QTouch Library for PTC


The QTouch Library is a royalty-free software library for developing touch applications on AVR® and Atmel SMART Arm®-based microcontrollers with Peripheral Touch Controller (PTC).

Developers can use it to easily integrate touch-sensing capability into their applications. 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 self-capacitance and mutual-capacitance acquisition methods.

Note: These libraries do not support AVR or Atmel SMART Arm-based microcontrollers without PTC.

QTouch Configurator


QTouch Configurator is integrated into START, and offers an innovative, intuitive and graphical configuration to help design your touch application. START is an online tool - no installation is required. When you are done with your configuration, download it for use with your preferred integrated development environment (IDE), and continue development.

Data Visualizer

Data Visualizer is a program that processes and visualizes data. For example, it allows designers to plot touch signals in real time to help tune and monitor power consumption.

QTouch Tools for SAM with PTC


QTouch Composer

QTouch Composer is a complete set of tools for developing and tuning capacitive buttons, sliders and wheels designs—and is now fully integrated into Atmel Studio 7. It provides the most advanced, integrated environment for development of touch-enabled AVR or Arm processor-based applications.

 

QTouch Composer is available through the extension gallery in Microchip Studio
