Bi-directional low power RF Remote Control application boards

These simple application boards use firmware based on the BD118 remote control systems to implement a bi-directional control link. A system consists of a master board (which initiates communication burst cycles) and a slave (which responds to them). In hardware terms these boards are the same, but have different firmware loaded.
