[Qt-interest] help with tslib

[Fabio Martins - Gmail]

*Thank you* for your quick *reply *Chris Burke

So,

I separated the installation of TSLib in the / opt. As I am compiling for
another platform (even x86) but with another processor, I compile on my
machine and put onto the  embedded PC.

The filesys I made for my embedded application.

I do not know when I press the "touch" what data do I get?

Are they the coordinates that I'm getting are more data than the TSLib is
waiting? then so it does not recognize the data?

Thank you...
