  1. TinyOS Wireless and Mobile Networking Lab. Konkuk University

  2. Outline • Installation • Software Architecture • NesC Programming • Example codes • Blink • Moss • SimpleRf

  3. Installation • TinyOS install

  4. Installation (con't) • Cygwin install • Cygwin setup

  5. Installation (con't) • RPM upgrade • rpm -Uvh tinyos-1.1.13May2005cvs-1.cygwin.noarch.rpm

  6. Installation (con't) • msp-gcc install delete

  7. Installation (con't) • msp-gcc path setup • export PATH=$PATH:/cygdrive/c/mspgcc/bin

  8. Installation (con't) • overwriting some files

  9. Software Architecture TinyOS Application Component Main Command Handler Event Handler Counter Clock INT_TO_LED Task LED Tiny Scheduler

  10. Software Architecture (con't) • Relationship of Commands, Tasks, Events and two-level scheduler Higher Level Component • Both event and command can schedule tasks • Commands can not signal events • Tasks preemptive by events • Tasks non preemptive by tasks Signal Events Command Lower Level Component Task Task Task

  11. NesC Programming • Wiring Module Configuration Provide Wiring Interface Use Implement Module

  12. NesC Programming (con't) Module Configuration Provided components Used components • Wiring with interfaces • Declare interfaces using and providing • Implement commands and events

  13. NesC Programming (con't) • Blink module BlinkM { provides { interface StdControl; } uses { interface Timer; interface Leds; } } implementation { uint8_t i; command result_t StdControl.init() { call Leds.init(); return SUCCESS; } command result_t StdControl.start() { return call Timer.start(TIMER_REPEAT, 500); } command result_t StdControl.stop() { return call Timer.stop(); } event result_t Timer.fired() { i++; if(i%3 == 1) call Leds.blueToggle(); else if(i%3 == 2) call Leds.redToggle(); else if(i%3 == 0) call Leds.yellowToggle(); return SUCCESS; } }

  14. NesC Programming (con't) • Blink (con’t) configuration Blink { } implementation { components Main, BlinkM, SingleTimer, LedsC; Main.StdControl -> SingleTimer.StdControl; Main.StdControl -> BlinkM.StdControl; BlinkM.Timer -> SingleTimer.Timer; BlinkM.Leds -> LedsC; }

  15. NesC Programming (con't) • Moss #define MORSE_WPM 12 #define MORSE_UNIT (1200/MORSE_WPM) module MossM { provides { interface StdControl; } uses { interface Timer; interface Leds; interface HPLUART as UART; } } implementation { command result_t StdControl.init() { call UART.init(); call Leds.init(); call Leds.redOff(); call Leds.yellowOff(); call Leds.greenOff(); return SUCCESS; } command result_t StdControl.start() { return call Timer.start(TIMER_REPEAT, 1000); } command result_t StdControl.stop() { return call Timer.stop(); } event result_t Timer.fired() { static char *morse = "... .-.. .-.. -- "; static char *current; if(!current) current = morse;

  16. NesC Programming (con't) • Moss (con’t) switch(*current) { case ' ': if(!call Leds.get()) { call Leds.yellowOn(); call Timer.start(TIMER_ONE_SHOT, 2*MORSE_UNIT); call UART.put(' '); } else { call Leds.yellowOff(); call Timer.start(TIMER_ONE_SHOT, 2*MORSE_UNIT); current++; } break; case '.': if(!call Leds.get()) { call Leds.redOn(); call Timer.start(TIMER_ONE_SHOT, MORSE_UNIT); call UART.put('.'); } else { call Leds.redOff(); call Timer.start(TIMER_ONE_SHOT, MORSE_UNIT); current++; } break; case '-': if(!call Leds.get()) { call Leds.greenOn(); call Timer.start(TIMER_ONE_SHOT, 3*MORSE_UNIT); call UART.put('-'); } else { ..

  17. NesC Programming (con't) • SimpleRf configuration SimpleRf {} implementation { components Main, SimpleRfM, CC2420RadioC, CC2420ControlM, TimerC, LedsC; Main.StdControl -> TimerC.StdControl; Main.StdControl -> SimpleRfM.StdControl; SimpleRfM.Timer -> TimerC.Timer[unique("Timer")]; SimpleRfM.Leds -> LedsC; SimpleRfM.CC2420Control -> CC2420ControlM; SimpleRfM.RadioControl -> CC2420RadioC; SimpleRfM.RadioSend -> CC2420RadioC.Send; SimpleRfM.RadioReceive -> CC2420RadioC.Receive; }

  18. NesC Programming (con't) • SimpleRf (con’t) module SimpleRfM { provides { interface StdControl; } uses { interface Leds; interface Timer; interface CC2420Control; interface StdControl as RadioControl; interface BareSendMsg as RadioSend; interface ReceiveMsg as RadioReceive; } } implementation { TOS_MsgPtr pData; TOS_Msg Data; uint8_t count = 0; task void sendDATA() { pData->addr = 0x0001; pData->length = 1; pData->data[0] = count; count++; call Leds.yellowToggle(); call RadioSend.send(pData); }

  19. NesC Programming (con't) • SimpleRf (con’t) command result_t StdControl.init() { pData = &Data; call Leds.init(); call RadioControl.init(); return TRUE; } command result_t StdControl.start() { // Set CC2420 channel // Valid channel values are 11 through 26. call CC2420Control.TunePreset(11); call RadioControl.start(); if(TOS_LOCAL_ADDRESS == 0x0000) call Timer.start(TIMER_REPEAT, 1024); return TRUE; } command result_t StdControl.stop() { call RadioControl.stop(); call Timer.stop(); return TRUE; } event result_t Timer.fired() { post sendDATA(); return SUCCESS; }

  20. NesC Programming (con't) • SimpleRf (con’t) event TOS_MsgPtr RadioReceive.receive(TOS_MsgPtr packet) { call Leds.redToggle(); return packet; } event result_t RadioSend.sendDone(TOS_MsgPtr msg, result_t success) { return SUCCESS; } }
