About this project

The main motivation for building this library was to allow the easy construction of FM, LW, MW and SW radios based on the Silicon Labs Si473X IC family.

This library was built based on Si47XX PROGRAMMING GUIDE; AN332. It also can be used on all members of the SI473X family respecting, of course, the features available for each IC version. These functionalities can be seen in the comparison matrix shown in table 1 (Product Family Function); pages 2 and 3 of the programming guide.
