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. -

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. -

WP 34s
Scientific/engineering firmware repurposing HP business calculators!
This project has created scientific firmware for the HP-20b and HP-30b business calculators. WP 34S turns either of these calculators into a powerful keystroke programmable scientific device. According to our customers, it's the most powerful and fastest RPN scientific pocket calculator ever built. WP 34S is alive and stable since 2011. We have succeeded in satisfying the most picky users - read about their experiences on http://www.hpmuseum.org/forum/forum-8.html. Since 2014, WP 34S runs in version 3.3. Our customers confirm its documentation is excellent and comprehensive (see feedback); a full-color printed edition is available from https://www.amazon.com/dp/153366238X since 2018-10-15. Alternatively, you can get a personalized pdf-manual for a ≥ 9 US$ donation here. We have also produced the WP 31S which is derived from the WP 34S source code. This is an entry-level scientific calculator. Its printed manual is available from https://www.amazon.com/dp/1499231164 . -

AWS IoT Jobs library
Client library for using AWS IoT Jobs service on embedded devices
The AWS IoT Jobs library helps you notify connected IoT devices of a pending Job. A Job can be used to manage your fleet of devices, update firmware and security certificates on your devices, or perform administrative tasks such as restarting devices and performing diagnostics. It interacts with the AWS IoT Jobs service using MQTT, a lightweight publish-subscribe protocol. This library provides a convenience API to compose and recognize the MQTT topic strings used by the Jobs service. The library is written in C compliant with ISO C90 and MISRA C:2012, and is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8, and checks against deviations from mandatory rules in the MISRA coding standard. Deviations from the MISRA C:2012 guidelines are documented under MISRA Deviations. This library has also undergone both static code analysis from Coverity. -

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. -

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. -
