What's the issue here? The touchscreen input is just a trigger

I'm not sure that's going to be tractable, while the ADC usage may be the
same I'd expect to see a bunch of other logic around them for pen down
detection. I'd guess it is going to be more tractable to have a library
that most ADC touchscreens can share which handles the actual data
transfer bit of things but has extra glue logic around it to make the
actual device.
