  I have delete and don't create a no kidding Boolean button from the library, but it does not connect to the photoelectric cell and so I can not compile.  So now, I'm a little stuck.

  I searched "Reference of the brick" online in the context of LabView class and have found little or nothing that talks about its definition or how I can use it to control the light via the front panel sensor.  Help with the software section is not much help, and yet I'm sure there must be a way to control a simple Lego light sensor of the façade for debugging purposes and others.

  If you know what I'm doing wrong or if you know a finish around this issue that will allow me to control a Mindstorms brick from the front in this way, please let me know.

  Thank you!
