Arduino OSC Processing

[mu234]

Hello all!

I have started with transferring the data from Arduino to the Processing, actually to draw, internally on mac.

I have started with the examples, however, I cannot get the basic stuff working.

For example, I am using the OSC/README.md at master · CNMAT/OSC · GitHub
Arduino library, and the oscP5 for processing.

Started with a simple send/receive the msg. For example, I want to send the msg from the Arduino -> Processing, wondering, why does this not do anything?

Arduino code:

/*
    Make an OSC message and send it over UDP
    
    Adrian Freed
 */
#include <SPI.h>    
#include <Ethernet.h>
#include <EthernetUdp.h>
#include <OSCMessage.h>

EthernetUDP Udp;

//the Arduino's IP
IPAddress ip(128, 32, 122, 252);
//destination IP
IPAddress outIp(128, 32, 122, 125);
const unsigned int outPort = 9999;

 byte mac[] = {  
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // you can find this written on the board of some Arduino Ethernets or shields

void setup() {
  Serial.begin(115200);
  
  Ethernet.begin(mac,ip);
    Udp.begin(8888);

    

}


void loop(){
  //the message wants an OSC address as first argument
  OSCMessage msg("/analog/0");
  //msg.add((intOSC_t)analogRead(0));

  int randNumber = random(1, 20);
  
  msg.add((intOSC_t)randNumber);
  
  Udp.beginPacket(outIp, outPort);
    msg.send(Udp); // send the bytes to the SLIP stream
  Udp.endPacket(); // mark the end of the OSC Packet
  msg.empty(); // free space occupied by message

  delay(20);
}

Processing code:

/*
Receives and visualizes OSCBundles sent over UDP

Use with /examples/UDPSendMessage

or with /examples/SerialSendMessage in conjunction 
with /Applications/Processing/SLIPSerialToUDP
*/

import oscP5.*;
import netP5.*;
  
OscP5 oscP5;

void setup() {
  size(150,300);
  frameRate(30);
  //set this to the receiving port
  oscP5 = new OscP5(this,9001);
}


void draw() {
  background(0); 
  //draw the analog values
  float analog0Height = map(analogValue0, 0, 1024, 0, 200);
  fill(255);
  rect(50, 250, 50, -analog0Height);
  //and the labels
  textSize(12);
  text("/analog/0", 50, 270);
}

int analogValue0 = 50;

// incoming osc message are forwarded to the oscEvent method. 
void oscEvent(OscMessage theOscMessage) {
  //println(theOscMessage.addrPattern());
  if (theOscMessage.addrPattern().equals("/analog/0")){
    analogValue0 = theOscMessage.get(0).intValue();
  } 
}

Any ideas, comments are more than welcome!

Best.

Hello all,

found the example with the code works just well (https://docs.arduino.cc/built-in-examples/communication/Graph/)

However, this is the example with only one read, but I have two, for instance, in Arduino printout, if the values are separated with a blank, both are nicely drawn, how to do that with processing, for example, I would like to have each channel under control and draw different stuff.

Any ideas?

Best.
