Elvis board

Hi, I am using labview and an Elvis board, and my task is to use a push switch on labview to turn on an LED light on the right hand side of the Elvis board. I have the switch on my front panel/block diagram, but have no idea how to wire it so that when I run the VI, I can control the LED's and turn them on and off when I want to. Does anyone know how I can do this?
Thanks.

Hi Nizza52,
Thank-you for your post and welcome to the NI forums.
Looking at the schematic of the Elvis board there are a number of configurable I/O pins called LED 0..7. These pins are directly connected to the LED Array that I assume you are trying to light up.
You should therefore be looking to write the on/off signal to one of the Digital Out lines using the "NI ELVISmx Digital Writer" express VI. This can be found under Functions Palette -> Measurement I/O -> ELVISmx. You can use the express VI to configure what signals you wish to send to what DIO pin. A high signal should obviously be written to the I/O pin which corresponds to the LED you wish to light up.
You can use context help (Ctrl + h) within LabVIEW to find out more about the functions you are using if you require. Let me know if you need any further help!

  • Variable output on ELVIS board

    Hi,
    I need a little help from anyone experienced with ELVIS board. I’m new to LabView, and specially to DAQ tools.
    I have vi that is designed to drive small DC motor using ELVIS board and Variable output.
    it’s capable of driving small DC and changing speed of rotation, but I need to drive this motor in both directions.
    Does anyone know is there any way to achieve this using Variable output (to change it’s polarization), or any other way to do this on ELVIS board.
    Thanks in advance.

    This propose with 4 transistors (H-Bridge) is good but then I can't use Variable supply to drive transistors, as I need two outputs which should be switchable. In other words they should be able to change polarity so oposite transistors can conduct. I could use digital outputs, drive them with PWM, but it's too complicated for me.
    The best way maby would be to generate two PWM's (in quadrature) using Analog outputs (arbitary waveform generator) and H-bridge, but I don't know how to accomplish this 

  • Will the ELVIS board work with LabVIEW 2010 Student Edition?

    I recently acquired a traditional ELVIS board (with the PCI DAQ board). So far I've only installed the evaluation for LabVIEW 2010 (x64), and when I attempt to install the ELVIS Traditional 3.0.5 software I get the following message: "This installer requires LabVIEW 8.5 Full Development system or later to be present on this computer. LabVIEW Base Development System in any version of LabVIEW is not supported. Please install LabVIEW and then run the NI ELVIS installer again."
    I am eligible to purchase a student license for LabVIEW 2010 and would like to know if the ELVIS Traditional 3.0.5 software will install after I've acquired a student license.
    I am running windows 7 (x64) with an evaluation version of LabVIEW 2010 (x64). 
    Solved!

    Perhaps I spoke too soon. I purchased a student license for LabVIEW 2010 and am still receiving the same error. I've provided screenshots of my license and the message from the ELVIS Traditional 3.0.5 installer.

    Hi Ukairo - 
    Both hardware products can be used to demonstrate the control of temperature.  Can you provide more information on the course to help us provide the best recommendation?
    - Mark
    1.  Do you have a list of the labs used in this course?
    2.  What type of temperature sensors are you planning to use for the demonstration?
    3.  Do you have a syllabus for the course you can share?

  • How Multisim, ELVIS 2+ Board, and Labview All Connect

    My school recently obtained some ELVIS 2+ boards and I have been tasked with figuring out exactly what they can do and how we can incorporate them into the curriculum as part of my work study.  Now I have all the basics down for building a circuit on the ELVIS, getting measurements and controlling inputs on the computer etc.  I would like to delve deeper into what the full potential of this device is by integrating it with multisim and Labview.  My question is, is it possible to construct a circuit (or partial circuit) in multisim and then send the output of said circuit to the ELVIS board where it could feed into an actual circuit.  For example, could I build a voltage supply virtually in multisim, and output the voltage to a specific pin on the ELVIS board where I could wire it into my built circuit?  Along the same lines, could I build a circuit on the board and send the output of the circuit to a program in Labview?  Is this board capable for such things or is its connections to labview and multisim just used as a comparison tool for real life readings and simulated readings?  What is the full potential of this board?

