Playing audio from inside of a state machine without stopping execution

I created a state machine that acquires and analyzes the input signal and the state transitions based on triggers found in the breast of this signal.  In a particular State, I need to read a pre-recorded file (right now I'm just using a file .wav for testing purposes).  I understand that because of data flow model of the state machine hangs up during playback status until playback is complete, but I need to find a way around that.  Of course, whenever the machine hangs may not continue the acquisition and analysis of the signal.  How to start playback from the state machine without stopping its execution?

Do you use the his release screws? If you do, try this. On the 'Play Sound file VI' set timeout = 0

  • Windows 7 Media Center plays audio from VOB, no video. However, the VOB files play fine in Windows Media Player 7. What gives?

    I have VOB files in a VIDEO_TS folder.  Windows 7 Media Center will generate a thumbnail for them, but when I play them I'm audio but not video.  However, when I play in Windows Media Player will play without any problem.  Can someone help me solve this problem?

    Hello Pinkled,

    Just got out how we can get video of .vob files play correctly:

    It's pretty simple, just add the folder to the library of MOVIES instead of VIDEOS. It is true that videos, just listen to the audio, but no video appears during playback.
    Once you add to the movie library, W7 Media Center it will read "like a DVD" then you will also be able to navigate through menus.

    Hope that works for you also.

    Kind regards

  • Can not play audio from speaker - Help!

    I want to play a simple sound through the speaker and we have tried the following code:

  • How can I get firefox version 36 to play audio from our program by default selected and not embedded quicktime player?

    In our environment of the room, staff prefer to have MP3s from various sources to download open directly in the window of the program from the outside (here Goldwave is the favorite program). That being said, with the new version (36 specifically) the behavior of the program has changed so that the MP3s are open in a browser tab separated, regardless of the preferences in the window "Applications" of Options and the default values of the program in Windows. Previous adjustments to about: config media.windows - media - foundation.enabled as well as media.directshow.enabled and the setting to 'False' is more to solve this problem.

  • Replacement of a state machine?

    I'm relatively new to the use of the State machines and hope that there is a simple solution to this issue. I have a registered state machine (IE StateMachine1.ctl). I created a new machine of the State (StateMachine2.ctl) and you want to replace all instances of StateMachine1 by StateMachine2 in my VI. Is there a simple way to change the state machine without losing all linked instances?

    Thank you.

    LWolfe.

    I remember doing a VI to find instances of a type def control and the replacement by another.  Very similar to what you describe.  He used script and it was surprisingly hard to do.  Oh, and I managed to find it.

  • Audio from Mail will not play on the lock since 9.2 screen!

    This is verified a discussion with an expert on the AppleCare, last night and it of a real disappointment for me and people like me who get a lot of attachments audio (mp3 etc) and should consult with them on the go. Used to be that if you open an audio file as an attachment to an email in Mail (up to iOS 9.1) and start playing, then lock your screen, the audio continues to play without interruption, and more you can use the commands to switch the lock on that screen the sound signal. Now, when you lock your screen in iOS 9.2, the sound just stops! Yay for promotion! In addition, when you switch from mail to say, Safari, the sound stops too. Apparently the iOS does not recognize Mail as a background audio source. It is a GREAT DISAPPOINTMENT and really needs to be fixed as soon as POSSIBLE.

    Anyway, just to say that if you rely on this feature, please do not update to 9.2. I really wish I didn't.

    Thank you for the HRT, thought it was just me. Even disbarred icloud drive because of this, but now I see that apple really messed that one up.

  • Closure of a state machine in queue event with several parallel loops

    I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

    I look forward to any comments on my as well code, if someone is willing to offer it.

    My program needs:

    If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

    Architectural details:

    The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

    During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

    In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

    HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

    I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

    I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

    Thank you!

    First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

  • PID state machine problem

    Hello.

    I have a problem with my design of State machine and I need help to know what to do.

