Can I trigger the read of a buffer period measurement with a external signal (PFI line) with my 6602 card? How can I do it?

I am doing a buffered period measurement with a 6602 card, Labview real time. I want to measure the period of 6 rising edges of a TTL, but I want to do it exactly when an edge comes on other external signal (of course slowler than the previous one), that is to say that I want an external start trigger. Can anybody help me? I have hardly searched at the web and I have not found an example of code of what I am looking for.
Another question:
After reading the buffer, how does my program know that the data has been refreshed in a continuous measurement? I attach two VIs I am trying to make work and a quite explanatory bmp of what I
want to do.
Thanks.

Hello;
I can't think of any way to accomplish that task. Once the counters have only two input pins, and both are in use when one configures the counter to do buffered measurements, there isn't a way to trigger that operation in hardware.
I'm not sure if I understood your second question, however, the buffered operation on a counter is hardware controlled, meaning that a pulse on its gate input triggers the transfer of the count value from the counter register to the PC memory buffer. That is therefore a continuous measurement.

I can't play the downloaded iTunes movie on my newly updated iMac to OS X Maverick. Why not? And How can I get it to work? Thanks.

Do you get any error message?
What actually happens when you open it?
What app are you trying to play the files inside? Try iTunes.
I assume these files have DRM from the iTunes store. The Mac needs to be authorized to play them, open iTunes & select Authorize in the store menu, then sign in with the Apple ID that purchased the files.
Select the iTem in iTunes & get info on it (from the File menu) & you can see the account name that it belongs to.

My old itunes id was an email that no longer can be used, therefore, I can not change the password for that account. Everything that I purchased under that id name will not play. How can I fix this?

I no longer have an email address that was also my Apple ID. Can I still use the email address as my Apple ID?
Apple recommends you change your Apple ID to your current, working email address. This will not create another Apple ID, it will only change it to your working email address. See Changing the name you use for your Apple ID if you'd like more information.
Note: @mac.com and @me.com Apple IDs can not be renamed. If you no longer use the .mac or .me email address be sure to add your valid email address as an additional email address.

I have several questions. First one, how can I change the email address on my icloud to match my itunes?, I have several questions. First one, how can I change the email address on my icloud to match my itunes?

The email address I have now is not the email I had when I set up my icloud and now I can't update the new email address on my iphone, can someone help me?
Second question, I didn't know that everyone in the house had to have a separate itunes account so now my oldest information is on my iphone now, not mine. I have lost all my contacts, notes and everything and all the information from my oldest is now on the icloud not mine. How do I get my information back on my iphone?

If you need to change the primary email address associated with your iCloud Apple ID, see "How to change you Apple ID and primary email address" here: http://support.apple.com/kb/HE68. If you change the name of your ID you will need to go to Settings>iCloud on your phone and tap Delete Account, then sign back in with your new credentials. Deleting the account will only delete the account and your synced data from your phone, not from iCloud. Provided you are signing back into the same account and not changing accounts, you data will be synced back to your phone when you sign back in. If you have any photo stream photos on your phone that are over 30 days old, save them to the camera roll before deleting the account (open your my photo stream album, tap Edit, tap the photos, tap Share, tap Save to Camera Roll).
On your second question, did you change iCloud accounts and lose all your data? If so, is your data still in the original account when you sign into it and check from a computer?

Where can I download the first guitar lesson. It is supposed to come preinstalled but I don't have it. How can I get it?

One of the reasons I upgraded to GarageBand 11 was that I wanted to use the tutorials and the free lessons. But although I've been able to download all the free tutorials, I am missing the first one that is supposed to come preinstalled. Can somebody tell me where or how can I get the "Intro to guitar lesson" that I am missing?

I have this problem as well. All the other lessons are there, but not the first one. I see 5 or 6 threads here about this but no replies. What's the deal?

Can not trigger the null event!

Page newPage = new Page("ListAffirmSubmit_Java");
EventResult result = new EventResult(newPage);
return result;
This way can not trigger the null event in the 'newPage'.I want to call the null event to init the viewobject in the 'newPage'.
Can you tell me the reason or another way to init it?

