All reported problems in Astrobe for Cortex-M0, M3, M3 and M7 have been fixed in v9.3. For a summary see What's New in Astrobe for Cortex-M0, M3, M4 and M7

The free v9.3 Starter Edition of Astrobe for Cortex-M0 can now be downloaded on request. It can be used to develop software for development boards with an RP2040 microcontroller (e.g. the Raspberry Pi Pico) in addition to boards with STM32 Cortex-M0/M0+ microcontrollers. The Licensing Conditions and...

The latest v9.3 Editions of Astrobe ARM Cortex-M0, M3, M4 and M7 have now been released. For more details see: What's New in Astrobe for Cortex-M0, M3, M4 and M7 A summary of features, including the differences between the Starter, Personal and Professional versions can be seen here: The Astrobe for...

The minimal build tools that we developed to make the Project Oberon disk images are not suitable for general use. They are undocumented and we are unable to provide adequate support for their use. However, Andreas Pirklbauer has published some build tools which appear to be suitable. Certainly, the...

An Oberon Compiler for the ARM Processor is a detailed description of the architecture of Niklaus Wirth's ARM Oberon compiler that we used as the basis for our first Astrobe (a.k.a Armaide) ARM compilers in 2008. Note that the parameter passing convention is dependent on whether a procedure is decl...

The number of buttons, switches, LEDs etc. supported by Embedded Project Oberon is summarised in the Supported FPGA Development Boards section on the Astrobe RISC5 - Embedded Project Oberon page on the Astrobe website. Although the Nexys A7 board has 16 switches, only 8 are enabled because that is t...

Embedded Project Oberon was designed to be remotely controlled with all of the user interface on the PC. I can't envisage how it might work with the keyboard being isolated from the mouse and display. The question is more appropriate to Project Oberon Workstation. This handles all of the keyboard, m...

Constant expressions are evaluated at compile time. Decimal and hexadecimal INTEGER constants are signed integers and an integer overflow in a constant expression is trapped at compile time. For example: CONST MaxInt = 07FFFFFFFH; (* PosOverflow = MaxInt + 1; Error: integer overflow *) MinInt = 0800...

I can't think of a general way to copy the executable code of a procedure to RAM that would be both useful and reliable in the current implementation of Astrobe for Cortex-M. Note that Astrobe for RISC5 supports the dynamic loading of modules (but not isolated procedures) into RAM. What is the actua...
