ATMEL QTOUCH LIBRARY
Overview
The QTouch Library is a royalty-free software library (GCC and IAR) for developing touch applications on standard AT91SAM and AVR microcontrollers.
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.
The libraries are available for two compilers:
- GCC: Distributed through the Gallery
- IAR: Downloads available below
QTouch Library PTC: Use this library for devices with PTC.
