Question:
Is it possible to generate Complimentary HRPWMs in F28335 ? If so Is there any App note or sample code available ?
Answer:
The high resolution capability is only available on the A channel of each ePWM module. I think there is potential to use the EPWM1A along with EPWM2A to form a complementary high resolution pair as long as you can get them synchronized as needed and can handle any dead-band requirements.
As a side note: For the ePWM type 1 module (found on 2802x/2803x - i.e. Piccolo) we have added the option to output the high resolution 'A' signal on the 'B' output pin. As before only the A signal has highresolution capabilities as it makes it's way through the device - the option is to bring the resulting signal out on the EPWM1B pin.
