Data in FPGA application channel switch

Hi all

I use cRIO 9074 and NI 9234 to collect data of vibration with FPGA mode. However, I found the data I collected were some strings under tension. For example, I have two NI9234 modules (8 channels). I found the first channel may have the value of the data that should be in channel 8. It happens randomly. And also, the swich channel happens between data points (sometimes around 50,000) already. I think the switch happens in time real VI when I read the FPGA FIFO data. I used the structure of stream flow data from the real-time host controller network. In the host vi, I can save the data when I need to.

The screen is suddenly I joined the one 62123 samples, there are 3 samples shows the value of the other channels.

I have attached my programs. Hoping someone here can help me out. Thank you.

Remember to see your problem. The "greater or equal" Don t make sure that the number of elements is divisible by 8. The way I'm going to do is to check the number of items on the buffer, divide by 8 and check if the reamainder is not equal to zero, if true the number of items read less reminder, so fake read the number of elements in itself.

  • FPGA AO channels are often damage

    Dear all,

    I m facing a problem in my card series FPGA 7833R (with PXI controller 8108 RT, 6229 PXI, PXI-6514 in chassis PXI-1042), in the FPGA AO channels is damage frequently, here I m using FPGA to order Festo 2 taps using PID and one of 6514 card are physically connected to DI in FPGA to start/trigger control PID. I m using parallel loops in FPGA to control 2 valves of festo. Loop1 with AO0 will controll Festo valve 1 and 2 with AO2 loop control festo valve 2 and both channels are harmful, what could be the cause of damage. Kindly help me findout the problem.

    With respect,

    Vipin

    The most likely cause is back emf of the coil of the valve.

  • Data storage local application?

    Hi all.

    I want to store the data of the application installed on the PlayBook.

    Anyone knows where is this dedicated space and how to access?

    The main use is to use a SQLite database (but not only).

    (What is possible with the simulator at all?)

    [Edit: the message is more specific.

    Hello Julien, thanks for the reply.

    In fact I tried to use ApplicationStorage already, but I got a 3003 error: exception "file or directory does not exist.

    When I run the App in internal Flash Burrito Simulator, there is no error: the db file is correctly detected.

    But it seems that File.applicationStorage is not on the PlayBook Simulator.

    Is there a simple test to check the correct path to the App store?

    [Edit 1]

    Some news: I could verify that the ApplicationStorageDirectory is finally ok (correctly created in the card Sim PlayBook.)

    The problem actually comes from ApplicationDirectory, where I get the "source" file load in the dbFile.

    If the command "File.applicationDirectory.resolvePath("assets/MyFile.ext"); ' return something like:

    "/ mlc/sandboxes/guest/PROJECTNAME.debug.XXXXXXXXXX/app/air/assets/MyFile.ext".

    (XXXXXXXXXX seems to be the ID of the deployed project series)

    And if this file "does not exist" when I access it.

    (reminder: it works very well in the internal Flash Simulator)

    Is there a simple test to check the correct path of the deployed application. ?

    (always to research...)

    [Edit 2]

    Well, it seems that the solution was related to the embedded file (or not) during deployment.

    So I have included the file I need (xml file) in the line of command deployment, and it was found correctly on the PlayBook, using ApplicationDirectory (as described by Julian).

    Just for review, I first tried to include the 'active' comprehensive directory, with an error that results from:

    java.lang.IndexOutOfBoundsException  at java.io.ByteArrayOutputStream.write(Unknown Source)    at com.qnx.bbt.deploy.Deploy.readPackage(Deploy.java:173) at com.qnx.bbt.deploy.Deploy.verifyPackageId(Deploy.java:138) at com.qnx.bbt.deploy.Deploy.sendRequest(Deploy.java:124) at com.qnx.bbt.deploy.Deploy.run(Deploy.java:100) at com.qnx.bbt.deploy.Deploy.main(Deploy.java:73) at com.qnx.bbt.airpackager.BarAirPackager.callLauncher(BarAirPackager.java:206)   at com.qnx.bbt.airpackager.BarAirPackager.run(BarAirPackager.java:129)    at com.qnx.bbt.airpackager.BarAirPackager.main(BarAirPackager.java:78)Error: null
    

    (It may be related to a specific inside assets... file or directory size... but this isn't a big deal)

    Then, finally solved. Would be the last word: do not forget to include the 'active' files you need!

