Touch sensing application specific Touch-Library for Atmel's AVR microcontroller

Atmel's newly released advanced Touch-Library resides on the microcontroller instead of a separate chip resulting in a highly cost effective solution, which will be provided 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.

Atmel offers a complete development environment that now 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 the industry's most robust touch solution, particularly in demanding applications. This has multiple advantages for the designer, for example a high signal to noise ratio that improves the systems design margin, increases EMC performance and provides high ESD tolerance. 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 multitouch screen 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. "Requests for AVR microcontrollers with integrated touch are an increasingly important part of the UI related microcontroller business. The Touch-library targets this market, and further strengthens Atmel's position as the technology leader in touch sensor solutions," he continued.


The Touch-library is available now 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.
