Then your microcontroller code needs a redesign. Otherwise you're just turning you general-purpose computer into nothing more than a dumb "microcontroller" that iterates over unneeded code repeatedly, hence the 100% cpu. Another symptom of you using your computer incorrectly is the fact that your hardware motor's speed depends on the speed at which you send commands to it via the serial interface. You need to "command" it with the computer which will host your high-level logic. And your micro-controller needs to handle the low-level, repetative control of the motor.
