traction control

I'm building a personal project that the traction system is my problem...

The main idea is: I put the desired distance, it moves up there, he returned to the same spot where he started (no need to be precisely at the same point... a few inches away or before is not serious) and have stopped

The problem is: If for example I set 100 feet, he traveled 100 feet, when it gets to 100 feet, it changes the digital output control relay (arduino to relay 5v card) to make moves backward, but when she gets any small tham number 100 feet, he changes again and try to travel 100 feet It tries to go in reverse, a kind of redundancy.

I use neither myRio and one with A quadrature encoder and channel B and 360 impulses per revolution

I have attached a VI that works like on the software, but I put a button that works as an encoder

Hello, Mr. Morris

Yesterday after a few tries, I found the solution for my problem.

The problem solved after I added a local variable to the VI. is attached to the idea of the software

Thank you for attention

  • How do I create a traction voltage as a control signal upward?

    I use a minimum/maximum statistics module, but is unable to route the analog data to all 16 entries that I need this module (I suppose a limitation of current car, but I don't know why this would be necessary in the software). My first thought was to use a Signal Amplitude controlled router to expand this case 15th signal at 16. It seems that, since I want the router to Signal to be always active (ON) that I don't want to pull up to command input the Signal from the router. How to create a pull upward which is common in digital electronics for this?

    It is not a limitation of current car, but simply that you can plug a wire 15 times, for up to 16 destinations. You can work around this by inserting a module of scaling, the NOP value, then its output for up to 16 more destinations.

  • Using microsoft TFS source control

    I'm putting in place source code in labview control using Microsoft TFS. I have installed on my TFS machine but when I try to implement source code control I get the None choice on the traction to the bottom of the box for the selection of the source control. The help file said it should Auto complete by reading the registry to determine what kind of source code control is used.

    Any suggestion would be appreciated

    Thank you

    Jim

    To connect with TFS an additional plugin is required. There seems to be at least two versions of the plugin - 2008 and 2010. Here are the links:

    2010

    2008

    Once the plugin is installed, an entry for TFS should appear in LabVIEW.

  • Jdev 11 g AD / display objects - updated and complete control of data to the web service

    Hi Experts...

    Looking for the best approach here.

    I hope someone can give me some ideas / advice on how best to achieve the filling of a webservice data control to a view object.

    Basically, I created an application traction of data sources by using the ADF BC VO tables I put a command button "Update record", that will open a dialogue with a web service data control.

    I hope to be able to fill in the fields of data control, with the values of the selected recording VO.

    I'm tipping at this point, I'll have to programmatically?

    This is the recommended approach?

    Examples of code?

    Thanks in advance to anyone who can help!

    Simo

    Should be similar to this:
    http://blogs.Oracle.com/Shay/2011/03/passing_parameters_between_web.html
    But the first page should get the data from the original Version instead of Webservice.

    Since you use API-PL/SQL in the database to make the update, it may be more efficient to have just a method of AM service that uses the existing JDBC connection / transaction and calls this PL/SQL stored procedure and passes the info of the VO.
    See: http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/bcadvgen.htm#BABEIFAI

  • Lack of shot-up music/Audible in iOS 10 controls

    As a regular sound listener, I regularly used blow-up controls music on pause or go back as you drive an audiobook to keep my GPS map display on the screen. Since the update to iOS 10, shot-up music control buttons disappeared. Unless there is a more simple solution, I spend Waze audible, which is much more distracting and may be dangerous. Has anyone here found a solution?

    Hello chemess,
    Thank you for using communities of Apple Support.

    I understand your message that you want to use the audio controls in the control panel to control your audio books using a GPS navigation app. I understand your desire to not have music controls in the Panel. Controls the music is accessible from the control panel by opening Control Panel and slide the Panel to the left.

  • BONES of Sierra crashing to the LOGIN screen while using the service of mission control.

    After Sierra OS upgrade my MacBook Pro hangs on login screen every time I have used the function of mission control.

    Hey hernj103,

    Thank you for using communities of Apple Support. I can see your post after upgrading to Mac OS Sierra that reboots your MacBook Pro, if you use mission control. There could be a number of reasons that could cause this and I want to help you have a reliable working Mac, so I'm here to help! If you have not already done, you want to make sure that you have a backup of your data and you can use the option in the link below:

    Use Time Machine to back up or restore your Mac

    Once your data is secure, you'll want to test this function in Mode safe mode and see if you get the same effect. Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening. Also, it verifies your startup disk and trying to fix problems if necessary directory and delete font caches, hiding the kernel and other files of the system cache. The following link can show you how to start your MacBook Pro in Mode safe.

