amforth is an extendible interpreter on microcontrollers
amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. Turnkey actions for fully autonomous operations are possible as well. The command language is close to the Forth 2012 standard.
colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."