  • Data shared between applications

    Hi all!

    I am writing a small application, and I wanted to separate the user interface in two applications to reduce by clicking. But they have a lot of data in common, so I thought that maybe I should have a third application that manages just the push / pull aspect? I'm doing exactly how (if we can) share data between two applications?

    An XML document or something like that would be perfect. Maybe a few pictures, if I'm really lucky.

    I would also say RuntimeStore if data should not be persistent and the images become large, then don't look to put it on the SD card.  You can also consider RMS store, but for a native Blackberry application, the other options are probably better.

    You can store an XML document in all these places, but this means that you will allow the analysis whenever you need to get some data from it and/or update some information there.  PersistentStore and RuntimeStore are object storage, you can store the object analyzed, what could be more effective.

    Suggestions apply to date only if the data is dynamic, if the data is static (for example, the code and still images), then you can create a shared library that is used by both applications.

    I think that all of these options are discussed to some extent in the developer's Guide, I would say you have one skimmed through here.

  • Failed to add data to an application

    Hi ~

    I meet a problem in the studio of discovery short, my discovery workshop, the "Add a data set" button or "add records" option will disappear under data set. Although still able to create points of view, but is no longer able to add several sets of data which is very annoying, I essentially have to re - create the application again. It seems happens whenever someone does some work for export in the side ETL at my request. Anyone who has seen a similar question and maybe share with me? Any ideas would be useful. Thank you.

    Yes, this is how it works.

    The thing to remember is that each application is associated with a single domain of short server data. When you ingest data using Integrator, you create the data domain, use the short servers page in the control panel to make it available in the Studio, then select as the source of data for your application. Other users can also create applications using this same data area.

    When you create an application from a worksheet, Studio creates a new field of data and assigns it to the application. This type of data field cannot be used to create other applications.

    The basic assumption is that a field of data created using Integrator/ETL (sometimes referred to as 'curated data') is managed/controlled/made available by a COMPUTER group, which would be non-random users, adding data from their Excel spreadsheets.

    Areas of data created using a spreadsheet (sometimes referred to as the "self-service") belong to this user. Anyone can change the application can add more data from other worksheets.

  • Install PT8.53 with Linux question: connection process Data Mover and application designer

    People,

    Hello. I install PeopleTools 8,53 Internet Architecture.

    Server database is the database Oracle 11 GR 1 material.

    Operating system is Oracle Linux 5.

    I installed successfully JDK7, WebLogic Tuxedo 11 GR 1 material and PeopleTools 8,53 10.3.6, in Oracle Linux 5.


    I've been setting up of database PeopleTools8.53. Because the Wizard installation problem, I created PeopleTools 8,53 database manually by using starter PT853 Oracle database instance. I have run the following scripts:
    (1) utlspace.sql
    (2) dbowner.sql
    (3) ptddl.sql
    (4) psadmin.sql
    (5) psroles.sql
    (6) connect.sql


    Then, we perform Data Mover script in a Windows XP Client computer to fill the PeopleTools PT853 database machine Linux Sever instance.

    I installed Oracle Database 11 g 2 client for 32-bit Windows XP 64 - bit Windows virtual machine and run it successfully.

    In Oracle Linux 5 Server Machine Net Manager:

    Service name: PT853
    Connection type: default database
    "TCP/IP Protocol".
    Host name: 192.168.196.102
    Port name: 1521

    Listener: LISTENER
    Protocol: TCP/IP
    Host: 192.168.196.102
    Port: 1521


    I test the Service PT853 with "SYSADM" username and password "SYSADM". The connection is successful.

    In the Windows XP Client computer, the information in the Net Manager is the same, and the connection is successful as well. Its details are as below:


    NET Service Name: PT853
    Protocol: TCP/IP
    The host of the database Machine name: 192.168.196.102
    Port number: 1521
    Name of the Basic Service: PT853
    Connection type: default database


    This means that Windows XP can connect to Oracle Linux 5 successfully. But in the computer Windows XP Client, Data Mover and application designer cannot open a session in PT853 Instance of database in the Linux Server machine. Its details are below:

    Configuration manager:
    Type of database: Oracle
    The database name: PT853
    User ID: SYSADM
    Connect ID: people
    Connect password: people

    Data Mover:
    Type of database: Oracle
    User ID: SYSADM
    Password: SYSADM

    Application Designer:
    Type of database: Oracle
    User ID: SYSADM
    Password: SYSADM

    When connect Data Mover and application designer, I got the same error:

    ORA - 12154:TNS: can not resolve the connect identifier specified. Invalid user ID and password for the access code.

