Constantly updating indicators

I have 8 input booleans in 4 sequences, 0-3. I want to monitor these inputs with 8 LED booleans outside of the sequence and have them constantly updating. Right now I have to have 8 LED booleans for each of the sequences. Is it possible to do this?

It's not a problem as you can create local variables for one of your led clusters... Look in the attached file how it can be done for your vi.

Best way to update indicators in state machine ?

What is the best method to update indicators constantly in a SM ? ...
MY INDICATORS: I want to update the cluster of OUTPUT INDICATORS for ever new update that is happening inside the FOR LOOP (see next image). How could I achieve that ?

Since on my machine, the second screenshot is cropped, i cannot see the complete FOR loop. You do refer to the loop writing to VISA, correct?
If so:
- Is this loop timed? If so, what is the average iteration time? Note: if this is faster than about 50ms, you should not update the indicator in every iteration as the human simply cannot see changes that fast. An average user would only see some flickering and from time to time something "readable".
- Do you update the indicators elsewhere as well?
Possible solution:
- As Yamaeda suggests: Put the indicator in the FOR loop. Works well if only this loop updates these indicators.
- Local variable: As dataflow serializes access to the indicator (variable in loop, terminal outside the state case), you wont have race conditions. On the other hand bears risks if someone introduces concurrent loops using the same indicators (variables).
- Property node "value": Same as local variable, but is bound to UI thread. Therefore, it takes more time which induces performance drawbacks. On the other hand, a property node has error in/out and is better suited to be placed in well designed dataflow programming.
- Extract UI updates from the state machine and introduce a parallel running "UI Update" loop. Refer to the Producer/Consumer template for an initial start point.
hope this helps,

Family sharing if you don't want to constantly update your devices and make your apple products redundant

Hi everyone,
My kids have taken over our older Apple devices - i.e. iPhone and iPad - and have currently got our old stuff, apps, emails etc on their devices. I want to start these devices on a fresh start - although they've got a selected few apps that they say would be a disaster to start up again if we deleted everything.
If I go for family sharing, I believe everything has to be IOS 8 or better (probably IOS 9 tomorrow and IOS 10 the day after tomorrow - argh...). But if I upgrade the older devices (if they can upgrade at all!), they will be awfully slow or not work at all...
Apple shop recently suggested me an alternative: to buy vouchers for my kids and set-up a new apple-ID for them on each device as an alternative, although I don't have control over their purchases, but once the voucher has been used, there won't be any more purchases - only free stuff downloaded. So I don't need the kind of control that family sharing has.
All I want them to have is face-time and an own apple-ID on their devices - and let i.e. my sons FIFA15 app continue as he's been building his team for months on "my" old iPad before he took it over himself.
However, now I cannot set up a new apple-ID because there's no more me.com and I can't create an apple ID for them as they are too young...argh (again!) - (did I mention that argh is my favourite apple-expression the latest few years? Bring back the old times please....!).
What to do?
Yes, I know - go to the apple shop and give them more of my cash to get brand new devices that needs updating and replacement in a year and throw away the old devices and pollute the world further. I would get family sharing going yes, but I would also be a lot poorer and feel like a fool for buying more apple gear.
Any other alternative - using what we've already got?
Stop apple from constantly updating and requiring upgrades of products and inventing new stuff....? It drives me nuts - but probably I wouldn't get away with that suggestion either...
Sorry for my alt-modisch view on all this or if any of my sarcastic apple comments are putting any of you off. Appreciate any feedback or ideas from you guys.

No replies to this one?
Come on guys - whoever still likes apple products - come to their defence and show that Apple isn't totally rubbish after all????
Sarcasm aside, much appreciated if you have any tips for me...

Constantly updating in CS4

Photoshop and all the other CS4 programs in my production premium package are constantly updating. Every time I go to check for update, it says that the same stupid updates are available even though I already installed them. I don't know if they even installed or there is some kind of glitch that is making this happen. I have pasted the DLL files from the 4.0 version cue into the 4.0.1 file, and it fixed a previous problem, but now I'm not sure if the solution to those problems made new ones. Is anyone else experiencing these problems?

Have you ever tried manually downloaded and installed the updates?

What are the alternatives to updating indicators using property nodes?

Hello,
I'm building a VI which needs to update several controls/indicators at multiple points throughout its execution. It also needs to be able to accept new values from the controls at any given time.
The problem with this is that all of these controls and indicators are on the front panel of another VI which is calling my VI. The current version of my program updates all of these controls and indicators using references and property nodes (each indicator/control that needs to be used has its own reference control on my VI, and these references are then sent into property nodes), which naturally makes it slow.
At the moment I'm considering rebuilding my VI in such a way that the main one is able to retrieve the data without using references, but this will be not only very time-consuming but also difficult and possibly even impossible without my code turning into a massive disorganized pile (especially since the lab computer is slow enough, and the main VI large enough, that pressing the 'clean/reorganize block diagram' button causes a crash).
Any alternatives to this? Queues?
Solved!

