DruidBSD is a FreeBSD micro-distribution that supports CD/DVD, USB, and HD booting into a Live BSD Distribution.
ext2/3/4 library for microcontrollers
The main goal of the lwext4 project is to provide ext2/3/4 filesystem for microcontrollers. It may be an interesting alternative for traditional MCU filesystem libraries (mostly based on FAT32). Lwext4 may be used with SD/MMC card, USB flash drive or other block based memory device. However it is not good for flash memory–based storage devices. Code is also available on github: https://github.com/gkostka/lwext4 Feel free to contact me: email@example.com
The Carmedia Front-End project aims to develop a fully featured and open-source front-end for in-car integrated computers.
FAMOUSO is an event-based publish/subscribe middleware written in C++ for systems ranging from 8Bit micro-controllers up to 32Bit PC/Workstations.
interp is a powerful programming language, a testing platform, and a development framework. It is targeted for Linux/Unix-based systems, yet remains adaptable to less powerful embedded systems that were never intended to host a programming language.
Lightweight matrix lib, especially good for micro-blaze or other embedded processor which needs to do matrix operations. Supports Add, Subtract, Multiply, Transpose, and Invert (Cholesky Method). Compiles to 15kbs using -0s and is ISO C compliant.
State machine framework for reactive embedded systems
RKH is a generic, flexible, modular, highly portable, ANSI-C compliant, and open-source development tool for implementing hierarchical state machines based on modern state machine concepts. This modern techniques are used to give an abstract description of the dynamic behavior of a system in a substantial manner. The RKH not implements neither entire UML specs. nor entire Statechart specs. Instead, the RKH intention is to support just enough basic concepts of that powerful tools to facilitate the reactive-system modeling holding a solid, and efficient implementation. Broadly speaking, the RKH implementation has been designed from the ground up to be used in 8-bits platforms but can be easily adapted to 16 or 32-bits platforms.
A project collecting free software modules which can be used together in an arbitrary microcontroller application, starting with AVR platforms.
