PWM generation with eCAP modules - TMS320F28335

Other Parts Discussed in Thread: TMS320F28335

Hi,

I am trying to generate complementary SPWM signals for a three phase inverter using the eCAP modules for TMS320F28335.

For some reason my code does not change the duty cycle of the PWM signals. Does anybody have such a code so that I may use by modifying?

Thanks

Have you checked the example projects which used to come with header file installation? There used to be a project on generating PWM output using eCAP module. Check your installed example projects .....

Yeah I did, actually I am using that program as a template, but I want to vary the duty cycle according to a sine reference.

I need to run an ISR which I have written in the code. For some reasons, it does not execute the ISR.
