Intro

Changed:

<
< Mecrisp-Stellaris Forth for the STM32 Cube ecosystem.

>
> Mecrisp-Stellaris Forth for the STM32WB family.

Forth is an interactive and extensible language, with built-in lexical analysis (tokenizer, parser) and interpreter/compiler, needs less than 20 KiB Flash and 4 KiB RAM, unbelievable for a self-contained (self-hosted) system.

Forth is perfect for embedded systems where some sort of user interactivity like CLI and extensibility (at runtime) are needed.

Changed:

<
< C & Forth in the 21st Century. C and Forth are both about 50 years old. To combine the strength of this two worlds results in a powerful system that outperforms other much newer systems like Python. Good design withstands the test of time.

The goal of Mecrisp-Cube is to be a complete Forth programming environment for STM32 MCUs.

STM32WB Feather Development Board

Line: 237 to 233

Remove the USB Type A plug from the dongle and add a Adafruit Micro B breakout board. It is convenient to have a Micro-SD breakout board (level shifter is not needed) and JTAG connector (I prefer the 14 pin STM variant to have a serial interface by the ST-LINK). Everything mounted on headers on the backside of FeatherWing Tripler Mini Kit.

21st Century Forth

http://www.forth.org/svfig/21st.html

What's good about Forth

small
easy to understand
extendable
adaptable to programmer
interactive
open compiler/interpreter
simple architecture
source code available
helpful in learning about hardware and software

What's bad about Forth

NIH (not invented here)
cryptic reverse polish notation
difficult to learn
documentation sometimes lacking or unavailable
unconventional syntax
no linkage with other languages
getting more complex
lack of data typing
source (proprietary protection problem)

What 21st Century Forth should be

work in embedded applications
work with networks and Internet
work with large systems (operating systems, graphic user interface)
be able to be taught to programmers and engineers

What Forth needs

reuseable binaries (other languages & headers)
more/better/useable libraries
safety (year 2000)
better documentation
more examples
workable standards
better gui/window editor w/more information
package confidence
more debugger integration
works with newer CPUs (embedded systems, MCU)
publications
big daddy $$$
educational opportunities
more types of multitasking/multiprocessing pre-emtive multitasking

21st Century Forth desires and vision

real/virtual machines/core
scriptmaking (language to taste)
real compile toggle (memory, speed, optimization)
integratable applications
"browser" environment *
environments (such as voice) interpretation (fuzzy)
pda's bases, smart cards, etc
servants (robots, etc) applications
