INTRODUCTION
The FRPC2 is a self-contained plug-on radio port which requires only a simple
antenna, 5V supply and a byte-wide I/O port on a host microcontroller (or
bi-directional PC port). The module provides all the RF circuits and processor
intensive low level packet formatting and packet recovery functions required
to interconnect an number of microcontrollers in a radio network.
A data packet of 1 to 60 bytes downloaded by a Host microcontroller into
the FRPC2's packet buffer is transmitted by the FRPC2's transceiver and
will "appear" in the receive buffer of all the FRPC2's within radio range.
A data packet received by the FRPC2's transceiver is decoded, stored in
a packet buffer and the Host microcontroller signaled that a valid packet
is waiting to be uploaded.
