Micropython-osc (aka uosc) is a minimal Open Sound Control (OSC) client and server library for MicroPython and CPython 2 or 3.

It should work on the Unix, stmhal (Pyboard) and esp8266 port of MicroPython and under CPython 2.7 and 3.3+. Since OSC is a network-protocol using UDP or TCP as a transport, the main requirement is a working and compatible socket module. Currently this module only supports UDP as the transport.

The server code so far has only been tested under the Unix port and CPython 2 and 3, but the client portion has been confirmed to work on a ESP-8266 board running MicroPython 1.8.x.

Here's a minmal usage example for the client. Further documentation is currently only available by looking at the docstrings and the source code (the whole package has a total LLOC of < 400).

from uosc.client import Bundle, Client, create_message

osc = Client('192.168.4.2', 9001)
osc.send('/controls/frobnicator', 42, 3.1419, "spamm")
b = Bundle()
b.add(create_message("/foo", bar))
b.add(create_message("/spamm", 12345))
osc.send(b)
