This sample demonstrates how to interface with a touch panel. When touches are
detected a log message is output on the console.

Building and Running
********************

The sample can be built and executed on boards with a touch panel for example
stm32f746g_disco or mimxrt1060_evk. The boards dts file should contain an alias
to kscan0

   as you touch the screen.
