The Arduino Due is a small form-factor embedded computer built around the Atmel AT91SAM3X8E microcontroller, which is an ARM Cortex-M3 class processor with associated peripherals. It is quite different from earlier Arduino models that are based on an Atmel AVR microcontroller.
The Arduino IDE is simplified for casual tinkerers; its language is C++, but a custom preprocessor is used to change the code before it is compiled to C++. To do proper C/C++ development, a classic build environment is needed.
The Atmel SAM4E XPlained Pro is a development board built around the Atmel ATSAM4E16E microcontroller, which is an ARM Cortex-M4 class processor with associated peripherals. The processor has a hardware Floating Point Unit (FPU) that supports single-precision IEEE-754 floating point operations.
The goal of this project is to provide a script that builds a cross-compiler, C library, and associated tools to do Linux-based development for the Arduino and XPlained Pro boards.
We try to support the following features:
- A working cross-compiler GCC build environment for ARM-based development.
- A working newlib or other small C library
- Support for the FPU in the Cortex M4 processor.
- The appropriate CMSIS / ASF stuff for the ARM chip
- A working FreeRTOS or other minimalistic OS.
- Flash tool (BOSSA or OpenOCD)
- Working C++, STL
- Minix?
