Custom output device

• More questions about custom asynchronous device

  I am trying to create a custom asynchronous device for VeriStand and have the following questions:

  (a) at what rate entered in the course of analysis and data channel pushed into the FIFO of the custom device entry? The scanning speed depends on if the input channel is mapped to a control of workspace object or if it is mapped to an output of the simulation model (.dll file)?

  (b) at what rate the VI real-time asynchronous custome device running? Is it at the same rate as the primary control loop rate? Can I change the rate of implementation of a custom device and how?

  (c) I have a quad-core PXI time real platform. How can I connect the device customized to a specific processor, like what you do with a simulation model (.dll file) in the definition of system file?

  Thank you in advance.

  Data FIFO

  The rate at which data are pumped on your meter is static and has nothing to do with the question of whether the workspace is connected, or if a model is mapped to one of your channels. By default, data are pushed in input of your Custom FIFO each iteration of the loop of primary control. If the FIFO is full, the oldest data packet is crushed. In addition, by default, outings THAT FIFO is controlled ever iteration of the loop of primary control. You can, however, use the NI VeriStand - Set custom decimation of device to mark a property on your customized device that will tell the system its decimation expected in the. If you set a decimation of 10, for example, the primary control loop will be send every 10 iterations of new data and check for new data out FIFO only every 10 iterations. This can help reduce the load of the processor in your system if you do not need updates that often.

  Similarly, you can use the NI VeriStand - Set of deep FIFO to control the depths of the FIFO of your entries and exits FIFO respectively. By default, both have depth 1.

  Delivery rate

  The rate at which your custom device runs depends on how set you up. You can for example, having your Custom asynchronous device uses its own schedule and run at a pace totally independent of the system. Your VI could have regular while loop with a 10ms timer, for example, or it could be based off some hardware device timing.

  Alternatively, you can choose yourself closely synchronize with the primary control loop. This by registering using a property that your Custom device has a timed loop that will use the clock of the device. The unit's clock is a source of synchronization that is checked each iteration of the loop of primary regulation after Custom peripheral FIFO have been updated. You sign up for this simply by calling the NI VeriStand - Set loop property Type specifying Timed loop to loop type and use peripheral clock be true. Then, as the VI model, thread just the clock of the camera in your calendar input source for the timed loop. If you have specified a decimation factor, as mentioned above, you should probably also to use this factor as your dt. This means that if you have a decimation of 10, you only run your timed loop 10 all the graduations of the source of synchronization clock of the device.

  Another simple way to synchronize closely with the primary control with a few problems loop is simply base your timing off the coast of the availability of new data in your entries or exits FIFO. To do this, you can simply use regularly to loop and then just wire - 1 for FIFO wait times. Then your custom device will run as soon as the data are produced and consumed by the system.

  Specification of a processor

  There is no property integrated for the allocation of the processor, but it will be very easy for you to implement yourself. You can specify the processor to run on in the Explorer system by creating a custom using NI VeriStand - property set the property of the element. For example, you could define a property of I32 entitled 'Treatment', with-2 meaning auto-affectation and any non-negative value indicating an index of specific processor. Set this property in one of your device in System Explorer configuration pages and then read the property in VI of pilot in the engine using NI VeriStand - get the property of the element. Then just wire up the value of the property at the entrance of affinity processor on your timed loop. However, you should always check that this processor is on target. Otherwise the timed loop will report an error and abort. It's exactly what we do for models in-house.

• Custom output NXT

  I'm building a robot for a school project I need to use custom NXT inputs and outputs.  For my entry, I need the NXT to recognize a power transmitted by a detector of metal (between 1.5 and 1.9 volts) and then do an engine, specific degrees that correspond to a sorting device I did.  Secondly, I need a custom output that will send a voltage to a solednoid to life a diver to allow a coin falling into a hole.  I have problems of creation of code that will be run properly and perform actions desired... any help will be much appreciated.

• Vista - no audio output device

  Original title: audio

  After that 4 years of work properly my computer now tells me that I have no audio output device installed no advice please

  Hello

  Check with your system manufacturer (manufacturer of motherboard for customized systems)
  and to update or reinstall the ethernet driver. Be sure to use, if necessary,
  all methods in the resolution of the problems previously shown.

  It is possible that you have a hardware problem, would be unusual, but it's
  possible. And of course you can not fix the hardware with the software.

  I hope this helps.

• Is there no way to run an AIR application audio to audio output devices different from?

  I need to do a couple of our AIR applications select some audio devices to send their audio output, and last year, someone mentioned possibly using native extensions to do this.  I had to start working on other things for a while, but I'll be back to that (for the moment), and I basically learned how to create native extensions.

  But so far, they do not seem to provide me with any privileged access to what's happening under the hood of an AIR application.  When you stream live in via RTMP or RTMFP, details of the audio you are hidden.  It doesn't seem to be any place where you can actually access the audio bytes are sent on the network.  You can specify a certain object SoundTransform for the NetStream to use, but this class is final and one vanilla Flash build, so even though she may have a way to access the audio bytes, they are not accessible to all.

  It really seems that, when a NetStream starts streaming live audio, there is no way under the Sun for access to the bytes of audio and direct them to a certain audio output device, with or without extensions.  Is it so?  It would be unfortunate that Adobe does not allow it, even through the native extensions.  Thank you.

  Couple quick thoughts...

  The limits are important. There is a lot of work to maintain a clear separation between a decision to users and developers. For example, you cannot change an audio by default to users out because that clearly violates a decision to users. That said, this is a mess of people debating the issue and in fact finally a COM API without papers you can find allows you to actually do in Vista/Win7 (but not 8), but do not expect that it is a "right thing to do":

  lie lly-setting-the-default-playback-device-and-recording-device?forum=windowspro-audiodevelop http://social.Microsoft.com/forums/en-US/9ebd7ad6-A460-4A28-9de9-2af63fd4a13e/programatica

  You can get a drink before reading this.

  Incidentally, RTMP is secure, which explains why you can't access the bytes. The entire purpose of this is to ensure that their media cannot easily be copied or stolen media developers. Adobe don't document their method of securing the flow, but they do not publish the RTMP protocol specification. It is quite possible for you to create your own server method and encryption protocol RTMP while providing an RTMP stream to the custom client that you yourself the code which peut read flow. Here are the specs:

  http://www.Adobe.com/devnet/RTMP.html

  So I would say that it would be unfortunate if Adobe did give, you access the bytes. You might as well hand users an mp3 of a song because they steal left and right media.

  That does mean that you can not use a multitude of ways to get data via the default output device. Many applications (fraps/etc) captures audio streams video and mixed. But Adobe won't give you the keys of the Kingdom and allow you to decrypt protected multimedia Protocol.

• Update of the "couldn't find any output device" after the Sierra

  I've updated my iMac (model 14.2) of OS X El Capitan with macOS Sierra yesterday. The update went smoothly except that once the complete update, the Office and I logged the volume in the menu bar icon is grayed out. I immediately opened settings, assuming that the update had deselected somehow my default audio output device (a pair of external speakers, in this case). But when I went on the audio menu, I was surprised to see "not found any output device.

  I have looked around a bit and have not yet found anyone else with this problem. I became so desperate to get my audio that I even tried installing 3rd party 'Voodoo' audio driver, but it gave me the option for "Digital out (HDMI)" which is of no use to me, I have the mac connected to a TV via a VGA adapter and it does not have a HDMI adapter. One thing it stated however is that somehow during my got deleted and never replaced Applehda driver upgrade, or install a driver on 3rd wouldn't have added of output devices to list (albeit dimmed those outside and totally dysfunctional). So at this point, that I am at a loss, I know not how to replace the driver, where or how I would install it so any help is greatly appreciated. Danke!

