    user5269312,

    If you want to make an interrupt with a regular period I can think of 2 good ways. Either way, you should be able to find examples in C2000Ware.

    1. Use a CPU timer.
      1. C:\ti\c2000\C2000Ware_2_00_00_02\device_support\f2833x\examples\cpu_timer
    Use a PWM with a period equal to 3.3 mS or optionally you could use the ETPS[INTCNT] register to filter the interrupts and use a PWM period that is an integer multiple of 3.3 mS.
    1. C:\ti\c2000\C2000Ware_2_00_00_02\device_support\f2833x\examples\epwm_timer_interrupts

    Regards,
