Reading MPU6050 from Processing

Processing for Pi

This reference may or may not be helpful; it contains a Processing sketch. We can help with basic code to connect to serial but there is quite a bit of data being sent from one of these gyros: https://github.com/TKJElectronics/Example-Sketch-for-IMU-including-Kalman-filter/blob/master/Graph/Graph.pde

Basic Serial Code for Processing:

import processing.serial.*;

Serial myPort;    // The serial port
String inStr;    // Input string from serial port
int lf = 10;    // ASCII linefeed
float x, y, z;

void setup() {
  surface.setVisible(false); // Output is in console at bottom of editor
  // List all the available serial ports:
  printArray(Serial.list());
  // Enter device number for your system
  myPort = new Serial(this, Serial.list()[4], 9600);
  myPort.bufferUntil(lf);
}

void draw() {
}

void serialEvent( Serial myPort) {
  //'\n' (line feed) is delimiter indicating end of packet
  inStr = myPort.readStringUntil('\n');
  //make sure our data isn't empty before continuing
  if (inStr != null) {
    //trim whitespace and formatting characters (like carriage return and/or line feed)
    inStr = trim(inStr);  //Data is sent as a string
    println("inStr = ", inStr);    
    String[] myData = split(inStr, ','); // String is split into array at comma
    //printArray(myData);   
    x = Float.valueOf(myData[0]); // Array elements are converted back to integers
    println("x = ", x);
    y = Float.valueOf(myData[1]);
    println("y = ", y);
    z = Float.valueOf(myData[2]);
    println("z = ", z);    
  }
}

Arduino code for testing purposes:

int randNumber[3];

void setup() {
  Serial.begin(9600);
}

void loop() {
  // print a random number from 0 to 299
  randNumber[0] = random(300);
  Serial.print(randNumber[0]);
  Serial.print(','); // Comma separated values
  // print a random number from 10 to 19
  randNumber[1] = random(10, 20);
  Serial.print(randNumber[1]); 
  Serial.print(',');
  // print a random number from 500 to 899
  randNumber[2] = random(500,900);
  Serial.println(randNumber[2]);// line feed terminated
  delay(50);
}
