The rumors of the death of Forth have been greatly exaggerated ;-)
I have been maintaining a Forth documentation site for Mecrisip-Stellaris
http://hightechdoc.net/mecrisp-stellaris/_build/html/index.html since around 2014 and it gets about 80 - 100 unique hits a day.
Mecisp-Stellaris caters for ARM Cortex-M while Mecrisp caters for MSP-430.
There is also a Mecrisp-Quintus for RISC-V and PIC32, a Mecrisp-ICE which is an enhanced version of Swapforth and the J1a stack processor by James Bowman.
Mecrisp-Across is a tethered Forth for the MSP430, which uses a Ti Tiva Connected Launchpad as the cross-compiler and a 4 wire JTAG umbilical. The target MSP430 MCU does not use any preloaded firmware, and will run with only 500 Bytes of Flash, appearing to have a full Forth on board with 64KB of Flash.
http://hightechdoc.net/mecrisp-across/_build/html/index.htmlI have also started doing a few YouTube videos to demonstrate that Forth is keeping up with the times and also because there just aren't a lot of Forth videos around.
https://www.youtube.com/watch?v=kDi-Nlz3-QA. They are pretty basic videos and not up to the high standard of eevblog, so don't expect too much!
I mainly use the STM32F051 for all my projects and examples as it's cheap, fast, tiny and immensely capable.
