Atmel introduces QTouch Library software

Atmel Corporation has released the QTouch Library: a royalty-free software library providing access to the QTouch technology.

Without the need for external devices, the QTouch Library adds capacitive touch of pre-compiled and object code binaries, which can be configured individually as touch keys or combined in groups to form sliders, navigation wheels or combinations of all these.

The QTouch Library allows full user customisation and optimisation of the touch function.

Atmel's complete development tools system, available now, facilitates the development of a reliable high-performance touch application based on the AVR and AVR32 microcontrollers.

With the AVR and AVR32 microcontrollers, adding touch functionality to the application is done while still allowing the majority of the microcontroller resources to be used for the application software.

Ingar Fredriksen, Atmel's AVR product marketing director, said: 'Adding touch capability to the user's application is a unique feature with the QTouch Library, which Atmel offers due to the high performance of our microcontrollers.

'Other industry alternatives use all the microcontroller performance for the touch function, not allowing for any application software to run reliably simultaneously.

'This extension of the QTouch Library allows Atmel to offer its superior touch technology for a full range of AVR and a selection of AVR32 UC3 devices.

'Atmel's customers can freely select one of our TinyAVR, MegaAVR, XMega or AVR32 UC3A devices and add touch functionality to their design.
