To begin Rtos with keil

arjun pal

Hi all,
Happy new yr.
I want to go for Real time coding for my applications.
Can anybody guide me to begin with RTOS,so that i can develop applications using Keil RTOS for Microcontrollers,Keil provide help documents but they are too early to begin without basic concept in RTOS.
Thanks in advance.
Regards
Naresh

    I'm using RTX tiny for C166. For C166 information about RTX/RTX tiny are in the the Assembler Manual. See the simple rtx examples, then the "traffic"-example and make some experiments. For RTX tiny 166 the answers are:
    1)
    The first task (task 0) should initialise the system. Create the other tasks. Then terminate task 0 with the os_delete_task(0) command.
    2)
    The task switch interrupt has the lowest priority, so the other interrupts will stop task switching.
    3)
    You will find this in the asm-manual. It is possible to change the rtx-timer if need to do.
    4)
    I don't think that this is possible. What settigs do you want to change?
    In RTX tiny (round robin!) task switches occur after a predefined time. After a short time the program execution continues at this point.
