# Why is my oscillogram of a simulated multivibrator wrong?

It there!

I'm trying to simulate a multivibrator using NAND-element, a capacity and resistance. The waveform of the signal caught in the blink of an eye between resistance and capacity is correct, than those between the two NANDs and resistance, but also between second nand and the ability are more discreet.

What I am doing wrong? Something as simple as a multivibrator should be easily possible to simulate.

Dear johannes,

Channel B and D are showing the out put the tensions of the first and second door NAND output voltages. These are output TTL voltages standard they will be 0 or 5 volts (different levels). If they output voltage like channel c where do you take the astable vibrator multi out put? mode itself astable multivibrator is a square wave generator, don't it?

Maybe you are confused with the currents and voltages. The current waveforms at these points show the exponential load currents. To see current forms wave connect the probe current as indicated in the attachment.

Concerning

Chaitanya has.

• Problem of Simulation multivibrator

Hello

I'm trying to simulate a simple multivibrator which I intend to use it to generate a square wave. I use this circuit:

I think that there is no problem with this circuit. Almost everywhere, I found this structure.

In virtually, the tour starts to work because of differences in the elements. Circuit was symmetrical, he started working in the simulation. To work around this problem, I tried to:

* Initailze one of the capacitor

Change of values of transistors Bf

* Take one of them as 2N2222A and other BC107

* Connect a picewise voltage source linear to transmit a transistor turned out (such as the creation of a) of pulse

But none of them worked.

Some of them seems to be working. But the output signal is very different from the square wave.  (Similar to a square wave noise )

How can I solve this problem?

Thank you very much

Try this in Multisim 10. Your collector resistances are far too high in the resistance. You must also select 'Set zero' for the initial conditions and integration "Gear" in the options analysis. You can add your own PB and LED.

• Why is - this vi gives the result of wrong time?

I have a NI 9401 and I found this example, using Labview 2011, I understand should measure the pulse width.  I have a photo with transistor output sensor that displays 12mVDC in the low State, and ~ 3700mVDC to a high State.  When I run this vi, (I added the WHILE loop to the original example) and I use my photo sensor manually, which means that there are hundreds of ms between rising or falling edges, the output is of a few microseconds?  Why t - he display such a short pulse width? I use cDAQ 9174.  I'd wait the time difference between the successive rising or falling edges to be in the hundreds of ms, not microseconds.

• Webworks Blackberry application does not not remote page on Simulator

My application Blackberry Webworks a problem opening a remote page when testing it in a Blackberry Simulator (I tried Verizon 9630, 9700-ATT, 9860-Asia). Whenever I try to open a remote page in my application webworks, the application crashes, and after a while, I get a white screen with the error error 104 Eception App: InterruptedIOException and when I click on continue a dialog message box comes up with the message Local connection timed out after ~ 120000. If I open this URL in the browser of the Simulator, it opens right away. What I don't know, this is why it does not open in the webworks app.

Now the funny part is, if I load the same webworks app in my blackberry device, it works perfectly. It opens the remote page immediately. I don't know why its not working in a simulator.

I have the config.xml file properly configured with the remote url defined in the element of access:

```http://sample-remote-server.com/" subdomains="true" />
```

I will be very happy if someone can spare their time to help me.

How to make the MDS?

If you are using eclipse, see this thread:

http://supportforums.BlackBerry.com/T5/Web-and-WebWorks-development/cannot-connect-to-Internet/TD-p/...

But if you don't use eclipse or just command-line bbwp, try to find the mds file in your path of Blackberry Webworks (usually in \Program Files\Research in Motion\BlackBerry Widget Packager\mds),

After searching for the folder, find the run.bat file, then run it.

• BrowserPlugin works Simulator, but the device does not recognize the mime type

Hello world

Use the BrowserPlugin class in JDE samples, I was able to record a personalized with my BlackBerry mime type. When the browser makes a redirect to a specific page with the mimetype, the browser will recognize and use getBrowserContent() to move my application to the foreground, above the BlackBerry browser.

I have this working on the Simulator, but on the device, I get the message: "unable to display the selected item. You want to save the item? »

When I click 'No', I get the message: "Unsupported media type: application/x-vnd.rim.xxxtest.

