the number of tasks

Jian Wang

I am debugging some source code with Keil uv3 IDE. We are using ARTX for ARM. My question is how can I find out the number of tasks managed by the RTOS?

Thanks

    Jian,

    I don't use the Arm compiler, so what follows is unlikely to work for you, however here we go:
    - the debugger can tell you right away how many tasks are running, plus much more information. It should be part of the "peripherals" menu.
    - if you want your own program to know how many tasks are running, a good place to start looking is os_active_TCB[].

    I imagine that a piece of code like:

        #include "blah...\AR166\SRC\Kernel\AR166_Config.h"
    #include "blah...\AR166\SRC\Kernel\AR_C_Interface.h"
    unsigned int NumberOfRunningTasks = 0;
    for (i=os_maxtaskrun; i--;)
    {
        if (os_active_TCB[i]!=PNULL)
        {
            NumberOfRunningTasks++;
        }
    }

    Should get you near what you want to do.
