Atmel Corp. has announced the availability of its Touch-library that is integrated in the microcontroller instead of a separate chip resulting in a highly cost effective solution at no additional cost. The library consists of precompiled and verified binary files that can be configured individually as discrete keys or can be combined at will, as groups, to form wheels and sliders.

The company offers a complete development environment that makes it easy for a user to develop a touch system based on their AVR microcontroller. The AVR core combined with Atmel's QTouch technology provides a robust touch solution, particularly in demanding applications. This has multiple advantages for the designer, including high SNR that improves the systems design margin, high ESD tolerance and increased EMC performance. In addition, designers can address applications where reliability is required, such as stove tops, wall ovens, automotive applications and where high moisture levels are present.

"Atmel has supplied fixed function and custom capacitive multi-touchscreen solutions to mobile handsets and other high profile, high volume applications. Through the extension of this technology to a user-driven Touch-library we are making superior touch technology available for all customers and applications," said Ingar Fredriksen, Atmel's AVR product marketing director.

The Touch-library is available for download at the product web page together with AVR QTouch Studio, royalty free front end software supporting the two available demonstration boards TS2080A and TS2080B, supporting ATmega88, ATtiny88, ATmega88PA, ATmega168P and ATmega328P, respectively.
