VI quadrature encoder does not work after programming of FPGA

I'm rather new on the MyRIO, and I work on the motor of the MyRIO and read control in a quadrature encoder at the same time. Programmed individually, the two pieces of work at Marvel, but once I have combine them and try programming, control of motors not to not work signals, but the reader encoder does not work. I use the Express VI for the LabVIEW quadrature encoder reader, and I produce four stepper motors signals using FPGA.

It seems as if the encoder is disabled when I program the FPGA with my code, because if I have two parallel loops, one for the reader encoder and the control of step motors, if I stop the loop of step motors, the encoder works immediately.

Is there something simple that I'm missing?  Any suggestions would be greatly appreciated!

Thank you

I realize now that my last answer could have been confused and not useful to someone else who may come across the same problems later.

Here is how I solved the problem I've had:

I had to derive Boolean expressions for an encoder quadrature (essentially to create my own) and then used the outputs (UP, DOWN) to increment/decrement a counter using the conditional statements. Then, I stored the value of direction in a flip flop implemented using two conditional statements of T/F in series and connected to a shift on the edge of the loop register.

It was all able to be implemented in a single cycle timed Loop, and then I managed to place in the same loop that I used to control stepper motor.

In this way, I could have a VI collected in a Bitfile and could be programmed to the FPGA.

Hope this is clearer!

    Hello

    What happens when you start the webcam app?
    All programs-> Toshiba-> webcam

    Did you install other 3rd software part as for example the Skype that could access the webcam?

    Extra tip: go to BIOS and set it to default, save changes, and then restart the laptop.
    Start Skype for example, check the settings in Skype webcam chose correctly.

    It would be really interesting to know if the other software would be able to use the webcam.

    By the way: have you installed Toshiba face recognition? This software use and access the webcam as well
    Then sometimes it would be possible that this software could block the webcam and webcam tool could not work

  • HP deskjet 3510 does not work after windows 8.1

    My printer HP Deskjet 3510 cannot be detected after windows 8.1.  My computer is a HP Pavilion g6. Now, I would never, I clicked to install, I wish they would send me just windows 7. Laughing out loud

    @klb75,.

    Thanks for posting.

    The cardinal rule of when something does not work after update to 8.1 is put it back in place. This applies to the printing software and all other software. Uninstall from the control panel configuration, programs and features. Then, restart the computer.

    After that, download and install this software: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=al-108718-3&cc=ca&dlc=en&lc=en&os=4158&product=5157483&sw_lang=

    * Thus, before installing the software, disable all Firewall/antivirus software. This software can create conflicts with the printer software.

    If reinstalling it does not help, run print and scan doctor. He could fix it... http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?CC=CA&LC=en&JumpID=ex_r4155/HHO/IPG/ccdoc/printer_diag/&softwareitem=MP-135113-1

  • Installation of Windows service does not work after Windows Explorer 9 uninstalling and reinstall Explorer 8

    Installation of Windows service does not work after Explorer 9 uninstallation and reinstallation of 8.  I followed several suggestions on this forum, but still no luck.  I ran the SFC system twice, who told me he had corrupted files.  "Some have been repaired and some might not be."  I then went in the event viewer after a start to the top and he stated that the 'Adobe APM service' is not found.  Also the "hpqddsvc' and the 'gupdate' is not found.  He tries to install something every time I start, but he abandoned.  I checked whether the system is on and disabled.  It's on.  There are a lot of small problems, but my main concern is the Adobe program.  I tried uninstalling and reinstalling Adobe, but still get an error message that the Windows Installer Service could not be accessed. Other suggestions?

  • Serial number does not work after the transfer of OSX and apps for the new Macbook Pro

    My serial number does not work after the transfer of applications and OS X for my new Mac.  Although the Adobe specifications say it is compatible with the older OS X, it does not seem to have no compatibility issues because

    -My old Macbook Pro has Yosemite and was fully running CS5 Web premium without a problem.

    -My new computer has the same * exact * OS X transferred in which the suite was fully functional with the trial.

    A support of top-level, software engineer, or someone who takes care of the soap operas could

    -Please provide a number of test series to test with?

    - And/or activate my series?

    - Or show how to disable the publication series on the old disk hard if I can't use the old computer?  So that I can use with the new computer?

    I chatted with technical support that keeps saying that it's a compatibility problem, to install with old OS X or buy a newer version. But I know that CS5 works with Yosemite (as I use it myself), and the only question I had is that serial # says invalid, which is separate from the functionality of the program.

    I'd rather not spend hundreds more to get a new suite, when I spent a lot for CS5 already and know is fully functional on Yosemite.  I have also not return to an older operating system and break things.

    Moreover, I used to be a general technical Support and I am a coder of web applications, so I understand that this isn't just some sort of "reboot" of the question

    No info to solve this, or a means to achieve at the highest level Tech support, would be greatly appreciated!

    Thank you!

    Transferred apps will certainly question of activation, because licenses files creation is completely dependent on machine, it willl created according to the particular Machine ID, if you transfer the application from one computer to another, there is incompatibility.

    Therefore, it is very necessary that you are using the original installation media.

    If you do not agree with the process of removing and reinstalling, try wiping the contents of SLCache and rename the SLStore folder.

    The home button works on the first push to wake the phone but it will not open the phone the second button.

    I activated the assist button, which does not work either. But what I discover is if I open device for assistance then touch and lock screen click on the button home will work once to open the phone. If I open any app I can't close it unless I go through the same routine.

    You can do so by holding the sleep/wake button and the Home button simultaneously until the Apple logo appears

    Please solve this problem as soon as POSSIBLE

    Hello guatamshah,

    If your USB to ethernet adapter does not work now that you have upgraded to Mac OS Sierra, there are a number of things we can try to get it working again.

    The first thing we want to do is to reset the SMC and the NVRAM on your Mac.

    How to reset the NVRAM on your Mac.
    https://support.Apple.com/en-us/HT204063

    If the adapter is not still work after only two resets check to see if your Mac recognizes the device properly in the information system. In the Apple Menu, choose about this Mac, and then click the button 'system report... '. ». Once you have the window open system information, see the USB category on the left.

    However, if you do not see the device in system information, you may need to verify that network service appears correctly. In the Apple menu, choose system then Network preferences. You should see an entry similar to "Ethernet" on the left. If no, see the steps in the article below to add. Once add, test to see if your connection works with a disabled Wi - Fi connection.