  Hi Alison E.C..

  Thanks for the upgrade to Mac OS Sierra! I see that you have lost your audio output device once you upgrade. No worries. Great way to try to get your audio works using another audio driver. Given that this has not solved the problem, please try to reset the NVRAM.
  

  What is NVRAM?

  A small amount of memory on your computer called "non-volatile random - access memory" or NVRAM, stores certain settings in a location that OS X can access quickly. Settings that are stored in NVRAM are dependent on the type of Mac you use and the types of devices on it.
  Information stored in the NVRAM may include:
  The speaker volume
  Screen resolution
  Selection of boot drive
  These latest panic the kernel, if applicable
  If you encounter problems with these features, you may need to reset the NVRAM on your computer. For example, if your Mac starts up from a bootdisk other than that specified in startup disk preferences, or a question mark icon appears briefly at the start of your Mac.

  How to reset the NVRAM on your Mac.

  This should have your internal audio device showing as it should be under your settings in the system preferences. Please use the Apple Support communities to post your question.

  Have a great day.

• Is there a way to have Firefox respects the audio output device by default when it has been modified while Firefox is open?

  I've been a Firefox user for many years and I still use it as my main browser. A problem that has bothered me for years lies in the fact that when Firefox is open and I change my audio output device by default, Firefox does not respect this change and continues to play audio through the device that was used to originally. Even if you stop the audio and keep playing, does not change the output device.

  Is there a way that this can be configured in Firefox? Now, if I listen to music online (e.g. Soundcloud) I always use Chrome because it is respect changing the default audio output even in the middle of audio playback device.

  Reproduce:

  1. start audio playback (for example a YouTube video; HTML5 and Flash are affected)
  2. change your audio output device by default
  3. audio will continue to play the original output device

  Thank you!

• WANTED m6 that no audio output device is installed

  Hi, I was looking at a CD on my m6 DESIRE last night and it worked fine.  Today, I have the speaker with a red icon in the lower right corner of the screen and when hovering over it says "no audio output device is installed".  I tried to uninstall the device driver, but that didn't fix it there.

  The driver for device "IDT High Definition Audio Codec" under sound, video and game in Device Manager controllers also has a yellow exclamation point.  When I uninstall and reboot, sometimes just with the yellow mark again.  If I try to upgrade the driver, I get an error message "Windows found driver software for your device, but has encountered an error trying to install it."  A device attached to the system does not work.

  Help...

• Satellite U300-152 - no audio output device is installed

  The sounds are works well when I do update windows, update antivirus and updated some software like adobe air and adobe shockwave but when I open the laptop the next morning, there is a red cross marked in the speaker icon on the lower right of the laptop and it says : "no audio output device is installed".

  I couldn't find the sound and game controller in Device Manager so I'm frustrated. Its been 3 days now, I use the laptop without noise.

  Can you please help me in this matter?

  My laptop is Toshiba Satellite U300-152
  Windows 7 Ultimate but not pre-installed (Vista Home has been the pre-installed)

  I tried to download the latest audio driver from realtek high defintion, but its still does not. Tried several restarts, System Restore, disable antivirus but does not yet.

  I don't know what can be the problem but the fact is that updates Windows update offers some drivers and, in general, you should not install their Mr. with other words, you should only use the drivers from Toshiba.

  What can you do now? Have you tried to reduce the OS to an earlier time (before installing updates) and check the functionality?

  One last thing. Software driver Sound should start with Windows, then please check MSCONFIG > startup if the sound software is listed and enabled it.

• Satellite T130 - 11 H - NO Audio output device is installed

  I brought this new * Toshiba T130 - 11 H Satellite * (Windows7 / x 64) last week and at first, it was fine...

  Although I now have the speaker icon formidable with a RED CROSS in the lower right of the screen!
  It's become such a pain now - ive never had a problem with the sound with one of the laptops ive had.
  The message error is always 'no Audio output device is installed."

