I'm sorry, I didn't explain it enough.
It is using resistive touch panel. PSoC4 translate touch cordinates as USB HID to send PC(Windows Touch).
could you please help us to understand more clearly what you want to know?
And, you mentioned "any limitation or issue". Which kind of limitation or issue do you want to foreseen (if anything exists)?
Sorry late reply.
We will use USB of PSoC4L series.
Could it set "digitizer" of touch screen with HID to USB component?
