While most OSC libraries available thend to embed and assume the use of network transport (UDP), few of them can easily be used with other means of transport, such as USB.
Kian aims to provide a bring-your-own-transport approach to OSC messaging.
The SLIP protocol (RFC 1055) is a very simple encoding system that allows to encapsulate the OSC messages and bundles into entities of information simlare to UDP datagrams, which can then be send to the transport stack and received on the other end.
Kian is :
-
completely transport agnostic, works on local buffers (no logic for network, or serial, etc .. it is up to you)
-
written in portable C89
-
only 3 header files
-
througly internally documented
-
tested
