uOSC : The Open Sound Control Reference Platform for Embedded Devices

Schmeder, Andrew and Freed, Adrian

Proceedings of the International Conference on New Interfaces for Musical Expression

A general-purpose firmware for a low cost microcontroller is described that employs the Open Sound Control protocol over USB. The firmware is designed with considerations for integration in new musical interfaces and embedded devices. Features of note include stateless design, efficient floating-point support, temporally correct data handling, and protocol completeness. A timing performance analysis is conducted.
