Mecrisp-Cube

Mecrisp-Stellaris Forth for the STM32 Cube ecosystem. The STM32WB Nucleo Board is working out of the box yet. See also Mecrisp Cube.

Getting Started

These instructions will get you a copy of the project up and running on your local machine (STM32 Nucleo board) for development and testing purposes.

Prerequisites

  • One of these boards
    • STM32WB Nucleo Board - The highly affordable STM32 Nucleo boards allow anyone to try out new ideas and to quickly create prototypes with any STM32 MCU. The STM32 Nucleo boards integrate an ST-Link debugger/programmer, so there is no need for a separate probe.
    • STM32WB5MM-DK Discovery Kit - complete demonstration and development platform for the STMicroelectronics STM32W5MMG module.
    • STM32WB Feather Development Board - The STM32WB Feather Board is a development board based on the Adafruit Feather standard with the STM32WB Bluetooth SoC at its core. This board specifically uses the STM32WBCGU6. It includes all the basic functionality you need to get up and running quickly.
    • STM32F405 Adafruit Feather Express Board - ST takes flight in this Feather board. The new STM32F405 Feather that we (Adafruit) designed runs CircuitPython (and Forth) at a blistering 168MHz – our fastest CircuitPython board ever! We put a STEMMA QT / Qwiic port on the end, so you can really easily plug and play I2C sensors.
  • Terminal emulator application for PC, e.g.:
    • PuTTY - Windows and Linux
    • Tera Term - Windows
    • Realterm - Windows
    • minicom, microcom, screen - Linux
    • Use the built in Eclipse console (but no LF)

Flash the Mecrisp-Cube binary to the Nucleo Board.

  1. Connect the Nucleo Board USB ST-LINK to the PC
  2. Copy binary (MecrispCube.bin) to the USB mass storage NODE_WB55RG. Or even better the binary with tools and drive.

For other boards see https://github.com/spyren/Mecrisp-Cube/branches

Start the terminal emulator application on the PC. Check for the serial communication port (e.g. for Linux /dev/ttyACM0) and set the speed to 115200 baud. I set the putty terminal configuration to

  • Implicit CR in every LF
  • Local echo: Auto
  • Local line editing: Auto

Installing

A step by step series of examples that tell you how to get a development env running

Install the IDE STM32CubeIDE, it is Eclipse and GCC based. STM32CubeMX is included in the IDE, you need a stand alone installation only if you do not want to use the STM32CubeIDE.

Get the sources from github:

psi@homer:~> git clone https://github.com/spyren/Mecrisp-Cube
Klone nach 'Mecrisp-Cube' ...
remote: Enumerating objects: 106, done.
remote: Counting objects: 100% (106/106), done.
remote: Compressing objects: 100% (71/71), done.
remote: Total 106 (delta 33), reused 106 (delta 33), pack-reused 0
Empfange Objekte: 100% (106/106), 938.96 KiB | 2.39 MiB/s, Fertig.
Löse Unterschiede auf: 100% (33/33), Fertig.

Import the project into the IDE:

File -> Import -> General -> Existing Projects into Workspace -> Select root directory
Copy project into workspace
Browse to Mecrisp-Cube directory

Generate code from the STM32CubeMX MecrispCube.ioc file:

Project -> Generate Code 

Restore changed source files

$ git status
{list of changed files}
$ git restore {files to restore} 

Select the Build Configuration (Debug if you want to debug the project) and Build the project:

Project -> Build Configurations -> Set Active -> Debug/Release 
Project -> Build Project

Built With

  • STM32CubeIDE - STM32CubeIDE is an all-in-one multi-OS development tool, which is part of the STM32Cube software ecosystem. The IDE is used for development, GCC tools are included.
  • STM32CubeMX - STM32CubeMX is a graphical tool that allows a very easy configuration of STM32 microcontrollers and microprocessors, as well as the generation of the corresponding initialization C code for the Arm® Cortex®-M core or a partial Linux® Device Tree for Arm® Cortex®-A core), through a step-by-step process.
  • STM32CubeProg - STM32CubeProgrammer (STM32CubeProg) is an all-in-one multi-OS software tool for programming STM32 products.

The STM tools work on Linux, Windows, and Mac.

Tab size is 4 for C and assembler source files. Append ?ts=4 to the URL to change the tab-size.
