Toby Harris / OSC

An Open Sound Control library for the mbed, created to be compatible with Recotana's OSCClass library (http://recotana.com) for the Arduino with Ethernet shield. It also uses parts of the OSC Transceiver(Sender/Receiver) code by xshige written by: Alvaro Cassinelli, October 2011 tweaked by: Toby Harris / *spark audio-visual, March 2012

Dependents:   SPK-DVIMXR
