Detailed Description

Abstract base class for touch controllers.

The public interface is non-virtual; concrete drivers (e.g. idfxx::lcd::stmpe610) customize behaviour by overriding the protected do_* hooks, mirroring the standard library's non-virtual-interface pattern (cf. std::pmr::memory_resource).
