Weather Station PC Application
The Freescale Weather Station PC application allows users to monitor simulated weather behavior using
a PC GUI application through the MC1322x SMAC network. This system setup uses two boards:
•
One board is connected to the PC through the serial interface to communicate with the GUI. This
board is a MC1322x Network Node running the embedded SMAC application and is used only as
a receiver.
•
The other board must be a MC1322x Sensor Node that transmits the information that it senses to
the Network Node receiver. The Sensor Node can monitor temperature, wind direction, wind
speed, air pressure, and battery voltage.

Features
The Freescale Weather Station PC application has the following features:
•
An easy-to-use graphical user interface
•
Real time visualization of the data frames of the devices in the network
•
Save log files with the weather information
•
Run in real time or from a previously saved file
•
Switch between different units of measure (metric or American/British)
•
Shows the maximum and minimum values obtained from each sensor during the demonstration
•
Shows the history of the weather behavior using bar graphics
