Software

Studio 7 is the integrated development platform (IDP) for developing and debugging all AVR® and SAM microcontroller applications. The Microchip Studio 7 IDP gives you a seamless and easy-to-use environment to write, build and debug your applications written in C/C++ or assembly code. It also connects seamlessly to the debuggers, programmers and development kits that support AVR and SAM devices.

Additionally, Studio includes Microchip Gallery, an online app store that allows you to extend your development environment with plug-ins developed by Microchip as well as third-party tool and embedded software vendors. Studio 7 can also seamlessly import your Arduino sketches as C++ projects, providing a simple transition path from Makerspace to Marketplace.

QTouch Library for PTC - The QTouch® Library is a royalty-free software library for developing touch applications on AVR and SMART ARM-based microcontrollers with Peripheral Touch Controller (PTC).

Developers can use it to easily integrate touch-sensing capability into their applications. The library can be used to develop single-chip solutions for many control applications or to reduce chip count in more complex applications.

The library supports both self-capacitance and mutual-capacitance acquisition methods.
