Examples

Here is a basic example to read the three day forecast data and report the information on a graphical display.

BBCWeatherForecastDemo

The location can be set by adjusting the BBC Weather location property, see the component property tooltips for more information on how to do this.

On an embedded device you would need a TCP/IP component to allow the communications to the BBC server. This then links to the Network Comms component.
