I'd like to know how I can acquire a waveform on a loop and do a circular buffer with this waveforms I will acquire, cause I want to reduce the noise.

I'm using trigger for this data acquisition.

deco,
If you really want a circular buffer, how much data do you want it to hold? One acquisition? Two? Three? Once this is decided, you will need to create the waveform and then continuously strip the old data out and place the new data in. This will add a bit of overhead to your VI.
There are also software noise filters in LabVIEW that you can use to reduce the noise in your signal.
Lastly, if there is a lot of noise, you may want to consider an SCXI system which will filter out most of the noise as the data is being acquired.

No. The attached is the simplest way of modifying it to do as you want. I've
sped things up a little to make it obvious.

You already are. You're making the arrays as you go along so only the memory
needed for the data that's in the plot is in use at any one time. To do it
without storing
arrays at all you'd need to keep retrieving the data from
the XYgraph, adding the new datapoint and writing it back. Messy and I
suspect incredibly inefficient.
You're going to use the memory in any case- a better option would be to
pre-initialise an array and fill it slowly. At the end of each 24 hour block
zap all the data and start again without destroying and recreating the
arrays. Or if you're only doing the 24 hour wipes to save memory, simply
start again at the start of the buffer woithout erasing the previous data
and you always have 24 hours of data to liik at once the system's running.
Do a search for keywords like "pre initialise" or "circular buffer" on
ni.com

Here's a quick example I threw together that generates a sort-of-bell-curve shaped data distribution, then performs the binning and plotting.

Before I updated my iPod I had all of the songs to an album that I bought on iTunes. After I updated my iPod I only have 5 of those songs from the album. I would like to know how I can get the rest of the songs cause I already paid for the album and I went on my computer and it said that I have to pay for them even though I already paid for the whole album. So what do I do?

Sync with the same computer iTunes that you normally sync with.

Regardless, it is not a matter of carrier locking. Verizon iPhone 5 phones were never GSM sim-locked to begin with. Every iPhone Verizon has sold since the introduction of the iPhone 5 has been sold with an unlocked GSM slot, as required in the USA by their agreement with the FCC. They have not been allowed to sell any iPhone 5, iPhone 5c nor iPhone 5s devices with GSM carrier locking in place.
Your connection problems are from some other cause - it is NOT a carrier locking issue.

Log in on iCloud.com and go to Mail. In Mail, at the bottom left you should see a gear icon. Click on it, go to Settings (or Preferences, I'm doing this from memory), and in there you'll find an option to forward your iCloud email to another service.

Hi Michael,
Download Coconut battery, its a smal program that displays battery information and if you have over 500 battery load cycles it might be nearly ready to be replaced. I had to do the exact same thing.
When the battery gets close to dying it starts to lose the macs PRAM and NVRAM settings possibly eventually stopping you from selecting a boot disk or it might even just randomly freeze and require a restart. If this does happen hold down Command+alt+P+R to reset these parameters on reboot before the grey screen appears.
If this starts to happen you know it needs replacing
Good luck

I have put epubs into ibooks and i would like to know how i can then export them to an email or dropbox?

I have put epubs into ibooks and i would like to know how i can then export them to an email or dropbox?

You will have to go via your computer's iTunes. Connect the iPad to your computer's iTunes and do File > Devices > Transfer Purchases in iTunes (that should copy epubs and/or PDFs that are in the iBooks app, not just actual ibooks), and if using a Mac with Mavericks or Yosemite on it then do File > Move Books From iTunes in its iBooks app. You can then email them or add them to Dropbox from your computer.

TS2755 I would like to know how I can save a years worth of text messages from my iphone 4s to my computer. (I have verizon as a carrier)

Hey:
Hi everyone.
would like to know how I can save a years worth of text messages from my iphone 4s to my computer.
(I have Verizon Wireless as a carrier), I have tried the app store but it is okay for one messgae but not for hundreds.
Can you help me.
Thank you in advance. Happy Thanks Giving.

There is no Apple provided way to save text messages to a computer.
The iPhone backup done via iTunes or iCloud, will backup the messages but they are not accessible on the computer.
A google search may reveal options to saving the messages to the computer.

I have had to delete my icloud account and open up another because it would not verify. In the meantime I have lost my storage which was attached to the previous email account. I would like to know how I can transfer it across to my existing account?

Thanks randers4. Reading through other discussion points, other people have similar problems. I thought and still do, that the easiest option was to delete and open up another. That worked fine except I remembered that I had some storage attached to that icloud address. I live in New Zealand.

Because it was valuable software it was never downloadable; also it was a special "OEM" version that could I think only be installed from that CD.
Acrobat 7 doesn't work properly on Windows 7 and later anyway.

You can also re-download most previous purchases (not just songs) from the iTunes Store from the Purchased screen. So, you should be able to get the "one missing purchase" back too. Sign in to iTunes using the Apple ID used to make the purchases. Go to the iTunes Store. (With the new iTunes 12, select the Music category first, then go to the iTunes Store.) Click on Purchased (along right side under QUICK LINKS). From the Purchased screen, you can find and download previous song purchases, at no cost.
You can also re-download purchases from other iTunes categories, such as Movies and TV Shows.

You need to go to https://appleid.apple.com and log into your Apple ID account. You can work from there.
