i m trying to send an osc message from my of application to an ethernet arduino. I am able to receive input but i am not able to read out any values: i m wondering if you can help me:
of in header
#define HOST "192.168.178.130" //arduino ip
#define RPORT 12000 //incoming
#define SPORT 10000 //outgoing
#define NUM_MSG_STRINGS 100
in cpp
cout << "listening for osc messages on port " << RPORT << "\n";
receiver.setup(RPORT); //set up receiver
sender.setup(HOST, SPORT); //set up sender
of sending function
void oscc::sendMessages(){
ofxOscMessage m;
m.setAddress("/Eth_ArdOSC/toggle2");
m.addFloatArg(3.0);
sender.sendMessage(m);
}
the arduino code
#include <SPI.h>
#include <Ethernet.h>
#include <ArdOSC.h>
OSCServer server;
OSCClient client;
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
int serverPort=10000; //OF incoming port
int destPort=12000; //OF outcoming port
float wert;
int flag=0;
void setup(){
Serial.begin(115200);
Serial.println("DNS and DHCP-based OSC server");
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
while(true);
}
// print your local IP address:
Serial.print("Arduino IP address: ");
for (byte thisByte = 0; thisByte < 4; thisByte++) {
// print the value of each byte of the IP address:
Serial.print(Ethernet.localIP()[thisByte], DEC);
Serial.print(".");
}
Serial.println();
Serial.println();
//start the OSCserver
server.begin(serverPort);
//add OSC callback function. One function is needed for every TouchOSC interface element that is to send/receive OSC commands.
server.addCallback("/Eth_ArdOSC/toggle2", &funcOnOff);
}
void loop(){
if(server.aviableCheck()>0){
Serial.println("alive! ");
Serial.println(wert);
}
}
void funcOnOff(OSCMessage *_mes){
float value = _mes->getArgFloat(0);
//create new osc message
wert=value;
OSCMessage newMes;
//set destination ip address & port no
newMes.setAddress(_mes->getIpAddress(),destPort);
newMes.beginMessage("/Eth_ArdOSC/toggle1");
newMes.addArgFloat(value);
client.send(&newMes);
}
the serial board output (when starting the sending osc function in of by pressing a key):
?óDNS and DHCP-based OSC server
Arduino IP address: 192.168.178.130.

Which arduino osc library are you using? If your using ardOSC, it doesn’t accept OSC bundles- only simple messages. But this can be easily fixed from the OF side. There’s a thread here which worked for me-http://forum.openframeworks.cc/t/osc-from-of-to-arduino/6563/0
well i’m running into some problems when i send more than 2 messages from open frameworks, could this have something to do with the bundle thing.
void oscc::sendMessages(){
ofxOscMessage m;
m.setAddress("/head/visual");
m.addIntArg(r); //first value
m.addIntArg(g); //second value
m.addIntArg(b); //third value
m.addIntArg(b); //test value
sender.sendMessage(m);
i receive the values at the arduino, pass them to red, green, blue etc. and send them back TO OF:
red = _mes->getArgInt32(0);
green = _mes->getArgInt32(1);
blue =_mes->getArgInt32(2);
val = _mes->getArgInt32(3); //test value
//pass roll, pitch, yaw to variable for sending, as Degrees
oscRoll=ToDeg(roll);
oscPitch=ToDeg(pitch);
oscYaw=ToDeg(yaw);
OSCMessage newMes; //create new osc message
//set destination ip address & port no
newMes.setAddress(_mes->getIpAddress(),destPort);
newMes.beginMessage("/head/direction");
newMes.addArgFloat(oscRoll);
newMes.addArgFloat(oscPitch);
newMes.addArgFloat(oscYaw);
newMes.addArgInt32(red);
newMes.addArgInt32(green);
newMes.addArgInt32(blue);
newMes.addArgInt32(val);
//send osc message
server.stop(); //stop server while sending
client.send(&newMes);
server.begin(serverPort); //start server
if(m.getAddress() == "/head/direction"){
roll= m.getArgAsFloat(0); //get first value
pitch= m.getArgAsFloat(1); //get second value
yawDeg= m.getArgAsFloat(2); //get third value
yawDeg=yawDeg+180; //360 degrees for opengl
r_r=m.getArgAsInt32(3);
g_r=m.getArgAsInt32(4);
b_r=m.getArgAsInt32(5);
test=m.getArgAsInt32(6);
}
b_r has the blue values but switches back to 69 all the time
test is some random number around 1204. The values are ok when i send them.
i did some further testing and it really has to do with the third (2) message i am sending from open frameworks, perhaps ardosc can’t handle more than 2 messages with the work around i was pointed to earlier. Since i am on a short deadline any help will be much appreciated. do you know some easy way to get the two color values into one message, that i can decode in the arduino? thanks, nixon
