How to synchronize with RTSI?

Hi all
I am working with 2 PCIe card (#6351 and #6536) connected via RTSI. The bus RTSI permit to solve 2 critical problems in my application: simultaneous triggering and synchronization
For the synchronization, I would like to generate a rectangular signal with a fixed low level (5 microseconds) and a high level that I can tune with the card 6351 on the RTSI line 0
For the simultaneous triggering, RTSI line 1 is at 0 (low level) by default. The acquisition and the emission of the synchronization signal is triggered on a rising edge.
Here is the chronogram of the signals RTSI lines 0 and 1:
a) acquisition starts
b) 5 microseconds
c) measuring something
d) refreshing all the digital outputs
e) end
Could you help me with the vi because I really do not know how to proceed
Thanks by advance

I've programmed a bit of FPGA, but not to the point where I'd call myself an expert with it. I understand everything going on in the attached FPGA vi and our primary FPGA vi (not attached).
I was hoping to implement it into the host because the desired frequency of the pulse from the daqmx counter has already been implemented in a much larger application, and it is actually a control on the front panel. Changing the location of the source would require rewriting a lot of code. 65536 Hz will be the fastest possible frequency so I went ahead and wired the worst case scenario into the attached vi. Also the desired frequency is approximately 65 kHz, not MHz.
I'd simply like to find a way to use the 65536 Hz pulse from /Dev1/Ctr0InternalOutput to run the FPGA subvi at every rising edge of the pulse if possible.
Thanks for your help!

How to synchronize animation with time?

I want to synchronize animation with time, but I can't determine the current time, because the return value of the System.currentTimeMillis() method is updated only every 10 milliseconds.
The following example demonstrates it:
import java.applet.Applet;
import java.awt.Graphics;
class TimeStep extends Applet
long minimalStep=1000L;
long lastTime=System.currentTimeMillis();
public void paint(Graphics g)
    g.drawString("Minimal timestep: "+minimalStep,5,30);
    for (int i=25;i-->0;)
      while (true)
         long newTime=System.currentTimeMillis();
         long step=newTime-lastTime;
         if (step>0L)
             if (step<minimalStep)
                minimalStep=step;
             lastTime=newTime;
             break;
    repaint();
}It causes flickers by most framerates:
import java.applet.Applet;
import java.awt.Graphics;
class SynchronizedAnimation extends Applet
static final int FRAME_RATE=90;     // 100 works, 90 flickers
static final int STEP=5;
static final int WIDTH=640;
static final int HEIGHT=20;
static final long FRAME_TIME=1000L/FRAME_RATE;
int lastPosition,newPosition;
long lastTime=System.currentTimeMillis();
public void paint(Graphics g)
    long waitedTime=lastTime+FRAME_TIME;
    while (waitedTime-System.currentTimeMillis()>0L);
    lastTime=waitedTime;
    newPosition=(lastPosition+STEP)%WIDTH;
    g.drawLine(newPosition,0,newPosition,HEIGHT);
    if (lastPosition!=newPosition)
        g.setColor(getBackground());
        g.drawLine(lastPosition,0,lastPosition,HEIGHT);
        lastPosition=newPosition;
    repaint(0L);
public void update(Graphics g)
    paint(g);

On windows 9x its even worse. The timer is only updated every 50/60 milliseconds.
Instead you could do something like keep the time when the animation starts, and then everytime you want to paint, check how much time has gone since then and calculate where the animation has gone to at this point.
Even if you can only update every 50 ms, it gives you 20 frames. I don't think its that bad.

How to synchronize itunes with the hard-drive's directories ?

Hi everyone,
I'm new at iTunes and iPod.
I'm used to put all my mp3 files in the same folder. I add every weeks some new mp3 files.
How to tell to iTunes to synchronize and get the new files in the music folder ?
In the same way, i try to refresh the ide3 tags from my mp3 files.
I use Tag&Rename software. But it seems that itunes doesn't xant to see the ide3 tags modifications ?
How to tell him to refresh in its own library the newly updated tags ?
thx for your answers

How to synchronize iPhone with iTunes in Mac and BootCamp.

Hi,
I have a Macbook Pro and recently I purchased an iPhone. For work reasons I use windows as well as Mac OS ( I prefeer MacOS by in my company we develop windows software...)
The problem is that I synchronized my iPhone with iTunes in Windows and I want to use my iPhone with Mac iTunes too.
I think a possible solution is to use the same library in the two OS, and I don't know if it is possible.
In Mac OS I don't have write access to BootCamp's NTFS file-system partition, so I use a Windows software to full acces to Mac OS partition. For me the solution would be to place windows iTunes library files in MacOS partition and use these files with MacOS iTunes as library too, but I don't know if it's possible.
If anyone have any other idea how to solve this problem...
Thanks,
Raul

All your contacts, photos, music etc. should be on your computer, so you just sync the second iPhone to the same computer as the first iPhone.

How to synchronize iPad with an existing iTunes Library

Hye to all,
I've got the following issue (strage to a new Apple user having Windows backgroud):
after reinstallation my Win7 PC (only System Partition updated) the old iTunes Library (stored on my Data Partition) and automatically created by previously connecting my iPad to the PC is not longer recognized any.
I've tried the trick to start iTunes with the SHIFT key pushed simultaneously, but seems like iTunes really wants to delete my iPad content in order to do the synchronization. I do not really understand this behaviour since the iTunes Library ist untouched at all by the Win7 installation.
Can somebody give me a piece of advice regarding this issue?
Thx in advance for any help!

