Introduction
This application note describes an implementation of the MicrelNet RF network
topology on Cyan Technology’s eCOG1 micro-controller. It describes the
interfacing with the MICRF610 transceiver, offering frequency shift keying
modulation in the 868-870 MHz band using two channels.
2 Features
• Lock detect and receive signal strength (RSSI) indicator
• Complete radio board design schematic for plug-in integration with the
eCOG1 development board.
• LED display for transmit and receive (on development board).
• Manchester encoded data transfer to avoid bias and aid clock recovery.
• Use of internal eCOG1 information block (non-volatile) memory for
storage of network address; reduces system costs.
• Interrupt driven design provides maximum flexibility and portability.
• Persistent and non-persistent network port connections
• Additional user level and transport protocols for inter-node
communications.
• Application binding to ports supports user function calls in response to
port activity (receive and transmit).
• Remote control of connections and services running on networked
nodes.
• Example software: remote UART and remote LCD control.
• Data retransmission and packet forwarding for maximum flexibility and
robustness.
