Atmel Corporation recently announced version 3.0 of the royalty-free Atmel QTouch software library with up to 64 channels of touch support for all Atmel AVR microcontrollers (MCUs) and select 32-bit AVR32 UC3. The QTouch library also supports Atmel’s patented charge transfer signal acquisition technology for robust sensing on the AVR and AVR32 MCUs. This technology allows QTouch to outperform other capacitive touch sensitive acquisition methods in electrostatic discharge (ESD) and electromagnetic compatibility (EMC), overlay thickness and signal-to-noise ratio. The QTouch library, combined with Atmel’s AVR development tools, can now provide a fast, easy path to a reliable, high-quality touch interface for our designers.For more product information, visit the Atmel Web site.
