    Hi Maheswarappa,

    I would recommend taking a look at the ePWM examples within controlSUITE.  controlSUITE is C2000's repository for C2000's code examples and libraries.  It can be downloaded and used for free. These ePWM examples can be found at:
    \controlSUITE\device_support\f2833x\v133\DSP2833x_examples_ccsv4\

    Inside controlSUITE you can also find a code example for how to run the TMDSHVMTRPFCKIT motor control kit with the F28335 controlCARD.  Even if you don't have the kit, you may find the software useful.
    \controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVACI_Sensorless_2833x\


    Thank you,
    Brett

    Hi Mahesh,

    You can refer SGEN library that can be found here:

    C:\ti\controlSUITE\libs\dsp\SGEN\v101

    Do read the documentation first: C:\ti\controlSUITE\libs\dsp\SGEN\v101\doc
