1. Introduction

Astrobe for Cortex-M0 is a fast and responsive integrated development environment for Windows. It is designed to be used to write software to run on the powerful ARM Cortex-M0 family of microcontrollers.  The programming language supported by Astrobe is Oberon. 

Oberon is a general-purpose, procedural programming language. Its type-safety, module consistency-checking and predictable code-generation features allow you to develop efficient, reliable, high- and low-level 32-bit native code embedded software without the arbitrary quirks and complexities associated with using C or assembler.

See the Astrobe for Cortex-M0, M3, M4, M7 Feature Matrix on the Astrobe website for a full summary of features.

8. Acknowledgements

We greatly appreciate the valuable support and encouragement that Niklaus Wirth gave to us during the initial development of Astrobe. He provided us with the original Oberon source code of the ARM compiler, linker, MAU and FPU libraries that formed the basis of the corresponding components of Astrobe and allowed us to include the Oberon Language Report with distributions of Astrobe.
