→OSC Messaging
=OSC Messaging=
The bullroarer nodes use Open Sound Control to communicate with the host computer. You can find an introduction to Open Sound Control [http://opensoundcontrol.org/introduction-osc here], and details of the [http://opensoundcontrol.org/spec-1_0 OSC Specification]. The OSC messages are addressed differently to each node. They start with a base address pattern of ''/br/'' followed by the node's number, 1-21. For the examples below I am using the base address for node 1, ''/br/1/''. Control messages from the host computer are sent directly to each node at their IP addresses. Thus, they do not contain any node-specific information in their addressing pattern.
The bullroarer firmware uses the [http://cnmat.berkeley.edu/oscuino OSCuino] library for Arduino and Embedded Processors to do OSC messaging.
