    Hi Saran,

    In short, are you looking for variation in PWM duty cycle with variation in ADC input? You can refer this example to get started with:
    C:\ti\controlSUITE\device_support\f2833x\v142\DSP2833x_examples_ccsv5\adc_soc

    Saran,

    for an example of how to modulate the PWM you can look at <controlSUITE>\device_support\f2833x\v142\DSP2833x_examples_ccsv5\epwm_up_aq.

    You should be able to combine the example Gautam recommended along with the PWM example I provided to get a working solution.

    Regards,
    Cody
