how to check ?

Hi ,

I did the following example using F28335 evalution kit.for this example where i have to check whether interrupt generated or not.

 

This example configures the ePWM Timers and increments
  a counter each time an interrupt is taken.
    As supplied:

    All ePWM's are initalized.  Note that not all devices in the 2833x
    family have all 6 ePWMs.

    All timers have the same period
    The timers are started sync'ed
    An interrupt is taken on a zero event for each ePWM timer

       ePWM1: takes an interrupt every event
       ePWM2: takes an interrupt every 2nd event
       ePWM3: takes an interrupt every 3rd event
       ePWM4-ePWM6: take an interrupt every event

    Thus the Interrupt count for ePWM1, ePWM4-ePWM6 should be equal
    The interrupt count for ePWM2 should be about half that of ePWM1
    and the interrupt count for ePWM3 should be about 1/3 that of ePWM1

 

and i am not understanding EVENT TRIGGER SUB MODULE,can anyone help me by giving small explanation abut this?

and where it is used?

thanks & Regards,

Naveen Rangu

    A full description of this or any module is too long and detail to fit in this forum discussion. My suggestion for you is to download ePWM manual and go through various blocks to have an initial understanding of the device. There should be some online training material as well - please contact TI hotline for a reference.