I have found a way from the help on line:
Page nextPage = new Page("ListAffirmSubmit_Java");
Page redirectPage = RedirectUtils.getRedirectPage(context, nextPage);
return new EventResult(redirectPage);

PCI-6254 DIO Read - Need to know how to trigger the Read operation??

Hi,
Can anyone help me with DIO Read operation using PCI-6254 (DAQmx)??
here'e the breakdown of the issue i'm having:
i'm doing a DIO Read using DAQmx drivers, and am using "one channel for each line" on the Port 0.
i'm using another line for DIO Write at the same time...infact the DIO write sends the bit pattern
and inturn triggers an external device, and am trying to capture the response of ext. device on
other line thro' DIO READ...
now, i do see the bit pattern on the Oscope, but am not reading the bit pattern using DAQmx Read?
(i'm reading all ZEROS)
Currently, i'm not using DAQmx Trigger? i tried using it, but was getting an error...
i guess i need to trigger the read when the line goes high/low (for ex)
can anyone help me with this?
Regards,
rkpat

Hi rkphat,
DIO operations on an M Series device cannot be configured for triggers. The source of the DIO sample clock must be set up for the trigger and the DIO operation should just be configured to receive that clock. You must provide an external clock or a clock generated by another subsystem, such as an analog input sample clock or a counter pulse train output, to clock digital operations. For example, if you were going to use the analog input sample clock to clock your digital measurements, you would configure your AI subsystem to receive a start trigger and to use an internal clock. Once the trigger arrives, the AI Sample clock is generated and passed to the DIO subsystem. Or if you wanted to use a counter to generate the clock, you would set the counter up for pulse train generation with a digital start trigger.
If you post your code we can find out why the Digital Read is not returning the correct data.
Cheers,
Lesley Y.

How can I delete the reading list in Safari on iPad 2?

I would like to delete the reading list in Safari on my iPad 2. How do I have to do it?

You can't delete the reading list portion of the bookmarks window. It is built into the app so you can't delete it. That is not optional.
You can delete items from the reading list by swiping Across the item in the reading list to bring up a red Delete button. Then tap that button to delete the item from the list.

Only the carrier it is locked to can authorize unlocking it. Sounds like the phone was hacked to unlock it originally. Find out what carrier it is locked to, and look up their contact information using google or the search engine of your choice.

Can I hide the "read only" posts

Can I hide the "read only" posts? that always appear at the top of other threads because it's a pain having to scroll down past them each time to get to the normal threads.

If you make sure you're signed in whenever you visit the forums, each thread on a board will show the number of new posts since the last time you visited the thread. If you then click on that number you will be taken straight to the first of the unread posts. For example this from the BB Speed/Connection board shows eight new posts since I last looked at the thread; clicking the figure 8 goes to the first of them.

In Yosemite, How can I get the "READER" button back in the Tool Bar at the top of the screen

In OS X Yosemite,
How can I get the "READER" button back in the Tool Bar for Safari at the top of the screen ?
Thanks,

I don't see the "READER button".
I see "READ LATER" but not the "READER" function.
Maybe I'm doing it wrong.
Please continue to HELP ME with this question.
In the previous version of Safari, there was a "READER Button" on the right side of the tool bar. This brings up the selected web page in a READER mode all by itself, without the ads, etc.
Are you saying that I can get this function by clicking on the Left side of the Address bar?
When I do that, I get lots of icons, but NOT the READER button.
Thanks

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

My mac won't read my external harddrive's videos that I took with my Nikon. Half the videos won't play, and those are .avi files. WHY won't they play anymore and how can i retrieve them?

What exactly is your problem? Is it, (a) your Mac doesn't read your external disk, or, (b) you can't retrieve your videos, or, (c) you can't play them, or, (d) you were able to play them at one point, but not any more.
What version of Mac OS X are you using, what app are you trying to play your videos with, what happens when you do, and what error messages, if any, do you get?
