Tools! Atmel Studio 6.2 IDP Atmel Software Framework QTouch Composer http://www.atmel.com/Microsite/atmel_studio6/ Atmel Software Framework http://www.atmel.com/Images/WP_Studio6_July2012_FINAL.pdf QTouch Composer http://www.atmel.com/Microsite/atmel_studio6/qtouch_tools.aspx 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. Atmel Studio 6 is free of charge and is integrated with the Atmel Software Framework (ASF)—a large library of free source code with 1,600 ARM and AVR project examples. ASF strengthens the IDP by providing, in the same environment, access to ready-to-use code that minimizes much of the low-level design required for projects. Use the IDP for our wide variety of AVR and ARM Cortex-M processor-based MCUs, including our broadened portfolio of Atmel SAM3 ARM Cortex-M3 and M4 Flash devices. Atmel Studio 6.2 is now available, adding advanced debugging features such as Data and Interrupt Trace, improved RTOS integration, and better ability to debug code that has been optimized. With the introduction of Atmel Gallery and Atmel Spaces, Atmel Studio 6 further simplifies embedded MCU designs to reduce development time and cost. Atmel Gallery is an online apps store for development tools and embedded software. Atmel Spaces is a cloud-based collaborative development workspace allowing you to host software and hardware projects targeting Atmel MCUs. In summary, standard integrated development environments (IDEs) are suited for creating new software for an MCU project. By contrast, the Atmel Studio 6 IDP also: Facilitates reuse of existing software and, by doing so, enables design differentiation. Supports the product development process with easy access to integrated tools and software extensions through Atmel Gallery. Reduces time to market by providing advanced features, an extensible software eco-system, and powerful debug integration. The New Project Wizard in Atmel Studio 6 provides a step-by-step guide through the whole touch project setup, and automatically generates a touch project complete with initialization code and power management. QTouch Composer includes real-time data graphing and tracing. During debugging, this capability records all data from the target, storing it for later playback. This allows zooming and inspection on a recorded data set. The Validation Wizard provides an easy and intuitive way to test system performance. Your touch project can be automatically updated with recommended changes performed by this wizard. QTouch Composer also includes a power analyzer, which allows real-time monitoring of your microcontroller's power consumption. With the power analyzer, you can easily profile and visualize the amount of CPU time spent on the touch sensing code. This will support you in developing the lowest power touch
