    three phase motor control

    ardamina.2017_2462821

      i need to create 6 signal that drive a three phase bridge  with a frequency =3600hz

         

      i can do it by timer and a switch case like :

         

       

         

       

         

      but when i use serial to contact with pc and send a frame , the interrupt to timer wait until the frame is send , so the frequency is not fixed.

         

      how to implement it without using CPU to change the port case . like PWM that working without CPU assistance؟