    I m using a state machine six steps for HVAC test machines. Password-> Idle it down-> Run-> Acquire-> Report--> Shut. Run and acquire the States have PID controls in them (almost identical States) and very fast three-way-valves they´re for the desired control of the temperatures of the water mixture. I m running try to get static values for temperatures and I m satisfied with them, moving to acquire the State to get the data in the report. My problem is that when the race to acquire, PID control outputs from scratch and at that time there static temperatures have disappeared. Worst case is that the tested machine HVAC stops following liquids from bad weather and I start from the beginning.

    Is there a way to tell the PID.vi the release of starting a specific value? In this case, continue to the last value that they released in the State of enforcement?

    I know that scheluding of gain would do (machines would be not closed) but I Don t want to use it because the original problem would still be there.

    Arctic_Fox wrote:

    So PID vi:s remove from the state machine, placing them inside the while loop that surrounds the state machine and leaving all necessary writing DAQmx-functions inside the race and the States Acquire would make corrections on the positions of the valve only on those two States. Right?

    It is a good idea.  I leave the DAQmx functions outside the state machine as well.  If you need to write a fixed value for the outputs when the PID is not running, use the PID that you already have to determine the value to write (output PID or anything else) on/off switch.  In addition, I would make sure the reset of PID entry is true whenever the PID is not running.

  • creation of structures: state machine with controls

    Hello, I wonder if someone can help me with something. I have a sequence, followed by the event structure / while loop.

    someone can help me. I want to create a STATE MACHINE.

    Here's a basic outline of the current structure, I. and this is what I want it to be. I wonder if its possible and how.

    I'm using labview 7.0.

    Thank you

    This is what I want?

    I looked at your Executive VI.  I don't have an easy way to save in LV 7 now so I'll try to describe in words how I would approach this mess.

    I think it can be done with two loops, a structure of the event, a case structure and not global or local variables.  In fact, there is probably some small business structures and lines inside some of the case, but nothing like as layers of ~ 12 nesting, you're struggling now.

    Look at the design model of producer/consumer (events) as a starting point.

    The loop of producer (event loop) will have the structure of the event.  It will be a case for each control that requires immediate action.  Those that I could identify: get telemetry, side, open Journal printing, abandon, press tank Mode (?) Temp tank (?), Scan, Stop, wait, Step (?) unique, continue and Execute. Most of the buttons must be set on the mechanical action of locking and placed terminals in the case of the event appropriate. So no local population is necessary to reset them.  Those with (?) have no event.  You can have a case of timeout to display Date and time, eliminating which (painful to my eyes) loop.  I don't know about the other stuff in the case of a timeout, but most likely, it is up to the other loop.  If the room 1, 2,... buttons change during trips, they may also need event.  Inside of each event is exactly one element: the Enqueue function.  Create an enum command and make it a typedef. Enqueue this enum value. The queue will be read in the loop of consumer where all the action happens.

    The consumer is your state machine. It has a Dequeue function to get a new order for the structure of the event.  It has several shift registers to transfer data from one case to the other.  These removes your global and local variables.  I'd shift for each of the following registers: the State (typedef enum), cluster of error, temperature (table), pressure (table), results (table), Stat results (table grapes) and a big cluster Indicators_Flags (typedef).  The cluster Indicators_Flags everything that is in the cluster you initialize in the black image sequence (and then never reuse) would have more all indicators except the berries in Maj separate records as well as all your globals and no status indicator, you might need.

    The structure of matter is the heart of the state machine.  All shift registers through it.  It will be the case for what the program does.  Everything in this black initialization setting in about 15 cases of Init.  The while loop to the right of the boot image goes away, but the case inside to become some of the cases of the state machine.  Chassis temperature cycling code goes into 1-3 cases. Mode code pump and read the pressure of your case of timeout event are 1-3 cases.  Code of telemetry: 2 cases.  Print the Page before: 1 case.  Excel code.  Abandonment of code.  Temperature and pressure cycling code of main program: 5-20 cases.  Graphics, record in file: more cases.  Break: 1-2 cases.

