An Integrated Software Development System for ARM Cortex-M Microcontrollers

What is Astrobe?

Astrobe is a complete integrated embedded software rapid development system running on Windows. It includes a multi-file, fully featured, syntax-aware programmer's editor, native code compiler, linker and builder, program uploader and a serial terminal. Use it to develop reliable software to run on the powerful ARM Cortex-M0, M3, M4 and M7 families of microcontrollers.

Install and Go

Installation of the complete system takes minutes from a single setup file. The startup files, library modules and examples included with Astrobe enable you to start writing your applications without having to work from scratch. The source code of these modules is included allowing you to tailor them to suit your specific requirements.

Astrobe has been tested with a range of ARM Cortex-M0, M3, M4 and M7 development boards using STM microcontrollers. No special-purpose hardware is needed to program the microcontrollers with these boards. Astrobe uploads the compiled code to the target from your PC via a USB connection and allows you to communicate with your application in its serial terminal window.

A Modern Language

Astrobe uses the latest version of the programming language Oberon. Its carefully designed features allow you to develop embedded software with efficient, reliable, compiled high- and low-level native code without the complexities associated with other languages.

Reliable Tools

The Astrobe Cortex-M compiler was developed specifically to support ARM Cortex-M targets so it is compact and comprehensible. Unlike other compilers used for these systems, its size is measured in thousands, not hundreds of thousands, lines of code. The end-result is a very robust system and any problems reported are usually fixed within a few days.

Troubleshooting your Code

Astrobe identifies many common programming errors at compile / link time before you even run your program; most others are automatically trapped at runtime. The system automatically identifies the point of failure by module name and source code line number so time is not wasted trying to track down spurious side-effects.

Feature Summaries

Refer to the relevant Feature Summary for a summary of everything that is included in each package:  


Download PDF documentation: the Oberon Language Report, the ARM Cortex-M Oberon Programmers Guide etc.


Try the ready to compile and run source code examples distributed with Astrobe - such as the example code for a simple LED-blinking program. 

Additional source code examples can be viewed and downloaded from the Astrobe forum.

Download Oberon programming text books for source code examples used to solve general programming tasks.

Technical Support

Quick and accurate technical support is vital to the usefulness of any software development system. Technical support is available by priority email for Professional users and on a web-based forum for all other users.
