Software Tools


Microchip Studio Integrated Development Environment (IDE)

Microchip Studio is the integrated development platform (IDP) for developing and debugging all AVR® and SAM MCU applications. Microchip Studio 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 SAM devices.

Advanced Software Framework (ASF3)

ASF3 is an MCU software library providing a large collection of embedded software SAM MCUs. It is integrated in Microchip Studio IDE with a graphical user interface or available as stand-alone for GCC and IAR compilers.

Arm® GCC (Arm-GCC)

The Arm GNU Toolchain is a collection of tools/libraries used to create applications for Arm processor-based MCUs. This collection includes compilers, assemblers, linkers and standard C, C++ and math libraries.
