This is the 64th release of amforth in more than 10 years development. It does some fine-tuning of the I2C library on the AVR platform. There is now code to use amforth as a I2C slave. Furthermore it adds the 'c' number input format and support for program specific stacks. "under the hood" are many small improvements and code simplifications. A lot of previously hidden words or words that were intended for testing purposes only are now available for user programs. Atmforth is a 16bit Forth system designed to run on AVR Atmega and TI MSP430 microcontrollers. It is written in highly optimized assembly and Forth itself, most of the core system shares the same source code. The core system fits into 8KB of code space. It allows access to all controller specific features including support for Harvard architecture specific things like multiple address spaces of memory (EEPROM, flash, RAM). The Forth interpreter compiles directly into the flash (or FRAM) memory. Amforth supports most features of the Forth 2012 standard and has a few enhancements over it like recognizers.
