This is an OSC library for the mbed, created to be compatible with Recotana\'s OSCClass library (http://recotana.com) for the Arduino with Ethernet shield. I have also used parts of the OSC Transceiver(Sender/Receiver) code by xshige. It has many limitations, but it works for simple things (check comments on the mbedOSC.h). It will be evolving. written by: Alvaro Cassinelli, 7.10.2011
