Labview-data saving and sound alert

Hai,
My project is a temperature measurement system. I got few questions here....NEED HELP!!!
1.) How can I save the data in text file?
2.) How can I put "sound" for alert when the mean of temperature is exceed the setting point?
Between, the reading string is A029.0B030.0.......
Thank you!

AVAudioRecorder data usage and sound quality

Witch is the best setting to the right mix of file size(data usage) and sound quality(ability to hear the conversation) when we work with AVAudioRecorder.
Thanks

Alternatively, I can avoid the overage fees by agreeing to change my plan -- increase my monthly allowance -- but I have to pay the difference for all of the months that have already gone by all the way back to the beginning of my contract. In other words, I have to pay for additional GBs for months that are in the past and for which I have no possible way to actually use that data allowance. This is NOT TRUE. You can have the change backdated to the BEGINNING of your CURRENT billing cycle but it WILL NOT go further back than that.
I must say, that as a business model for raking in un-earned revenue, it's pretty impressive. As a customer, though, I'm not terribly impressed.
Does anyone else feel that these practices are just a wee bit unfair, to put it mildly?
I would think that the following would be fair business practices:
(1) If I don't use some GB data allowance, for which I've already paid, then that allowance should roll into the next month OR; Verizon doesn't have roll over minutes and they most likely will not have roll over data.
(2) I should get a refund for data allowance that I don't use. Should you ALSO get a refund for unused minutes while you are at it? I don't watch all of the channels for which my cable company charges me. I would prefer a refund for THOSE before I get a refund for minutes/data from Verizon. I would make a considerably larger refund with that.
(3) Alternatively, since Verizon believes it is OK to charge extremely inflated overage fees, then I feel it's only fair that they refund to me, at that inflated rate, for GBs that I don't use in any given month.
How do the rest of you feel? I feel you should most likely look for a provider which better fits your view on how they should price their service. Good luck.
Sincerely frustrated,
Anton

Only message "data saved" and customices messages

Hello All
Is there a possibility in WAD for planning templates to suppress all messages except "Data Saved" and our customized messages from our planning functions? I know there is the "Internal Display" where one can deactivate warnings and information, but this would also include "data saved".
Is there also a way to not show the messages inside the frame on the top but in an extra popup-window?
Thanks in advance

Hi Clemens,
a good starting point would be to take a look at CL_RSPLFR_WEB_START_SEQUENCE Method EXECUTE. There you see the execution of the planning sequence. This is followed by reading the message log. Hope this helps.

Interleaved data saving and the TDMS Viewer VI.

Hello,
I'm using LabVIEW 2009 Service Pack 1 ( ver 9.0.1 32-bit ).
I was trying to take a piece of data and save it in interleaved mode.
The save operation seems to be completed correctly, but when the TDMS Viewer VI is launched it crashes, and I'm unable to browse the data.
I'm attaching the example I used.
What I want to know is:
1) am I using the write properly? What I'm trying to acomplish is to push down an array if I16 to a TDMS write block, recieve 30 channels of data this way.
2) I managed to use this VI and it crashes, on two PC's, one is a win7 32bit, the second one was an XP. But let me know if this runs properly for you.

I have a buffer that can accumulate up to 65536 I16 values.
In that buffer I get for example 6x 10000 values.
Every "chunk" of the 10000 values is my interleaved data. One point is one channel.
My data is shaped like in the opening post:
http://forums.ni.com/t5/LabVIEW/TDMS-Streaming-in-interleaved-mode/m-p/1189201#M513943
Since I'm running a windows machine, sometimes I'll get 5x 10000 values, sometimes it will be 3x , sometimes 6x during one buffer swipe.
The data rate and the channel length is variable.
But let's talk about one case:
10k channels and 10 kHz rate of I16 vals.
That gives me roughly 200 MB/s of data that I need to get out of the buffer.
What I want to do on my PC is take that data, and save it interleaved to a TDMS file, while being able to safely stay above the 200 MB/s.
I would be intersted in aiming for 300 MB/s so that if we push our card further down the line, I'm not stuck with the streaming bandwitch.
I have noticed that unfortunately if you use an ammount of channles that is 10000 the writing performance drops dramatically.
What I figured out is that I'm not conducting 1 write on 10000 channels on a small ammount of data. But rather than that a large accumulated amount of data (like 8000 x 10000 of I16)
And I split the save of 10000 channels into 10x 1000 channels save.
First channs from 0-999 , than 1000-1999 etc.
All is done in interleaved mode.
This is Very Very fast indeed. I got rates of 360 MB/s. That's smoking fast!
Now the trick is... to handle the appropriate data shaping in the RAM, from my buffer, to the large shaped RAM chunk, that will be cut in to pieces for Streaming. LV is designed for data flow and copies data a lot, hence I get easlity in the out of memory problem, I'm going to have to use some ticks like storing the data structure via a VI Server call, or perhaps queues don't know yet. But I'm going to do some reading on that and it seems that this should be achieavable.
Thank you both for your input,
I will post if I get stuck.

Since upgrading to 3.6.15 some settings are not saved, and the alerts when changing between encrypted content are totally out of synch to the actually occurence

The settings dialog box cuts off the bottom ofthe box content as it seems to be having problems with font rendering.
Settings such as "Show download window" and "Ask me where to save" apparently revert to defaults rather than saving the settings.
The encrypted content alerts are out of synch. They claim to be going from encrypted to non-encrypted when neither page is encrypted. Or warn of non-encrypted content on an encrypted page when the whole page is unencrypted.
3.6.14 had none of these problems.

Update to 3.6.16 has fixed this problem.

