Platform Details (Hardware) • Micro-Controller (MSP430) • Radio (CC2420) • Flash (STM25P80) • RS232 Trans-receiver (MAX3380) • 16MHz crystal for radio • LEDs • LCD interface (useful for debugging) • JTAG (to download the program) • ADC Lines (to attach sensors)
Motivation • Number of motes available. • Not easily available and expensive for research and teaching purpose in India. • Goal: • To build knowledge base in sensor mote. • Aid easy availability in India. • Develop India specific applications. • To design a low cost, low power platform
Project Details • To test the peripherals attached with the board like :- • Radio • Serial • External Flash • ADC (Sensors connectivity) • LCD interface
Agenda • Software Support • Experiments performed • Demo • Conclusion • Future work
Software support • Independent Programs (IAR workbench) • Use some existing OS • Tiny OS • SOS • Preferred approach • Use Tiny OS • Supports its close counterpart (Tmote) • Easy configurability • Good Documentation
Tiny OS • Open source • Event driven architecture • Uses Components, Interfaces and wiring concept • Small memory footprint • Efficient in power and computation • Supports diverse application design
Radio Component Send and Receive Packet Example
Radio Component Serial Component Send and Receive Packet Example
Radio Component Serial Component Send and Receive Packet Sense Data And send it Either on radio or serial Sensor Example
Experiments Performed • BlinkTORadio • BaseStation (Radio to serial) • Block • BlinkConfig • TestAdc • SenseToSerial • SenseToRadio
Conclusion/Observations • The following peripherals was tested successfully:- • LEDs • Radio • Serial • External Flash • ADC Lines • ADC0 and ADC2 are interchanged
Future Work • LCD interface to be tested • Implement a sensor network protocol on the mote to have a greater confidence

Thank you • Demo • Any Questions??
Difference between kmote and tmote • LCD Interface • Onboard sensor • Transreceiver
Problems Faced • Make the platform work (Linux and windows) • Understanding Tiny OS • Downloading the program • Dump message packets to serial • Attach pot to check ADC
