hi,

I am looking for a example of TI which contains a PWM with variable duty cycle, which example should i use?

ePWM slider or hrpwm-duty?

    For this device I suggest looking at the example "epwm_updown_aq_cpu01". If you have C2000Ware installed at the default location, this will be at:
    C:\ti\c2000\C2000Ware_1_00_04_00\device_support\f2837xd\examples\cpu1\epwm_updown_aq

    Just to point out that varying the duty cycle does not change the PWM frequency. I only mention this because of the post title.

    Regards,
