OSC Example

Here’s the example I shared in class for using OSC with the Photons. It’s also available as a Gist on Github.

#include "simple-OSC/simple-OSC.h"

// create OSC object
UDP osc;

// set IP addresses and ports for I/O
IPAddress outIp(128, 237, 246, 8);
unsigned int outPort = 9000;
unsigned int inPort = 3000;

// creat named variables for pins
int leftMotorPin = D1;
int rightMotorPin = D0;

int ledPin = D7;


// runs once at the beginning of the program
void setup() {

	// start serial &amp; OSC
	Serial.begin(115200);
	osc.begin(inPort);

	pinMode(leftMotorPin, OUTPUT);
	pinMode(rightMotorPin, OUTPUT);
	pinMode(ledPin, OUTPUT);

	// You can view Serial.print() commands sent from the Photon via your computer's console (while it's plugged in to the computer).
	// Do `ls /dev/tty.usb*` in terminal to find the address of the Photon,
	// then do `screen ADDRESS BAUD` to make a serial monitor.
	// For example, if my Photon is "/dev/tty.usbmodem331", I'd do 'screen /dev/tty.usbmodem331 115200'.
	
	// while waiting for connection to be set up
	while (!WiFi.ready()) {
		// wait and print to console
		delay(500);
		Serial.print(".");
	}
	// print to console when connection is started
	Serial.println("");
	Serial.println("WiFi connected");
	// get Photon's IP:PORT and print it to console
	IPAddress ip = WiFi.localIP();
	Serial.print(F("ip : ")); 
	Serial.print(ip);
	Serial.print(F(" : ")); 
	Serial.println(inPort);
}


// continuously runs throughout the life of the program, after setup()
void loop() {
	

	// RECEIVE ===

	// create message object
	OSCMessage inMessage;

	// if the incoming OSC packet is larger than 0 bytes
	int size = 0;
	size = osc.parsePacket();
	if (size &gt; 0) {
		
		// copy each byte from the incoming packet to the message object
		while (size &gt; 0) {
			inMessage.fill(osc.read());
			size--;
		}
		
		// if the message can be parsed
		if (inMessage.parse()) {
				
				Serial.println("Message Received");

			// route it to a callback function
			inMessage.route("/A", leftCallback);
			inMessage.route("/B", rightCallback);
		}
	}
	

	// SEND ===

	// To test sending messages, you can use `nc -ul PORT` in terminal to listen to incoming messages on localhost.
	// For example, if outIp is my computer's IP address (128.237.246.8), and outPort is the port I'm sending to (9000),
	// then I'd run `nc -ul 9000` in terminal, and send a message from the Photon using the following example.
	//
	// For TouchOSC, you'd want to send the appropriate route to your mobile device's IP. Follow instructions [here](http://hexler.net/docs/touchosc)

	// create an outgoing message object
	OSCMessage outMessage("/sensor");

	// add parameters to the object
	outMessage.addString("test");
	outMessage.addFloat(-3.14);
	outMessage.addInt(-1);

	// send the object
	outMessage.send(osc, outIp, outPort);
}


// callbacks are run asynchronously from the main loop()
void leftCallback(OSCMessage &amp;inMessage) {
		Serial.println("LEFT CALLBACK");
		
		if (inMessage.getInt(0) == 0) {
			Serial.println("LEFT OFF");
			digitalWrite(leftMotorPin, LOW);
			digitalWrite(ledPin, LOW);
		} else {
			Serial.println("LEFT ON");
			digitalWrite(leftMotorPin, HIGH);
			digitalWrite(ledPin, HIGH);
		}

}

void rightCallback(OSCMessage &amp;inMessage) {
		Serial.println("RIGHT CALLBACK");
		Serial.println(inMessage.getInt(0));

		if (inMessage.getInt(0) == 0) {
			Serial.println("RIGHT OFF");
			digitalWrite(rightMotorPin, LOW);
			digitalWrite(ledPin, LOW);
		} else {
			Serial.println("RIGHT ON");
			digitalWrite(rightMotorPin, HIGH);
			digitalWrite(ledPin, HIGH);
		}

}
