mcu

z51dude is a Linux based utility to program a variety of ABOV MC96F* and Zilog Z8051 devices. Together with a simple Arduino based OCD adapter it implements flashing/reading CODE memory, read/write access to RAM, SFRs and OPTION bits.

STM8S Dero (DEv zeRO) Board

An hobby OS running inside an ATmega MCU. It uses a WDC65C02 emulator to circumvent the Harvard architecture limitations and aims to provide a system with a look and feel similar to the early 80's computers inside a modern and easy to build hardware.

A WDC65C02 emulator designed for simplicity,portability and extensivity. It aims to be an opcode interpreter (not cycle accurate) for MCUs and it's the emulation core of the ZerOS project. WDM opcode is used to provide additional high level routines.

Library-free cortex-m4 optimized firmware

Lightweight framework to create shell-like interface for MCU using UART or semi-hosting.

A starting point for AVR (particularly Atmega M328P, not tied to it though) development.
