Overview
This is a VI that can send and receive String and 32-bit float data from an iOS app called 'Touch OSC' using the Open Sound Control protocol over UDP.
Description
Open Sound Control (OSC) is a content format for messaging among computers, sound synthesizers, and other multimedia devices that are optimized for modern networking technology. Bringing the benefits of modern networking technology to the world of electronic musical instruments, OSC's advantages include interoperability, accuracy, flexibility, and enhanced organization and documentation. [Extract from Wikipedia page on OSC]
TouchOSC is a universal iPhone / iPod Touch / iPad application that lets you send and receive Open Sound Control messages over a Wi-Fi network using the UDP protocol.
Requirements
Software:
Steps to Implement or Execute Code
1. Run the VI.
2. Enter convenient IP Address of the iPhone/iPad for sending data.
3. Observe the accelerometer measurements on "XYPad" indicator.
Additional Information or Resources
TouchOSC essentially allows you to quickly create iOS user interfaces using its Java-based TouchOSC Editor (See here for download link)
This is then synced to your device using the 'Sync' button in the layout editor and the 'Add' button in the TouchOSC app (seen below) at which point your layout will appear as an option in the TouchOSC layout selector:
I have set up my settings like this, change appropriate settings to suit you like 'Host' which should be set to your computers Hostname or IP Address that the VI is running on. Make a note of the 'Local IP address' which will be used in the VI.
Now if I navigate back to the main menu and click 'Done' I get my user interface:
If my LabVIEW VI is running, I can now receive data from the TouchOSC Interface:
And if I know the correct control addresses, I can send data back and set the value of numeric controls or labels.
Note:
A quick summary of the OSC datatypes supported by this vi:
Received Data type support: f, ff, fff
Transmit Data type support: s, f

Thanks for this! Saves me some time
On OSC server(LV8) download there's the: "no timeout error.vi" missing can you fix that for us?
i really need this so if u can help me with that, it will be great! thanks btw
Hey there, I've added it as an attachment. Enjoy.
thanks alot!
hey, im having trouble connecting my itouch with my pc, im wondering if the touchOSC version has to do with it, because i have the touchOSC 1.2(2008-2009) and does not conects to the IP-address of my wifi conection, and in the layout tab does not have the "add" option.
i already solved that! and yes it was the OSC version!
a video will be great...
People may find this code snippet useful for working out how to get the name of the control from the osc URL:
There is also LabVIEW monitoring / control app avail through iTunes: http://itunes.com/apps/VIremote
It looks interesting, but I haven't tried it.
Thank you for this amazing introduction, everytining works fine with your VI, but i have problems with my own. At first I am new in Labview (I am better in PLC xD) and my questions is:
How can i switch a LED in Labview on, when i press a button in TouchOsc and how can I switch a LED in ToucOSC on, when i am pressing a switch in Labview??
If I know this little things, maybe I am able to programming my own simple VI. An Example (picture) would be great.
Sorry for my bad english, i hope you could understand me^^
Greetings Mr. Maggi and a second thank you!
Hi.
I've seen that the TouchOSC platform is also under development for Android whici is VERY nice and opens a lot of possibilities.
Is the TouchOSC layout you used a default or an example? If not, where can I download it from?
Thanks.
The links to the code are all broken; they all point to https://decibel.ni.com/content/docs/DOC-12289
Guys, it works!!!
With TouchOSC it's quite easy to create new layouts (very close to LV philosophy).
Created a few, downloaded them to the iPod and it worked flawlessly.
And it's fun!!!!!
Hi macaba,
Just tried TouchOSC and it was relatively easy to get going. It's rather amazing to make a change on a PC and see it move a slider on my iPhone.
Getting it to work from PC to iPhone was easy.
However, I have not been able to get the iPhone to PC messages out. I've checked the port numbers and they are OK on both sides (8000). Tried swapping the port numbers around in case Port 8000 is blocked, but still no luck. There is just no message being detected on the PC/LabVIEW end. Any hints?
Regards,
Vito
Very nice. Easy to set up!
Where do those nice gray VI controls come from? Is there a complete set?

Hey Guys,
In addition to this example for OSC, I wanted to make everyone aware of our current OSC package development.
Eventually, you will be able to download these vi's in the package manager.
You can track our progress and contribute to project on our OSC Community Page.
We're currently working on a couple of example using TouchOSC as well as other iPad apps.
We appreciate anything you may have to add to the project. Feel free to get involved by joining the group, posting on project discussions, and uploading projects of your own.

After some struggle with interfacing it works also for me. Perfectly!
This was my main problem: I was running my IPhone and my IPad at the same time, sharing the same addresses ...
My IPhone is off now during my LabView exercises with TouchOSC...
Peter,
I'm glad you were able to get things working.
Have you tried using the OSC vi's in the OSC Community Page?
We'd love to hear about your experience with using them.
