We have released a flexible API as a terminal tool to use the Si468x as a DAB processor in your projects.
The radio_cli named tool has the Si468x firmware compiled in. It allows control of all the main functions of the Si468x in a simple way. The tool saves you from worrying about the low-level functions when using the Si468x.
Booting up the Si468x now becomes as simple as running
./radio_cli --boot=D
and tuning to a station is simply
./radio_cli --frequency=11
Get more information from the instructions pdf or run
./radio_cli --help
