CamelForth in C, by Dr. Brad Rodriguez
new feature: no-error getKey()
Reasonably well debugged - functional Forth interpreter.
There was one bug where it crashes unexpectedly, after a decently long runtime. 'getchar()' in the upstream pico-sdk now has a bug report filed.
Port: rp2040, Raspberry Pi Pico target board, February, 2021.
older entries in this README.md, follows (from prior to 17 Feb Wed 16:29 UTC).

CamelForth in C by Brad Rodriguez
A Forth in C by Dr Brad Rodriguez
Forth interpreter for the RP2040 and Raspberry Pi Pico.
UNSTABLE version. Look for changes and improvements here.
New feature: the blink word. Use once per blink.
Requires pico-sdk and is modeled on pico-examples.
The /dev/ttyACM0 is the primary interface (USB).
(Reference host PC is Linux Debian amd64)
Using CP2104 USB-to-USART bridge, the secondary interface (in Linux host PC) is /dev/ttyUSB0, but that is arbitrary (you can bridge using other methods and chips).
Connected to UART0 on the pico.
BUILD ENVIRONMENT - bare bones text interpreter
no Forth functionality at all - not even base code.
Just keyboard echo loop.
