    Default squre wave inverter

    Hi,
    i want to convert 12 v DC into 240 v 50 Hz. AC using pic 16f72 in a push pull
    configuration.
    i have to generate software pwm at portb.5 and portb.6 which is used for mosfet firing.
    microchip AN654 is description of similar thing but in assembly which is beyond my understanding .
    there is a feedback voltage to decide the duration of hi period of each pulse.
    i am trying to write but i dont know from where to start and how to proceed.
    i am setting timer0 to generate interrupt at every 10 ms one pin hi for 10 ms while other off . then other hi for 10ms and previous off.
    but how to control the time depending on feedback.
    Can any gentleman guide me from where to start and how to proceed.
    or any link for this.
    thanks and regards

    BTW
    your question has ended up in a completely wrong category.
    This category is actually to request changes to the forum!
