Cortex-M7 Feature Matrix

This table summarises the features of Astrobe for Cortex-M7 included in each of the available editions. Further details of the features can be found in the documents titled "Oberon for Cortex-M7 Microcontrollers" and the "Oberon Programmers Guide" which can be downloaded from the Oberon page.

Multi-file Editing Professional Personal
  • Standard Windows, programmer-oriented, text-editing features
  • Fast and responsive interactive operation
  • Tabbed multi-document interface for editing multiple source files (modules)
  • Split-screen editing
  • Regular expression support in Find / Replace
  • Bookmarks
  • Line modification indicators
  • Optional line numbers, printing features etc. etc.
  • The module in the current window is the target of the compiler / linker / builder
Oberon Language-oriented Editing
  • Automatic syntax colouring of language elements as you type
  • Auto-capitalisation of keywords as you type
Code Navigation
  • Alphabetical auto-indexed list of procedures. Click on the name to go to the procedure in the source code.
  • Auto-indexed list of imported modules. Click on the module name to open the file.
Language Features
  • Conforms to the 2016 Standard Oberon Language, including 32-bit IEEE REAL data type and operations
  • Leaf procedures use registers for parameters and local variables for optimum performance
  • Interrupt procedures
  • Local dynamic array language extensions for safe memory allocation / deallocation
  • Low-level SYSTEM functions GET, PUT, ADR, BIT etc. for accessing the MCU control, status and peripheral registers
Fast Native-code Compilation
  • Fast single-pass modular compilation
  • Generates 32-bit IEEE Cortex-M7 hardware floating point instructions for add, subtract, multiply, divide and square root
  • One-click to compile the module in the current window
  • Only the current module needs to be compiled if the interfaces of imported modules are unchanged
  • Pre-compiled symbol files are used for fast access to imported modules
  • Compilation continues to the end to find as many errors as possible
  • Compilation errors are displayed in a separate window
  • Click on an error line to take you to the actual line in the source
Linking / Building
  • Creates compact and fast 32-bit native-code applications
  • Automated Build feature identifies and recompiles all outdated modules before linking
  • There is no need to maintain separate 'make' files. The names and locations of imported modules are already known at link time.
  • Interfaces of imported modules are validated at link time to ensure consistency and eliminate obscure runtime errors
  • Compile, link and build options are stored in configuration files
  • Multiple projects for the same target can share a single configuration file
  • Configuration file settings for multiple library search paths
  • Configuration file settings for application code, data, stack and heap addresses
  • User-customisable Tools menu to launch Windows applications or command-line utilities of your choice from the Astrobe menu
Debugging and Error trapping
  • Language support for validation of procedure parameters, pre- and post-conditions using assertions
  • Automatic array index bounds checking
  • Runtime library Out can be used to send trace output to the Astrobe terminal window via a UART serial connection
  • Runtime errors and failed assertions are identified by a callback trace with module and procedure names and source line numbers
  • Source code of the Traps runtime library module can be user-customised
Uploading and Running
  • No special hardware programming tool is required
  • Upload via USB drive for mbed-enabled boards
  • Integrated terminal emulator communicates via a UART with a program running on the target device
  • BIN and HEX-format files allow you to program target devices using 3rd-party tools e.g. ST-Link.
