Hello,

In my opnion best book to introduce oneself with conecpts of RTOS & multitasking is
"μC/OS, The Real-Time Kernel” of Jean J. Labrosse" & to see how to apply RTOS to real problems the "Embedded System Building Blocks of Jean Labrosse.

Also it is better to actually write some code & experiment to really understand RTOS concepts.
You can simply download the port of uC-OS-II for your micro from official site.

I was just gonna say that

if you are looking for the concept, then go to one of the books above, for the implementations, I suggest FreeRTOS, it is very efficient, simple, and the online documentation is very simple and very powerful, go to www.freertos.org

hope this helps
