VGAVR is a program that provides an 18x19 text mode on 16MHz Atmel AVR microcontrollers using the 640x480@60Hz industry standard screen resolution. The rendered image is based on an ASCII text buffer and updated in real-time. The font is stored in program memory, so the SRAM usage is less than 400 bytes.
sVimPy is a very small Python virtual machine intended for use in microcontroller projects. At the moment, it supports about 3/4 of all opcodes used in python3k. Most data types are supported. The intended goal is to use this VM in environments like Atmel's ATmega chips (2-8kb RAM). The microcontroller bootloader is still missing (no arduinos left for experimentation). Classes are not supported. Features include: function calling, a stack based VM, garbage collection, very low memory usage, an interactive debugging console, dictionaries and tuples, iterations, VM single stepping (game loop usage is possible), C function calling, a small memory footprint, fast performance, the ability to be used as a library in other projects, a simple API + code, possible usage as a small deployment executable for Python projects.
