OSC Packages Dropped

in Contributed Library Questions • 5 months ago

Hi all.

So I am having a REALLY weird problem. I send information from Processing (1.5) with the oscP5 library, to Arduino (1.0) - using the Z_OSC library. However, a few packages are lost - truncated data!!!!

But it is weird because if I send the same information from MaxMSP, packages go to the Arduino.

And also, if I send from Processing to MaxMSP, the packages are received just fine!!!

If anyone has a clue of what may be the problem, you know what to do...

Cheers

well…without any code, it's difficult to help you…
you should post the part of the code which let us understand what you try to achieve (what kind of informations, and how you transmit them…).

Of course code examples are always much more helpful. I just thought maybe it was something more obvious. Anyhow, here is the code for Processing and Arduino.

I use latest Processing, oscP5, and controlP5 libraries, Arduino 1.0, latest Z_OSC, and you might have to use the Ethernet shield - as I send the OSC data through there.

The code works just fine, however most of the times values do not match.

Processing:

//Processing sketch
import controlP5.*;
import oscP5.*;
import netP5.*;
ControlP5 cp5;
OscP5 oscP5;
NetAddress myBroadcastLocation;
//Values used for data interpolation
float interpValue, percentage, finalValue;
int slider, counterTime, counter;
int storedValue, newValue = 0;
void setup() {
size(640, 250);
noStroke();
frameRate(30);
cp5 = new ControlP5(this);
cp5.addSlider("slider").setPosition(20, 100).setSize(150, 20).setRange(0, 255).setValue(255);
oscP5 = new OscP5(this, 7400);
myBroadcastLocation = new NetAddress("141.163.187.151", 10000);
}
void draw() {
background(80);
interpolateValues();
sendOSC();
}
void slider (int theSlider) {
newValue = theSlider;
}
void interpolateValues() {
if (storedValue != newValue) counterTime = 100;
if (counterTime != 0) counter++;
if (counter > counterTime) counter = counterTime;
percentage = map (counter, 0, 100, 0., 1.);
interpValue = lerp (storedValue, newValue, percentage);
if (percentage == 1) storedValue = newValue;
counterTime = 0;
}
void sendOSC() {
OscMessage sendValue = new OscMessage("/value/");
if (finalValue != interpValue) {
sendValue.add(finalValue);
oscP5.send(sendValue, myBroadcastLocation);
finalValue = interpValue;
println("finalValue: " + finalValue);
}
}

Arduino:

//Arduino Code
#include <SPI.h>
#include <Ethernet.h>
#include <Z_OSC.h>
float red1 = 0;
// Put your Ethernet Mac Address
byte myMac[] = {
0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
// Put your IP address
byte myIp[] = {
111,111,111,111 };
int serverPort = 10000;
Z_OSCServer server;
Z_OSCMessage *rcvMes;
void setup(){
Serial.begin(19200);
Ethernet.begin(myMac ,myIp);
server.sockOpen(serverPort);
}
void loop(){
if(server.available())
{
rcvMes=server.getMessage();
logMessage();
}
}
void logMessage()
{
uint16_t i;
byte *ip = rcvMes->getIpAddress();
float floatValue;
float rcvRed1;
char *stringValue;
int rcvMode;
for(i=0 ; i<rcvMes->getArgsNum(); i++)
{
switch( rcvMes->getTypeTag(i) )
{
case 'f':
floatValue = rcvMes->getFloat(i);
String red1msg = "/value/";
if (red1msg==rcvMes->getZ_OSCAddress())
{
rcvRed1 = rcvMes->getFloat(0);
Serial.print("red1: ");
Serial.println(rcvRed1);
red1 = rcvRed1;
}
break;
}
}
}

could you post the max patch ? or Pd patch ? (I can't test with arduino)

As I described in the first post, the Processing sketch works fine with the Max patch (or any other Processing sketch). The problem is between Processing and Arduino, although Max + Arduino communicate just fine.

even if it works, it could have been some problems…
that would have been a way to see what is going on (especially everybody doesn't have arduino board…).
this a first step to debug, see why it works. (between processing and max/msp…). have you try sending data without interpolation values ? I think it would be more efficient to do this into arduino, if I understood your code correctly…).