How to Synchronization Outlook with third party system?

Our Customer has a website which has a table by name task. This task table on the website is populated by admin of the website. Each
task is assigned to sales person. The Customer wants the website task to be synchronized with
outlook task for each sales person.
What we have already done
We have already created a table and pages on the website. Allowing
Admin user to create/edit/delete
task on the website.
We have created a web service that pulls and pushes data from the website's
task table by sales person.
We have added a "Synch" button in the sales person's outlook.
On click of the "Synch" button we make a call to the
web service
and the synch between outlook task and website is done. I.E. task are
created/updated in outlook, closed task marked in outlook are closed on
the website.
What I am unable to figure out
We do not want sales person to click the Synch button after every few
minutes, so we want outlook to call our process periodically, just like
send-receive in outlook. However I am unable to find a hook provided by
outlook to call a process periodically.
How can we do this?
Thanks
Anand

1. Use DRM Export to Table option, for that create an External Connection first for the Target Database and select the respective Tables to which you wish to Export the Hierarchy information.
2. You can perform most of the DRM Actions via the DRM_BATCH_CLIENT.exe.
Please refer to Using the Data Relationship Management Batch Client of DRM User guide.
let me know if you have any issues.

How to synchronize wf_roles with fnd_users

good day,
Is there any concurrent programs to synchronize fnd_users or per_people_x users with wf_roles, or wf_local_roles.
thanks

The job synchronizes FND Users with the Workflow directory service (plus any other systems you specify). PER is a special case, and will only be synchronized with the Workflow directory service if they are associated with a user - otherwise the records are not included. If they have corresponding HZ_PARTY records, then these may be synchronized, but should not really be used for notifications, since there is no login mechanism for the users to view the notification sent to a party record.
HTH,
Matt

How to synchronize colors with two different video cameras

I own Sony FX1 and HC9 video cameras. The color between the two video cameras can be pretty noticeable, and I tend to flip between the two cameras a lot during editing. Ideally I would get them to match up better before I start filming, but despite my attempts, I still can see a noticeable difference between them in post-production. I know I can use the color corrector filter to adjust the colors, but is there a more effective way to adjust the colors of the two video so they match better? I have used that eyedropper on the "visual" screen of the color corrector to adjust the white balance. Is there something similar where I could for example click the eyedropper on the blue of one video and it would change the blue of the video from the second camera to match?

You don't really have the controls for that in FCE. You can't fine tune the color with real precision for color matching in FCE. There is a match hue function with the eyedropper, but without separate shadows, mids, and highlight color controls there is only so much you can do.

Synchronize form with self-referencing VO in tree table. POJO Based Model

Hello. I need your help
ADF Code Corner sample #32 show how to build a tree table from a self referencing VO:
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples]
ADF Code Corner document Oracle JDeveloper OTN Harvest 09/2011 by Frank Nimphius show how to build an edit form for the table data and how to synchronize it with the selected row in the tree table:
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/sept2011-otn-harvest-508189.pdf]
This examples are helpful, but i have a problem, i have not a model based on a database, my application datamodel is based in POJO objects, there are no appModules or ViewObjects so I do not know how to reference the tree table target attribute with the edit form iterator.
Can anyone help me?
Maybe (i dont know how) i need make a VO and a AppModule that wraps the POJO model ?
thank you very much

Hi,
this should work the same. You create a tree from a POJO Data Control based on your POJO Model. Expose another collection pointing to the same data set and drag it as the form. Use the setting on the tree configuration dialog to set the current row in the tree as the current in the form iterator.

How to sync iTunes with iPad I am not getting any options in iPad except iTunes U and Podcasts

How to synchronize iPad with iTunes with new apple Id .I'm getting no options in
iTunes and App Store and in iTunes as well no options are being seen except ITunes U and Podcast .

Currently Pakistan only has apps, podcasts, iTunes U and free ibooks, so you won't see music, films and TV shows - if/when they will be available there will depend upon when the content providers allow Apple to sell their content.
For music are there other music purchase download sites that you have access to ? If you do, and they are in a compatible format, then you should be able to add them to your computer's iTunes library via File > Add To Library and you can then sync them to your iPad. You can also copy your own CDs via your computer's iTunes

How to synchronize a graphic on one layer with an effect on another

Hi. I'd like to use the bulge effect on my main layer to create distortions in the underlying graphic. I'd also like to synchronize this with the image of a magnifying glass or other lens so that when I mover the lens around, the main image distorts / bulges beneath it. Not sure if I should place the magnifying glass on its own layer (or the same layer as the main image). Also not sure how to go about parenting an effect (like bulge) to an object / image (like a magnifying glass).
Any help would be appreciated.
Thanks

Thanks for providing the link.
As to the Search function, I usually do try to search first because I understand these forums are pretty much run by volunteers who are giving freely of their time and expertise. That said, I rarely find what I need. Probably has to do with how the info is indexed, plus my overall lack of familiarity with After Effects at this point. For instance, I just tried putting in "linking a layer to an effect on another layer" or something like that. That pulled up a list of 20 or so items. There were a couple of links to Expressions, and that probably would have tipped me off to the right answer.
Anyway, I appreciate the link you provided, and I'll try to work on my searches.
