I already searched for rs233 and made max232 circuit and there is rs232 code in fpga4fun
Please help me.
I need code for servo motor. I want to turn it 180 degree and stop 0.5 every 30 degree.
I will add state diagram for servo.

Here the basic state diagram for servo



I have 2 week to do this. Unfortumately last week is exam week...

Is it a servo similar to the type used in radio-controlled planes, etc?

Then you send it pulses which vary between 1 and 2 milli-seconds. The motor automatically turns to match the signal.

Example, send 1.5 mSec pulses to make it turn to the midway position.

A typical frame rate is 50 times per second.

A PWM pulse generator comprises of

1. Counter - the width of the counter control the PWM frequency (The wider the counter the slower the frequency)
2. Comparator - the running counter value is compared to your position value. This determined the duty cycle of your signal.
