High Speed Karlsruhe open automotive code initiative
Since the summer of 2010, the FSAE team High Speed Karlsruhe uses Infineon's XC878 to power its electronics. The XC878 is an 8052 compatible 8-bit µC. Our dedication is to 8-bit real time applications, guaranteed by the powerful peripherals of the XC878. This project aims to publish those portions of our code, which may be of use to a wider audience.

JBernstein: Exploration techniques for non-linear constraint checking
JBernstein is a tool implemented in Java that enables to check whether a polynomial constraint holds for all variables within their domain. It is mainly used in the verification or synthesis of cyber-physical systems where the system model is nonlinear. The tool also supports specifications in assume-guarantee style. The underlying algorithm is based on a translation to Bernstein polynomials, and several optimization techniques are implemented to ensure efficiency. Concerning performance, the tool enables to check all examples in the PVS Bernstein testsuite within a second, which can be an order of magnitude faster than some other tools such as QEPCAD or REDLOG. Although JBernstein uses double, it offers automatic error-estimation capabilities (experimental) so that the generated result is correct (the solver may return unknown when the error-estimate is too large)
C-Library for microcontrollers to control SED1531 based LCD's
The GLCD SED1531 Library provides functions to draw pixels, lines, filled- and open rectangles and text for micro-controllers such as the Atmel 8-bit AVR series for (very cheap!) SED1531 controller based graphical LCD's. The library is written with portability to other micro-controllers and compilers in mind; all target specific parts are stored in a separated header file . The included example is for the Atmel ATtiny2313 and AVR-GCC. It is expected that other targets can be supported with minimal effort. A demo of this library can be watched here: http://www.youtube.com/watch?v=TQqIEX8LDhk

ChumbOS Launcher - Native Application Launcher for Chumby
ChumbOS Launcher is a native C application that is designed to break the shackles of the Chumby, so that not only flash applications can take advantage of the cute little colour screen, touchscreen input, rotary encoder and it's majestic Chumby Button. By the way, not that it had too many shackles, don't get me wrong, but the limitation of using only flash widgets on a device having the horse power of a 450MHz full blown computer, seems to me, a bit of a waste and just a bit annoying. So, what does this application do? It enables you to design a simple Graphical User Interface (GUI) which can start and stop other applications on the Chumby.
LED Animation Firmware for Maple/Arduino
The system uses internal databases to store led information such as pin number, target brightness, time at which the brightness should be reached and current program number. When the target is reached the led looks for the next program and get new time and brightness. Leds and programs can be manipulated on the fly, in the program or from serialusb. A very simple task scheduler call the update of leds every 5ms, leaving plenty of processor for other tasks.
Template Virtual COM Port Project
Template Em::Blocks project for the STM32F4-Discovery board as USB virtual com port. Using the standard peripheral library (not the new HAL). No board specific headers are used. Get the driver here: http://www.st.com/web/en/catalog/tools/PF257938
The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the soon-to-be FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.

Free real-time operating system designed for Cortex-M
Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M, STM8 families. It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.

Framework for CAN communication interfaces including code generator
comFramework presents a flexible, widely customizable CAN communication interface for embedded applications; it covers the CAN stack down to the hardware driver. Signal based application code is linked to the frame based HW abstraction layer. The interface imposes easy to fulfill requirements on the integration environment and will fit in most embedded platforms. A powerful code generator auto-codes those parts of the interface, which depend on your specific CAN network databases; particularly the unpack/pack functions for message (de)composition are generated. The high degree of flexibility results from using the template engine StringTemplate V4 by Terence Parr, see www.stringtemplate.org. The engine is fed with the parsed contents of the *.dbc files and can transform the information in nearly any kind of textual representation. Major samples demonstrate how to interface the generated CAN API with dSPACE TargetLink and MathWorks Embedded Coder to support model based APSW design.
The event based Real-Time Operating System (RTOS) for Arduino
RTuinOS, the event based Real-Time Operating System (RTOS) for Arduino, is now hosted at SourceForge. In this revision, 1.0, the event concept has been generalized. Events can now be broadcasted events, semaphores or mutexes. This permits to implement all the usual inter-task communication patterns. Please refer to the user guide and the diverse code samples for details. The second technical change is a complete revision of the makefile. It has been improved in many aspects and it now supports three host operating systems; the RTuinOS samples (as well as your applications) can be built under Linux, Windows and Mac OS. RTuinOS 1.0 is distributed as setup (a ZIP archive), which contains all source files and the complete documentation, also with source files. Building the samples can be started immediately after unzipping and setting a single environment variable. Thank you for your kind interest in RTuinOS.

Open implementation of the x86 architecture
OpenSOC86 is an open implementation of the x86 architecture in Verilog. The current version only implements the 16-bit part (real mode). The processor is a pipelined architecture clocked at 100 MHz in a Cyclone II speed grade -6. Therefore it can be seen as similar to a 486 in real mode. Several peripherals are also implemented in a somewhat minimalistic way, but enough to be able to boot an IBM PCXT compatible bios and MSDOS 6.22. The current implementation is only proven to boot the bios and DOS in simulation. The system is targeted to run on the DE2-70 board. In order to run the system in hardware a SDRAM and SRAM controller need to be added. These are currently in development.
