Hello everyone, this will sound like a self-promotion topic, but i am not here to sell anything to the community, more to offer something ^^ The lastest release (v1.2) of picoRTOS is out
We created a very small, fast, hard real time scheduler and we recently added support for the avr5, avr6 and cortex-m3 platforms. We quickly tested it on arduino mega 2560, uno & due.
The demos for these boards are available in the source code of the project.
The project is not a hack project, it is a serious one that has real life application in automotive ECUs, so if you want ot learn how a RTOS works, this project might quite educational too.

Thanks for your attention