  I have tried everything - system restore, reinstall everything, download different drivers... Pray!
  When going to the Control Panel/Device Manager / sound, video and game controllers - I do not see the:

  Intel(r) High Definition Audio HDMI

  I remember when I got it I got an another "HD Audio Device" in this category - it is the one which has totally gone now and is quite important what I do:

  Please PLEASE please can someone help!
  Is it a hardware failure?
  Is there something I need to download?
  Is there something special I need to

  Will be grateful for any comments. Thank you so so so much to read :)

  Hello

  Go to the Device Manager and in order to choose the hidden devices.
  Now you should see all the devices that are available on this system.

  Now go to the sound, video and game controllers and remove the Intel(r) High Definition Audio HDMI, audio Conexant high definition Smart, etc.

  In system devices, remove the Microsoft UAA Bus driver for high definition.

  Now, restart the laptop.

  After the new operating system reboot Windows should recognize all devices again.
  Check this box!

  If this does not download the Conexant audio driver and reinstall

• Where can I download an Equium A100 PSAAQ Audio output device?

  I accidentally disabled the audio device on my computer (thinking I would get the option to activate it again...) and now I have no audio output device so there is no sound.
  It's REALLY frustrating me!

  Does anyone know where I can download one or how can I get my sound back?
  I tried to download an audio device on this site, but it has not made a difference. heeeeeeeeeeeeeeeeelp!

  Thanks :)

  Can I ask you how have you disabled the output device Audio (I guess you mean the sound card)?

  Usually the devices can be enabled or disabled in Device Manager.
  Please access the Device Manager in the control panel and check if there is a yellow exclamation point. There is perhaps no yellow exclamation point, but the sound card is still disabled. Then mark it and activate it.

• "No Audio output device is installed" on Portege M600

  Hi all

  I had this problem. Today in the afternoon, I was working with my M600 while listening to music. Suddenly, there's like a voice of vibrations... as "zzzz" voice. I was surprissed and decided to cut my music player (I use winamp) and continued complete my work. But, whenever I did by clicking on, this noise appeared with 'click' sound. So, I decided to turn off the PC.

  But now, I surprised because when I turn on my PC, there is "No Audio output device is installed" msg with the sign of the Red Cross on my speakers. I do not anything for the sound before. I have not installed anything. I have day my anti-virus, but that's all.
  This is not the first time happened. I had - a little - this problems twice but it was because I had windows update and I solved it by restoring the system.

  I did system restore, but it still won't work. I really need a help, since sound is so important to me!

  Have idea what had happened and how to handle this?

  Thank you in advance.

  Putri

  Have you tried to install a new sound card driver?
  You can find this driver on the Toshiba site:
  http://EU.computers.Toshiba-Europe.com

  Of course, it could also be a hardware problem with your motherboard and/or the sound chip but try first to update the driver.

  The sounds you describe could also be a HARD drive problem.
  Look in the event viewer for errors.

• Portege M100 - no audio output device

  I recently acquired a Portege M100 1.2 ghz model no PPM1DE-0000Y-EN. The hard drive had been cleaned, so I installed Windows XP with Service Pack 3. I don't have a utility Toshiba and driver CD.

  For the moment, my main problem is that there is no sound and I get messages of "no audio output device. I can watch a DVD but once again his silence as the internal speakers do not work. I am a novice, so if you have any tips please try to not do not technical but in simple terms that I can understand. There are probably a number of questions that I haven't discovered yet IE Power Saver, etc. without wire.

  I think you're missing the SOUNDMAX program to render sounds. At least that's what I had with my M200, but apparently M100 and M200 are quite similar. Installed SOUNDMAX SE will solve the problem. The easiest way is probably to get a sort of utility CD.

  And it's probably the only one too. Even if make you it work without, you always end up without the other Toshiba Utilities (which can be quite crucial, as power saving, ability to use the buttons and the FN keys, possibility to use the touchpad, etc..).
