Hi experts

1. How to achieve controlled output of ePWM pulse count
2. PWM processing encoder signal as input count, is handled through DMI or interrupt?

    Hi Ethan, just confirming you are using AM62x 9.2 MCU-SDK, right? If so,

    1) Please check our MCU-SDK examples and let us know if there is a particular configuration that you need. EPWM examples' path: C:\ti\mcu_plus_sdk_am62x_09_02_00_38\examples\drivers\epwm 

    2) From C:\ti\mcu_plus_sdk_am62x_09_02_00_38\examples\drivers\epwm\epwm_duty_cycle\epwm_duty_cycle.c I see we are using interrupts. I will check with our developers if DMA example for EPWM running on M4 is in current roadmap.

    thank you,

    Paula
