"zeptoforth" is a Cortex-M #Forth, currently targeted at #RP2040 boards such as the #Raspberry-Pi Pico. Its kernel has versions written in Thumb-1 assembly, for the RP2040, and Thumb-2 assembly, for the #RP2350.

on 02023-07-13oh hey a US$4 #Raspberry-Pi #microcontroller "RP2040" with device and host USB and 264 KiB RAM. The 8-threaded “pioasm” coprocessor for hardware control things like WS2812 interfacing sounds pretty interesting (32 instructions per PIO program, an assembly language with 9 instructions), with a Python implementation using a function decorator ☺
