Esplora Interrupt programming

Hi all,

I am teaching computer structure and programming and thought to use Esplora as an illustration for hardware interrupt programming. Looking at the schematic I see that interrupt programming is not possible as INT lines are used by the LCD and other devices. The only way to access to the sensors is by polling. Do you know if that is the case or am I missing something? Obviously I could do this with other models but I like the compactness of Esplora.
