Now i want to know how amount of time pass during my task...

please help me.

  • Hi Saman,

    I'm not really sure what you time you are trying to get.

    You can use the Clock_getTicks to see a simple timestamp. There is the xdc/runtime/Timestamp module also if you need finer granularity.
    There is the ti/sysbios/hal/Seconds module if you need time of day.

    Thanks for your response.
    I want to know how much time is spent on my main task.
    what about UIA analyzer?

  • In reply to saman mahmoudi:

    You can enable Task load measuring. I would enable Swi and Hwi load measuring to get the most accurate measurements.

    You can look at this thread for how to set it up. Note: you can get the load once Load is enable via
    1. runtime APIs
    2. ROV Tool in CCS
    3. System Analyzer

    The easiest of these is #2.
