Flock Radio Messaging System

"Flock and Peep protocols for Arduino-style MCUs.

Flock is a non-hierarchical, self-negotiating radio messaging protocol. Flock (and Peep) protocols are entirely timer-based. It is designed to carry message payloads, which consist of keyword::number pairs, with a heavy emphasis event signaling.

The code is contained in a single (library) object that contains the Flock/Peep protocol logic, which in turn loads the NRF24L01+ driver module. This code requires an event-loop style coding scheme. All of the code is non-blocking. It's fairly lightweight, and runs fine on an Uno (Atmega328)."
