Overview
The QTouch Library is a royalty-free software library for developing touch applications on SMART ARM-based microcontrollers with Peripheral Touch Controller (PTC).
Developers can use it to integrate touch-sensing capability into their applications by linking the library into firmware. The library can be used to develop single-chip solutions for many control applications or to reduce chip count in more complex applications.
The library supports both QTouch (self-capacitance) and QMatrix (mutual-capacitance) acquisition methods.
QTouch Library: Use this library for devices without PTC.