    Hello,
    Glad to hear about you work with NI ELVIS. The integration between ELVIS and Multisim is limited to running circuit simulations and then comparing results with the real circuit, in other words, you can compare simulated vs real measurements; this is a great approach to circuits education. 
    Now, if you want to have more control of the inputs/outputs available on NI ELVIS, then LabVIEW is the perfect fit. In LabVIEW you can use the NI ELVISmx Express VIs to configure settings for all the instruments. Furthermore, NI ELVIS is supported by the NI-DAQmx driver, therefore you can use the NI-DAQmx functions to acquire signals from the analog inputs, generate signals in the analog outputs, access the digital I/O and program general counter/timing functionality.
    Visit the NI ELVIS & NI myDAQ Instruments and Applications community to learn more about the integration between ELVIS and LabVIEW; in this page you will find some ready-to-use applications.
    Hope this helps!

  • Isit possible to have two Ni elvis writer in one Vi using the same device and using 2 different NI elvis?

    Hi is it possible to have two writer in one Vi with one elvis  and also use two different elvis on one Vi? I hope someone can or know the answer.

    If memory serves me correctly, an NI Elvis board connects to a PCI card in a PC if you want 2 Elvis boards then you will need 2 PCI cards.

  • How to generate 3 phase sine wave to output on ELVIS

    Hi .I need to make a star or delta connected circuit on ELVIS board.2 make this circuit I need 3 wave generator( with 120 phase shift) and one common ground

    Now I can generate 2 continuis sine wave in labview and output them on the analog outputs of ELVIS.Ao-0 and A0-1
    but I dont know what to do for the third signal.the elvis board just has 2 analouge output and when I use  Ao-0 and A0-1 I cant use ELVIS function generator after that.so would u please help me on this problem.how can I output 3 contious sine wave in Elvis.I have attached my VI to this post

  • RPM measurement using NI ELVIS? help me out

    i want to measure RPM from two different sources simultaneously using NI ELVIS and i am using an hall effect sensor, how to do it?
    info:
    my hall effect sensor has 3 pins Vcc, GND, out
    i connected the Vcc, GND to ELVIS board itself and the OUT pin to CTR0- SOURCE pin (is this connection correct? i left CTR0-GATE and CTR0-OUT free)
    from one of the website i found that i need to use frequency counter
    so i went to NI-DAQmx->create task->acquire signal->counter input->frequency (i did a test run, nothing was working)
    then i did edge count NI-DAQmx->create task->acquire signal->counter input->edge count, here i could see the up counting every time i passed a ferrous material in front the sensor.

    I'll pass this to you to see if it helps

  • Liquid Level Sensor, NI ELVIS II+ and Labview

    Hi,
    I am currently using a Liquid level sensor, from what i can affirm is that it has two states, Float down = Contact closed; Float over = Contact open. I am wondering how should i connect it on the elvis board and display the two states on labview.
    Sensor in question

    Solved!
    Go to Solution.

    Hi Foster,
    Since the output should just be either 2 states; contact close or contact open, I believe you can connect the sensor to Elvis board through the Digital port. 
    But first you need to check what is the voltage been generated when it is floating down and floating over as the Digital port just recognize the LOW (off) and HIGH (on) states when it is within range 0V - 0.8V and 2.2V - 5V respectively.

    Launch LabVIEW, then run Help >> Example Finder and search for Elvis.  Many examples should be installed.  Also go to your palette on the block diagram and search for Elvis and you'll find the palette with all the function calls.
    If you are new to LabVIEW you may want some free training.

    (I moved this post from the NI-ELVIS board)

    Do you have a sample file we can take a look at?
    Remember that in a ELVIS Schematic you have to connect power supply and ground pins...  if you look at the schematic (not the 3D breadboard) to the lower left corner you will see a connector that says GND and +5V (among other ones), if you have those connected in the schematic... when you transfer to 3D breadboard you need to connect those pins to your circuit as well. I'm pretty sure this is what's missing.
    If not, then attach a zip file with your circuit file.

  • How to use lab view to do slew rate experiment

    gud afternoon
    I have an op am
    p circuit built on the NI ELVIS board and I input a square wave from function generator to the circuit. I have to determine the slew rate of the op amp.In the labs, one would run the square wave over a range of frequencies and stop when the square wave looks like a triangular wave. At that frequency, one would then measure the slope of the signal and that will give you the slew rate. How can I do that in LabVIEW? How can I check when my square wave starts looking like a triangular wave? please help..............................................​...............................
