We'll tell you all you need to know to start evaluating and working with this product.




The Atmel® QTouch® Library is a royalty-free software library (GCC and IAR™) for developing touch applications on standard Atmel 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 Atmel Gallery
  • IAR: Downloads available below

Atmel QTouch Library PTC: Use this library for devices with PTC.
