TouchScreen as a single function

[lappa]

Is it possible to write the TouchScreen routine into a single function, with a menu, so it is not ‘visible’ to the rest of the functions/sketch?
On the XPT2046_touchscreen you can use ‘break’ after the menu call due to the presence of a while(true) statement but I can’t see something similar within the TouchScreen routine.

of course it's possible.
but you need to post your code to understand why you mention "menu".

I stuck at it and solved the problem late tonight,
