MicroPython
Python implementation for microcontrollers and constrained systems
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. The MicroPython pyboard is a compact electronic circuit board that runs MicroPython on the bare metal, giving you a low-level Python operating system that can be used to control all kinds of electronic projects. MicroPython is packed full of advanced features such as an interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling and more. Yet it is compact enough to fit and run within just 256k of code space and 16k of RAM. MicroPython aims to be as compatible with normal Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system. -

QP Real-Time Event Frameworks & Tools
Real-Time Event Frameworks based on active objects & state machines
QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows. -

Battery Optimizer
Helps to improve the life expectancy of an electronic device's battery
The creation of this device is in response to the overcharging issue that electronic devices with lithium ion batteries face. Most electronic devices when charged to 100 percent will continue to receive power from their charger, overtime this will slowly degrade the life expectancy of the lithium ion battery in the electronic device. The Battery Optimizer aims to increase the life expectancy of a lithium ion battery in an electronic device by automatically stopping power being fed to an electronic device when the battery has reached a set threshold. Some companies do this with their devices but are usually proprietary. -Lenovo does this with some of their laptops -Company called "chargie" already doing this for phones. Using this device, it will provide universality. For the first iteration of this device, I chose to focus on laptops. I hope in the future to make an app for phones to connect to the device as well. -

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

ArduEMS-328
Arduino Engine Management System
This project is based on the original open source MegasquirtAVR, which became the closed source commercial product known as VEMS. There is a full copy of the original website in the Downloads section. It has the same features as Megasquirt 1 and can be tuned in MegaTunix, MegaTune or TunerStudio as a Megasquirt 1 B&G2.0-3.0. The code is compiled for the ATmega328p so the supported boards should be: - Arduino Uno - Arduino Duemilanove - Arduino Diecimila - Arduino NG - Arduino Extreme v2 - Arduino Extreme Note: only tested on Arduino Duemilanove No schematics are available yet, but please have a look at the MegasquirtAVR schematics. It is meant for the ATmega128 so not pin compatible. -

Open Event Machine
An event driven processing runtime for multicore
Deprecated - see new repository in GitHub instead: https://github.com/openeventmachine/em-odp Open Event Machine (OpenEM or EM) is an architectural abstraction and framework of an event driven multicore optimized processing concept originally developed for networking. It offers an easy programming concept for scalable and dynamically load balanced multicore data plane applications with a very low overhead run-to-completion principle. EM can run on bare metal for best performance or under an operating system with special arrangements. This release of the Open Event Machine contains the EM API as well as an example implementation for Intel multicore CPUs. !!! NOTE !!! Release version numbering scheme changed: after v1.5 follows v1.1.0, where 1.1 reflects the used OpenEM API version. -
