ZigbeX LED



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.



Leds functions functions

Initialization result_t Leds.init() – 3 LED lamp is initialized.

Red LED result_t Leds.redOn() - Red LED On. result_t Leds.redOff() - Red LED OFF. result_t Leds.redToggle() - Red LED toggling

Green LED result_t Leds.greenOn() - Green LED On. result_t Leds.greenOff() - Green LED OFF. result_t Leds.greenToggle() - Green LED toggling.

Yellow LED result_t Leds.yellowOn() - Yellow LED On. result_t Leds.yellowOff() - Yellow LED OFF. result_t Leds.yellowToggle() - Yellow LED toggling.



LED sample progam



Blink program • Blink program

– An instant component named “Blink”. For configuration and module, two files Blink.nc & BlinkM.nc are required.

– Blink.nc is for configuration which uses many other components used 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



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; }



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” interface and “uses” interface

- In implementation block is for user programming- task (function w/o parameter) : declaration- StdControl init(), start(), stop() sequence.

- StdControl.init() calls Leds.init() to initialize LedsC.



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



LED Lab

Item:host PC(labtop), 1 mote , ISP(AVR), cable



LED lab -1• Start cygwin• Goto target directory

• Compile - make zigbex

cd /opt/tinyos‐1.x/contrib/zigbex cd Blink



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

Lab - 5• Check the message and graph



LED lab result• Output

– Yellow LED is con, every 30ms Green LED is toggling

– Please change source code to test RED.
