Arduino and X-Sim

Hi everyone. I am also trying do it with arduino.

I had a little time and play with PID library. I write code that simulate controlling one motor. I change PID library from Arduino site. I think this is good code. What are you think about it?

Code:

#include <PID_v1milos.h>

/********************************************************
 * PID Basic Example
 * Reading analog input 0 to control analog PWM output 3
 ********************************************************/



//Define Variables we'll be connecting to
double Setpoint, Input, Output;

int i;
int Gforce = 0;
int Gforce1 = 0;
int Gforce10 = 0;
int Gforce100 = 0;

PID myPID(&Input, &Output, &Setpoint,2,0.05,0.25, DIRECT);

void setup()
{
  //initialize the variables we're linked to
  Input =90;
  Setpoint = 90;

  //turn the PID on
  myPID.SetMode(AUTOMATIC);
  Serial.begin(9600);
}

void loop()
{
  if(Serial.available() > 0)
   {
     char tip;
     tip=Serial.read();

    delay(2);
    int Gforce100 = Serial.read()- '0';
    delay(2);
    int Gforce10 = Serial.read()- '0';
    delay(2);
    int Gforce1 = Serial.read()- '0';
    
    if (Gforce1 < 0) { Gforce = Gforce10 + 10*Gforce100; }
    if (Gforce1 < 0 && Gforce10 < 0) { Gforce = Gforce100; }
    if (Gforce100 < 0) { Gforce = 127; }
    if (Gforce1 >=0 && Gforce10 >= 0 && Gforce100 >= 0) { Gforce = 100 * Gforce100 + 10 * Gforce10 + Gforce1; }
     
    if(tip == 'p') //simulate reading potentiometer value with manual inputting potentiometer value in console in format pxxx
    {
        //i=0;
        Serial.println(InputX:  );
        Serial.println(Gforce);
        Input=double(Gforce);
    }

    if(tip == 's') //simulate setting new setpint value from PC with manual inputting  value in console in format sxxx
    {
        Setpoint=double(Gforce);
        Serial.println(Setpoint:  );
        Serial.println(Setpoint); 
    }
     
   }
   
   
  //if(i<10)
  myPID.Compute();
  
  while((Input<Setpoint-1 || Input>Setpoint+1) && Output!=0.0)
  {
    Serial.println(Input:  );
    Serial.println(Input);
    
    {
      myPID.Compute();
    
        Serial.println(output: );
        Serial.println(Output);
        
      if(myPID.smer==1) // myPID.smer tell us in what direction motor should turn
        Input+=Output/10; //simulate motor turning and potentiometer new value
        else
         Input-=Output/10;
         
        Serial.println(Input:  );
        Serial.println(Input);
        Serial.println(Direction);
        Serial.println(myPID.smer);
        Serial.println(----------------);
     }
     
  }
  
}

when you read potentiometer value you should MAP it from 0 to 180.
same thing you should do with values that PC sends to Arduino.

Here is my modded library

How i could send data from arduino via x-sim to game???

Hi,
I have problems with how to define the arduino in x sim. I can't see the com of the arduino in the list!!
if anyone can help I will be very happy.

tnx
