1. Lab1: LED Control ZigbeX mote has Red, Yellow, Green LED. This lab using LED control component provided by TinyOS exercises LED device control.

2. ZigbeX LED

3. LED in ZigbeX • Use of LED • In order to check whether certain device’s operation is performed successfully or not. • LedsC Component • LedsC is component to control the LED device.

4. Leds functions

5. LED sample progam

6. Blink program • Blink program • An instant component named “Blink”. Forconfiguration andmodule,two files Blink.nc &BlinkM.nc are required. • Blink.nc is for configuration which uses many other componentsused in Blink program • BlinkM.nc is a implemented module for Blink program. • Directory of Blink program • c:\Programfiles\UCB\cygwin\opt\tinyos‐1.x\contrib\zigbex\Blink\ • Bink.nc &BlinkM.nc

7. Blink.nc • Blink.nc . • Main, LedSc, BlinkM are used and shows how they are wired. configuration Blink { } implementation { components Main, BlinkM, LedsC; Main.StdControl ‐> BlinkM.StdControl; BlinkM.Leds ‐> LedsC; }

8. BlinkM.nc • BlinkM.nc (1) module BlinkM { provides { interface StdControl; } uses { interface Leds; } } implementation { task void led_task(); command result_t StdControl.init() { call Leds.init(); return SUCCESS; } • - declared by “provide” interfaceand • “uses” interface • In implementation block is for user programming • task (function w/o parameter) : declaration • StdControlinit(), start(), stop() sequence. • - StdControl.init() calls Leds.init() • to initialize LedsC.

9. BlinkM.nc • BlinkM.nc (2) command result_t StdControl.start() { post led_task(); return SUCCESS; } command result_t StdControl.stop() { return SUCCESS; } task void led_task() { int i; for(i=0; i<10; i++) { call Leds.yellowOn(); TOSH_uwait(30000); call Leds.greenToggle(); } } } • After StdControl.init(), StdControl.start() is • executed automatically • In StdControl.start(), defined by “task” • led_task() is called by “post” header. • - No specific implemetation in StdControl.stop(). • - Here your algorithm to control LED

10. LED Lab Item: host PC(labtop), 1 mote , ISP(AVR), cable

11. LED lab -1 • Start cygwin • Goto target directory • Compile - make zigbex cd /opt/tinyos‐1.x/contrib/zigbex cd Blink

12. LED lab -2 • Download binary code to ZigbeX using ISP tool • After compile, folder, build/zigbex is created and main.hex is the binary. • Run AVR studio

13. Lab -3 • Run AVR Studio4 • Select ‘cancel’

14. Lab -4 • Select • Tool  Program AVRAuto Connect

15. Lab -5 • Find ‘main.hex’ file

16. Lab - 6 • Select ‘Program’

17. Lab - 5 • Check the message and graph

18. LED lab result • Output • Yellow LEDis con, every 30msGreen LEDis toggling • Please change source code to test RED.