    Try safe mode if your Mac does not end commissioning

    If you continue to have problems after the safe boot mode, let know us and we can continue to solve the problems there.

    See you soon.

  • Precise control of mixer

    Hello

    I wonder, is it possible to precisely drag/move/move and knobs in Logic Pro X mixer? I mean that normally if you click and hold the slider and make it slide simultaneously works normally. But as I remember in other DAWs method with using the key 'control', or 'command' or something like that and that didn't exist by dragging the sliders is very slow with accuracy.

    But I can't find this option in Logic Pro. Could you help me? Thanks in advance for any help.

    I'm sorry for the stupid question, I would never ask for such a thing in the forum, but I really just spend an hour to find the answer in google. Without doubt, I used the wrong keywords, but I tried a lot of things and found nothing that helps me. So maybe you could help me?

  • Audio controls from the control center was lost in iOS10?

    Updated reluctantly iOS 10 and so far, the biggest annoyance is that my playback controls for some audio I play (audiobook of iBooks, podcasts with downcast, stream radio KPCC app) disappeared from the center of control... any way to recover?

    Quick scan power button or mute with the least amount of taps & shots is important when you want to respond to someone knocking on a door, or on the land line call, etc., and have hit to swipe several apps to reach the audio application when you were in another is an unnecessary extra step.

    Is there a way to get this back that I missed?

    In iOS 10, audio controls have been moved to a second page in the control center and are accessible by sliding left within the control center.

  • Why is forgetful of Parental control?

    Why Parental controls (often, not always) forget and do not take account of my settings?

    I have, for example, deselected some apps, but when my daughter logs in to his account on our MBP she gains unfettered access.

    Is there a sequence in which the parameters must be defined? What I am doing wrong?

    Hi CreativeSmith,

    I understand that you are experiencing some problems with getting the parental controls and Restrictions work correctly on your Mac running macOS Sierra. Please take a look at the links below to verify that you have the Parental control configuration correctly.

  • Sierra: key control and command swap?

    Hi all

    I use the option to swap the keys of my command and control, but it does not work on my 5 k new Imac. It did not work in El Capitan. I have already reset the NVRAM but no luck, the control keys keep order and even for my control keys. Bug?

    Kind regards

    Peter

    Thank you for using communities of support from Apple, PeterWeter!

    Congratulations on your new iMac! I see that your iMac on macOS Sierra is not allowing you to change your key options. Since I have been hit most of my adult life, is not able to use any key how I need you would slow me down.  I'll be happy to help you.

    Try safe mode if your Mac does not start -boot in safe mode is a great way to make sure that everything starts correctly.

    What is safe mode?

    Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening. From your Mac in safe mode does the following:

    • Check your startup disk and attempts to fix problems if necessary directory
    • Loads needed kernel extensions only
    • Prevents elements start and the login items open automatically
    • Disables the user installed fonts
    • Delete font caches, hiding the kernel and other files of the system cache

    Once your iMac starts up in safe mode, you should be able to define the keys on your keyboard as you want.

    See you soon!

  • Ios10 control center

    I just updated my iPad iOS 4 10 and I noticed that the flashlight, the night shift and the calculator have disappeared from the Control Centre. When I open the Panel there are 2 boxes, one with the airplane, wifi, Bluetooth, do not disturb and orienration lock, Airplay mirroring, Airdrop, levels of brightness, timer and camera.  The second area of island are commands of the music. Can you point me in the right direction as to where the missing icons are gone please?

    I wonder if there is a difference between iPhones and iPads. I see on my ipad, night shift, but the flashlight is not there because there is no flash on the ipad. And no calculator on the ipad but I have one on my ipod.

    The inconvenience of having a manual based on the iOS instead of the device, the iPhone and the iPod have different capabilities than the ipad and vice versa.

  • iOS 10 remove airplay and release of the control center.

    The airplay and drop buttons occupy too much space in the control center. This space would be more useful if it were the music app. I do not have now any use of airtime or air drop and would really like to be able to hide these buttons.

    In iOS 10 slide the left control center and you have control of everything for the Music Center.

  • Controls horizontal volumen in macOs Sierra

    Hello

    With the new volume control available under macOs Sierra (horizontal slider) now you can't click and drag the volume control that I used to do! Was perhaps than me, but I used this technique (click and drag) a lot of time for speed and simplicity.

    If it's a matter of UI design, I think it's pretty easy to keep the cursor in the vertical volume with a list of outputs available on the right side like this:

    So please! go back to the vertical!

    FWIW. the horizontal slider works for me.

    I doubt that the problem you are experiencing has nothing to do with the orientation of the slider.
