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. ...

Goal: test of tech01 portability to armv7m architecture Target board: NXP FRDM-K28F

CTREE is a command line utility providing analysis tools useful to software engineers tasked with tracking down problems or verifying a program's soundness. It is also an aid to understanding the structure of unfamiliar programs. As it works with standard C it finds most of its utility in embedded systems and older software. CTREE comes with a comprehensive manual. CTREE is is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative...

...It uses simple round-robin scheduling so no priority levels can be set. You choose the time interval by calling dispatchTick(), this is usually in a timer interrupt. Range for number of tasks: 0 to 255 tasks Range for delay: 0 to 65535 ticks Each task only uses 5 byte of RAM. The one task LED blink example only uses 5 bytes of RAM and 476 bytes of program memory for the whole program.

...Each task is activated either to be run in parallel (fork) with other active processes in the system or subordinated to the caller task, thus blocking it and creating a hierarchy of tasks. Execution of processes can be preemptive or non-preemptive and, among those with the same priority, a round-robin turn is performed. This operating system can be used to illustrate these concepts and can also be used to suport the execution of some embedded systems.

...The Duration of the Project was 15-20 Days wherein we had to develop the driver library for the Watchdog Timer on LPC1114 and incorporate the same into FreeRTOS. The services of the driver are exported using the UNIX like read, write, Open and ioctl system calls used by the various tasks in the FreeRTOS environment to register with the Watchdog service. The Watchdog service itself is a task running as an idle task hook and services the watchdog on behalf of all the tasks that are registered with our driver. The driver would reset the system if any of the registered tasks do not perform as they should. This is a student Project, a team of 5, There are some corner cases here and there which would be eliminated gradually.

LabMonkey is a collection of designs for embedded devices which can be networked together to provide a range of automation, data logging and signal processing functions. A key design objective is to use as little dedicated hardware as possible for communication between nodes in the network, and to be able to adapt the network topology in real-time so as to minimize the occurrence of collisions between packets. To achieve this, a protocol has been designed specifically for the task, and...

MikroConf is a command line administration interface for Linux-based embedded systems (linux/uclibc/busybox), which can be easily extended with new administration modules using the Tcl programming language.

A set of tools to generate and build a customized initramfs, for simple mounting tasks, such as setting up a unionfs system. Written for a small footprint and fast execution. Compatible with both glibc and uClibc.

A lightweight, simple and easy to use embedded system task scheduler. RataOS is written as a high level C, with a simple HAL & API structure, allowing it to be ported between embedded devices easily.

The goal of Gossamer is to provide a set of libraries & tools for distributed, fault tolerant, computing. This is done by breaking tasks up into small units which are then processed by seperate servers, which may reside locally or across a network.

...The source code is available in the SVN repository: https://sourceforge.net/p/xrt/code/6/tree/trunk/ and consists in two folders: 1) /X-RT : A portable multiprocessor scheduling framework supporting scheduling periodic real-time tasks according to the G-EDF (Global Earliest Deadline First) scheduling platform. Current version supports major POSIX systems (Linux, QNX). 2) Hardware_GEDF_Scheduler: is a hardware implementation in VHDL (targeting FPGAs) of the G-EDF multiprocessor scheduling policy.
