2 Introduction
ATMEL QTouch Library is a royalty free software library (available for GCC and IAR compiler tool
chains) for developing touch applications on standard AVR and SAM microcontrollers. Customers
can link the library into their applications in order to provide touch sensing capability in their
projects. The Library can be used to develop single chip solutions for control applications which
have touch sensing capabilities, or to develop standalone touch sensing solutions which interface
with other host or control devices.
Features of ATMEL QTouch Library include
This user guide describes the content, design and use of the QTouch Libraries. This should be
read in conjunction with all of the applicable documents listed below
The intended readers of this document are engineers, who use the QTouch Library on ATMEL
microcontrollers to realize capacitive touch sensing solutions.
