ChibiOS Free Embedded RTOS

Ok. Thanx for the info.
I will check the arduino forum. AFAIK he is fat16lib over there...

Small update

I did some small / simple experiments on a 32u4 and Arduino IDE 1.04 / 1.05 and must say that I like NilRTOS alot!
At first I used the february libraries Bill made for AVR. This morning I saw that Bill already made some changes to the AVR port due to changes in IDE 1.05. Nice!

I do ...

I've read some of the ChibiOS documentation and see that this OS has a lot of sync/event possibilities.
The event mechanism (single/multiple events) is very nice, but if I look at the code, it also looks rather a 'huge' addon considering ROM/RAM...

Is it possible that nilRTOS will support adding ...

Thanx for that update, Giovanni!

As for the other questions (device/library compatibility), are you able to answer those questions, or should Bill Greiman do that

I just stumbled by accident on NilRTOS and this wonderfull Arduino port

Looking at the examples I truly hope that the development of this OS for Arduino continues!

I did try some sketches using Quantum Leap's State Framework (QF), but got lost in complexity and rework of very simple existing ...
