Hi Surya,

Please check F28377S device technical reference manual(TRM) for information on Comparator Subsystem(CMPSS).

You can find examples for using the CMPSS in C2000Ware in the device specific folders. Refer to the example to understand on how to use CMPSS. Please let us know if you any more information.

Thanks,
Katta

Hi Surya,

EPWM can be used here. But I would like to know in detail about your whole query. Do you face any issue in using CMPSS or EPMW?
Please refer to this post if it is relevant to you.

Please mention the full query in a similar fashion of the post.

Thanks,

my query is much simpler i just have to access the output (square -pulse signal ) of the comparator , when compared with two inputs , 1- a constant error signal and 2- a triangular pulse

Hi Surya,

VDDA should be supplied 3.3V as nominal. For more information check these posts