Itunes 4.9 hangs and constantly "updates" ipod shuffle

Hi,
I was happily using iTunes 4.7 up until a new hard disk about a month or 2 ago. I didn't like OS X.3.9 and there were major low volume issues for me with the iTunes 6.? that Apple had installed.
I downgraded everything to X.3.8 and itunes 4.7, and things were OK. My Podcatcher (Podsafe 0.4) however has had issues lately with downloading podcasts and is no longer under development. So I found the iTunes 4.9 update and installed it (repaired permissions before and after).
2 problems now.
1. When my Shuffle is plugged in iTunes constantly (I mean non-stop) displays "updating iPod do not disconnect" for about 5 seconds then "ipod update is complete" for about 2 seconds then back to "updating ipod" etc etc.
2. If I try to change any info (e.g. stop or start time, or genre) iTunes hangs and no matter what I click it won't respond for about 3 or 4 seconds.
I've run the usual maintenance. Any ideas what's going on? Is iTunes 4.9 buggy? If yes, how do I go back to 4.7? I liked 4.7 just fine - my only purpose in updating to 4.9 was for podcatching. I can upgrade my NetNewswire to enable podcatching.
Thanks.

It's not against the track but against the playlist that's on the iPod when viewed in iTunes. It appears to the far right of the playlist underneath the iPod in the left-hand pane of iTunes. The same spot where the eject button would appear if it was something that could be ejected.
I never noticed that iTunes would show the playlists for an iPod before. I had never thought of looking at them, and now that I have it shows this exclamation mark beside some of them. I have compared the these playlists on the iPod to the playlists on my computer and they contain the same number of tracks.

Is there any way to constantly update files from pc to ipad (Over WiFi)?

I use my iPad as a reader. i.e. I work on documents on my PC, then transfer them to my iPad and use those documents for quick reference on the go. Now, the problem is that I have to keep updating/modify the documents on PC. So every time I have to delete the older documents from my iPad and copy the newer ones. Now that's so time consuming.
A one way (PC to iPad) sync is what I need. I know that this can be done with by lot of apps (dropbox, sugarsync, etc.), however they need internet connectivity. I want to transfer/sync over my home network. On android there are lot of apps to do this while I am yet to find a decent one for the iPad. Can anyone please suggest me one or a workaround?

Look at goodreader or DocsToGo. It will sync files from any file servers. Set up a file server on your machine. ie. share a folder from your machine. Read below for more details.
Don't you have the internet at home? So what's the problem with dropbox etc?
How are you copying now?

ITunes constantly updates same songs unnesessarily

For some reason, iTunes is acting strange.
I recently moved up to a new 60GB 5G iPod from an old-school 10GB 2G model I've been using for years.
Anyways, after uploading my whole 30GB audio library and a few video podcasts to the new iPod, I've noticed something strange and annoying.
Every time my iPod triggers an update cycle, it ALWAYS updates the same ~350 songs and one video podcast. And these aren't getting updated because of something like a rating change or a play count increase or something similar. I just can't figure this out.
It's kind of a pain, since I might just want to add one new album or something small to my iPod, but instead, along with that album, it has to spend another 20+ minutes updating these same songs that don't even NEED updating.
I'm not willing to do a restore just yet, as with the amount of stuff that's on there.
Also, I NEVER had this problem with these albums and my 2G iPod, so I don't know what to make of it.
Any help would be appreciated.

Constantly updating

I have Organizer set to watch folders. The problem is, every time that I open organizer it goes through a painfully slow "updating", checking watched folders, mayber 3 minutes worth and every time it finds photos to add...however, I haven't moved, added or renamed any files. WHY?

Good luck.
Always make sure all applications not in use are closed.
Press your menu key for about two seconds to see what apps are open and to close them, use your menu key > close or exit. You cannot fully close the Homescreen, phone, and BBM icons... make certain the browser is closed with Menu > close, although it will still appear in the app ribbon.

Constantly Updating Photo Library

On both my "new" iPad and my iPhone, it's driving me to drink. About every 5-10 minutes, when I'm working in iPhoto on either device, all of a sudden, it starts doing its "Updating Photo Library" thing and that stops me from working. It is very, very annoying. I looked at tech articles and the last few days here in this subject area and haven't spotted any information.
Does anyone have any clue as to what causes this? And, if so, if there is anything that I can do bring it down to a bearable frequency? TIA.
(P.S. Looked at a couple suggestions that showed up on the right after I posted. Those users had problems syncing. I didn't originally nor have I had any problems syncing.)

This is a common occurrence and there is no way I know of to stope the updating of the library. Any changes to the photo library will result in updating in iphoto for iOS. You can leave feedback on this to Apple here:

Problem updating indicators

Hi,
I have a numerical indicator whose value is calculated using another control. I set up an event so that when a change of value occurs on the control, the indicator's value is recomputed. This works fine.
However, I then added a second event to the case, for a second control which also affects the indicator's value. When a change of state occurs in this second control, the indicator's value does not change! This is even though a breakpoint is hit when the change of state occurs.
Does anybody know if there is a complication with the ui/updating etc which I'm not aware of yet? I'm a beginner to LabView.
Thanks,
Martin

Why not handle both events in the same "case". This way you can take BOTH values which affect the indicator, do a single calculation to generate the new indicator value and then update it.
Hope this helps
Shane.
PS You can add multiple events to a single handler case by right-clicking on the case header and choosing "Edit events handled by this case". There you can add (large + in the upper window) extra events to the list of events which will fire that single case.Message Edited by shoneill on 05-24-2005 12:58 PM
