Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M, STM8. 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.

Super lightweight task scheduler aimed at 8 bit AVR ATmega micro-controllers (perfect for Arduino), although it can easily be used on other hardware like Microchip PIC. 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 Project "WDT Driver for LPC1114 on FreeRTOS" was my Project work required for the partial Completion of my Post Graduate Diploma in Embedded System Design at Center for Development of Advanced Computing, Advanced Computing Training School, Pune, India. 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 embedded Single Timer Wheel (eSTW) is a timer wheel facility that can be used at task and interrupt level. The number of wheel spokes is user configured. The timer granularity is determined by the task signal or hardware interrupt source.

This project designs the oswrap including task scheduler, timer, semaphore, mailbox, wait, memory key components. Support Linux and windows platform and distributed system.
