  • SystemView events 0-31, timer start / expired

    Hi,

    I want to use

    #define SYSVIEW_EVTID_TIMER_ENTER 19
    #define SYSVIEW_EVTID_TIMER_EXIT 20

    To inform about software timers start/expire events. I'm using freertos 9.0.0.
    I'm able to pass timer ID in SYSVIEW_EVTID_TIMER_ENTER event but it is not possible in case of SYSVIEW_EVTID_TIMER_EXIT.
    Because of it i'm not able to see which timer expired.

    Is it possible to extend some of IDs 0-31, like it is possible in description file for API events (32 - 500)?

    Best regards
    Lukasz Antczak

  • Hi Lukasz,

    TIMER_ENTER should be called when the timer expired and its handler is called.
    TIMER_EXIT is then called when the handler returns.

    So the timer Id is required only for TIMER_ENTER, since on TIMER_EXIT SystemView knows that this must correspond to the last timer entered.

    IDs 0-31 are internal and cannot be modified.

    Best regards
    Johannes
