my understanding of most resistive touch Screen, is that it is basically a 'X' and a 'Y' voltage divider, that you connect to 2 analog inputs....
How fast is it to convert ?
I want to build an Airsoft target: the pellet would hit the touch screen, and an XY coordinate would be extracted.
My concern is about the "duration" of the hit on the Touch Screen; would it last long enough to be extrated by the uController ? My intention is to have a uController dedicated only to that task, nothing else. result would be pushed over I2C
Wait - get hit - extract XY - Push XY - Wait
I plan on using the "touch screen layer" only, on top of something softer than a piece of glass, in order to:
A: survive the hit without breaking B: being softer, I'm guessing that bouncing would be less than on a piece of glasse, therefore being in contact a little bit longer
Any comments, warning, ideas ????
If it's plain stupid as an idea, let me know !
