Forum Post: RE: TMS320F28379D: Counting Periods of an ePWM wave. Better to use Counter-compare and Event-trigger submodules or the eCAP Module?

Hi, You can use eCAP in APWM mode for PWM output generation. But that will not have High-resolution. For your application, since you wanted fine adjustment of Duty, you should use ePWM/HRPWM module and NOT eCAP.
