Hello All, I need to be able to detect (will be assembly as I have to put this into the tick ISR) the task status – what will make this ‘fast’ is that I only need to know if:

if( pxTCB == pxCurrentTCB )
{
        /* The task calling this function is querying its own state. */
        eReturn = eRunning;
    }

that’s true and I see that’s in the eTaskState funtion. I guess I can start by implementing the assembly version of eTaskState up to that point – but I was wondering if there is any other quicker way to do this and if there’s some other function/macro someplace that does that. Thanks! John W.

Hello All, Well, I figured out a way to do this: … mov xar7, dbl ((#_save_xar7)) ; save xar7 mov xar6, dbl ((#savexar6)) ; save xar6 amov #0x000000, xar7 ; must be cleared amov #0x000000, xar6 mov *sp(#1), ar7 ;; sp+3 mov ar7, *(#_save_new_pxcode) mov ssp, ar6 mov *ar6(#1), ar7 ;; ssp+3 mov ar7, *(#_save_new_pxlcode) ; ==> now we have our new return address, and if a task, it’s where we are

                    mov dbl (*(#_pxCurrentTCB)), xar7
                    mov xar7, dbl(*(#_xCompareTCB))
                    mov dbl (*(#_save_xar7)), xar7                  ; restore xar7
                    mov dbl (*(#_save_xar6)), xar6                  ; restore xar6

And: … .if 1 mov dbl (*(_xCompareTCB)), xar6 ; need to restore our return address
mov xar7, ac0 mov xar6, ac1 CMPU AC1 != AC0, TC1 BCC $5,TC1 amov #0x000000, xar7 amov #0x000000, xar6 mov *(#_save_new_pxcode), ar7 mov ar7, *sp(#0) mov *(#_save_new_pxlcode) , ar7 mov ssp, ar6 mov ar7, *ar6(#0)

                    mov dbl (*(#_save_xar6)), xar6
                    .endif

$5: So, that’s not too bad. Regards, John W.