    According to my understanding, process connection Data Mover and the application designer requires 3 tables in SQL Server: PSOPRDEFN, PSACCESSPRFL, PSSTATUS. I'm not sure the process of connecting to the Oracle database. I checked the database PT853 instance in Linux, and there is only one table "PSDBOWNER" created by the scripts.

    My question is:

    Can any folk tell me the connection process Data Mover and Oracle database application designer? Requires only one table "PSDBOWNER"?

    Thank you.

    Oh my, many mistakes action here. If PSDBOWNER doesn't have a line, it must be solved at the time that the error came out. The replacement by SYSADM first why? Why is complaining already existing SYSADM? Most likely, you HAVE created manually, where you shouldn't.

    Again and again the same story. And again, sorry to say but you should take the basics of Linux training, Oracle training bases and sorry to be hard but reading training as well to read correctly the Peopletools Installation Guide where all required steps are really described in details.

    I don't think anyone can help you across the network in this respect,

    Nicolas.

  • share data between two applications

    Using the class SharedObject can operate only in a single application, but if you start a second request, this SharedObject does not its value (zero) already set from the first application.

    I remember correctly, there is a setting to allow work between applications. Also you must be sure flush() to save the data.

    Another option is LocalConnection.

  • Determine the Sources of data used by Applications

    We are still currently using MX6.1. Our team of Oracle is upgrading to a large amount of databases (at the beginning of DEV, then QA, then Prod) which connect our various applications see I'm pulling my hair out I am trying to figure out/map which applications use a particular data source. I know that when I go into a sandbox given via the web administration I see sources of data that an application is allowed to use. It would be terribly helpful if I could just go in the variety, defined data sources and see what sandbox (es) currently allow connectivity and would thus know which applications would be affected. Someone can shed some light on my dismal existence? Thanks in advance.

    Your method is easy.

    All the your DSN are saved in the file "cfroot\lib\neo-datasource.xml". You can open with an XML editor and view the settings.

  • the 1900 myRIO FPGA multi channel data acquisition

    Hello world

    I would ask you for help in my program acquisition and generation of data. The main task of this program is to measure 4-channel adjustable sampling rate (2 kHz and less) and to generate an analogue signal in up to 50 kHz sampling frequency.

    I created two loops and everyone is dedicated to different operation. The first loop is to measure data, or in writing to the DMA FIFO and the second loop is dedicated to the generation of signals. I adjust the main parametrs of the two loops in a host of vi.

    But what is my problem. I compile the program in the FPGA of myRIO without any problems and I can run too but the problem is that sometimes, especially when I adjust the lower sampling frequency of the loop to measure to the rank of channel changes measured and I see that the signal that is connected to osciloskop AI0 channel on channel AI3. When I stop the program, set the higger sampling frequency and run it again, it works well and the signal is on the right channel. Could someone help me with this problem? I tried to check all the forums that I know, but I did find an article or a discussion of a similar problem.

    Thanks a lot... :-)

    Andrew,

    I just solved the problem. I thought about it again and I got the idea to change the size of the DMA buffer on the side of myRIO. I expanded the buffer of 1023 elements in 2047 and it works well and I can change the sampling without problems.

    One thing to check is with the role that you started JDeveloper - you must use the default role to have active ADF.
    (check under Tools-> Preferences-> role) - If you started with another test of role the role - switching is it still didn't help - remove the JDeveloper system directory and restart.

  • How do MANUALLY enter you data into the application of health 10 IOS? There is no symbol and touch edit only gives you the option to delete existing data.

    I checked in the application of the health and read the Apple support page. They show the screen for 10 IOS on an iPhone, but their instructions don't work. There is not a Plus symbol to add data manually. It has only an editing tool that you can touch and only allows you to delete data.

    Hi, rmetzker!

    To manually enter the data points in the application of health, first go to the display of data on health as shown below.

    Then select category to which you want to enter data in (I'll use body measurements for example), then press on what data you enter (measurements > weight). In the upper right corner, it will be a plus + icon for you to manually enter your own data points.

    I hope this helps!
