This shield comes with a resistive (STMPE610 controller)
or capacitive (FT6206 controller) touchscreen. While the
Zephyr RTOS supports display output to these screens,
it currently does not support touchscreen input.
touchscreen input is supported only on Capacitive Touch version.
More information about the shield can be found
at the `Adafruit 2.8" TFT Touch Shield v2 website`_.
