替代MICRF610 |

1 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. 3 Glossary ADC Analogue to DIGITAL Converter eCOG1 Cyan TECHNOLOGY target MICRO CONTROLler LCD Liquid CRYSTAL DISPLAY RSSI Receive Signal Strength Indicator UART Universal Asynchronous Receiver/Transmitter RF Radio Frequency FSK Frequency Shift Keying PLL Phase LOCKed Loop Persistent PORT / Refers to connections made on PORTs in the range 0 to 7 that are persistent.
