Sonar radar ( altera de0 nano )

[Kaan]

Hello everyone, im working on it privately. I studied hard in lesson. Now have project instead of final exam...
I have 9 lessons also..
Could anyone can help me ?
I have altera de0 nano
2x hcsr04
Digitus rs232 and max 232 circuit
Servo motor SM-S4303R
3.3v to 5v and 5v to 3.3v circuit

Please help me with code
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.

- - - Updated - - -

Here the basic state diagram for servo



I have 2 week to do this. Unfortumately last week is exam week...
Teacher want codes in verilog hdl.
IF you have code for hcsr04 please share with me

I need code for servo motor. I want to turn it 180 degree and stop 0.5 every 30 degree.

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.

I see.
I want to turn my motor 0=> 180 degree and turn start position back.
Do you have any example ?
I worked with other group's members. we wrote code but after all they do not want to give me codes because of my groups members...
I have 10 days left to finish project but after all i have 0..
Need hc-sr04 and motor code..

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.
