Press RB2 push button to display the remote temperature (PAN Coordinator):

• Remote Temp

• 010203: 21°C/ 70°F 

This demo uses the on-board MCP9700A Temperature Sensor. The readings are noted 
every 30 seconds and the information is broadcasted in the network. Both the nodes 
store the local and remote temperature data and display it on the LCD. 

To re-measure the temperature value, press RB0 push button on the PIC18 Wireless 
Development Board. This also initiates the broadcast message to all the nodes in the 
network. To scroll through the rotating display of local temperature and remote 
temperature, use RB2 push button on the PIC18 Wireless Development Board. The 
two node network can also be expanded to a multi-node network, for more information, 
see tutorial in 

All the Radio daughter cards have a MAC Address EEPROM. The 6 byte MAC Address 
in this EEPROM is used for the addressing scheme in MiWi.

The LCD Serial Accessory board can be used either in the SPI mode or I

2

C mode. This 

demo uses the LCD Serial Accessory Board in I

2

C mode. The demo uses manual back-

light mode versus the automatic backlight mode. With the manual backlight mode, the 
power consumption can be kept to the minimum.
