For information, PICos18 v2.00 was released.
It is an RTOS for PIC18 series in GPL.It is a realy full preemptive kernel based on the OSEK standard.
in the web site, www.picos18.com ,you will find all source code and an online tutorial.
use the forum, www.picos18.com/forum, for any question.
I couldn't understand anything from PICOS18_API.pdf, because it's fully in french. Due to the fact that I don't able to use this RTOS. If you want peoples to use your rtos , you must translate your documents to english.
Thanks for this remark.
The on-line tutorial is available in French and also in English.
So the document you reference should be one of the last in French only. It should be also the less importante.
