	~~TODO How~~ to ~~port project from other RTOS~~ -->		In common situation embedded application would call list of functions in a while loop and interrupt service routines are used for critical operations.<br>
			Using RTOS for the same application would make developers life easier and would save power consumption.
			Each function in a list of while loop can represent the task and started only when something really happen. Most of RTOS available today would use priority controlled round-robin scheduling. Where the tasks require different response time developer could assigned different priorities for those tasks and scheduling according to those priorities. Tasks with the same priorities are scheduled using round-robin.

			This is where OCEOS is different.
