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.

  • 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.

  • How to read the Serial Arduino data using labview VISA?

    Hi =). Im a beginner work reading data series from an arduino but im facing... Lets do it step by step

    I built a voltage divider circuit which gives from output
    from 0 to 5V. The output of this circuit is sent to a 0 analog input pin
    of a Committee of Arduino Duemilanove.

    (1) Firstly, I connected the cable to connect to my laptop USB the Arduino.

    (2) I went to start-> control
    Control Panel-> system-> hardware-> Device Manager. Check the Ports (COM
    & LPT). In my laptop I can see USB Serial Port (COM4). Now I know only in
    LabVIEW that I must read the data series COM 4.

    (3) to the side of the arduino, here's the code to read changes in voltage
    entered to analog pin 0. The last line of 'delay' determines the sampling
    Rate of how we want to taste the output of the voltage divider:

    int potPin = 0;    Select the input pin for the output of the voltage divider
    int val = 0;       variable to store the value from the probe

    void setup()
    {
    Serial.begin(9600) (9600);    Opens the serial port, establishes the rate of 9600 bps data
    }

    void loop() {}
    Val = analogRead (potPin); read the value of the voltage divider
    Serial.println (Val);
    Delay (10);
    }

    I slightly modified the basis series reading writing VI... I have
    attached the block schema used with comments. Basically, I tried to read
    data series, divide by 1023 and multiply by 5 to graphic voltage
    variations of the voltage divider circuit.  But Im not getting
    the correct voltage output values. The value of the tension just keeps go
    0 and coming again, as shown in the photo.

    Could you guys please guide me on what went wrong?

    Thank you!

    -you read the data, even if there is no data on the port. If 0 bytes are read => «»

    -in the case of false, you resources VISA wired for the output of channel tunnel?

    -There is no close VISA at the end of the VI resources

    -you're not a loop this VI reading bytes

    I added an addaption of your VI that you should give a try maybe

    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.

    Don't know how to read the results of netstat EI s list? If I received 860592506 bytes sent from 43421482 how to convert MB? And does this mean byte received?

    Hello

    This shows the total number of bytes transmitted and received via the Ethernet card. This is the total of the amount of use up to this day.

    This includes all the Web sites you have visited and emails you sent, etc..

    You can calculate using one of the following methods:

    Method 1:

    860592506 / 1048576 = 820,72 MB

    Method 2:

    Multiply 860592506 with 9.53674316 * 10 ^-7 that will give us the result in mega bytes.

    860592506 bytes = 820 MB 9MB not, accept my apology for the miscalculation.
    Similarly 43421482 acroos = 40MB

  • How to read the values of the field of LOV disabled?

    Hi all

    I have a requirement, based on values that we entered one of the LOV fields, then we are arising from the new values based on the value that we entered this field of LOV. And then I must by default new LOV values derived in a two other fields of LOV and then disable them. Once the fields are disabled, then I'm not able to read the values using the pagecontext.getparameter... I get nothing when I tried to read using the pagecontext.getparameter.

    Pointers on how to read the values of disabled field/LOV?

    Thank you
    Clarriiza

    1. you already have values, and that's what you set in the LOV before turning off, right? So why do you need to recover again from the LOV.

    2. are you disabling or making it readonly? I think that if it is disabled, you might still be able to get the value using pageContext.getParameter.

    3 have you tried to get the handle to the LOV bean and get the value using lovBean.getValue (pageContext)?

    4. another Option is to combine the value of a FormValue Bean also (as well as the LOV bean) and retrieve it from FormValue.

    5 BTW, why are, why you're seen LOV if you disable it? Can't you just a TextBox?

    See you soon

    Hello

    My Jdev version 11.1.1.7.0.

    I'm Executive where clause programatically where I need to bind two bind parameters under certain conditions. Example, I have two bind variables X, Y.

    Here's the problem:

    Assume that the first time I'm setting one variable X, so I define X bind variable and execute the query.

    What second time I send only Y but not X. In this implementation of the scenario of VO throw an exception, given that the variable X is already created in the VO object and where clause does not have this setting.

    So how to remove variables created in the original Version all in definedNamedWhereClauseParam(). I need to erase what ever the previously created variable every time I execute method.

    I can make the similar functionlity using setWhereClauseParam (using literals). But I have a few technical restrictions for use.

    Could you please help me how to remove the variable before vo using definedNamedWhereClauseParam.

  • How to read the value of an independent textInput element inside the method?

    Hello

    I had a group of detail based on a readonly viewobject. I added an independent element textInput, you say, EndDate to this group that the user can enter a value inside. Now, when I run the app I select a row in the table and press a button that triggers a method inside a bean. My question is how I read the value in independent textInput (EndDate) within the method element?

    getTable () .getRowData () does not print the unbound attribute. It seems that it only contains attributes underlying viewobject

    I use JDev 11.1.1.4

    Kind regards
    Will do

    Will do,

    You can better create a transitional attribute for that in your view object, so you can use a regular expression #{row.bindings...} to get the value.

  • How to manage the photos Lightroom when using 2 computers, keeping any changes made on one or the other?

    Based on http://forums.Adobe.com/thread/1308132?TSTART=0 I decided to add each question separately:

    Hello, I am very interested in buying Lightroom 5.2. I tried the RC that was missing today. Yet, I have several questions that I can't find really good conclusive answers, I'd like to get an answer before buying LR. Please do not write maybe like this or that (assumptions), because I don't want to start my entire workflow and then realize that I have to change all around, please reply, if you know for sure that something works and you are, preferably, using this method too.

    Is the big question, where I want to especially a conclusive answer:  How to manage the photos Lightroom when using 2 computers, keeping all the changes made on one of them, using the same photos for editing. I'm not going to use DNG. Details: I mainly use my old MacBook Pro, but I wish I could use my PC as it is much better (card: i5 2500K, 16 GB of RAM, SSD, USB3, nVidia GTX 560 TI etc.). I have 2 external HD that I could use, one for backup and one for the actual Photos/changes. I you will probably need to use as my internal HDs are fairly complete and I cannot be the kind of things simply delete or move to one (developer, without loss of music, programs etc.).

    On this basis, how do I save all such Photos folder (pictures and retouching and preferably presets too)?

    According to me, that it should be possible to work cross-platform without having to create a link to the files each time, or without having to keep export/import of the catalog, keeping the single catalog and the picture library on an external drive that is then switched between systems as needed.

    Obvious first requirement is an external drive that is formatted in a way (for example, FAT32) that it can be used on both platforms in read/write mode. Given that, if the catalogue AND folder parent si le catalogue ET le dossier parent images are both set to the same level in a global parent folder, then it should be possible to take advatage of ability of Lightroom to use relative paths instead of absolute paths to detect the images, no matter if the player is named (Mac) or lettering (PC). This is how "export as catalog of ' works, that is, it creates a 'package', alias a parent folder, containing the catalog and a replica of the folder hierarchy to exported along with the catalog images. Take this 'package' to another system (same OS or not) and "it works" even if the drive letter is different or the operating system is different... because the relative path of the image catalogue is always the same.

    I have not tested this cross-platform (if I have between various PC systems with letters of different readers) so for me it's still just a theory, but there may be others who have done this successfully.
