Atmel has expanded its royalty-free touch switch library to cover more of its microcontrollers.
"This extension of the QTouch Library allows Atmel to offer our tinyAVR, megaAVR, XMega or AVR32 UC3A devices," said AVR product marketing director Ingar Friedriksen.
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.
"This is an important step in our strategy to offer our QTouch solution to the entire range of Atmel's microcontrollers," said Friedriksen.
QTouch needs no custom hardware, relying on conventional I/O ports and a handful of passives for the touch interface.
The library is available now, as is free front end software supporting the firm's ATAVRTS2080A and ATAVRTS2080B demo boards, for ATmega88 and ATtiny88 respectively.
