Software

Atmel Studio 6 - Atmel® Studio 6 is the integrated development platform (IDP) for developing and debugging Atmel ARM® Cortex®-M and Atmel AVR® microcontroller (MCU) based applications. The Atmel Studio 6 IDP gives you a seamless and easy-to-use environment to write, build and debug your applications written in C/C++ or assembly code.

QTouch Composer - The Atmel QTouch® Composer, formerly called QTouch Studio, is fully integrated in Atmel Studio 6, so you can easily and seamlessly develop capacitive touch functionality for your application. This simplifies the design process by tying together the tools required to edit the code in Atmel Studio 6 and tune the touch design in QTouch Composer.
