AmForth is an interactive 16-bit Forth for Atmel ATmega and Texas Instruments MSP430 microcontrollers. It does not need additional hard or software. It works completely on the controller (no cross-compiler). AmForth uses the indirect threading forth implementation technique. ATmega: The forth dictionary is in the flash memory, new words are compiled directly into flash. Since no (widely available) bootloader supports an API to write to flash, AmForth uses the bootloader space itself. MSP430 The Forth dictionary is in the flash or FRAM memory, new words are compiled to it. Use SAVE to keep the code accessible across reboots. The flash devices cannot rewrite the flash cell once a word is written. AmForth is implemented in assembly and forth. The code is stable and well tested. The MSP430 variant is newer and may have less features. All words have Forth 2012 (CORE and various extenion word sets) stack diagrams, but not necessarily the complete semantics. Some words from the standards are left out, ask for them if you need them. Development hardware are evaluation boards running various Atmega's between 2 and 20 MHz with various external hardware: none, led, push-buttons, SD-card, ethernet controller, RF module etc. The MSP430 code is tested with Launchpads.
