Vito,
Maybe I'm missing something. How exactly can one make a physical
connection with the iPad, when it *only* has the apple dock connector?.
It lacks a USB port (this is not an oversight by apple).(it also doesn't
have an SD card slot)
The Raspberry provides the network connection layer that the USB-6009
lacks. TCP/IP stack is not lean so it would not be an easy feat to get
it to run within the DAQ. Now LabJACK seems able to do this for about
$300.00 - Include a Ethernet port AND USB.
I and others I've worked with have looked at an iPad remote interface
for LabVIEW based products. The Web browser is not the solution, it's
quirky and depends on browser plugins. Even with Windows, there are
display and update issues with IE and the LabVIEW web server, that can
be show stoppers.
Other Web Browser short comings (IMO)
1. Why would I want to puke the same screen that's running on a 1920 x
1024 monitor on a 7" screen?.
2. Why would I want to offer access to the 'verbose' version of program
remotely on a touchscreen?.
3. One needs to consider and design both interfaces, appropriate for
the method and requirements of that interface.
I've done countless applications that have a GUI and an API and even
developed a remote GUI that works thru the program API. They rarely are
the same interface.
I think the solution will be a proper 'drag-n-drop' GUI builder native
for XOS. This can then communicate via TCP/IP and UDP.

> I assume John Brohan wanted to be able to program the Raspberry Pi with it in turn being connected to an NI 6009. The product in question does not allow any programming on the Raspberry Pi. Instead the Raspberry Pi just takes the NI 6009's data and formats it suitable for display on an iPad running Data Dashboard, using fixed C code on the Pi. For the announced product, it would have been better to put the software on the iPad and have it directly connect to the NI 6009. The Raspberry Pi adds no value.
