hi everyone!
I am exploring CCS RTOS and I want to understand it's internal construct as scheduling algorithm, whether preemptive or no, message queue...But I can not find out this.
If you have the document for this. Please help me to do this.

Have you tried just reading the manual.....
The compiler manual is available for download, and describes the RTOS.

It is a co-operative multi-tasking system. It would be almost impossible to implement a pre-emptive system in the architecture of the PIC which lacks a register stack.

In the manual you will see a basic description of the RTOS, and the functions it offers (including rtos_msg_poll, rtos_msg_read, and rtos_msg_write, which answers the 'message queue' question).

So, RTFM.

thank you everyone!
I can understand that you say. Exactly, I am young quite. I am a student in Vietnam.
I learn English myself.
come back my Problem with CCS RTOS. I already read the manual and can use it quite well. but I need more information than that. because I want to build own my RTOS. so I need the support of anyone to reduce time.