    I would like to make a list on paper anyway, you think that you may need and allows to create a typedef enum to control cases.  By making a typedef, it is easy to change without running all over the code looking for the constant in all cases of change.  Enum names will appear on the structure of matter as strings.  Create the loop, shift registers and the structure of the case.  Moving is part of both the original thread can duplicate the case until you have a case for each value in the enumeration of the State.  (Do not use the case of the mark for each value option because it will empty cases that you will then need to wire through.)

    Then copy code from various places in your existing code in the case in the new VI.  Try to avoid copying inhabitants that it will create new controls.  Name bundle to get data in and out of the big bend cluster registry and use ungroup by name.  This provides a free documentation of the data used.

    Check in a month when you have other problems. This will not be a quick fix.  But it will be useful to have a program that works and is easy to manage.

  • Captivate 8 - "Audio" in the context of a fast action is not playing audio

    Hello. I was hoping you could help me, because I can't understand why what I'm doing doesn't work.

    I have a slide where I explain the answers to a game earlier in the captivate. Each question is a hyperlink that runs a tip action. This action is currently a set group of objects (box highlight to hide the rest of the screen) and two boxes with text captions. From the top of each box has a red X that I use as a button. Clicking this button launches a tip action that hides everything simply all these objects.

    The screen without a caption box:

    Screen.png

    The screen with a caption box:

    Screen w caption box.png

    My calendar:

    Timeline.png

    I try to add audio to the text explanations, but cannot get the sound to play. I edited stocks advanced for hyperlinks read 'H1 Show' (objects grouped for that matter) in the first line and "Play audio H1.wav" in the second line. I also changed the advanced actions related to the red Xs 'Hide H1' and 'Audio triggered Stop. "

    advanced action 1.png

    advanced action 2.png

    Unfortunately, when I do that, the sound does not play. My limited knowledge of captivate, update the advanced actions on what you see above should cause an audio file specific to play when they click the hyperlink and the beep to stop when you click on the red X. Currently, the audio does not play.

    Does anyone know what I have neglected to make it work correctly?

    Thanks a lot for the answers.

    It must indeed work, don't have time to test and do not immediately see the problem.

    However, would it not easier to fix this audio clip text in the Hx group? He will play only when the group is displayed.

    Update: I tested this out in Captivate 9, with the example, I created for the blog: play with Captivate 9 - Captivate blog

    It works perfectly for me: I added an order of audio playback to the joint action, I used to show the lightbox and stop triggered audio to the action of the close button.

    I have test browser both browser HTML to check if it works for output SWF and HTML. For such an order, that I never had the experience that I should have to publish to make it work, maybe I'm lucky.

    It's common action, I used to change the State instead of display Lightbox, the Show action is for the close button.

    For the close button:

    Sorry that I could not test it on 8.

  • MBA does not play audio on JBL EXTREME

    Hello

    I tried to play music on my new JBL EXTREME of blue tooth speaker that proved no problem on my phone I have 6 s +.

    However, I can't be able to remove from my Mac Book Air!

    It's 'pairs' very well with the JBL speaker sound!

    He has played from the loudspeakers of the MBA.

    No music, no audio from Youtube on the JBL; nothing!

    I run the latest version of the software, and I restarted the MBA and the JBL repeatedly.

    My MBA plays very well with my Sennheiser Blue Tooth headset, so I think that my audio settings are OK. (?)

    Someone has an idea of what the question might be, please?

    Thank you!

    If you're able to pair your bluetooth with your Mac speaker, but your Mac continues to stream audio from its built-in speakers, you might check to see which device is selected in now Option while you click on the Volume control () in your menu bar. You can also check in system preferences > Sound > output.

    OS X El Capitan: adjust the audio output of your computer settings

    Note If you don't see the Volume control () in the menu bar, you can add it by checking the box "Show volume in menu bar" in system preferences > Sound.
