OSC - Open Sound Control

Example code and pd patches are available at github: https://github.com/lxmill/osc-party/

OSC + Pure Data + Raspberry Pi

Setting up Pure Data + OSC on the Raspberry Pi

  apt-get update
  apt-get install puredata
  apt-get install pd-mrpeach pd-mrpeach-net pd-osc

after installing, add extra folders to path:
file > preferences > path > new > /usr/lib/pd/extra and select mrpeach, net and osc folders

Example 1 : Direct messages between two machines

Neste exemplo temos dois raspberrypi ligados à mesma rede.

Cada uma das máquinas envia e recebe mensagens de osc através de udpsend e udpreceive, criadas pelos objetos osc da biblioteca pd-osc.

In this example we have two raspberries connected to the same netweork

Each one receives OSC messages via udpsend and udpreceive, provided by the osc objects of the pd-osc library.

Example 2 : Talking through a server

Dois raspberrypi ligados a um servidor através da mesma rede.

Cada uma das máquinas envia e recebe mensagens de osc através de udpsend e udpreceive através do servidor-

No servidor é feita a ligação directa entre udpreceive e udpsend podendo escolher o routing de ligação entre os pi.

Two raspberries connected to each other via a central server.

Each of the machines receive OSC messages via udpsend and udpreceive via the server.

On the server the connections between udpreceive and udpsend are used to route messages between the the two pi's

Example 3 : Talking through a server and choosing destinations

Dois raspberrypi ligados a um servidor através da mesma rede.

Cada uma das máquinas envia e recebe mensagens de osc através de udpsend e udpreceive através do servidor-

Cada um dos pis define para onde que máquina quer enviar mensagem e o servidor faz esse routing com routeOSC, primeira ramo da árvore osc.

Two raspberries connected to each other via a central server.

Each of the machines receive OSC messages via udpsend and udpreceive via the server.

In this case each the patch running on each pi can address the messages and the server will route them automatically using routeOSC, using the first parameter of the osc message path.

OSC + Pure Data + Arduino

Example 1 : Sending/receiving via ethernet

In this example the we can control the state of an LED on the arduino via pure data, and receive values from the LDR light sensor.

OSC messages are sent from the arduino using the OSC for Arduino library, and using the EthernetUDP object from the Ethernet library.

In this case, the arduino will send osc messages to the source of the messages it receives, using udp.remoteIP(). When the sketch starts, the arduino will not have a destination for the stream of ldr readings until it receives a message.

We also tested this with the Adafruit Feather M0 Adalogger + Ethernet Wing.

Example 2 : Sending/receiving via wifi with esp8266

This example is the same, except communication is over wifi using the Adafruit Feather ESP8266. This time we are also sending messages from the Feather to a defined IP, set with the remote_ip variable.
