5.3 Radio Configuration File
5.3.1 Radio Initialization with RF Parameters
The radio parameter configuration process can be accomplished by using the Wireless Development Studio (WDS). After the required
parameters are given to the radio configuration application, WDS creates the configuration data based on these parameters. If the
Launch IDE option is selected, WDS generates a radio_config.h header file that contains the configuration data. This header file con-
tains all the information needed by the application to configure the radio properly. This information includes the parameters of the RF
link such as the modulation type, channel bandwidth, data rate, center frequency, crystal tolerance, crystal capacitor bank value, modu-
lation source, CRC calculation, and sync word setting. For more complete information on WDS and EZConfigPRO usage, refer to the
WDS User's Guide.
