Testing and Verifiation of Kmote using Tiny OS Manish Aggarwal Guide :- Proff Purushottam K

Kmote board: Front view ADC linesSerial Expansion Line LCD Interface JTAG Power Connector CC2420 Radio User and Reset button LEDs

Kmote board: back view ST flash RS232 Trans-reciever MicroController MSP430 Crystal 16MHz

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

Tiny OS programming

Example Radio Component Send and Receive Packet

Example Radio Component Send and Receive Packet Serial Component

Example Radio Component Send and Receive Packet Serial Component Sense Data And send it Either on radio or serial Sensor

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
