Hello guys.. i am new to processing IDE. I have a code of a basic Radar spotting template. when using Arduino IDE i can see the values coming back from sensor using serial print. But in processing this code is not drawing the objects detected in a range. Please help what changes i have to make. in this code.. i got this code from website..
import processing.serial.*;
Serial port;
Serial port2;
String data = "";
String Radius = "";
String Theta = "";
int index = 0;
float distance = 0;
float angle = 0;
float pi = 22.0/7;
void setup()
{
size(1000,1000);
background(255,255,255);
ellipse(500,500,1000,1000);
line(500,0,500,1000);
line(0,500,1000,500);
line(500,500,1000,0);
line(500,500,0,0);
port = new Serial(this, "COM3", 9600);
port.bufferUntil('.');
}
void draw()
{
}
void serialEvent(Serial port)
{
data = port.readStringUntil('.');
data = data.substring(0, data.length() - 1);
index = data.indexOf(",");
Radius = data.substring(0, index);
Theta = data.substring (index+1 , data.length());
translate(500,500);
point (0,0);
distance = float(Radius);
angle = float(Theta) /180 * pi;
fill(30,200,30);
ellipse(distance * cos(angle) , -1 * distance * sin(angle) , 5,5);
}
Any suggestions is worth a gold... Thank you
