    three phase motor control

      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؟
