Zigbee Development Tutorial: A Comprehensive Guide for Beginners273

Zigbee is a wireless communication technology designed for low-power, low-data-rate applications. It is commonly used in home automation, industrial automation, and building automation systems. Zigbee devices form a mesh network, which allows them to communicate with each other in a self-organizing and self-healing manner. This makes Zigbee an ideal choice for applications where reliability and flexibility are essential.

In this tutorial, we will walk you through the steps of developing a Zigbee application. We will use the TI CC2650 microcontroller and the Zigbee 3.0 stack from Texas Instruments. We will cover the following topics:
Introduction to Zigbee
Setting up your development environment
Creating a new Zigbee project
Developing a Zigbee coordinator
Developing a Zigbee end device
Testing your Zigbee application

Introduction to Zigbee

Zigbee is a wireless communication technology that operates in the 2.4 GHz ISM band. It uses a mesh networking topology, which means that each device in the network can communicate with any other device in the network. This makes Zigbee an ideal choice for applications where devices need to be spread out over a large area.

Zigbee devices are typically low-power devices that can operate for years on a single battery. They are also very reliable, making them ideal for applications where data loss is unacceptable.

Setting Up Your Development Environment

Before you can start developing Zigbee applications, you need to set up your development environment. This includes installing the necessary software and hardware.

Software

The following software is required for Zigbee development:
TI Code Composer Studio (CCS)
Zigbee 3.0 stack from Texas Instruments

Hardware

The following hardware is required for Zigbee development:
TI CC2650 microcontroller
Zigbee module
USB cable

Creating a New Zigbee Project

Once you have set up your development environment, you can create a new Zigbee project. To do this, open CCS and click on the "File" menu. Then, select "New" and then "CCS Project".

In the "New CCS Project" dialog box, select the "Zigbee" tab. Then, select the "Zigbee 3.0" stack and the "TI CC2650" microcontroller. Click on the "Finish" button to create the project.

Developing a Zigbee Coordinator

A Zigbee coordinator is the central device in a Zigbee network. It is responsible for starting the network, managing the network, and routing data traffic. To develop a Zigbee coordinator, you need to create a new project and then add the following code to the main.c file:```c
#include
#include
#include
#include
#include
#include
#include
PIN_Handle ledPinHandle;
PIN_State ledPinState;
UART_Handle uartHandle;
UART_Params uartParams;
/* Task structures */
Task_Struct task0Struct;
Char task0Stack[1024];
/* Zigbee Stack Initialization */
void ZNPInit( void )
{
uint8_t retries = 10;
while (bdb_getZDOState() != BDB_STATE_RUNNING)
{
if (retries == 0)
{
/* Stack failed to start. */
System_abort("ZNP: Failed to start the Zigbee Stack.");
}
else
{
retries--;
Task_sleep( 1000 );
}
}
System_printf("Zigbee Coordinator is now running.");
}
/* Task 0 Function */
Void taskFxn0(UArg arg0, UArg arg1)
{
uint8_t keys;
System_printf("Press a key to toggle LED.");
while (1)
{
keys = UART_read(uartHandle, &keys, 1);
if (keys >= 0)
{
if (keys == '1')
{
PIN_setOutputValue(ledPinHandle, , !PIN_getOutputValue(ledPinHandle, ));
}
}
Task_sleep( 1000 );
}
}
/* Main Thread */
Int main( void )
{
/* Call driver init functions */
PIN_init( &ledPinState );
UART_init( &uartParams );
/* Configure the LED and UART pins */
ledPinHandle = PIN_open(&ledPinState, PIN_LED0);
if (ledPinHandle == NULL)
{
System_abort("Error initializing LED pin.");
}
PIN_setOutputValue(ledPinHandle, , 1);
uartHandle = UART_open(Board_UART0, &uartParams);
if (uartHandle == NULL)
{
System_abort("Error initializing UART.");
}
/* Create a task to toggle LED and handle user input */
Task_Params taskParams;
Task_Params_init(&taskParams);
taskParams.arg0 = (UArg)0;
= 1024;
Task_construct(&task0Struct, taskFxn0, &taskParams, NULL);
/* Start BIOS */
BIOS_start();
return(0);
}
```

Developing a Zigbee End Device

A Zigbee end device is a device that joins a Zigbee network and communicates with other devices on the network. To develop a Zigbee end device, you need to create a new project and then add the following code to the main.c file:```c
#include
#include
#include
#include
#include
#include
#include
PIN_Handle ledPinHandle;
PIN_State ledPinState;
UART_Handle uartHandle;
UART_Params uartParams;
/* Task structures */
Task_Struct task0Struct;
Char task0Stack[1024];
/* Zigbee Stack Initialization */
void ZNPInit( void )
{
uint8_t retries = 10;
while (bdb_getZDOState() != BDB_STATE_JOINED)
{
if (retries == 0)
{
/* Stack failed to start. */
System_abort("ZNP: Failed to start the Zigbee Stack.");
}
else
{
retries--;
Task_sleep( 1000 );
}
}
System_printf("Zigbee End Device is now running.");
}
/* Task 0 Function */
Void taskFxn0(UArg arg0, UArg arg1)
{
uint8_t keys;
System_printf("Press a key to toggle LED.");
while (1)
{
keys = UART_read(uartHandle, &keys, 1);
if (keys >= 0)
{
if (keys == '1')
{
PIN_setOutputValue(ledPinHandle, , !PIN_getOutputValue(ledPinHandle, ));
}
}
Task_sleep( 1000 );
}
}
/* Main Thread */
Int main( void )
{
/* Call driver init functions */
PIN_init( &ledPinState );
UART_init( &uartParams );
/* Configure the LED and UART pins */
ledPinHandle = PIN_open(&ledPinState, PIN_LED0);
if (ledPinHandle == NULL)
{
System_abort("Error initializing LED pin.");
}
PIN_setOutputValue(ledPinHandle, ,
