AVR ATmega port of freeRTOS A port of freeRTOS which can be flexibly flexibly configured use almost any available Timer on AVR ATmega devices and will operate with almost any classic Arduino device from Arduino, SeeedStudio, Sparkfun, Freetronics or Pololu. Going forward this repository will be updated less often and only with major releases. Please check at Github for the latest commits. https://github.com/feilipu/avrfreertos The Goldilocks Analogue story is told here....

...It presently supports the AVR and MSP430 architectures. The advantages of PRTOS are: It has the smallest footprint of any true preemptive system: 1.9kB for basic scheduling and task control, 5.1kB with all the features below (AVR '328 / gcc -Os); Only 950 lines of code implement all of the RTOS features (SLOC-L); The system is well documented with a comprehensive manual, well-commented source code, and a test suite demonstrating the features; The system is proven - it has been in use since 1982 with applications in in-vitro medical equipment, process control instrumentation and industrial machinery; PRTOS is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative RTOS https://sourceforge.net/projects/cortos-simple/ and the CTREE analysis tool https://sourceforge.net/projects/ctree-graphic-tree-generator/ Commercial licensing is available

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 one task LED blink example only uses 5 bytes of RAM and 476 bytes of program memory for the whole program.

...Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.

K-OS is an open-source realtime-operating-system based on the OSEK/VDX standard aimed at compiler and microcontroller independence. Currently we support Motorola (Freescale) HC12/HCS12/HCS12X targets.
