This repository contains the source code and configuration files of the Arduino Core for Atmel's SAM3X processor (used on the Arduino Due board).

This core is available as a package in the Arduino IDE cores manager. Just open the "Boards Manager" and install the package called:

• Arduino SAM Boards (32-bit ARM Cortex-M3)

Use Platformio extension with atmelsam framework

[env:due]
platform = atmelsam
framework = arduino
board = due
    

Development SAM4 Version

[env:sam4s4a_SAM4]
platform = atmelsam
framework = arduino
board = motionbow
platform_packages =
    framework-arduino-sam@https://github.com/chepo92/ArduinoCore-sam.git#dev-SAM4SCore
    toolchain-gccarmnoneeabi @ 1.40804.0

There is a dedicated section of the Arduino Forum for general discussion and project assistance:
