my labview is now fast...and this is using event structure. and u know my arduino program was continously writing serial n thus was busy doing that. now since i removed that code n stuffs are working much better...

now last my problem is that i want the i want to make an event occur iinside the event using led outside the event structure..i have attached my prog. i want to click tone select led only for two seconds n want to transmit that particular code for two seconds and remaining codes continously....

means i want to control an event from led outside the event structure

I spend some time trying to clear your code. There are still a lot to do, but I don't have more time to day.

There are two problem as I can see it:

The inner While loop is not good.

In one of the inner Case structures with option 99 I think there is an wire wired wrong. 

Your need to think a lot about all those feedback nodes. Think about where your are taking the data from, the current data (before the node) or the old data (after node).

And all the inner case structures and feedback nodes can, and should be change with sub-vi and arrays with a replace array element. I can hopefully show you that tomorrow.

Take a look.
