hi, everybody!
In the market lots of sine wave inverter available in pic 16f72 they are using software pwm not hardware pwm in the entire forum no body has discuss about software pwm , as 16f72 is very cheap and easily available.
I think we should explore about generating software pwm to create sine wave in a bridge configuration, I am trying to develope it and hope it will be successful in this month after finishing i will be able to put some light on it.
thanks
