HY32D and XPT2046

Frank I have and LCD module HY32D but the problem is that it does not have any x y pins. So how should I use xpt2046 to detect where the screen is touched. Any help would be greatly appreciated.

It will give you some solid idea. He used the same BusOut command to access pins simultaneously

Note: Original author has deleted its code but you can still see the code by checking its old revisions
