How to read the digital square wave pulses

Hello

I recently bought a blue-white meter. I have successfully read the digital square wave from the sensor. However, I face a problem to calculate the flow rate and the total volume of liquid. Can someone help me with this?

Technical data of the flowmeter can be access to the http://www.blue-white.com/Products/ElectronicFlow/MicroFlo/80000-406_microflo.pdf. And the calculation can be found on page 9. I use NI9401.

Thank you

  • How to read the digital I/o using PXI-7813R?

    Hi guys,.

    I'm reading a digital signal by using one of the ports in the PXI-7813R. The 7813R has 5 digital ports or 39 lines for playback of digital data. I have connected a SCB-68 as the physical hardware interface for 'plug-in' a 5V adapter, which will act as my signal at the moment.

    After you configure the PXI via MAX, I wrote two codes, one for my host pc and the other to control the FPGA through the host. But I think, I can have more complicated or completely gone in the wrong direction.

    Any help in the drafting of these codes would be well appreciaetd.

    Thank you, Anoop

    You need the FPGA to sample the signal how often you expect the device to send the data.

    If you write your data in the FPGA for the DMA, then on the side PC you just have to read the DMA.  I like to think of the DMA as a queue.  It makes it easier for me to understand how it works.

    Unfortunately, files .wav is not supported by the phone. You can convert the audio file to a different format by using an audio converter application so that it can be played on the mobile device.

  • Digital square wave

    Hi all

    I want to check if my digital square wave turns on or off. If someone has an idea, please help me

    I created a mask, so that if my signal leave the mask. I have an Error Message. "It's job but every time I should change the values of the function Culsters ' specification limit" if I change the Signal

    You will find in the attachment the block diagram.

    Thanks in advance for your answers

    Best regards

    How are you brightness measure?  A digital signal is enabled or disabled.

    Duty cycle that you can measure quite simply.  There is a VI called Pulse Measurements.vi who will do it for you.

  • How to remove the digital ID

    I have a digital ID in Adobe Reader X and forgot my password.  Because I don't believe that these passwords are recoverable, I need to delete the codes and start again.  But when I go to edit, then the protection window that opens is very light and I can draw anything to the top of this window. Can someone help me this this please?

  • How to read the status of User1 DIP-switch with a cRIO FPGA chassis?

    How to read the State of the DIP switches on a FPGA cRio chassis?

    I work with a cRIO 9022... My idea is to put the system in "service" mode with USER1 switch to IT and communicate with the FPGA via the FPGA - GUI (VI) on the host computer instead via the RT module that is used in normal conditions.

    Any ideas? Unfortunately, I don't have an unused channel on the left... .and (as I know) cannot use the interface RS232 of FPGA.

    Many thanks in advance,

    Luke

    Hi, this is the correct information. You cannot read the FPGA of DIP-switch status. The only thing you could do is to use the function of Reading Switch.vi located under the range of functions-> real-> utilities RT time

    It's how you probably know side host RT and not the FPGA.

    I have a lot of list boxes on the front of my VI. I want to know how to read the value of this combo with a loop boxes For. The point is that I don't know how to get the reference of each combo box in a loop.

    Any information would be welcome. Thank you!

    If you have VI Analyzer installed, you can load the configuration file and look at the section select the Tests. There is a test for the maximum size of front under front-> User Interface. The default value is the resolution of the current monitor of the PC (including multiple monitors). You can change to the desired option.

  • How to read the two columns of data from the Port series

    Hello

    I'm reading two columns of data from the serial port.

    Example:

    52209 52214

    I want to both sets of chart data.

    I enclose my VI.

    Thank you for your help.

    The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

    pop up on the wire table refernece and establishes 'control '. Add this control to the icon of the sub - VI decision-making and then wire ref of the appellant to this Terminal VI so the calling VI move the ref to the Subvi.
