Hi all,
I don't know what happened but actually display refreching is about 3 seconds.
I remarked that when I open a VI tha uses tne display VIs, Labview is searching on "update.ctl" and other files. these files are not in "C:\Program Files (x86)\National Instruments\LabVIEW 2009\vi.lib\Embedded\ARM\EK-LM3S8962\display"
I allready tried to reinstalle Labview and ARM module, but the files are not reinstalled.
How to solve this?
thanks

This happen only if you try to use VIs from a previous version (8.6).
When open the VI press "Ignore Item" button, and then just replace all instances of update.ctl with booleans, perhaps only TRUE or FALSE constants:

I have no 8.6 version istalled.

The refresh rate might be affected by your algorithm: number of display VIs, string convertion, etc.
I just can asure you the update (which sends the entire display memory to OLED) takes about 60 – 100 ms in a faire system (the task making the update is allowed to run)

I just modified the AI.vi from the mentioned example so I can estimate the "refresh rate" (see only if next ms is indeed the next one)
These are results for 100ms (left) and 30 ms (right):

So the code can't be the responsible.
You said that it's not the missing ctl too.
What can it be so?