Like I said before, it works on the Simulator. I supported by the web server mime type, and I created a library project that will run at startup that will record the mime with the device type.

I've debugged on my real device and confirmed that my library project is actually the launch...

Someone know why this might work on the Simulator, but not on the device?

Ah,.

I'm embarrassed. I had unconsciously assume that when I used Javaloader to load my application to my phone that it would also include the referenced library projects... I was wrong!

I loaded the library project separately and it works very well.

• MAF: Applications deployed on iOS Simulator are not visible

Hello

I use Jdeveloper 12.1.3 for the implementation of the MAF on MAC device. I used to use Jdev 11.1.2.4 with Xcode 5.1.1 and jdk 1.6. Now, after the release of the CRG, I uninstalled Jdev 11.1.2.4, jdk 1.6 and installed Jdev 12.1.3 and jdk 1.7. Open examples of good applications that created new application also. But when it is deployed to the iOS Simulator, it gets deployed successfully but in the Simulator, no icons appear for applications. Pointers please.

Thank you

• Why are the rotation buttons upside autour

Why are the rotation of the knobs the wrong way autour.

It allows to be that we could move the buttons of the icon freely, but now we are forced to put them as chosen by Adobe.

The problem is that Adobe is American and we know all that the Americans do things the wrong way autour. :-)

So why does make sense to them than the Rotate counterclockwise button is on the right and the right-hand rotation button is left?

If you want to rotate a PDF anti-clockwise, then you choose the button anti-clockwise. It is a movement of the LEFT then why is the button counterclockwise on the right?

Hello

Thanks for your suggestion. If you use Acrobat DC we have options page under the tool rotation organize Pages (with the same icons) where changes can be saved, while, to discover rotation only tools that cannot be saved are opposite. It's just to make the difference between the two sets.

• Xcode is based, but does not work

Hi people,

I have a problem with Xcode

When I try to launch a project, it generates correctly and then just says "running < name >: < name >»

Some time previously, I have worked on some projects of iOS and at the time, everything worked fine.

Not even that, they run more.

I don't know why it stopped working in the simulator of the app is just a white screen.

Mac OS projects with cocoa does not even launch the built application. Console applications do not work or the other.

I had this behavior with XCode 7, then tried the beta version 8, which also had the problem.

This morning, I decided to uninstall XCode and reinstalled version 8 of XCode from the App Store.

The problem persists there.

IM under OSX 10.11.6 and Xcode Version 8.0 (8A218a).

Please help me, I'm getting desperate. I can't develop this way.

Best regards

I would check to see if there is a modal dialog box, asking you to authenticate before running your application:

• Avoid execution at startup of the device

Hi all

I'll try to be clear what is my problem.  I have a few heavy initialization (call to the web service among other things) on the manufacturer of the App codes.  When I debug Eclipse and the emulator starts, I see that this constructor is executed (for the emulator to start). I don't know if this code is executed on the device too when deploying the application, but I want to avoid this run at the start of the device.

Bruno.

Apps to run on install which is why you see it on the Simulator. It must not actually running on the device.

• Focus on the screen change

Hello

I have a question about the focus on the evolution of the screen:

If a button has the focus on A screen and the user presses on it, I have the screen B.

By pressing the back of screen B button, A screen is redisplayed no field does however seem to have the focus.  On the simulator of the door where you expect it to be (IE button) but on the real device, no field seems to have any home.

Edit: The reason why he's working on the Simulator is because I hit the return.  If I do that on the device (and not on the trackball Center), it works as well.  How could I make it work for both?

See you soon

Dave

Hello

I ended up finding it works by:

```    protected void onExposed()    {        setFocus();    }
```

On A screen, which did the trick.  Don't know where the emphasis would have been otherwise since screen B should have been even when popped, but it works :^)

My apologies if the question was obvious, I am new to BlackBerry.

See you soon,.

• Problem with PopupScreen on the device of BB storm

Any ideas as to what created it, and why it is not on the Simulator?

Thank you

Don't know the answer to the first question and I'm also interested to hear the answer.

But with regard to the second question: use

```protected void applyTheme()
{}
```

to override the theme (which draws the border around the popup).
