Unclear examples for beginners

[Somnitec]

The examples are written in a way which is not easily scalable for beginners. I spend considerable time figuring out how to make this library work for me and to avoid this hassle for others, please consider adding a basic send and receive example similar to mine pasted below.

#include <OSCBundle.h>
#include <SLIPEncodedSerial.h>
SLIPEncodedSerial SLIPSerial(Serial);

int testValue = 1337;

//basic timer
unsigned long timer = 0;             // will store last time  updated
unsigned long timerInterval = 1000;  // interval at which to time (milliseconds)

void setup() {
  SLIPSerial.begin(115200);
  pinMode(13, OUTPUT);

}

void loop() {
  //check for new messages as fast as possible
  receiveOSC();

//echo the value every timerInterval
  unsigned long currentMillis = millis();
  if (currentMillis - timer > timerInterval) {
    timer = currentMillis;
    sendOSC();
  }

}

void receiveOSC() {
  OSCMessage messageIN;
  int size;
  //receive a bundle
  if (SLIPSerial.available()) {
    while (!SLIPSerial.endofPacket())
      if ( (size = SLIPSerial.available()) > 0)
      {
        while (size--)
          messageIN.fill(SLIPSerial.read());
      }
    if (!messageIN.hasError())
    {
      messageIN.dispatch("/test/in", action);
    }
  }
}

void action(OSCMessage &msgIn) {
  int testValue = msgIn.getInt(0);
}

void sendOSC() {
  OSCMessage msg("/test/out");
  msg.add(testValue);
  SLIPSerial.beginPacket();
  msg.send(SLIPSerial); // send the bytes to the SLIP stream
  SLIPSerial.endPacket(); // mark the end of the OSC Packet
  msg.empty(); // free space occupied by message
}

I completely agree. I have been trying for the past 6 hours and have not been able to send a message to or from at all yet.

I am trying to do it over Ethernet - which is only more mysterious...

Might you have a simple send example for that?

What device are you trying to send OSC messages to ? I've been using TouchOSC to control Teensy boards and wrote a little beginner tutorial. Not sure if it helps. http://trippylighting.com/teensy-arduino-ect/touchosc-and-arduino-oscuino/

I am trying to send OSC messages to my Mac BookPro. Preferably to Processing although Quartz Composer works fine.

I see a lot of examples using TouchOSC. But I am trying to strip away the layers of complexity and make it as dead simple as possible. I just cannot seem to understand what I am missing. I thought this would be a piece of cake!

Here is the thread on the Arduino Forums.

+1 for some simple examples. I would also in the readme describe the difference between a osc message and bundle. There is as far as I can see no included code example that actually shows how to receive a message. All the arduino code examples deal with receiving bundles only.

I wanted to control my arduino clone (adafruit feather m0 wifi) using the i-score osc sequencer that sends osc messages not bundles, and based on the examples could only make it work by using a max msp translation patch to encode the messages comming from i-score to bundles and send from max to the arduino(Wifi).

Only much later and after much googling did I think "surely it must be possible to receive a osc message" and start emplying my limited coding experience to decode the API.

It wass of course possible, Please make the difference between a bundle and message clear for those checking out the library for the first time!!

How easy is it to code something that uses say 6/8 inputs from buttons, on a Leonardo Ethernet board. I want to build a device that has some buttons that each send a different OSC command out from each button on ethernet.

This example does not work for me, has anyone else tried it? Thank you for the simple example that uses 'Serial' in SLIPSerial instead of 'Serial1' as I have an uno not a mega or leonardo. I am fairly confident that I am sending OSC to my arduino (though I haven't worked out how to test it yet) but I don't think my arduino is sending back yet and just don't know how to troubleshoot this sort of problem. Has anyone else had any progress?