Labview data collection and storage?

for a complete labview beginner, what is the best way to collect data from hardware connected by rs-422 serial port?
Solved!
Go to Solution.

At the moment i've set up the attached but I can only get it to input one set of values. how can I get it to continuosly output the files? Secondly I would rather out put them to a spreadsheet format, with the five different numbers (three from I/O assistant and two from Date/Time String) in diferent columns? Im trying to use the write spreadsheet VI but it needs an orange connection?

How can I get Data from the Sound cart in Labview? Does a VI exist?

How can I get Data from the Sound cart in Labview? Does a VI exist?

Yes, there are VIs for acquiring data from Sound cards. And examples too. If you don't have LabVIEW yet, do a search on NI's site for example VIs.

DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file

Hi
DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file
Two main
sections:
1)
Perform
write and read operations to and fro different spread sheet files, such that
each file have a single row of 32bits different binary data (analogous to 1D
array) where the left most bit is the MSB. I don’t want to manually enter the
32 bits binary data, I want the data written or read just by opening a file
name saves with the intended data.
      2)
And
by using test patterns implemented using the digital pattern generator or build digital data functions or otherwise, I need to
ensure that the
            binary data written to a spreadsheet file or any supported file type
then through the NI-USB 6509 is same as the data read.
I’m aware I can’t use the simulated
device to read data written to any port but if the write part of the vi works I
‘m sure the read part will work on the physical device which I’ll buy later.
My Plan
of action
I’ve
created a basic write/read file task and a write/read DAQ task for NI USB 6509
and both combine in a while loop to form a progress VI which I’m confuse of how
to proceed with the implementation.
My
greatest problem is to link both together with the correct functions or operators
such that there are no syntax/execution errors and thus achieve my intended
result.
This
project is one of my many assignments for my master thesis, so please i’ll
appreciate every help as I’m not really efficient with LabVIEW programming but
I prefer it because is fun and interesting if I get to know it.
Currently I’m
practicing with LabVIEW 8.6/NI DAQmx 8.8 Demo versions and NI USB 6509
simulated device.
Please see
the attached file for my novice progress, thanks in
advance for the support
Rgds

What does your file look like? The DAQmx write is expecting a single U32 value, not an array of I64.

Reading data saved on previous version of Labview

I've recently bit the bullet and upgraded to Labview 8.0 after using Labview 7.0 for a good few years now. I'm currently experiencing problems accessing data saved on the previous version of Labview which I've been working on until the upgrade.
An example is the waveform files saved on Labview 7.0 which I'm trying to read using Labview 8.0. A dialog box appears when I try to use Labview 8.0 to read the waveforms advising me to convert the files to the new version of Labview which I've duly agreed to. However, it appears that the conversion process has managed to corrupt the waveform files as I am unable to access it on either Labview 8.0 or 7.0.
I'm including a couple of files to highlight my point, one saved on Labview 7.0 and the other converted to Labview 8.0 by the programme.
Cheers.

I have no sound alerts on my iphone5. My software is up to date. I can hear on a call but I have no text alerts, no ringtones, nothing that involves sound! Everything was okay a few hours ago. I have no idea how this happened. Please help!!

I tried the compressed air, Qtip, etc... still nothing. Called Apple again.... and we did a complete factory reset from iTunes, wiping everything out... still no sound, which proves that it is a hardward problem, under warranty, I have to have phone replaced No Apple repair centers within 300 miles of me! So... shipping phone off today. Bummer.

I have 2 apple id's with different apps and data saved under each. It's very annoying so now I want to create a new id with my primary email address I use now. If I do that is there any way to transfer all my saved apps and app data like game saves etc?

I have 2 apple id's with different apps and data saved under each. It's very annoying so now I want to create a new id with my primary email address I use now. If I do that is there any way to transfer all my saved apps and app data like game saves etc so I don't lose all of that information and can easily switch to a singular apple id?

Apple does not transfer content bought with one Apple ID to another Apple ID. Apple will not merge two Apple IDs.
If most of your content was bought with the Yahoo! Apple ID but you now want the Gmail address for your Apple ID, the trick will be to change the address used for the Yahoo ID with the Gmail address. However, to do that you must first free the Gmail address from that other Apple ID. Use the instructions from Apple to substitute another address that is not used as an Apple ID for your Gmail address in the Apple ID with the Gmail address. Then, when the Gmail address is no longer used in an Apple ID, you can use the same instructions to substitute the Gmail address for the Yahoo address in the Apple ID with the Yahoo address.
Changing the email address you use for your Apple ID -

How do i save a calender i have created with the photo and the dates saved on separate pages?

how do i save a calender i have created in photoshop with the photo and the dates saved as two separate pages? when i save as pdf or jpeg they are authomatically saving 1 pg with the photo and dates on one page. This is causing problems when i print.

Hi there, in case your printer cannot print very large, you can also crop down two versions and print them as separate documents.
1) Create a guide where you would like to split the pages by clicking on the ruler (hit command R if they are not showing) and dragging to the desired area.
Creating the guide will make it so you can be precise in the way you split up your page, and so that no part of the image will be repeated or lost.
2) Select the Crop Tool and fit the crop area to the top half of your calendar, using the guide you've just made to snap to the right spot. Hit return to finalize the crop.
3) Go to File > Save As. Name the file something like calendar_top and select the desired file format. Hit "Save."
4) Once you get back to your calendar file, Go to the History panel and select "Drag Guide." This will take you back to the step before you cropped the image.
5) Repeat the steps as before for the bottom half of the calendar, once again using the guide to help you make your crop area.
So then you would just print each of the two pages individually. The images will not be contained within one document, but if you have Acrobat you could combine the files.
I hope this helps!
