Atmel releases version 3.0 of its QTouch library for touch-interface application

Atmel has released version 3.0 of the royalty-free Atmel QTouch software library with up to 64 channels of touch support for all Atmel AVR and select 32-bit AVR32 UC3 microcontrollers (MCUs). This new version features increased channel support, and wider range of supported microcontrollers.


"Our customers continue to require software support for all AVR microcontrollers, especially for touch buttons, sliders and wheels solutions," said Arild Rodland, AVR Product Marketing Manager, Atmel Corporation. "The release of the new QTouch Library allows us to offer our customers superior touch technology for the full range of AVR and selected AVR32 UC3 devices. Furthermore, our customers can now select our tinyAVR, megaAVR, XMEGA, AVR32 UC3A or UC3B device and add touch functionality easily to their design."

The QTouch library stores pre-compiled object code binaries which can be configured individually as touch keys or combined in groups to form sliders or navigation functionality. The QTouch Library also allows full user customization and optimization of the touch function. The precompiled software libraries come with a defined application programming interface (API).

QTouch library can be downloaded from Atmel's touch software product page at www.atmel.com/qtouchlib
